Wheatstone Bridge Four Gap (Product Code: SLE/PHY/75) is a metre-scale slide-wire bridge used to measure unknown resistances and compare resistors in school and college physics practicals. Broad, heavily plated brass strips with four gaps sit on a polished hardwood base, and 24 SWG constantan wire is stretched along the top of a metre scale marked in mm and cm. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Four-Gap Wheatstone Bridge Used For?

With a known resistance in one gap and the unknown in another, a galvanometer connected between the bridge and the jockey shows zero deflection at the balance point, and the two lengths of wire on either side give the ratio of the resistances. The extra gaps allow more elaborate set-ups, such as the Carey Foster arrangement for comparing two nearly equal resistances, in which the resistors are interchanged to cancel end errors.

Typical practicals include finding the resistance and specific resistance of a wire and checking the laws of resistors in series and parallel, which makes this a practical Wheatstone bridge experiment kit once a cell, key, galvanometer and resistance box are added. Tighten the terminals firmly, tap the jockey rather than sliding it along the wire, and repeat each balance with the resistors swapped for a more reliable mean.

OEM Manufacturer

Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the OEM of this four-gap bridge and produces it at its own licensed factory at Saha, Ambala, Haryana, India. ScienceLab is the trading name of Jain Scientific Equipments Private Limited (CIN U29309HR2020PTC087597), and the factory at 449, HSIIDC Industrial Area, Saha operates under Factory Licence AMB-ONLINE-CHD-J-414.

Trinocular Microscope, LED (Product Code: SLE/M/14) is a compound light microscope with a camera port, used to examine stained slides at 40x to 1000x in college and school biology laboratories. Its 30° trinocular head rotates through 360°, so an instructor can view a slide while a camera on the third tube shares the same field with the class. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as part of its compound microscope range.

Specifications

What Is the Trinocular LED Microscope Used For?

In teaching labs the Trinocular Microscope, LED is typically used for histology, botany and microbiology practicals where the whole group needs to see the same cell or tissue feature. The instructor focuses a prepared slide through the eyepieces, and a camera fitted to the third tube relays that image to a screen for discussion or for practical records. The 100x oil-immersion objective brings bacteria, blood cells and fine cell detail into view at 1000x total magnification.

Good practice: start every slide at 4x with the coaxial coarse knob, centre the specimen with the X-Y stage controls, then step up through 10x and 40x using the fine knob only. Keep the Abbe condenser raised for high power, turn the LED down at low power to avoid glare, and wipe immersion oil off the 100x lens after each session. In school biology lab equipment in India, one trinocular model like this often sits at the demonstration bench beside several monocular student microscopes.

What to Specify When Ordering

Knife Switch Double Pole (Product Code: SLE/PHY/76) is a double-pole, double-throw (DPDT) knife switch on a plastic base, used to open, close and change over circuits in school electricity experiments. Its poles and blades are made of brass for good electrical connections, and the lever position shows students at a glance whether a circuit is made or broken. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Key Details

What Is the Double Pole Knife Switch Used For?

A DPDT switch moves two separate contacts with one lever, so it can switch two circuits together or change a single load between two supplies. Its classic school use is as a reversing switch: with the outer terminals cross-connected, throwing the blades one way or the other reverses the current through a motor, coil or galvanometer. That makes it a handy part of any AC DC circuits experiment kit on the physics bench.

Teachers also like knife switches because the open blade is visible from the back of the room, unlike a sealed switch. Use it with cells or low-voltage supplies only, since the brass parts are exposed; close the blades firmly into their clips, and keep the brass clean so contact stays good.

What to Specify When Ordering

• Quantity of double-pole switches needed
• Whether you also need single-pole knife switches for simpler circuits
• Any current or voltage requirement, so we can confirm suitability

Its 45° head and its round 90 mm stage both rotate through 360°, which makes it easy to share across a bench. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, to schools looking for a monocular microscope in India and abroad.

Specifications

What Is the Monocular LED Microscope Used For?

As a compound microscope, the Digital Monocular Microscope, LED is built for slide-mounted specimens: examining pre-mounted slides, making temporary mounts of onion peel, cheek cells or pond water, and looking at them under high power. Compound optics give a narrow field and a short working distance, so the specimen must be thin enough for light from below to pass through it.

Thick, unmounted material such as insects, plants, rocks and fossils, or micro-dissection work, calls for a stereo microscope instead, which offers low power, a wide field and a long working distance. Many schools keep a few of each. With this model, begin at 4x with the LED turned low, rotate the round stage to line up the specimen, and raise the intensity as you move to 40x.

What to Specify When Ordering

• The digital output you expect (camera, screen or software), since none is listed in the current specification.
• Number of microscopes needed for each class or lab.
• Slides, cover slips and slide boxes to add to the same consignment.

Student Microscope with Fixed Condenser (Product Code: SLE/M/17) is a mirror-illuminated compound microscope used to teach slide observation from 50x to 675x in school and junior-college biology practicals. Its fixed Abbe-type condenser with iris diaphragm, 10x and 15x eyepieces and all-metal stand that inclines up to 90° suit everyday class use, and mirror lighting needs no mains point at the bench. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as school biology lab equipment.

Specifications

What Is the Student Microscope with Fixed Condenser Used For?

This is the everyday instrument for class practicals on onion epidermis, cheek cells, leaf and stem sections and bought-in prepared slides. Students find the specimen with the 10x objective and 10x eyepiece, then swing in the 40/45x objective and change to the 15x eyepiece for detail up to 675x. Because the optics are parfocal, the image stays nearly in focus when the nosepiece turns, so only the fine knob is needed.

Lighting comes from the gimbal-mounted plano-concave mirror, which can be angled towards a window or a separate lamp; the flat face usually works best with the condenser, while the concave face helps when light is weak. Close the iris diaphragm a little to add contrast to unstained mounts, and open it for stained specimens at high power. Tilting the arm back makes long sessions more comfortable for seated students.

What to Specify When Ordering

• Number of microscopes for each practical batch.
• Fixed condenser (this model, SLE/M/17) or the movable-condenser version (SLE/M/18).
• Whether you need a separate light source, since the listed illumination is a mirror.
• Slides, cover glasses and slide storage to include in the same consignment.

Supplier

ScienceLab, the trading name of Jain Scientific Equipments Private Limited in Ambala, Haryana, supplies this fixed-condenser student microscope to schools, state and private education buyers, dealers and importers.
