Apparatus for Demonstrating Electrolytic Processes (Product Code: SCI-073/012) is an electrolysis apparatus used to show how an electric current drives chemical change in solutions in school and college chemistry laboratories. Teachers use it to compare five electrode materials — carbon, copper, zinc, lead and brass — in 10% sulfuric acid or copper sulfate solution, with a bulb showing when current flows. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Electrolytic Processes Apparatus Used For?

In a typical lesson the beaker is filled with one of the two solutions, a pair of electrodes is clamped in the supports and the circuit is completed through the bulb and conductor wires to a low-voltage DC source. The glowing bulb shows that the solution conducts; with carbon electrodes in copper sulfate, a copper layer builds up on the cathode, while the dilute sulfuric acid gives gas bubbles at the electrodes. Swapping in copper, zinc, lead or brass lets students compare inert and reactive electrodes.

This piece of school chemistry lab equipment calls for basic care: the sulfuric acid solution is corrosive, so students should wear eye protection and gloves, and everyone should wash their hands after handling the lead electrodes. Keep the solutions capped and labelled, and rinse the beaker and electrodes after every class.

What to Specify When Ordering

• The number of sets, for example one per student bench.
• Whether you need extra quantities of the sulfuric acid or copper sulfate solution for repeat classes.
• Whether a suitable low-voltage DC source should be discussed in the same quotation, as none is listed in the contents.
• Any spare electrodes of a particular material (ask us about availability).

Vacuum Filtration Equipment (Product Code: SCI-077/014) is a suction filtration set used to separate solids from liquids quickly under reduced pressure in school and college chemistry laboratories. It brings together a conical flask with side tube, a porcelain Büchner funnel, a water pump for vacuum and a three-nozzle Woulff bottle, so students can collect crystals and precipitates much faster than by gravity filtration. This chemistry lab equipment is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Vacuum Filtration Set Used For?

The Büchner funnel sits in a rubber stopper on the side-tube flask, and the side tube is connected by tubing to the Woulff bottle and then to the water pump on a running tap. The fast water stream draws air out of the system, so the liquid is pulled through the filter paper while the solid stays on the paper as a compact, easily washed cake. The Woulff bottle works as a trap that stops tap water being sucked back into the filtrate if the water pressure drops.

Typical uses include collecting crystals after recrystallisation, washing precipitates and separating solids in preparation experiments, which makes the set standard lab equipment for college practical courses. Lay a filter paper circle flat over all the funnel holes and wet it before pouring, and always disconnect the tubing before closing the tap.

What to Specify When Ordering

• The number of complete sets for your laboratory.
• Whether filter paper should be quoted too (ask us to confirm the circle size that suits the funnel).
• Any spare rubber tubes, stoppers or funnels you want for heavy use (ask us about availability).

OEM Manufacturer

ScienceLab — legally Jain Scientific Equipments Private Limited — is the OEM for this vacuum filtration set, which is produced at the company's own licensed factory at Saha, Ambala, Haryana, India. Laboratories that buy from the source receive one quotation for the complete set.

You can also return to the same manufacturer for replacement tubes, stoppers or funnels and for repeat orders, whether you are a school, a dealer or an importer. Read more on our company profile.

Frequently Asked Questions

What is included in the Vacuum Filtration Equipment?
The Vacuum Filtration Equipment includes a conical flask with side tube, a porcelain Büchner funnel (hopper) for vacuum filtration, a water pump for vacuum, a three-nozzle Woulff bottle, rubber tubes, plastic pipes and rubber stoppers. Filter paper is not part of the listed contents.

How does the water pump in this set create a vacuum?
The water pump in the Vacuum Filtration Equipment is fitted to a running tap. Water rushing through its narrow nozzle drags air out of the side tube, lowering the pressure inside the flask so the liquid is pulled rapidly through the filter paper.

Why does the vacuum filtration set include a Woulff bottle?
The three-nozzle Woulff bottle in the Vacuum Filtration Equipment sits between the flask and the water pump as a safety trap. If the tap pressure drops, any water sucked back collects in the bottle instead of spoiling the filtrate in the flask.

Which filter paper suits the Vacuum Filtration Equipment?
Use a filter paper circle that lies flat on the perforated plate of the funnel and covers every hole without climbing the walls. The funnel diameter of the Vacuum Filtration Equipment is not listed here, so ask us to confirm the matching size.

