Metal Testing Strips (Product Code: SLE/PHY/244) is a set of twelve lettered metal strips used to test which metals and alloys are attracted by a magnet in school and college magnetism experiments. This compact magnetism experiment kit mixes magnetic and non-magnetic samples, and each 50 x 25 mm strip carries a stamped key letter for easy identification. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Are Metal Testing Strips Used For?

Students bring a bar magnet up to each strip in turn and record, by key letter, whether it is attracted strongly, weakly or not at all. Because the key is a letter rather than a printed name, the activity works as a genuine test: learners predict first, then check against the teacher's list from A to L. The set includes instructive pairs, such as magnetic and non-magnetic stainless steel or galvanised and zinc-plated mild steel, so students see that appearance alone does not reveal magnetic behaviour.

The strips also support follow-on work, such as checking whether a zinc coating changes the result or using the brass, copper, phosphor bronze and nickel silver strips to show that many everyday alloys are non-magnetic. Keep the strips dry, and store them away from strong magnets so the steel samples do not stay magnetised between lessons.

What to Specify When Ordering

• The number of sets, usually one per student group.
• Whether magnets should be quoted with the strips, as the listing does not mention one.
• Whether you also want the Metal Discs – Set of 8 for metal-identification lessons.

Micro Voltmeter (Product Code: SLE/PHY/245) is a battery-powered, high-sensitivity voltmeter used to measure very small potential differences in school and college physics laboratories, as an effective and robust replacement for a spot galvanometer. It offers nine ranges starting at 100 µV, a large moving coil meter with push-button auto-zero, and 4 mm or UHF inputs. It is supplied to laboratories by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the Micro Voltmeter Used For?

The Micro Voltmeter measures potential differences far too small for an ordinary school voltmeter, such as the output of a thermocouple, the voltage across a low resistance or the small emf induced when a magnet moves near a coil. Its input resistance is considerably better than that of a spot galvanometer, so it draws very little current from the circuit and disturbs the experiment less.

Where schools in India once relied on a galvanometer, the meter also serves as a sensitive null detector for Wheatstone bridge and potentiometer experiments. Press the membrane button to auto-zero before each set of readings, begin on a less sensitive range and step down, and use the UHF socket with a shielded lead at the lowest voltages to reduce pick-up. Remove the PP3 battery if the meter is to be stored for a long time.

What to Specify When Ordering

• The number of meters needed for demonstration or student benches.
• Whether 4 mm leads or a shielded lead for the UHF socket should be quoted, as leads are not listed.
• The full-scale values your experiments need, so the nine ranges can be confirmed for you.
• Whether spare PP3 9 V batteries should be added to the order.

Supplier

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, based in Ambala, Haryana, India. The company supplies the Micro Voltmeter within its electrical measurement range for schools, colleges and institutional buyers in India and international markets, so a laboratory can order sensitive meters together with its other physics apparatus.

Frequently Asked Questions

What can the Micro Voltmeter measure?
The Micro Voltmeter measures very small potential differences on nine ranges, starting at 100 µV. Typical uses are thermocouple outputs, induced emfs and voltages across low resistances; ask ScienceLab for the complete range list if your experiment needs a particular full-scale value.

Why use the Micro Voltmeter instead of a spot galvanometer?
The Micro Voltmeter is a robust replacement for a spot galvanometer: its input resistance of 10 MΩ per volt is considerably better than a spot galvanometer's, and its large moving coil meter auto-zeros at the press of a membrane button.

How is the Micro Voltmeter powered?
The Micro Voltmeter runs from a PP3 9 V battery, so it needs no mains connection on the bench and moves easily between laboratories. Check the battery before a practical and remove it if the meter will be stored for a long period.

What inputs does the Micro Voltmeter have?
The Micro Voltmeter accepts signals through 4 mm sockets or, for very low voltages where a shielded lead is preferred, through a UHF socket. A 4 mm socket is provided for the negative input, so either connection method completes the circuit.

Who supplies the Micro Voltmeter?
The Micro Voltmeter is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab) of Ambala, Haryana, India, to schools, colleges, dealers and institutional buyers in India and international markets. Contact ScienceLab for availability, documentation and a quotation.

Is a calibration certificate available for the Micro Voltmeter?
Whether a calibration certificate can accompany the Micro Voltmeter should be discussed with ScienceLab before you order. Send your requirement through the contact page and the team will confirm what documentation is available for this instrument.

How big is the Micro Voltmeter?
The Micro Voltmeter case measures 208 x 155 x 115 mm (W x H x D), and its height including the handle is 187 mm, so it sits on a laboratory bench next to the experiment without taking much space.

Micrometer Screw Gauge, Lock Type (Product Code: SLE/PHY/246) is a precision hand instrument used to measure small outside dimensions, such as wire diameter or sheet thickness, from 0 to 25 mm in school and college physics laboratories. Built from nickel-plated brass with a ratchet top and a lock, this physics lab instrument reads to 1/100 mm and comes in a plastic case. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is a Micrometer Screw Gauge Used For?

