Calorimeter, Copper (Product Code: SLE/PHY/144) is a plain copper calorimeter vessel used to contain water or other liquids in specific-heat, latent-heat and cooling experiments in school and college physics laboratories. At 100 mm long and 65 mm in diameter, with parallel sides and a rolled rim, it leaves room for a thermometer, a stirrer and a solid sample; no stirrer is included. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is a Copper Calorimeter Used For?

Copper conducts heat very well, so the vessel and its contents settle to the same temperature quickly, which keeps readings consistent. Common practicals include the specific heat capacity of a solid by the method of mixtures, the latent heat of vaporisation of water by condensing steam into the cup, and Newton's law of cooling, where the copper cup is filled with hot water and its temperature is logged as it cools.

It is a standard piece of thermometry apparatus in India's physics labs. Keep the outside surface clean and bright to limit heat lost by radiation, weigh the empty vessel before each experiment, and dry it straight after use to slow tarnishing. A separate stirrer is needed, since the cup is supplied bare.

What to Specify When Ordering

• The quantity of copper calorimeters per lab or per student pair.
• Stirrers and thermometers to go with them, as none are included.
• Any lagging or outer container for insulated work.
• Whether aluminium calorimeters are also needed for comparison.

Capacitance Substitution Box (Product Code: SLE/PHY/145) is a switch-selected capacitor box used to insert a known capacitance into a circuit for RC timing, filter and AC reactance experiments in physics and electronics labs. A rotary selector switch chooses preferred values from 100 pF to 1 µF, each within ±5% and rated at 63 V, through two 4 mm safety sockets on a 75 x 100 x 40 mm ABS case. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is a Capacitance Substitution Box Used For?

Instead of soldering individual capacitors, students turn the selector to swap values and see at once how capacitance changes the time constant of an RC circuit, the cut-off point of a simple filter, or the reactance of a capacitor in an AC circuit driven by a signal generator and viewed on an oscilloscope. That flexibility makes it a useful part of any AC DC circuits experiment kit at college level.

Because the values run from picofarads to one microfarad, the box suits signal-frequency work; slow charge-and-discharge demonstrations read on a meter usually use larger capacitors. Keep the applied voltage below the 63 V rating, switch the supply off before changing value, and connect with shrouded 4 mm leads.

What to Specify When Ordering

• The number of capacitance substitution boxes needed.
• Whether a resistance substitution box should be quoted for RC work.
• Whether a signal generator and oscilloscope are also required.
• Connecting leads with 4 mm plugs for the safety sockets.

Supplier

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, which supplies this capacitance substitution box from Ambala, Haryana, for physics and electronics laboratories. Institutional and tender buyers who need vendor registration details can use GSTIN 06AAECJ8618A1ZT and LEI 3358004HRD1JIVXKYX49. Background on the company is on the ScienceLab profile page.

Frequently Asked Questions

What capacitance values does the Capacitance Substitution Box provide?
The Capacitance Substitution Box selects 100 pF, 220 pF, 470 pF, 2.2 nF, 4.7 nF, 10 nF, 22 nF, 47 nF, 100 nF, 220 nF, 470 nF and 1 µF, a set of preferred values chosen with its rotary switch.

What are the accuracy and voltage rating of the Capacitance Substitution Box?
Every value in the Capacitance Substitution Box has an accuracy of ±5% and a rating of 63 V. Keep circuit voltages below that rating, and allow for the ±5% tolerance when comparing measured time constants with calculated ones.

How is the Capacitance Substitution Box connected to a circuit?
The Capacitance Substitution Box connects through two 4 mm safety sockets on its ABS case, so standard 4 mm plug leads fit directly. The selected capacitor appears between the two sockets as soon as the rotary switch is turned.

Can the Capacitance Substitution Box be used for RC time-constant experiments?
Yes, the Capacitance Substitution Box can be combined with a resistor or resistance box for RC experiments. With its picofarad-to-microfarad values the time constants are short, so a signal generator and oscilloscope are the usual way to observe them.

Conductive Paper (Product Code: SLE/PHY/147) is a resistive paper used to map electric fields by the equipotential points method in school and college physics labs. It comes as sheets of 38 cm x 53 cm, packed ten to a pack, and can also be cut into strips to make simple home-made resistors for electricity investigations. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is Conductive Paper Used For?

To plot a field, two electrodes are fixed on the sheet and connected to a low-voltage DC supply. A probe linked to a voltmeter or centre-zero galvanometer is moved across the paper to find points at the same potential; students mark them, join them into equipotential lines, and then sketch field lines at right angles. Changing the electrode shapes, such as two points, two parallel bars, or a point and a ring, shows how the field pattern follows the geometry.

Cut into strips, the same paper becomes a cheap resistor whose resistance rises with length and falls with width, which makes a neat investigation for physics lab equipment in India at secondary level. Store the sheets flat and dry, avoid folding or creasing them, and handle them by the edges to keep the surface even.

