The Colorimeter (Product Code: SLE/CH/110) is a compact bench instrument that measures how strongly a coloured solution absorbs light, so students can link the depth of a colour to the concentration of the substance that causes it. It has been designed for educational establishments such as schools and colleges: it is lightweight, ergonomically shaped to withstand student handling, and fitted with a large display that is easy to read from across a bench. Manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, it is one of the analytical lab instruments India teaching laboratories use to introduce quantitative light-absorption work.

Specifications

Typical Use

The classic student investigation is a calibration curve: learners prepare a dilution series of a coloured solution, record a reading for each standard, plot reading against concentration, and then use the graph to find the concentration of an unknown sample. The same instrument supports reaction-rate work, where a solution that changes colour or turns cloudy is read at regular intervals, and simple biology practicals that follow a colour change produced by an indicator or an enzyme reaction. Because it gives rapid results and is quick to set up, several groups can share one unit during a busy practical period.

For reliable readings, zero the instrument with a blank of the solvent in the same type of container used for the samples, wipe the clear faces of each cuvette with a lint-free tissue, and always insert the cuvette facing the same way. Using 16mm test tubes directly saves a transfer step when a whole class is measuring many samples. Institutions that source their chemistry lab instruments supplier-direct from us often order transfer pipettes and racks with the colorimeter so each station is complete.

The Comboplate, Microscience (Product Code: SLE/CH/111) is a transparent 60-well plate on which students run chemistry, biology and physics experiments with drops of reagent instead of full test tubes. Its 48 small wells behave like “micro test tubes” and its 12 large wells like “micro beakers”, and every well is labelled by a grid reference so results can be recorded precisely. Manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, it is a practical piece of chemistry lab equipment for schools in India that want to run microscale practicals across a whole class.

Specifications

Typical Use

A favourite first lesson is acids and bases: a row of small wells receives a drop of indicator, students add acid or alkali drop by drop, and the colour changes are logged against each grid reference. Because the plate is completely transparent, a teacher can place it on an overhead projector and the whole class sees the colours develop at the same time. Microtitrations work the same way, with drops counted instead of burette readings, while the 12 larger wells take reactions that need a little more volume or mixing space, such as displacement reactions or small gas-producing tests.

The plate also serves as the base for other components of the Microscience System, so it pairs naturally with a titration kit for school use in India built around the same approach. After the practical, rinse the wells promptly so residues do not dry on, then wash the plate in a dishwasher and reuse it for the next class. Recording results by grid reference (for example, row and column) helps students write up methods that someone else could repeat exactly.

The Inner Reaction Vessel (Product Code: SLE/CH/112) is a slim, small-volume container with a 5 ml capacity, measuring 50 mm in height and 14 mm in diameter. In small-scale chemistry, a vessel of this kind is typically used to hold a few millilitres of one reactant inside a larger container or apparatus, so that the reaction can be started, contained and observed with only a small quantity of chemicals. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, and joins the wider range of chemistry lab equipment India schools and colleges use for microscale practicals.

Specifications

Typical Use

Working at the 5 ml scale lets a class repeat a reaction several times in one lesson while keeping chemical use, waste and clean-up to a minimum. Teachers use small inner vessels to keep a reagent apart until the moment it is needed, to confine a reaction whose gas or colour change is then watched in a surrounding container, or simply as compact reaction tubes when bench space is limited. The narrow 14 mm body keeps the liquid column tall, which makes small colour changes and bubbling easier to see.

Measure reagents into the vessel with a dropper or a small graduated pipette rather than pouring, and stand it securely before adding anything so it cannot tip. Because the material is not stated in our current notes, check with us before heating the vessel or using strong solvents. Clean it promptly with a narrow brush and leave it inverted to dry. It is a useful spare to keep with any chemistry experiment kit India teachers run at microscale.

Manufacturer

Consumer Chemistry Science Kit (Product Code: SLE/CH/113) is a kitchen-themed chemistry kit used to teach chromatography, chemical identification tests, enzyme action, titration and the chemistry of cleaning products in school and college labs. It contains enough materials for fifteen groups, so a full class can work through each technique using materials found in an ordinary kitchen. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as a chemistry teaching kit for integrated science courses.

Key Details

What Is the Consumer Chemistry Science Kit Used For?

Most teachers spread the activities over a short sequence of practical lessons, each introducing a different technique. The food-colour chromatography shows that one commercial colour can contain several dyes; the chemical tests train students to reason from observations to name an unknown ingredient; the meat-tenderiser activity turns protein digestion into something visible; the vitamin C titration develops careful end-point judgement; and the detergent comparison links structure to cleaning action.

Students can bring in a juice or soda of their own for the final vitamin C test, which gives the unit a satisfying real-world ending. Give each of the fifteen groups a labelled tray, keep the enzyme activity away from heat sources until it is needed, and collect results in a shared table so class data can be compared. Because the investigations draw on both chemistry and biology, schools often run it with other themed chemistry experiment kits in India so a single topic, such as food science, carries across a term.

