Silica Gel Coarse (Product Code: SCL-989/237) is a coarse grade of porous silicon dioxide used as a drying agent in desiccators, balance cases and storage containers in chemistry and analytical laboratories. Listed as analytical reagent grade in a 500 gm pack with its MSDS, it can be regenerated by gentle oven heating and put back into service. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a lab consumables supplier in India.

Specifications

What Is Coarse Silica Gel Used For?

In gravimetric and volumetric work, a layer of the gel in the lower compartment of a desiccator lets hot crucibles, dried precipitates and oven-dried standard salts cool without picking moisture back up, so repeated weighings reach a constant value. A small open dish of the gel placed inside the case of an analytical or digital weighing balance keeps the weighing chamber dry, and a sachet in a jar of hygroscopic reagent slows caking between uses.

Once saturated, the gel can be regenerated by spreading it thinly in a shallow dish and heating it in a laboratory oven to drive off the absorbed water, then cooling it in a closed container before returning it to service. Coarse grades are meant for drying rather than column chromatography, which relies on much finer particles. Silica gel is chemically inert, but its dust irritates the airways and eyes, so pour it gently and keep it away from young children.

Frequently Asked Questions

Is Silica Gel Coarse self-indicating?
A colour-change indicator is not mentioned in the listing for Silica Gel Coarse. If you need an indicating type that shows when the gel is saturated, contact us to confirm what can be supplied before you place the order.

How is used Silica Gel Coarse regenerated?
Spread the saturated silica gel in a thin layer in a shallow dish, heat it in a laboratory oven until the absorbed moisture has been driven off, then cool it in a sealed container before returning it to the desiccator.

Can Silica Gel Coarse be packed into chromatography columns?
It is not intended for that. Silica Gel Coarse is sold as a desiccant, while column and thin-layer chromatography depend on much finer, graded particles, so ask us about suitable options for separation work.

What is the shelf life of Silica Gel Coarse?
Shelf life depends on the chemical, its grade and storage conditions, so no fixed period is given for Silica Gel Coarse. Ask us for the expiry date of the batch you are quoted, and keep the pack sealed so the gel does not load up with moisture.

Is Silica Gel Coarse hazardous?
Silica gel is chemically inert and of low hazard, though fine dust from Silica Gel Coarse can irritate the eyes and airways. It must not be eaten, so store it out of reach of young students and follow the MSDS supplied with the pack.

Tertiary Butyl Alcohol (Product Code: SCL-991/238) is an analytical reagent grade tertiary alcohol, also called tert-butanol or 2-methylpropan-2-ol, used to classify alcohols and demonstrate SN1 substitution in college and senior-school organic chemistry laboratories. It is the standard tertiary example in the Lucas and oxidation tests and comes in a 500 ml pack with its MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a lab chemicals supplier in India.

Specifications

What Is Tertiary Butyl Alcohol Used For?

To classify alcohols, students shake a few drops with Lucas reagent (zinc chloride in concentrated hydrochloric acid): tertiary butyl alcohol turns cloudy almost at once as the insoluble chloride separates, a secondary alcohol such as propan-2-ol clouds more slowly, and a primary alcohol shows little change at room temperature. With acidified potassium permanganate or dichromate the tertiary alcohol leaves the colour unchanged, because its central carbon carries no hydrogen to lose. Shaking it with concentrated hydrochloric acid in a separating funnel gives tert-butyl chloride, a clean classroom example of an SN1 reaction.

Its melting point lies close to room temperature, so the contents may be solid or partly solid in a cool store. Warm the closed bottle gently in a warm water bath, never over a flame, until it is fully liquid. The alcohol is highly flammable and its vapour irritates the eyes, so use it away from burners and in a well-ventilated room. An organic chemistry model kit helps students see why the three methyl groups crowd the central carbon and change its reactivity.

Supplier

This alcohol is supplied by Jain Scientific Equipments Private Limited, which does business as ScienceLab from Ambala, Haryana, India. Organic reagents and solvents are sourced for teaching and research laboratories, and flammable liquids are dispatched according to carrier rules for customers in India and international markets. See the company profile for more about ScienceLab.

Reagents and apparatus for alcohol classification practicals:

• Propane-2-ol — a secondary alcohol to compare in the Lucas and oxidation tests
• Hydrochloric Acid Cone. C.P grade — for Lucas reagent and the tert-butyl chloride preparation
• Potassium Permanganate — the oxidising agent that tertiary alcohols leave unchanged
• Water Bath — gentle, flame-free warming to re-liquefy the alcohol
• NCERT Molecular Model Kit — for building primary, secondary and tertiary alcohol structures

More organic reagents are available in the Chemistry Lab category.

