Plotting Compass, Single Glass Face (Product Code: SLE/PHY/267) is a small magnetic compass in an aluminium case, used to trace magnetic field lines around magnets and current-carrying wires in school physics practicals. Teachers order it in packs of 10 for group work; each compass is 16mm in diameter, glass-faced on one side, with a dial marked with the cardinal and ordinal points. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, and suits any magnetism experiment kit.

Specifications

What Is a Plotting Compass Used For?

To map a field, place a bar magnet on a sheet of paper and set the compass near one pole. Mark a dot at each end of the needle, move the compass so its tail sits on the front dot, and repeat; joining the dots traces one field line, and starting from several points builds up the whole pattern. The same method locates neutral points between two magnets and shows the circular field around a straight current-carrying wire or the field of a coil. Because each compass is only 16mm across, plotted points sit close together and the lines come out smooth.

Before use, check that every needle settles in the same direction when the compasses are laid well away from magnets. Store the compasses in their pack, away from strong magnets that could weaken or reverse a needle, and handle them by the aluminium case to protect the glass face. Pair them with a bar magnet for school practicals, and with a current-carrying frame or coil for electromagnetism lessons.

What to Specify When Ordering

• The number of packs of 10 you need for your student groups
• Whether you want this glass-faced style or the Compass Plotting (Clear) version

Polarizing Filter Stress Demonstrator (Product Code: SLE/PHY/268) is a large-scale optics demonstrator that uses polarising filters to reveal stress patterns in clear plastic pieces, used in physics and engineering classrooms. Its 5 inch polarising sheets are mounted on a graduated frame on a wooden stand, and it is supplied with clear acrylic pieces of different shapes to squeeze between the filters. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Polarizing Filter Stress Demonstrator Used For?

The demonstrator introduces photoelasticity. Clear acrylic becomes birefringent when it is stressed: polarised light passing through a loaded piece has its polarisation altered by different amounts wherever the stress differs, and viewing through the second filter turns those differences into coloured bands. The bands crowd together near corners, holes and the points where force is applied, so students can see where a shape is most highly stressed — the reason engineers round off corners in brackets and beams. It doubles as a physics demonstration kit for polarisation itself.

Stand the demonstrator in front of a bright, even light source such as a window or a lamp, and squeeze each acrylic piece slowly and steadily so the class sees the pattern grow; release it and the colours fade. Compare the different shapes one after another. Clean the acrylic and the polarising sheets with a soft cloth only, since scratches show up as marks in the pattern.

OEM Manufacturer

ScienceLab, the trading name of Jain Scientific Equipments Private Limited, is the OEM (original equipment manufacturer) of the Polarizing Filter Stress Demonstrator and builds it at its own licensed factory at Saha, Ambala, Haryana, India. Schools, colleges, institutions, dealers and importers receive it factory-direct, with quotations and any later requests for replacement acrylic pieces handled by the maker — ask us.

Frequently Asked Questions

What does the Polarizing Filter Stress Demonstrator show?
The Polarizing Filter Stress Demonstrator shows stress patterns in clear plastic. When an acrylic piece is squeezed between its polarising filters, coloured bands appear that reveal where the stress is concentrated, making invisible internal forces visible to a whole class.

What comes with the Polarizing Filter Stress Demonstrator?
The Polarizing Filter Stress Demonstrator comes with 5 inch polarising sheets mounted on a graduated frame, placed on a wooden stand, and is supplied with clear acrylic pieces of different shapes so that different stress patterns can be demonstrated.

Why do coloured patterns appear in the Polarizing Filter Stress Demonstrator?
Coloured patterns appear in the Polarizing Filter Stress Demonstrator because stressed acrylic changes the polarisation of light passing through it. The amount of change depends on the stress and on the wavelength, so the second filter shows the stress as bands of colour.

Is the Polarizing Filter Stress Demonstrator suitable for a whole class?
Yes, the Polarizing Filter Stress Demonstrator is a large-scale unit with 5 inch polarising sheets, designed for demonstration at the front of a class. Place it against a bright background so students across the room can watch the patterns change.

Who manufactures the Polarizing Filter Stress Demonstrator?
The Polarizing Filter Stress Demonstrator is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory in Saha, Ambala, Haryana, India, and supplied direct to buyers in India and international markets.

Polaroid Slides (Product Code: SLE/PHY/269) are polarising sheets mounted in square plastic slides, used to demonstrate the polarisation of light in school and college optics lessons. Teachers use them in pairs — one as the polariser and one as the analyser — so students can watch light dim and almost disappear as one slide is turned against the other. They are supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, for any optics experiment kit at school level.

Key Details

What Are Polaroid Slides Used For?