Who manufactures the Vacuum Filtration Equipment?
Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, is the OEM manufacturer of the Vacuum Filtration Equipment. The set is made at the company's own licensed factory at Saha, Ambala, Haryana, India, and supplied factory-direct to institutions, dealers and importers.

What should I send for a bulk or export quotation?

Metal Barometer (Product Code: SCI-093/021) is a mercury-free barometer used to measure atmospheric pressure in school physics, geography and weather-study lessons. Students read pressure changes on its dial, and the instrument has a 90 mm base diameter with a 57 mm field (dial) diameter. As part of the physics lab equipment range, it is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is a Metal Barometer Used For?

A metal barometer works on the aneroid principle: a sealed, partly evacuated metal capsule flexes slightly as air pressure changes, and a linkage turns the pointer across the dial. In class, students log readings over several days and link falling pressure with unsettled weather and rising pressure with fair conditions. Carrying the instrument between floors of a tall building also shows how pressure drops with height.

For schools building a weather corner, it is a practical item of geography lab equipment alongside a thermometer and a humidity meter. Tap the case gently before each reading to free the pointer, and keep the barometer away from heaters, direct sunlight and draughts so that temperature changes do not disturb the result.

OEM Manufacturer

The Metal Barometer comes direct from its OEM, Jain Scientific Equipments Private Limited, which trades as ScienceLab and manufactures the instrument at its own licensed factory at Saha, Ambala, Haryana, India.

Schools, colleges, dealers and importers get quotations straight from the maker rather than through a trader, and questions about repeat orders or replacement parts go to the same source — just ask us. Our company profile has more background.

Related Laboratory Equipment

Build a complete weather-observation set with these instruments:

• Psychrometer (with Thermometer) — records air humidity and temperature next to the pressure reading.
• Aneroid Barometer — another aneroid model for comparison or extra stations.
• Fortin Barometer — a mercury barometer for comparing measurement principles.
• Indoor/Outdoor Thermometer — adds inside and outside temperatures to the daily log.

More instruments are listed in the Laboratory Equipment category.

Frequently Asked Questions

How does the Metal Barometer measure air pressure?
The Metal Barometer uses a sealed metal capsule that expands or contracts as atmospheric pressure changes. A mechanical linkage converts that small movement into pointer travel on the dial, so no mercury or other liquid is needed.

What size is the Metal Barometer?
The Metal Barometer has a base diameter of 90 mm and a field (dial) diameter of 57 mm. Other details, such as the scale range, are not listed here, so please ask us through the contact page before ordering.

How is a metal barometer different from a mercury barometer?
A Metal Barometer contains no liquid, so it is compact, portable and safe to handle in a classroom. A mercury instrument such as a Fortin barometer reads the height of a mercury column and is used mainly for fixed reference measurements.

Psychrometer (with Thermometer) (Product Code: SCI-095/022) is a humidity-measuring instrument used to determine air humidity and ambient temperature at the same time in school science and geography laboratories. Its temperature scale runs from -30 to 50 °C and its humidity scale from 0 to 100%, which makes it a practical choice among school lab instruments for weather studies. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is a Psychrometer Used For?

A psychrometer typically compares a dry-bulb reading with a wet-bulb reading taken from a thermometer whose bulb is kept moist. Evaporation cools the wet bulb, and the drier the air, the larger the difference between the two; that difference is converted into relative humidity. Students can use it to track daily humidity alongside temperature, compare indoor and outdoor air, or check conditions in a greenhouse or storeroom.

As educational lab equipment it links physics topics such as evaporation and latent heat with geography topics such as weather and climate. For steady readings, place the instrument in shade with free air movement, away from heaters and windows, use distilled water for any wet-bulb wick, and let the reading settle for a few minutes before recording it.

OEM Manufacturer

ScienceLab is the OEM of the Psychrometer (with Thermometer). Its legal company, Jain Scientific Equipments Private Limited, produces the instrument at its own licensed factory at Saha, Ambala, Haryana, India.

Single schools, colleges, dealers and importers all order from the manufacturer itself, so pricing, repeat supplies and questions about spare thermometers are handled without a middleman — ask us for what you need. Visit our company profile to learn more.

• Metal Barometer — adds air pressure to the humidity and temperature record.
• Digital Hygrometer - Thermometer — a digital cross-check for humidity readings.
• Indoor/Outdoor Thermometer — compares inside and outside temperatures.
• Wash Bottle LDPE with Narrow Mouth — handy for applying distilled water to a wet-bulb wick.