Frequently Asked Questions

Why has the Tertiary Butyl Alcohol turned solid in the bottle?
Because tertiary butyl alcohol freezes at a temperature close to normal room temperature. Stand the closed bottle in warm water until the contents melt; the reagent is not spoiled by freezing, but never warm it over a flame.

How does Tertiary Butyl Alcohol respond in the Lucas test?
Tertiary butyl alcohol turns Lucas reagent cloudy almost immediately as the insoluble chloride separates, the classic sign of a tertiary alcohol, which distinguishes it from secondary alcohols that react slowly and primary alcohols that barely react at room temperature.

Will acidified dichromate oxidise Tertiary Butyl Alcohol?
Not under normal laboratory conditions. With tertiary butyl alcohol the orange dichromate colour remains, because its central carbon carries no hydrogen to lose, while primary and secondary alcohols turn the reagent green.

How should Tertiary Butyl Alcohol be stored?
Store tertiary butyl alcohol in a tightly closed container inside a flammables cabinet, away from heat, sparks and oxidising agents. The MSDS supplied with the 500 ml pack details fire-fighting measures, first aid and safe disposal.

What is the shelf life of Tertiary Butyl Alcohol?
No blanket shelf life is stated for tertiary butyl alcohol, because shelf life depends on the chemical, its grade and storage conditions. Ask us for the expiry date of the batch you are quoted, and keep the cap tight to limit evaporation.

Who supplies Tertiary Butyl Alcohol?
Tertiary Butyl Alcohol is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, Ambala, Haryana, India, in 500 ml analytical reagent packs with an MSDS, for colleges, universities and senior-school laboratories in India and international markets.

Can Tertiary Butyl Alcohol be sent to customers outside India?
It can be, subject to transport rules. As a flammable liquid, tertiary butyl alcohol is regulated in transit, so export depends on the destination and carrier; share your requirement through the contact page for a confirmed answer.

Tollens Reagent (Product Code: SCL-993/239) is the ammoniacal silver reagent used to distinguish aldehydes from ketones by the silver mirror test in college, university and senior-school organic chemistry laboratories. Aldehydes and reducing sugars deposit a bright silver mirror while ketones leave it unchanged, making it a natural partner to a Fehling solution kit; it is listed in a 500 ml analytical reagent pack with its MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is Tollens Reagent Used For?

For the test, a few drops of the sample are added to the reagent in a scrupulously clean test tube, which is then warmed in a water bath rather than over a flame. A silver mirror, or at least a grey-black silver deposit, indicates an aldehyde or a reducing sugar such as glucose; acetone and other simple ketones give no change. Because the reagent is built on silver nitrate solution made alkaline and complexed with ammonia, it also complements Fehling solution: aromatic aldehydes such as benzaldehyde reduce Tollens reagent but not Fehling solution, helping students tell aromatic from aliphatic aldehydes.

Safety matters with this reagent. The mixed ammoniacal silver solution must be prepared or used immediately before the test and never kept, because on standing it can deposit dangerously explosive silver compounds. Discard the contents of each tube straight after observation, acidifying with dilute acid before rinsing away as the MSDS and local rules direct. Silver salts stain skin black, so wear gloves and goggles, and keep the reagent away from light.

Supplier

Tollens Reagent is supplied by Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana, India, to colleges, universities, schools and distributors in India and international markets. For vendor registration, purchase departments can record the supplying company's GSTIN 06AAECJ8618A1ZT and its Legal Entity Identifier 3358004HRD1JIVXKYX49. Our company profile has further details.

Frequently Asked Questions

Is Tollens Reagent supplied ready-mixed or in separate parts?
The current listing for Tollens Reagent does not specify the supplied form of the 500 ml pack. Please contact us to confirm whether it comes ready to use or as components before ordering, so your practical can be planned accordingly.

Can prepared Tollens Reagent be stored for later?
No. Once the ammoniacal silver solution of Tollens reagent is made up, use it in the same session and dispose of any leftover straight away, because mixtures left standing can form dangerously explosive silver deposits.