Supplier

This kit is supplied by Jain Scientific Equipments Private Limited, the Ambala, Haryana company behind the ScienceLab name. It sources investigation kits and consumables for schools, colleges and distributors in India and international markets, and can quote this kit together with extra chromatography paper, burettes and beakers. Learn more on our company profile.

Related Chemistry Lab Equipment

Items that extend or support these kitchen-chemistry investigations:

• Chromatography Paper No. 1 — extra paper for repeating the food-colour separations
• Micro Burettes, Class-A — for finer volume readings if the vitamin C titration is extended
• Glass Beaker Set of 5 — general containers for preparing and holding test solutions
• Environmental Chemistry: Water Treatment & Filtration — another themed kit linking chemistry to daily life
• Organic Chemistry Kit — a follow-on kit for classes moving into organic reactions

Explore more kits in our Chemistry Lab Equipment range.

Frequently Asked Questions

How many groups can use one Consumer Chemistry Science Kit?
One Consumer Chemistry Science Kit contains enough materials for fifteen groups, so a typical class can carry out each kitchen-themed investigation in small teams rather than watching a single demonstration.

Is the juice or soda for the vitamin C test included?
No. The unknown juice or soda for the vitamin C titration is not provided with the Consumer Chemistry Science Kit, so students or teachers bring their own drink to test at the end of the unit.

Which techniques does the kit cover?
The Consumer Chemistry Science Kit covers chromatography of commercial food colours, chemical tests to identify an unknown cooking ingredient, the protein-digesting action of a meat tenderizing enzyme, vitamin C titration, and a comparison of soap with hand and machine dishwashing detergents.

Where can I see the full list of components?
A detailed component list for the Consumer Chemistry Science Kit is not part of our current product notes. Request it through our contact page and we will share it with your quotation so you can check it against your syllabus.

What is the shelf life of the kit?
The shelf life of the Consumer Chemistry Science Kit depends on the chemicals and other contents, their grade and storage conditions; ask us for the expiry date of the batch you are quoted, and keep the kit closed in a cool, dry cupboard.

Which class level is it suitable for?
The Consumer Chemistry Science Kit includes titration and enzyme work, so it suits supervised laboratory classes; compare the five investigations with your syllabus, and ask us through the contact page if you need help matching them.

Crime Scene Investigation (Product Code: SLE/CH/114) is a forensic science activity that lets students explore how criminal investigations actually work, from the first look at a crime scene to naming a likely suspect. Learners examine physical evidence, identify the victim through dental records and fingerprints, run tests on what they collect and work out the cause of death. With materials for up to 40 students, it is a STEM science kit India classrooms can use to connect chemistry and biology to a story students want to solve. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Key Details

Typical Use

Teachers usually stage the activity as a mock case. A corner of the lab is marked off as the scene, teams of students take on roles such as scene examiner, evidence recorder and laboratory analyst, and every item they collect is labelled and logged before testing. Matching dental records and fingerprints teaches careful comparison and observation, while the evidence tests and cause-of-death analysis give practice in carrying out procedures and interpreting results. The investigation ends with each team presenting its case for a suspect and defending it with evidence, which builds scientific reasoning and communication at the same time.

For a class of up to 40, dividing students into small teams that rotate between evidence stations keeps everyone busy. Provide gloves and eye protection during the testing stage, and review the scenario in advance so it suits the age of your group. As a school science kit supplier in India, we find many schools run this investigation during science weeks or as the final project of a forensics unit.

Supplier

Jain Scientific Equipments Private Limited, trading as ScienceLab, supplies this investigation from its base in Ambala, Haryana, India. The company manufactures laboratory apparatus and also provides teaching kits and consumables for schools and colleges. See our company profile for more about who we are.

Crime Scene Investigation – Forensic Chemistry Of Whodunit (Product Code: SLE/CH/115) is a forensic chemistry case in which students solve the crime of the missing frogs. Four possible suspects have been identified, and the class uses fingerprints, hair examination and chemical analysis of ink by Thin-Layer Chromatography to decide who is most likely responsible. With material for 6 groups and printed teaching resources, it doubles as a story-led chromatography kit for school India laboratories. The activity is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Key Details

Typical Use

The lesson opens with the mystery: frogs have gone missing and four suspects are in the frame. Each of the 6 groups works through three lines of evidence. Fingerprint comparison narrows the field by pattern type, hair examination adds physical evidence that must be compared carefully, and the ink analysis brings in real chemistry, as students spot ink samples on a TLC plate, develop it and compare the separated bands with ink linked to each suspect. No single test is decisive on its own, so groups must weigh all three results before naming the most likely culprit, which mirrors how forensic scientists build a case.

