Stereoscopic Dissection Microscopes (Product Code: SLE/M/32) are compact binocular microscopes used to magnify specimens at 20x during dissection practicals in school and college biology labs. A fixed 2x objective works with locked-in paired 10x wide-field eyepieces, and the unit packs into a wooden box. They are supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as practical school biology lab equipment in India and abroad.

Specifications

What Is the Stereoscopic Dissection Microscope Used For?

During a dissection, students need a steady, upright, three-dimensional view of small structures such as the mouthparts of a cockroach, the nerve cord of an earthworm or the ovary of a flower. This microscope gives that view at a fixed 20x, with up to 5 in of working distance so needles and forceps can move freely under the objective.

Set the height within its 8½ in to 12½ in range to suit the specimen, place small material on the stage plug and hold it with the clips, then bring it into focus with the rack and pinion. Students with unequal eyesight can use the diopter adjustment on one eyepiece. After class, the microscope returns to its wooden box, which keeps dust off the optics between sessions.

What to Specify When Ordering

• Standard version or the version with pillar stand
• Number of microscopes, usually one per dissection group
• Any dissection trays or depression slides to add to the order

Frequently Asked Questions

What magnification do the Stereoscopic Dissection Microscopes give?
The Stereoscopic Dissection Microscopes give a fixed 20x magnification from a 2x objective and locked-in paired 10x wide-field eyepieces. This low, constant power keeps a wide field of view and plenty of depth, which is what students need while dissecting.

How much working space is there under the objective?
The Stereoscopic Dissection Microscopes offer a working distance of 1½ in to 5 in, and the overall height adjusts from about 8½ in to 12½ in. That space lets students use needles, forceps and scalpels on the specimen while viewing it.

How are the Stereoscopic Dissection Microscopes focused?
The Stereoscopic Dissection Microscopes are focused with a rack-and-pinion mechanism. Because the eyepieces are locked in place, students only turn the focus knob and, if needed, the diopter adjustment on one eyepiece to get a sharp image for both eyes.

Is a pillar stand version available?
Yes, the Stereoscopic Dissection Microscopes are listed as available with a pillar stand. State in your enquiry whether you need the standard compact version or the pillar-stand version, and how many of each, so the quotation matches your laboratory layout.

How are the Stereoscopic Dissection Microscopes packed and stored?
The Stereoscopic Dissection Microscopes are compact, listed at 6¾ in long by 4½ in wide, and come in a wooden box. The box protects the optics from dust and knocks when the microscopes are stored between practical sessions or carried between rooms.

Mini Motor Unit (Product Code: SLE/PHY/89) is a small base-mounted DC motor used to show electrical energy being turned into motion in school physics and energy lessons. It runs from 1.5 to 4.5 V DC on a base of about 88 x 70 mm and is intended for use with a solar cell unit, so pupils can watch light drive a motor. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Mini Motor Unit Used For?

Connected to a solar cell unit, the Mini Motor Unit makes an energy-transfer chain visible: light becomes electrical energy, which the motor turns into movement. Shading the cell or moving a lamp closer shows pupils at once how motor speed depends on the light reaching the cell, making this a simple solar energy science kit activity for the classroom.

Because it works from 1.5 to 4.5 V DC, the unit can also run from one to three dry cells when there is not enough light, which is useful for comparing a battery supply with a solar one. Do not connect it to anything above 4.5 V, and keep the motor shaft free of dust and loose threads.

What to Specify When Ordering

• Number of motor units needed per class.
• Whether a matching solar cell unit should be quoted as well.
• The supply you intend to use, keeping within 1.5 to 4.5 V DC.

OEM Manufacturer

Jain Scientific Equipments Private Limited trades under the ScienceLab name and manufactures the Mini Motor Unit as the OEM at its factory at Saha, Ambala, Haryana. Energy and electricity apparatus from that factory reaches schools, dealers and importers directly, with no middle trader in the chain. Ask the manufacturer about replacement units or repeat orders when class sets need topping up. Read about the company on the profile page.

LED Blue (Product Code: SLE/PHY/91) is a pack of standard 5 mm blue light-emitting diodes used as indicators and light sources in electronics and physics practicals in schools and colleges. Each pack contains 100 LEDs, enough to keep a lab stocked for breadboard projects, circuit-building lessons and replacements across a term. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, alongside the same 5 mm LEDs in other colours.

Specifications

What Are the Blue 5 mm LEDs Used For?