Hold one slide up to a lamp and the light passing through is dimmed but still visible. Add a second slide in front and rotate it: the brightness rises and falls, and when the two are at right angles very little light gets through. This simple observation shows that light is a transverse wave and gives a qualitative introduction to Malus’s law before any measurements are taken.

The slides also let students explore polarisation in everyday life: look through one at glare reflected from water or a glass surface at an angle, at an LCD screen as the slide is turned, or at clear plastic objects such as rulers placed between two slides to reveal stress patterns. Hold the slides by their plastic mounts, keep them away from heat and solvents, and wipe the sheets gently with a soft, dry cloth.

Supplier

These Polaroid Slides are supplied by Jain Scientific Equipments Private Limited, which trades as ScienceLab and is based in Ambala, Haryana. Schools, colleges, teacher-training institutes and dealers in India and international markets can source them together with light sources, benches and other optics items.

Frequently Asked Questions

What are Polaroid Slides used for?
Polaroid Slides are used to demonstrate the polarisation of light. Each slide is a polarising sheet mounted in a square plastic frame; looking through two slides while turning one shows the light fading and returning, proving that light behaves as a transverse wave.

How many Polaroid Slides are needed for a demonstration?
A polarisation demonstration needs at least two Polaroid Slides, one acting as polariser and one as analyser. Tell us how many demonstration sets or student groups you are equipping, and we will confirm the pack quantity available.

What happens when two Polaroid Slides are crossed?
When two Polaroid Slides are crossed, with one turned at right angles to the other, very little light passes through and the view goes dark. Turning one slide back gradually restores the brightness, a clear demonstration of polarisation.

How should Polaroid Slides be cleaned and stored?
Clean Polaroid Slides with a soft, dry cloth, holding them by the plastic mount so the polarising sheet is not scratched or marked. Store them flat in a box away from heat, sunlight and solvents between lessons.

Who supplies Polaroid Slides?
Polaroid Slides are supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. The company handles orders from schools, colleges and dealers in India and international markets, often alongside other optics apparatus.

Potentiometer Module (Product Code: SLE/PHY/271) is a rotary linear potentiometer mounted on a channel box, used as a variable resistor or voltage divider in student electricity practicals. This listing is the 100 Ω value, with connections made to 4 mm sockets and a fast-blow fuse that protects the module when students connect it wrongly. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the Potentiometer Module Used For?

A potentiometer has a resistive track and a moving wiper. Connected across a supply, it works as a voltage divider that gives a smoothly adjustable output for lamp-brightness, motor-speed or diode-characteristic experiments; used with one end of the track and the wiper only, it becomes a simple variable resistor for setting the current in a series circuit. That flexibility makes the module a useful part of an Ohm law experiment kit.

The linear track means equal turns of the knob give roughly equal changes in resistance, which helps students plot tidy graphs. The 100 Ω value suits low-resistance circuits in which a larger current must flow; for finer control at lower currents, compare the 1 kΩ module. If the module stops responding after a wiring mistake, the fast-blow fuse is the first thing to check.

What to Specify When Ordering

• Resistance value: this listing is 100 Ω; the 1 kΩ Potentiometer Module is a separate item.
• Number of modules per bench or student group.
• 4 mm leads, meters or a power supply, if they should be quoted together.

Supplier

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, which supplies the Potentiometer Module from Ambala, Haryana, India. The company sources this channel-box module with the rest of its electricity apparatus and quotes it to schools, colleges, dealers and importers in India and international markets. Follow-up orders for extra modules or a different resistance value can be requested from us directly. Read more on the ScienceLab profile page.

Related Physics Lab Equipment

Items that are wired up with the potentiometer module:

• Potentiometer Module, 1 Kohm — the higher-resistance version for finer current control.
• Stackable Leads — plug leads for the module’s 4 mm sockets.
• Power Supply, Stepped — a low-voltage source for voltage-divider circuits.
• Ammeter Voltmeter — reads the current and voltage the potentiometer sets.
• Standard Digital Multimeter — checks resistance between the terminals.

See the complete Physics Lab Equipment range for more circuit apparatus.

Frequently Asked Questions

What resistance value is the Potentiometer Module?
The Potentiometer Module listed here has a value of 100 Ω. The original listing notes that a choice of values is available, and a 1 kΩ Potentiometer Module is listed separately, so state the value you need when you ask for a quotation.

How is the Potentiometer Module connected into a circuit?
The Potentiometer Module is connected through 4 mm sockets on its channel box, so standard 4 mm plug leads push straight in. Students can add the potentiometer to a bench circuit quickly and remove it again cleanly at the end of the practical.

What protects the Potentiometer Module from wrong connections?
The Potentiometer Module has a fast-blow fuse that protects it against wrong connections by students. If a short circuit or excessive current occurs, the fuse opens the circuit quickly, helping to protect the potentiometer during a busy practical class.