Why did Tollens Reagent give a black precipitate instead of a mirror?
A greasy test tube or overheating usually causes it. Clean the tube thoroughly, rinse with distilled water and warm it gently in a water bath; a grey-black silver deposit from Tollens reagent still counts as a positive result.

How is the silver mirror from Tollens Reagent removed from glassware?
Rinse the tube promptly with dilute nitric acid in a fume cupboard, then wash it with water. Silver residues from Tollens reagent should never be left standing in tubes, and the washings should be disposed of as the MSDS directs.

What is the shelf life of Tollens Reagent?
Shelf life depends on the chemical, its grade and storage conditions, so no blanket period is stated for Tollens Reagent. Ask us for the expiry date of the batch you are quoted; any mixed working solution must be used immediately and never stored.

Who supplies Tollens Reagent?
Tollens Reagent is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, in a 500 ml analytical reagent pack with an MSDS, for organic chemistry and biochemistry practicals in India and international markets.

Universal Indicator (pH) (Product Code: SCL-996/241) is a laboratory-grade universal indicator solution used to estimate the approximate pH of liquids by colour in school, college and research chemistry laboratories. Unlike litmus, it gives a graded range of colours across acids and alkalis, and each 500 ml bottle carries safe handling and storage procedures printed directly on it. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, for buyers of universal indicator solution in India.

Specifications

What Is Universal Indicator Used For?

A universal indicator is a blend of indicators, so a single drop or two gives a graded colour rather than the simple two-colour switch of litmus. In a typical class activity, students place a few millilitres of each test liquid (dilute acid, tap water, soap solution, dilute alkali) in separate test tubes or wells of a spotting tile, add the indicator dropwise and compare the colour against a pH chart to rank the samples from strongly acidic to strongly alkaline. It is equally useful for showing how the colour drifts during a neutralisation, which is why it anchors almost every acid base indicator kit used in classrooms.

For practical work, decant a small working quantity into dropper bottles for each bench rather than passing the 500 ml stock bottle around; this keeps the main supply clean and reduces spills. Read the colour against a white background, use the same number of drops for every sample so results can be compared fairly, and keep the cap closed between uses. Follow the storage and handling instructions printed on the bottle and in the MSDS, and use eye protection when handling acids and alkalis during testing.

Supplier

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, based in Ambala, Haryana, India, which supplies Universal Indicator (pH) to schools, colleges and research institutions. Indicators, pH papers and related reagents can be quoted in one enquiry for delivery in India and international markets. Read more on the company profile.

• Dropper Bottle, 10 ml — for dispensing small bench quantities from the stock bottle
• Chemical Splash Protection Goggle — eye protection while testing acids and alkalis

See the full Chemistry Lab category for more reagents, charts and apparatus.

Frequently Asked Questions

How much Universal Indicator (pH) is in one bottle?
Each bottle of Universal Indicator (pH) holds 500 ml. Most labs decant small working quantities into dropper bottles for each bench, so one stock bottle can serve several classes; mention the number of bottles needed when you send an enquiry.

Is safety information included with Universal Indicator (pH)?
Yes. Universal Indicator (pH) is supplied with an MSDS, and safe handling and storage procedures are printed directly on each bottle, so the key precautions stay with the reagent wherever it is kept.

How is Universal Indicator (pH) different from litmus?
Universal indicator is a blend of indicators that shows a graded series of colours matched against a pH chart, whereas litmus only switches between red and blue. Universal Indicator (pH) therefore ranks samples from strongly acidic to strongly alkaline rather than just sorting them.

What is the shelf life of Universal Indicator (pH)?
Shelf life depends on the chemical, its grade and storage conditions, so no fixed period is quoted for Universal Indicator (pH). Ask us for the expiry date of the batch you are quoted, and follow the storage directions printed on the bottle.

Can Universal Indicator (pH) be used to test food, medicines or at home?
No. Universal Indicator (pH) is designed for laboratory or educational use only and is not for food, drug or home use, so it should stay in the school or college laboratory under staff supervision.

Who supplies Universal Indicator (pH)?
Universal Indicator (pH) is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, in 500 ml bottles with an MSDS, for school, college and research laboratories and distributors in India and international markets.

Potassium Ferrocyanide (Product Code: SCL-931/208) is an analytical reagent, also known as potassium hexacyanoferrate(II), used to confirm metal ions such as iron(III), copper(II) and zinc in qualitative salt analysis in senior secondary, college and teaching laboratories. Chemistry teachers and lab assistants order it in 500 gm packs supplied with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a lab chemicals supplier in India.