Blue LEDs are used on breadboards and circuit boards as on/off indicators, in simple logic and sensor projects, and to show that a diode lets current pass in one direction only. Comparing blue with red or green LEDs also lets older students explore how the voltage needed to light an LED changes with its colour, a common LED characteristics experiment.

An LED should always be wired with a series resistor to limit the current, because connecting it straight across a cell or supply can destroy it. The longer lead is normally the positive (anode) connection. Keep opened packs dry and sealed so the leads stay clean between lessons.

What to Specify When Ordering

• Number of packs (each pack holds 100 blue LEDs).
• Any other LED colours you want quoted in the same order.
• Resistors, breadboards or LED boards needed to complete student circuits.

Supplier

Jain Scientific Equipments Private Limited, trading as ScienceLab, supplies these standard 5 mm blue LEDs as part of its physics and electronics consumables range. Schools and colleges can add LED packs to the same enquiry as their circuit apparatus, so components and equipment arrive in one consignment. Read more about the company on the ScienceLab profile page.

Browse the wider range of Physics Lab Equipment for circuit apparatus.

Frequently Asked Questions

How many LEDs are in a pack of LED Blue?
The LED Blue pack contains 100 standard 5 mm blue light-emitting diodes. Buying by the hundred keeps a school or college lab stocked for class projects and replacements, rather than ordering single LEDs each time one fails.

What size are the LED Blue diodes?
LED Blue diodes are the standard 5 mm size, which fits common breadboards, LED holders and circuit boards used in schools. The same 5 mm LEDs are also available in a range of other colours, listed as separate items.

Do the blue LEDs need a resistor?
Yes. Like any LED, each diode in the LED Blue pack should be connected with a suitable series resistor to limit the current. Without one, connecting it directly to a cell or power supply can damage the LED almost immediately.

Where can I find the electrical ratings for LED Blue?
The LED Blue listing gives the size, colour and pack quantity but not forward voltage, current or brightness figures. If your experiment needs these ratings, ask us through the contact page before ordering and we will advise on the batch quoted.

Electricity Circuits Kit (Product Code: SLE/PHY/92) is a panel-based electricity kit used for pupil investigations into simple circuits in primary and lower-secondary science. Each component, such as a switch, rheostat or bulb holder, sits on its own plastic panel with 4 mm sockets, and the panels are linked with 4 mm stackable leads instead of being fixed to a circuit board. The kit is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Electricity Circuits Kit Used For?

Because every component is a separate panel, pupils lay out a circuit on the desk just as it appears in a circuit diagram, which makes the link between symbol and real component easier to grasp. The kit covers complete and broken circuits, switching and changing lamp brightness with the rheostat, and it is flexible enough to move on to series and parallel work later. That makes it a practical physics experiment kit for schools that want pupils to design their own circuits rather than follow a fixed board layout.

The two polystyrene trays hold every panel in its place, so a technician can see at a glance whether anything is missing before the kit goes back on the shelf. Push the stackable leads fully into the 4 mm sockets, and pull them out by the plug rather than the cable to keep connections reliable.

What to Specify When Ordering

• Number of kits, based on how many pupil groups work at once.
• Whether 4 mm stackable leads should be quoted with the kits.
• Spare component panels, such as bulb holders, rheostats or push switches, for heavily used classes.
• Delivery location for packing and freight.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited (CIN U29309HR2020PTC087597), the OEM that manufactures this circuits kit. Production takes place at the company's licensed factory at 449, HSIIDC Industrial Area, Saha, Ambala, Haryana (Factory Licence AMB-ONLINE-CHD-J-414). Schools, dealers and importers buy the kit factory-direct and can ask the same source for spare panels when parts wear out. The company profile has further details.

Advance Research Polarising Microscope with Incident Light (Product Code: SLE/M/33) is an infinity-corrected trinocular microscope used for polarised-light study of rocks, minerals, ores and crystalline materials in transmission and reflection modes. Geology and materials departments use it with its plan achromatic POL objectives and colour CCD camera with imaging software. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, among its laboratory instruments in India and overseas.

Specifications

What Is the Polarising Microscope with Incident Light Used For?

Transmitted polarised light reveals the optical properties of transparent minerals in thin sections — birefringence, extinction and interference colours — while incident (reflected) light is needed for opaque material such as ore minerals, metals and polished sections that light cannot pass through. Having both paths on one frame lets a petrology or mineralogy class move from a thin section to a polished ore block without changing instruments.

In practice, the specimen is centred on the rotating graduated stage, observed between crossed polars, and turned to watch extinction positions. The wedge compensator, with its 0–4λ range, helps estimate retardation. The CCD camera and software then capture, measure and stitch images for reports, and the 15 frames per second output is useful for showing a live view to a group.