See more instruments in the Laboratory Equipment category.

Frequently Asked Questions

What does the Psychrometer (with Thermometer) measure?
The Psychrometer (with Thermometer) measures air humidity and, at the same time, the ambient temperature. Its temperature scale covers -30 to 50 °C and its humidity scale covers 0 to 100%, so both values can be recorded from one instrument.

How is relative humidity read from a psychrometer?
With a psychrometer, relative humidity is found from the difference between the dry-bulb and wet-bulb temperatures: the bigger the gap, the drier the air. The difference is then converted to a humidity percentage, usually with a psychrometric table.

Where should the Psychrometer (with Thermometer) be placed?
Place the Psychrometer (with Thermometer) in a shaded spot with gentle air movement, away from heaters, sunny windows and people crowding around it. Allow a few minutes for the reading to settle before noting the humidity and temperature.

Is a calibration certificate available for this psychrometer?

Calorimeter (Product Code: SCI-097/023) is a copper vessel used to measure heat exchange, such as specific heat capacity and heat of neutralisation, in school and college physics and chemistry laboratories. Students use it for method-of-mixtures calorimeter lab work, and the polished copper vessel comes with a fitted wooden/bakelite lid, a rubber stopper and a metal stirrer. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is a Calorimeter Used For?

In the classic method of mixtures, students weigh the empty vessel with its stirrer, add a known mass of water and record its temperature, then drop in a heated solid or warm water and stir until the reading stops changing. Because heat lost equals heat gained, the result gives the specific heat capacity of the sample. The rubber stopper in the lid is normally used to hold the thermometer steady while the metal stirrer keeps the temperature even.

Alongside other physics lab instruments it is used for latent heat of fusion of ice, and in chemistry practicals for heat of neutralisation. Copper warms up quickly and evenly, and its polished surface cuts heat loss by radiation; standing the vessel in an insulating jacket reduces losses further. Dry the vessel after every use to keep the polish bright.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited (CIN U29309HR2020PTC087597), the OEM that makes this copper calorimeter. Production takes place at the company's licensed factory at 449, HSIIDC Industrial Area, Saha, Ambala, Haryana (Factory Licence AMB-ONLINE-CHD-J-414).

Ordering from the factory itself suits schools equipping several benches, as well as dealers and importers who need consistent repeat supplies; for lids, stirrers or stoppers as spares, ask us. The company profile has further details.

Related Laboratory Equipment

• Calorimeter Lagging — an insulating jacket that reduces heat loss to the room.
• Laboratory Thermometers 0-200 deg C — for temperature readings through the stopper.
• Glass-Ceramic Heating Plate — heats water or samples before mixing.
• Calorimeter With Accessories — an alternative model supplied as a set.

Browse further apparatus under Laboratory Equipment.

Frequently Asked Questions

What is the Calorimeter made of?
The Calorimeter (SCI-097/023) has a copper vessel with a polished finish. It is fitted with a wooden/bakelite lid and comes with a rubber stopper and a metal stirrer, which together cover the basic needs of a method-of-mixtures experiment.

Is a thermometer included with the Calorimeter?
No thermometer is listed with the Calorimeter; the listed items are the copper vessel, the fitted wooden/bakelite lid, a rubber stopper and a metal stirrer. A laboratory thermometer can be ordered separately and held in the stopper during the experiment.

Why is the calorimeter vessel made of copper?
Copper conducts heat well, so the Calorimeter vessel quickly reaches the same temperature as its contents, and its specific heat capacity is well known, which makes the correction for the vessel simple. The polished surface also limits heat lost by radiation.

How can heat loss from the Calorimeter be reduced?
Keep the lid of the Calorimeter closed, stir steadily, take the final reading promptly and place the vessel inside insulating lagging. Starting with water slightly below room temperature and ending slightly above it also helps losses and gains balance out.

Laboratory Thermometers 0-200 deg C (Product Code: SCI-106/027) are graduated glass alcohol thermometers used to measure temperatures from 0 to 200 °C in school, college and general chemistry laboratories. Students and technicians use these everyday laboratory instruments for heating, boiling-point and calorimetry work, and the alcohol filling keeps mercury off the bench. They are made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Are 0-200 °C Laboratory Thermometers Used For?