Is the Potentiometer Module linear or logarithmic?
The Potentiometer Module uses a rotary linear potentiometer. On a linear track, resistance changes in proportion to how far the knob is turned, which makes readings easier to predict and graph than with a logarithmic, audio-taper potentiometer.

What current can the Potentiometer Module carry?
A power or current rating for the Potentiometer Module is not stated in this listing. Before using it in higher-current circuits, send your circuit details through our contact page and we will advise whether the 100 Ω module is suitable.

Who supplies the Potentiometer Module?
The Potentiometer Module is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab) from Ambala, Haryana, India. The company sources the module and quotes it for schools, colleges, dealers and importers, together with leads, meters and power supplies where needed.

Power Supply Variable (Product Code: SLE/PHY/272) is a continuously variable AC/DC power supply unit for lab demonstrations and advanced-level student experiments in college and senior school physics. A rotary knob sets the output anywhere from 0 to 25 V at a combined current of up to 8.5 A, and the voltage is shown on a bright green 12.5 mm LED display. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the Variable Power Supply Used For?

Because the voltage can be wound up smoothly from zero, the unit suits experiments in which a quantity must change in small, even steps: current-voltage graphs for resistors, lamps and diodes, the heating effect of a current, or electromagnets and coils run at a controlled level. The combined 8.5 A rating leaves headroom for low-resistance loads such as heating elements, and the AC or DC output lets one unit serve both rectifier and transformer demonstrations.

Start each experiment with the knob at zero and raise the voltage while watching the display. If the protection trips, clear the fault and reset the unit rather than switching it on and off repeatedly; the microprocessor trip is designed to tell a brief surge, such as a cold lamp filament switching on, from a genuine short circuit. The fanless design also keeps the room quiet during a demonstration.

What to Specify When Ordering

• Number of units: for example one per demonstration bench or per student group in advanced-level practicals.
• Meters, leads or loads to be quoted with the power supply.
• The mains supply at your site, so we can confirm the unit matches it before dispatch.

Supplier

Jain Scientific Equipments Private Limited, trading as ScienceLab, supplies the Power Supply Variable from Ambala, Haryana, India. The company sources this bench power supply for its physics range and quotes it to colleges, schools, training institutes, dealers and importers in India and international markets.

Power Supply, Smoothed (Product Code: SLE/PHY/273) is a stepped low-voltage bench supply with a specially smoothed output, used to power electronics circuits in school and college laboratories. It delivers 2 to 12 V AC or DC in 6 steps at 5 A from a 230 V AC, 50 Hz mains input, and it is the smoothed version of the Power Supply, Stepped. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the Smoothed Power Supply Used For?

Transistors, integrated circuits, LEDs and logic gates behave best on a steady DC voltage. A plain rectified supply carries ripple that can make an amplifier hum, upset a timer circuit or make meter readings drift, so this unit adds smoothing to the stepped design. That makes it a practical low-voltage source for electronics practicals such as transistor characteristics, rectifier circuits and simple amplifier work.

Choose the lowest step that will run the circuit, switch off before moving to a different step, and keep the total load within the 5 A rating. For general electricity work with lamps and motors, where ripple does not matter, the standard stepped supply is an alternative, so many laboratories keep both on the shelf.

What to Specify When Ordering

• Smoothed output (this item) or the standard Power Supply, Stepped.
• Number of units per bench or student group.
• Confirmation that your mains matches the 230 V AC, 50 Hz input.
• Leads, meters or components to be quoted with it.

Prism – Acrylic, Set of 7 (Product Code: SLE/PHY/274) is a set of seven polished acrylic optical blocks used to study reflection, refraction and total internal reflection with a ray box in school and college optics lessons. Every block is 25 mm thick with all faces fully polished, and the shapes cover bi-convex, bi-concave, rectangular, semi-circular and three triangular prisms. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Acrylic Prism Set Used For?

Laid flat on paper in the path of a ray box beam, each block demonstrates a different part of the optics syllabus. The rectangular block shows lateral displacement and lets students work out refractive index from the angles of incidence and refraction; the semi-circular block is the standard shape for finding the critical angle and showing total internal reflection; and the bi-convex and bi-concave blocks make parallel rays converge or diverge like thin lenses drawn in two dimensions.

The 60° triangle disperses white light into a spectrum, while the two right-angled triangles show how a prism can turn a ray through a right angle or send it back the way it came by total internal reflection, the principle behind periscopes and binoculars. As a compact optics experiment kit for school benches, the set rewards careful handling: store the blocks so they do not rub together, and clean them with a soft cloth rather than solvents, which can craze acrylic.

What to Specify When Ordering

• Number of sets, usually one per student group for ray-optics practicals.
• Ray boxes and slit plates to be quoted with the blocks.
• Whether glass prisms or a glass rectangular block are also needed for comparison.