Specifications

What Is Potassium Ferrocyanide Used For?

In the practical syllabus, a freshly prepared aqueous solution of potassium ferrocyanide is added dropwise to the salt solution under test. A deep blue precipitate (Prussian blue) points to iron(III) ions, while a chocolate-brown precipitate is characteristic of copper(II); it is also used in the confirmatory test for zinc. Because the result depends on a clear colour change, students should work with clean test tubes, add the reagent slowly and compare against a known sample where possible. Teachers running salt analysis for a whole batch usually prepare one stock solution for the session and discard leftovers rather than storing them for long periods.

The solid should be kept tightly closed in a cool, dry place, away from strong acids: mixing ferrocyanides with strong acids, especially when heated, can release toxic gas, so tests should be done in a well-ventilated area and waste collected as directed in the MSDS. For schools and colleges that want a single chemistry consumables supplier in India for reagents and apparatus, this reagent can be quoted together with glassware, racks and safety items.

Supplier

Potassium Ferrocyanide is supplied by Jain Scientific Equipments Private Limited, the Ambala, Haryana company that trades as ScienceLab.

Fortin Barometer (Product Code: SCL-268/032) is a mercury barometer used to measure atmospheric pressure precisely in school and college physics laboratories. Before each reading the mercury in the cistern is set to a fixed zero called the fiducial point, and the column height is then read on a clear linear scale with a vernier, which makes it a classic teaching item among physics lab instruments. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is a Fortin Barometer Used For?

A Fortin Barometer shows atmospheric pressure as the height of a mercury column. Because the space above the column has been emptied of air, only the pressure of the atmosphere on the cistern holds the mercury up, which makes it an effective way to teach Torricelli's principle. Labs also use the day's reading when working on gas-law practicals or correcting boiling-point measurements taken with a hypsometer.

To take a reading, turn the adjusting screw until the mercury surface in the cistern just meets the fiducial point, then set the vernier to the top of the mercury column at eye level and add the vernier reading to the main scale value. Note the room temperature with each reading, as precise barometer readings are normally corrected for it. Mount the instrument where students cannot knock it, and follow your institution's mercury-handling rules for any spill.

OEM Manufacturer

Jain Scientific Equipments Private Limited, known by its ScienceLab brand, is the OEM (original equipment manufacturer) of this Fortin Barometer and makes it at its own licensed factory at Saha, Ambala, Haryana, India. Buying from the manufacturer means installation and handling questions go straight to the maker, and replacement parts can be requested from the same source; ask us about availability. Schools, colleges, dealers and importers all receive quotations factory-direct. Learn more on the ScienceLab profile page.

Related Physics Lab Equipment

These items are commonly used alongside a Fortin Barometer for pressure and heat practicals:

• Aneroid Barometer — a mercury-free barometer for comparison readings
• Metal Barometer — another barometer option for the lab or classroom
• Hypsometer — boiling-point work that needs the day's pressure reading
• Plumb Line Level — to check that the barometer hangs truly vertical

Browse the Physics Lab category for more instruments.

Frequently Asked Questions

How does a Fortin Barometer work?
A Fortin Barometer balances atmospheric pressure against a column of mercury. Air is evacuated from the top of the tube and its lower end sits in a mercury cistern, so the height of the column read on the scale indicates the atmospheric pressure.

What is the fiducial point on a Fortin Barometer?
The fiducial point on a Fortin Barometer is the scale zero. Before every reading, the mercury level in the glass at the bottom of the cistern is adjusted to meet it, so each column reading starts from the same reference level.

How precise are Fortin Barometer readings?
The Fortin Barometer uses a vernier adjustment on its clear linear scale for extra reading accuracy. For the vernier least count and scale units of the model you are quoted, please ask us through the contact page.

How should a Fortin Barometer be moved after installation?
To move a Fortin Barometer, turn the adjustment screw until mercury fills the reservoir and the column is about 25 mm from the top of the scale. Lift it off the wall, tilt it gently and lay it flat, then turn the screw further until a small air gap remains in the reservoir.

How should a Fortin Barometer be carried and re-hung?
A Fortin Barometer can be moved without risk of damage as long as it is always carried flat or upside down. To re-hang it on the wall or pillar, reverse the moving procedure step by step before taking the next reading.

Is mercury included with the Fortin Barometer?
How the Fortin Barometer is dispatched, including its mercury, should be confirmed with us before ordering, since transport rules for mercury differ by destination. Ask through the contact page and the details will be stated in your quotation.