In lab practicals across India, the screw gauge is used to measure the diameter of a wire, the thickness of a glass slide or metal sheet and the diameter of small spheres, each to the nearest 0.01 mm. It handles the wire-diameter step of experiments such as Young's modulus by Searle's method and the resistivity of a wire, and it teaches students about pitch, least count and zero error.

Always turn the thimble using the ratchet top so the same gentle pressure is applied at every reading, and check for zero error by closing the jaws before you start. Once a reading is set, the lock holds the spindle so the value can be read or shown to a teacher without shifting. Wipe the measuring faces clean and keep the gauge in its plastic case between practicals.

What to Specify When Ordering

• The number of gauges, typically one per student pair or group.
• Whether you want this lock-type model or the standard screw gauge also listed in the catalogue.
• Whether vernier calipers should be quoted as well for dimensions above 25 mm.

Microwave Accessories Hollow Plano-convex Lens (Product Code: SLE/PHY/247) is a large liquid-filled lens used to focus microwaves and demonstrate the refraction of electromagnetic waves in school and college physics laboratories. It consists of a thin moulded plastic dome, 260 mm in diameter, bonded to a 3 mm thick plastic plate 315 mm square, held upright on a channel base and filled with paraffin oil when in use. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Microwave Hollow Plano-convex Lens Used For?

Placed between a microwave transmitter and receiver, the oil-filled lens converges the beam in the same way a glass lens converges light, so students can find a focus by moving the receiver until the signal peaks. It shows a class that microwaves and visible light obey the same laws of refraction, and it pairs naturally with the other microwave accessories for reflection, polarisation and prism work.

Microwaves have a far longer wavelength than light, so microwave lenses are built much larger than glass ones; the 260 mm dome also makes the idea of a focal point easy to show to a whole class. Fill the lens with paraffin oil on a level bench, make sure the channel base is stable before switching the transmitter on, and drain and wipe the lens before storing it. As optics lab equipment for the electromagnetic-spectrum topic, it helps bridge ray optics and wave physics.

What to Specify When Ordering

• Whether paraffin oil for filling should be included in the quotation, as the listing does not say it is supplied.
• Whether your laboratory already has a microwave transmitter and receiver, or needs them quoted.
• Which other microwave accessories you need: hollow prism, rotating protractor or set of plates.

Microwave Accessories Hollow Prism (Product Code: SLE/PHY/248) is a hollow perspex prism used to show the refraction and deviation of microwaves in school and college physics experiments. Filled with paraffin it bends a microwave beam, and filled with water the same piece of physics lab equipment serves for optics experiments with light. It stands about 21 cm high with a longest side of roughly 30 cm and is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Microwave Hollow Prism Used For?

With the prism filled with paraffin and placed in the beam of a microwave transmitter, students move the receiver around the prism to find the direction in which the signal emerges, then measure the angle of deviation. Repeating the test with the prism empty suggests that the filling, not the thin perspex walls, does most of the bending, which shows clearly that microwaves refract in the same way as light.

Drained, rinsed and refilled with water, the prism becomes a large liquid prism for light-ray work with a ray box, so students can compare refraction in water with refraction in a solid prism from a standard optics lab equipment set. Keep perspex away from solvents and abrasive cleaners, which can craze or scratch it, and wipe it dry with a soft cloth after each use.

What to Specify When Ordering

• The number of prisms required.
• Whether paraffin for the microwave experiments should be quoted, as the listing does not say it is included.
• Whether a microwave transmitter/receiver and rotating protractor are also needed.

OEM Manufacturer

ScienceLab, the trading name of Jain Scientific Equipments Private Limited, is the OEM (original equipment manufacturer) of the Microwave Accessories Hollow Prism and makes it at the company's own licensed factory at Saha, Ambala, Haryana, India.

Microwave Accessories Rotating Protractor (Product Code: SLE/PHY/249) is an angle-measuring accessory used to measure the directivity of microwave transmission in school and college physics experiments. Students use it to read the angle between a microwave transmitter and receiver as the set-up is turned, converting signal readings into a clear picture of how the beam spreads. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Microwave Rotating Protractor Used For?

Directivity describes how strongly a transmitter sends energy in each direction. With the transmitter fixed and the receiver moved in steps around the protractor, students record the received signal at each angle and plot a polar diagram that shows the main beam and how quickly the signal falls away to either side.