A 0 to 200 °C range covers most bench tasks in a teaching laboratory: checking water baths and hot plates, finding the boiling point of water and many organic liquids, following the temperature of a reaction, reading vapour temperature during a simple distillation and recording start and end temperatures in calorimetry. As basic thermometry apparatus, they also let students plot heating and cooling curves.

For reliable readings, immerse the bulb to a steady depth, wait for the column to stop moving and read at eye level to avoid parallax. Never heat beyond the upper end of the scale, avoid moving a hot thermometer straight into cold liquid, and store the thermometers flat or in a case. Before each use, check that the liquid column is continuous.

OEM Manufacturer

Jain Scientific Equipments Private Limited, known by its trading name ScienceLab, is the OEM for these laboratory thermometers and manufactures them at its own licensed factory at Saha, Ambala, Haryana, India.

Thermometers are replaced often in student laboratories, and reordering straight from the maker lets you quote the same product code every term; schools, dealers and importers all buy factory-direct. Ask us about quantities, and read more on our company profile.

Frequently Asked Questions

What range do the Laboratory Thermometers 0-200 deg C cover?
The Laboratory Thermometers 0-200 deg C measure from 0 to 200 °C on a graduated glass stem. They are alcohol-filled and chemical resistant, which suits routine heating, boiling-point and calorimetry work in teaching laboratories.

Why choose an alcohol thermometer instead of a mercury one?
An alcohol laboratory thermometer contains no mercury, so a breakage does not create a mercury spill to clean up. That makes the Laboratory Thermometers 0-200 deg C a practical choice for student benches where glassware is handled often.

What should I do if the liquid column separates?
If the column in a Laboratory Thermometer 0-200 deg C separates, cooling the bulb gently and tapping the thermometer upright often rejoins it. Do not heat the thermometer to force the column together; if the gap remains, contact us for advice.

pH-Meter 50 deg C (Product Code: SCI-1308/028) is a pen-style digital pH meter used to measure the acidity or alkalinity of water and aqueous solutions in school, college and field testing. Students and laboratory staff use it for quick readings across a 0–14.0 pH range with 0.1 pH resolution, at operating temperatures from 0 to 50 °C. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is a Pen-Type pH Meter Used For?

A pen-type meter brings pH measurement out of the instrument room and onto the student bench. Typical uses include checking tap, pond or aquarium water, testing soil extracts, following acid–base reactions and comparing household solutions such as vinegar, soap and baking soda. Because the result appears as a number, students can record and graph readings instead of judging a colour change.

Regular pH meter calibration against standard buffer solutions keeps readings trustworthy. Rinse the electrode with distilled water between samples, blot it gently rather than wiping, keep the protective cap on during storage and allow hot samples to cool to 50 °C or below before measuring.

Supplier

Jain Scientific Equipments Private Limited, which trades as ScienceLab, supplies the pH-Meter 50 deg C to schools, colleges, laboratories, dealers and importers.

Adapters (Alunge) (Product Code: SCI-110/029) are clear glass adapters used to connect a condenser to the receiving flask in distillation set-ups in school and college chemistry laboratories. Students and laboratory assistants use them to guide distillate neatly into the receiver; each adapter is 150 mm long and made of fireproof glass pipe that is heat and chemical resistant. This chemistry lab glassware is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is an Alunge Adapter Used For?

In a simple distillation, an alunge (also spelled allonge) adapter fits on the lower end of the condenser and carries the condensed liquid down into the receiving flask. This reduces splashing and vapour loss at the outlet, and the clear glass lets students watch the drops of distillate as they form. The same adapter is useful in fractional and steam distillation practicals wherever a condenser outlet must be led into a receiver.

When assembling distillation apparatus, support the condenser with a clamp so that the adapter carries no load, and join the parts without forcing them. Although the glass is heat resistant, let the adapter cool before washing it and avoid sudden temperature changes; rinse it after each run so that residues do not build up.

What to Specify When Ordering

• The number of adapters, including spares for breakage in student classes.
• The condenser and flask you will use it with, so we can confirm the connection suits them (only the 150 mm length is listed here).
• Whether the rest of a distillation set, such as the condenser and distillation pot, should be quoted together.

OEM Manufacturer

ScienceLab offers these adapters as their original manufacturer, not as a reseller. Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM and produces them at its own licensed factory at Saha, Ambala, Haryana, India.

Glass parts break from time to time, and buying from the maker keeps replacements simple: send the product code and the manufacturer quotes directly. Schools, colleges, dealers and importers are all supplied factory-direct — see our company profile.