Who manufactures the Fortin Barometer?

Plumb Line Level (Product Code: SCL-272/034) is a brass plumb weight, hung on a line, used to establish a true vertical in school and college physics laboratories. Teachers and students use it to check that stands, scales and hanging apparatus are upright and to trace vertical lines in the centre of gravity experiment; the brass body is compact and dense, so it settles steadily. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is a Plumb Line Level Used For?

Gravity pulls the hanging weight straight down, so the line marks the local vertical. In the classic experiment to find the centre of gravity of an irregular lamina, the lamina is hung from a pin, the plumb line is hung from the same pin, and the line is traced on the lamina; repeating this from a second hole gives two lines that cross at the centre of gravity. The same tool checks that Searle's apparatus, a wall-mounted barometer or a vertical meter scale is truly upright before readings begin.

Let the weight come fully to rest before marking, and keep it away from fans and open windows that make it swing. Keep the line free of knots and kinks, since they shift where the weight hangs. Brass does not rust as iron does, though it can tarnish, so an occasional wipe with a dry cloth keeps it tidy.

OEM Manufacturer

The Plumb Line Level is manufactured by Jain Scientific Equipments Private Limited, which trades as ScienceLab and is the OEM for its own range of physics lab items. It is made at the company's licensed factory at Saha, Ambala, Haryana, India, and schools, colleges, dealers and importers buy it factory-direct, with repeat and bulk orders quoted by the manufacturer itself. Tender and vendor-registration teams can note the company's CIN, U29309HR2020PTC087597, and Factory Licence AMB-ONLINE-CHD-J-414 for its premises at 449, HSIIDC Industrial Area, Saha, Ambala.

Explore the full Physics Lab category.

Frequently Asked Questions

What is the Plumb Line Level made of?
The Plumb Line Level (code SCL-272/034) is made of brass. Brass is dense, so the weight hangs steadily on its line, and it does not rust as iron does, though it may tarnish over time with handling.

Is the line included with the Plumb Line Level?
What comes with the Plumb Line Level, including the line or cord, should be confirmed with us before ordering. Mention it on the contact page and the contents will be stated in your quotation.

How is a Plumb Line Level used to find the centre of gravity?
To find the centre of gravity of an irregular lamina with a Plumb Line Level, hang the lamina and the plumb line from the same pin and trace the line. Repeat from a second hole; where the two lines cross is the centre of gravity.

What is the difference between a Plumb Line Level and a spirit level?
A Plumb Line Level shows the true vertical through gravity acting on a hanging brass weight, while a spirit level uses an air bubble in a liquid vial to check that a surface is horizontal. Many labs keep both for setting up apparatus.

Who manufactures the Plumb Line Level?
Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, manufactures the Plumb Line Level as the OEM at its own factory in Saha, Ambala, Haryana, India, and sells it factory-direct to institutions and dealers.

Rising Table (Product Code: SCL-276/036) is a height-adjustable laboratory stand used to raise a vessel of liquid to a capillary tube in the surface tension of liquid by capillary rise method. Physics students in senior school and college use it as the base of this surface tension apparatus, and it comes complete with a capillary tube clamp and a side rod attachment. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is a Rising Table Used For?

In the capillary tube experiment, a clean capillary is held vertical in the clamp with its lower end dipping into water in a beaker standing on the rising table. Water climbs the narrow bore to a height that depends on the liquid's surface tension, and a travelling microscope is used to read the meniscus. The side rod attachment is typically used to carry a pointer set just touching the liquid surface, so the table can then be lowered and the microscope sighted on the pointer tip to fix the level of the free surface.

Surface tension is then calculated from the rise height, the bore radius, the liquid's density and the acceleration due to gravity. For steady results, clean the capillary well, since grease spoils the meniscus, wet the bore before the reading, raise or lower the table slowly so the column is not disturbed, and note the water temperature, because surface tension changes with it.

OEM Manufacturer

ScienceLab is the brand of Jain Scientific Equipments Private Limited, the OEM (original equipment manufacturer) that builds this Rising Table, clamp and side rod set at its own licensed factory at Saha, Ambala, Haryana, India. Labs that need several stations for a practical batch, or a replacement clamp for an existing table, can raise it with the manufacturer directly; ask us. Quotations for schools, colleges, dealers and importers come factory-direct. Company information is on the ScienceLab profile page.