The Teacher’s Manual sets out the running of the activity, while the Student Guide and Analysis copy-masters can be photocopied so every learner records observations in the same format. For teachers who prefer a science kit with manual India syllabuses can map onto, this makes preparation straightforward. Run the TLC stage in a ventilated area with solvent jars covered, and ask groups to present their verdict with evidence at the end of the session.

Supplier

This forensic activity is supplied by Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana, India, and also manufactures laboratory apparatus for education. Buyers completing vendor registration can use the company’s GSTIN 06AAECJ8618A1ZT and its Legal Entity Identifier, LEI 3358004HRD1JIVXKYX49. More details are on our company profile.

Crime Scene Tape (Product Code: SLE/CH/116) is a bright yellow roll of barrier tape, 30 m long, made for forensics crime scene lessons. Stretched across a doorway or around a set of benches, it instantly turns part of a classroom into a “scene” that students must investigate carefully and must not disturb. It is a small item from our school lab equipment supplier India range that adds realism to forensic activities, and it is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Specifications

Typical Use

Teachers tie the tape between retort stands, chair backs or door handles to mark the boundary of a mock crime scene before students arrive. The boundary does real teaching work: only the “scene examiners” may cross it, evidence must be photographed or sketched before anything is moved, and students learn why preserving a scene matters in forensic science. A 30 m roll is long enough to cordon off several separate scenes, so different teams can each have their own area during a single lesson.

The tape also makes an eye-catching border for forensic displays at open days and for a science fair project kit India students assemble around crime-solving themes. After the lesson, roll unused or undamaged lengths back up for the next class. Keep it for teaching scenarios only; genuine hazards in a laboratory should be marked with dedicated hazard warning tape so the two messages are never confused.

Supplier

Crime Scene Tape is supplied by Jain Scientific Equipments Private Limited, whose products are sold under the ScienceLab name. The company is headquartered in Ambala, Haryana, India, where it manufactures laboratory apparatus and provides supporting classroom supplies. Read our company profile for background.

The Current Indicator LED (Product Code: SLE/CH/117) is a light-emitting diode indicator used to show, at a glance, whether an electric current is flowing in a circuit. In a chemistry classroom it is most often connected in series with a solution or a simple cell, so students can see immediately whether a liquid conducts or whether a cell is producing current. It is a simple companion to any electrochemical cell kit school laboratories use, and it is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Key Details

Typical Use

A common practical places the indicator in series with a low-voltage supply and a pair of electrodes dipped into different liquids. Tap water, salt solution, sugar solution and dilute acid can be tested in turn: where the LED lights, the liquid contains mobile ions and conducts; where it stays dark, it does not. Comparing how brightly the indicator glows gives a quick, qualitative sense of stronger and weaker electrolytes before students move on to measured readings with a meter. The same indicator can confirm that a home-made cell, such as two different metals in an electrolyte, is actually delivering current.

Like all LEDs, the indicator conducts in one direction only, so if it fails to light in a working circuit, reverse the connections before assuming there is no current. Use low-voltage supplies, keep connections dry and away from the liquid being tested, and rinse the electrodes between samples to avoid carry-over. It is a handy first step before setting up the electrolysis apparatus India schools use for decomposing solutions, because it shows students that current is flowing before products begin to form.

Manufacturer

The Current Indicator LED is manufactured by Jain Scientific Equipments Private Limited, which operates under the brand ScienceLab from Ambala, Haryana, India. The company supplies laboratory equipment to schools, colleges and technical institutes. Find out more on our company profile.

Related Chemistry Lab Equipment

Equipment used in the same conductivity and electrochemistry practicals:

• Conductivity Demonstrator — a ready-made set-up for comparing the conductivity of solutions
• Conductivity of Solutions Apparatus — electrodes and holder for testing liquids in turn
• Crocodile Clips & Leads — quick connections between the indicator, electrodes and supply
• Battery Holder, C — a simple low-voltage source for the test circuit
• Brownlee Electrolysis Apparatus — the next step once students have seen that solutions conduct

See more in our Chemistry Lab Equipment category.

Frequently Asked Questions

What does the Current Indicator LED show?
It lights up when current flows through the circuit it is connected to, giving a clear yes-or-no signal for conductivity and cell tests.

What operating voltage and current does it need?
The electrical ratings are not published in our current product notes. Please request them through our contact page so you can match the indicator to your power source.

Why doesn’t it light even though the circuit is complete?
An LED only conducts in one direction. Swap the two connections; if it still stays dark, check the supply and the electrode contacts.

Does it have built-in current limiting?
This is not stated in our documentation. Confirm with us before connecting it directly to a supply without a series resistor.

Can it tell strong and weak electrolytes apart?
Only roughly, through differences in brightness. For measured values, use an ammeter or conductivity meter alongside it.

Can you supply class quantities or export orders?
Yes. We quote class sets and larger orders for schools and distributors in India and international markets.