The same angular scale helps when other microwave accessories are placed in the beam: measuring the angle of reflection from a metal plate, the deviation produced by a liquid-filled prism or the effect of turning a polarising grille. Align the zero mark with the transmitter axis before taking readings, and take several readings at each angle to average out fluctuations. Used this way, the protractor turns a qualitative microwave demonstration into a measured physics practical.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM (original equipment manufacturer) of the Microwave Accessories Rotating Protractor and produces it at its own licensed factory at Saha, Ambala, Haryana, India. Schools, colleges, dealers and importers buy it directly from the manufacturer, so questions about using it with an existing microwave kit, replacement parts or repeat orders go straight to the company that makes it. For institutional and tender buyers who need vendor registration details, the company's GSTIN is 06AAECJ8618A1ZT and its LEI is 3358004HRD1JIVXKYX49. Read more on the ScienceLab company profile.

Microwave Accessories Set of Plates (Product Code: SLE/PHY/250) is a set of five free-standing plates used to demonstrate the reflection, interference, partial transmission and polarisation of microwaves in school and college physics laboratories. It combines three aluminium plates, one perspex plate and a polarization grille, each on supporting feet so it stands upright in the beam. The set is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Microwave Set of Plates Used For?

A large aluminium plate acts as a mirror for microwaves, so students can check that the angle of reflection equals the angle of incidence, or face it towards the transmitter and move the receiver between them to detect standing waves. Standing the two large aluminium plates either side of the narrow 60 mm plate creates a double slit, and moving the receiver across the far side reveals the interference pattern — a microwave version of the Young double slit experiment.

The perspex plate reflects part of the beam and transmits the rest, which is useful when discussing partial reflection. The polarization grille shows that the transmitter's output is polarised: the signal passes in one orientation and falls sharply when the grille is turned through a right angle. Stand each piece firmly on its feet, keep the aluminium faces clean and flat, and store the set so the grille cannot be bent.

What to Specify When Ordering

• The number of sets required for your laboratory.
• Whether a microwave transmitter/receiver and rotating protractor should be quoted with the plates.
• Whether the hollow lens or hollow prism accessories are also needed to complete the kit.

OEM Manufacturer

The Microwave Accessories Set of Plates comes from Jain Scientific Equipments Private Limited, which trades as ScienceLab and is the OEM (original equipment manufacturer) of the set. It is produced at the company's own licensed factory in Saha, Ambala, Haryana, India, and supplied factory-direct to schools, colleges, laboratory dealers and importers in India and international markets. If a plate or the grille needs replacing, or you want to extend the kit, ask the manufacturer directly; see the ScienceLab profile for company details.

How is a double slit made with the Microwave Accessories Set of Plates?
A double slit is made with the Microwave Accessories Set of Plates by standing the two large aluminium plates in line with the narrow 60 mm plate between them, leaving two gaps. Moving the receiver across the far side then shows the microwave interference pattern.

What does the polarization grille in the Microwave Accessories Set of Plates show?
The polarization grille in the Microwave Accessories Set of Plates shows that microwaves are polarised: the received signal changes strongly as the 200 x 200 mm grille is rotated in the beam, being greatest in one orientation and smallest at right angles to it.

Millisecond Timer (Product Code: SLE/PHY/251) is an electronic laboratory timer used to measure short time intervals in school and college mechanics experiments, including finding the acceleration due to gravity (g) by free fall. It works with free-fall apparatus and/or light gates and also supports manual timing, with 2 switch input sockets and 4 rear sockets for light gates. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Key Details

What Is a Millisecond Timer Used For?

In the classic g-by-free-fall experiment, the timer starts when a ball is released and stops when it strikes a switch below, giving the fall time for a measured height. Repeating the drop from several heights lets students plot a graph and find g from its gradient. The two manual-switch sockets make the same unit useful for any start-stop event that is too quick to time with a hand-held stopwatch.

With light gates connected to the rear sockets, the timer records how long a card takes to pass through a beam, or the interval between two gates, so students can work out the speeds and accelerations of trolleys and gliders. That flexibility makes it a practical piece of mechanics lab equipment for motion, collision and free-fall work. Keep leads clear of moving parts and reset the display before each run so no earlier reading is carried over.

What to Specify When Ordering

• The number of timers needed for demonstration or student benches.
• Whether you need free-fall apparatus, light gates or both, and how many gates (up to the 4 rear sockets).
• Whether manual switches should be quoted for the 2 switch input sockets.

Supplier

ScienceLab is the brand name used by Jain Scientific Equipments Private Limited of Ambala, Haryana, India.

The Millisecond Timer is designed for the g by free fall experiment and for manual timing, and it can also time motion using light gates. Typical uses are finding the acceleration due to gravity, measuring trolley or glider speeds and timing short switch-controlled events.

How many inputs does the Millisecond Timer have?
The Millisecond Timer has 2 input sockets for connecting a manual switch and 4 input sockets at the back for connecting light gates. One unit can therefore handle simple start-stop timing as well as motion experiments that use several gates.

Does the Millisecond Timer work with light gates?
Yes. The Millisecond Timer can be used with G By Freefall apparatus and/or light gates, which connect to the 4 input sockets at the back. Tell ScienceLab which light gates you already have so the connection can be confirmed before you order.