What to Specify When Ordering

• Whether the colour CCD camera and imaging software are required with the microscope
• Objective set needed (4X, 10X, 20X and 40X POL are listed)
• Your mains voltage for the LED power supply and a computer for the USB camera
• Quantity and any tender specification you must match

Supplier

Jain Scientific Equipments Private Limited, whose trading name is ScienceLab, supplies this polarising microscope from Ambala, Haryana. Universities, geological survey laboratories, institutes, dealers and importers in India and international markets can send their technical specification and receive a quotation for the matching configuration. See the company profile for more about ScienceLab.

• Research Trinocular Ore Microscope — with gypsum, mica and quartz wedge compensators and a vernier stage
• Single Disc Polishing Machine — for preparing polished specimen surfaces
• Mineral ID Starter Set — reference minerals for identification exercises

Other research and student instruments are in the Microscope category.

Frequently Asked Questions

Why does the Advance Research Polarising Microscope have incident light?
The Advance Research Polarising Microscope with Incident Light works in both transmission and reflection modes. Transmitted light is for thin sections of transparent minerals, while incident light, with its own polariser slider, lets you examine opaque ores, metals and polished sections.

Which objectives are fitted to this polarising microscope?
The Advance Research Polarising Microscope with Incident Light uses infinity-corrected plan achromatic POL objectives: 4X (N.A. 0.13, W.D. 17.0 mm), 10X (N.A. 0.3, W.D. 10.0 mm), 20X (N.A. 0.5, W.D. 2.1 mm) and 40X (N.A. 0.75, W.D. 1.1 mm).

What camera and software come with the microscope?
The Advance Research Polarising Microscope with Incident Light is specified with a colour CCD camera on the trinocular tube: 2/3 inch sensor, 1920 x 1080 pixels, 3.45 µm pixels, 12-bit conversion and 15 frames per second over USB, plus software for acquisition, measurement, object detection and image alignment.

What stage and condenser does it use?
The Advance Research Polarising Microscope with Incident Light has a circular, centerable mechanical stage that rotates through a graduated 360°, and a strain-free swing-out polarising condenser, so the polarised light is not disturbed by stress in the condenser glass.

What is the range of the wedge compensator?
The wedge-shaped compensator listed for the Advance Research Polarising Microscope with Incident Light has a measurement range of 0–4λ. Moving the wedge through the light path shifts interference colours, helping the user estimate retardation and birefringence of a mineral grain.

Is a calibration certificate available for this polarising microscope?

Simple Circuit Module Push Switch (Product Code: SLE/PHY/93) is an on/off push-button switch mounted on a base, used to open and close simple circuits in school electricity lessons. As part of the Simple Circuit Modules series, it lets pupils control LED boards, motors and buzzers from the same range with a press of a button. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Key Details

What Is the Push Switch Module Used For?

The push switch module gives pupils a hands-on way to see how a switch controls a circuit: press the button and the circuit changes state, press again and it changes back. Placed in series with an LED board it demonstrates a complete and a broken circuit. With two switch modules, pupils can model an output that works only when both switches are on (series) or when either one is on (parallel), a first step towards AND and OR logic.

Because the switch is fixed to its own base, it stays in place on the bench while pupils rearrange the rest of the circuit. Leave it in the off position while connecting the supply, and press the button firmly rather than striking it. It is a durable piece of junior science lab equipment for early electricity topics.

Contact Key (Push Switch) (Product Code: SLE/PHY/94) is a single contact key on a base, used to close a circuit only while it is pressed during physics practicals such as galvanometer and induction experiments. A plated spring arm with a press knob lifts clear of the contact as soon as it is released, and 4 mm terminals make the key quick to wire into a circuit. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Contact Key Used For?

A contact key is used wherever current should flow only for a moment: tapping it while watching a galvanometer, closing a circuit briefly to find the balance point on a meter bridge or potentiometer, or switching a coil on and off to show an induced current. Keeping the circuit closed only while a reading is taken also stops resistance wires and cells from warming up or running down, which improves the accuracy of student results.

Press the knob squarely so the spring arm meets the contact stud cleanly, and avoid holding it down longer than necessary. If connections become intermittent, wipe the contact surfaces and check that the 4 mm terminals are tight.

What to Specify When Ordering

• Number of contact keys, usually one per practical bench.
• 4 mm leads needed to connect the key into circuits.
• Delivery location for the quotation.

OEM Manufacturer