What to Specify When Ordering

• The number of packs (each pack holds 10 sheets of 38 cm x 53 cm).
• Whether a probe, galvanometer or voltmeter is needed for field plotting.
• Whether a low-voltage DC power supply should be quoted as well.

Supplier

Jain Scientific Equipments Private Limited, trading as ScienceLab, supplies conductive paper from Ambala, Haryana, as a consumable for electrostatics and electricity practicals. Schools, colleges, dealers and importers in India and international markets can order it together with the meters and supplies used in field-plotting work. Company information is on the ScienceLab profile page.

Related Physics Lab Equipment

Apparatus used with conductive paper:

• Galvanometer, Centre Zero Universal Meter — null indicator for locating equipotential points.
• Jockey with Insulated Handle (Single) — insulated probe for touching points on the sheet.
• Power Supply, Stepped — low-voltage source for the electrodes.
• Standard Digital Multimeter — reads potential at each point or the resistance of a strip.
• Conductive Putty — another shape-it-yourself conductor for resistance experiments.

See more in the Physics Lab Equipment category.

Frequently Asked Questions

What size is Conductive Paper and how many sheets are in a pack?
Conductive Paper comes in sheets of 38 cm x 53 cm, with 10 sheets in each pack. One sheet can be cut into smaller pieces so several student groups can plot fields or make strip resistors at the same time.

How is Conductive Paper used to plot electric fields?
On Conductive Paper, two electrodes are connected to a DC supply and a probe finds points of equal potential using a meter or galvanometer. Joining those points gives equipotential lines, and field lines are drawn at right angles to them.

Can Conductive Paper be used to make resistors?
Yes, Conductive Paper can be cut into strips to produce home-made resistors. Students can compare strips of different lengths and widths to see how resistance depends on the shape of a conductor, using a multimeter to take the readings.

What else is needed with Conductive Paper?
To use Conductive Paper for field plotting you need electrodes, a low-voltage DC power supply, connecting leads, a probe and a voltmeter or centre-zero galvanometer. These are ordered separately and can be quoted together with the paper.

How should Conductive Paper be stored?
Store Conductive Paper flat in a dry cupboard, away from damp and direct sunlight. Avoid folding or creasing the sheets and handle them by the edges, because a damaged surface can distort the equipotential pattern during an experiment.

Who supplies Conductive Paper?
Conductive Paper is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. Schools, colleges, dealers and importers can order it in packs of 10 sheets alongside the meters and power supplies used with it.

What should a Conductive Paper quotation request include?
A Conductive Paper quotation request should give the product code SLE/PHY/147, the number of packs, any meters, probes or power supplies you want added, and the delivery address in India or abroad.

Conductivity of Metal Apparatus (Product Code: SLE/H/28) turns a comparison of four metals into a timed race. Strips of copper, brass, steel and aluminium are mounted on a wooden ring and meet in the centre; when the centre is heated gently, wax placed in a hollow at the far end of each strip melts, and the difference in the time each cup of wax takes to melt shows how fast heat travels through each metal. It is a favourite for middle- and secondary-school heat lessons, and it is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a school laboratory equipment manufacturer supplying India and international markets.

Key Details

Typical Use

Students put a small, equal amount of wax into the hollow at the end of each strip, then place a gentle flame under the centre point and start timing. Because all four strips draw heat from the same shared centre, the only thing that differs is the metal. As each cup of wax melts, students log the time, and the finishing order gives a direct ranking of conduction rates. Asking the class to predict the order first, then explaining the result in terms of how readily each metal passes on heat, makes the lesson stick.

For fair results, use the same amount of wax in every hollow, keep the flame small and centred so it does not reach the wooden ring, and let the apparatus cool before resetting the wax. With a stop clock and a data table it becomes a neat, quantitative piece of physics lab equipment for school practicals, and its open layout lets a whole group watch the wax melt.

Manufacturer

ScienceLab products, including this conductivity ring, are manufactured by Jain Scientific Equipments Private Limited of Ambala, Haryana, for schools, colleges and distributors. Our company profile gives an overview of the business.

Related Laboratory Equipment

Everything else a timed conduction practical usually needs:

• Stop Clock — for timing how long each cup of wax takes to melt
• Wax — for filling the hollows at the end of each strip
• Micro Burner — a small, controllable flame for gentle heating at the centre
• Conductivity Apparatus — a six-metal rod version for a wider comparison

Find more thermal teaching aids in our Heat range.

Frequently Asked Questions

Which metals does the ring compare?
Copper, brass, steel and aluminium, each as a strip running to the centre.

How are the results measured?
By the difference in time taken for the wax in each strip's hollow to melt once the centre is heated.

Is wax supplied?
Wax is not listed among the included items; it can be ordered separately from our range.

What heat source should be used?
A small, gentle flame such as a micro burner or spirit lamp placed under the centre. A heat source is not listed as supplied.

How does this differ from the Conductivity Apparatus (SLE/H/19)?
This model uses four strips on a wooden ring and times melting wax cups; the SLE/H/19 apparatus holds six metal rods in a sheet-metal body.

Can you supply class sets or export orders?
Yes. We supply schools and distributors across India and international markets; state the quantity and destination, and warranty terms will be confirmed in the quotation.

Convection in Air Apparatus (Product Code: SLE/PHY/148) is a two-chimney box used to make convection currents in air visible, with smoke drawn down one chimney and up the other over a candle, in school science labs. It is a metal box of 220 x 100 x 165 mm with a sliding glass front, two detachable glass chimneys and a candle holder fixed beneath the left chimney. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Convection in Air Apparatus Used For?

A candle is lit in the holder under the left chimney and the glass front is slid shut. When smouldering paper or an incense stick is held over the right chimney, the smoke is pulled down into the box, drifts across to the flame and rises out through the left chimney. Students see that warm air rises and cooler air flows in to replace it, which is the basis of convection currents.

This simple demonstration model for the physics lab links directly to sea and land breezes, room ventilation and why chimneys draw. Use a short candle so the flame sits well below the chimney, keep the glass front closed during the demonstration, and let the chimneys cool before lifting them off to wipe away soot.

What to Specify When Ordering

• The number of Convection in Air Apparatus units needed.
• Candles, since none are included with the apparatus.
• Whether spare glass chimneys should be quoted with the order.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab (CIN U29309HR2020PTC087597), is the OEM of the Convection in Air Apparatus.

Crushing Can (Product Code: SLE/PHY/150) is a light-walled tin plate can with an air-tight screw cap used to demonstrate the force exerted by atmospheric pressure in school and college physics laboratories. Teachers rely on it for a memorable class demonstration in which the 75 mm diameter can collapses once the air inside has been driven out by steam. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, as part of its physics lab equipment for schools.

Specifications

What Is the Crushing Can Used For?

The crushing can experiment shows students that the air around them presses on every surface with a surprisingly large force. A little water is heated in the open can until steam pushes most of the air out, the heat is removed and the cap is screwed on tight. As the steam cools and condenses, the pressure inside falls far below the pressure outside, and the atmosphere crumples the thin walls, often with an audible crack. Pouring cold water over the sealed can makes the collapse faster and more dramatic.

For safety, never heat the can with the cap in place, and handle the hot can with tongs or heat-resistant gloves. Only a shallow layer of water is needed, which keeps heating time short. The demonstration fits naturally into lessons on air pressure, gas laws and weather, and it is a practical addition to any physics lab equipment list for schools in India and abroad.

What to Specify When Ordering

• Number of cans — the light-walled can is designed to deform, so plan one per demonstration or group.
• Confirmation that the 260 x 75 mm size suits your burner and tripod set-up.
• Any heating accessories you also need, such as a burner, tripod or gauze.
• Delivery location, within India or overseas, so the quotation can include dispatch details.

OEM Manufacturer

Jain Scientific Equipments Private Limited trades as ScienceLab and is the OEM (original equipment manufacturer) of the Crushing Can. The can is produced at the company's own licensed factory at Saha, Ambala, Haryana, India, so schools, colleges, laboratory dealers and importers deal directly with the maker instead of a trading intermediary. Replacement cans for future terms can be ordered from the same source — ask us about current availability. You can read more about the company on our company profile.

Browse the full range of Physics Lab Equipment for other pressure, heat and mechanics apparatus.

Frequently Asked Questions

What size is the Crushing Can?
The Crushing Can measures 260 x 75 mm, with a 75 mm diameter body made from light-walled tin plate and closed by an air-tight screw cap. The thin walls are what allow atmospheric pressure to crush it visibly during a class demonstration.

How does the Crushing Can show atmospheric pressure?
The Crushing Can shows atmospheric pressure by replacing the air inside with steam. Once the cap is sealed and the steam condenses, the pressure inside drops sharply, so the unbalanced pressure of the outside air pushes the thin tin plate walls inward until the can collapses.

Can the Crushing Can be heated with the cap closed?
No. The Crushing Can must always be heated with the screw cap removed so that steam can escape freely. Fit the air-tight cap only after the heat source has been taken away, then let the can cool or pour cold water over it.

Can one Crushing Can be used for several demonstrations?
A Crushing Can is light-walled and meant to deform, so a collapsed can generally cannot be returned to its original shape. Most teachers treat it as a demonstration consumable and order enough cans for the number of classes or groups they plan to teach.

Who manufactures the Crushing Can?
The Crushing Can is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own factory at Saha, Ambala, Haryana, India. Buyers receive quotations and repeat supplies directly from the manufacturer rather than through a trader.

What does a quotation for the Crushing Can need?
A quotation for the Crushing Can needs the product code SLE/PHY/150, the number of cans, any related items such as burners or tripods, and the delivery location. Send these details through our contact page and we will reply with a quotation.
