IC Chip (Product Code: SCL-449/121) is a leaded DIP integrated circuit used to build timer, oscillator and pulse circuits in electronics and physics laboratories. It is offered in different configurations and type numbers, including the widely taught 555 timer, and is listed for 5 V operation. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, to schools, colleges and project students.

Specifications

What Is the IC Chip Used For?

The 555 timer is one of the first integrated circuits students meet, because a few resistors and a capacitor turn it into a working timer. Wired as a monostable it gives a single time delay; as an astable it runs as an oscillator that can flash an LED or sound a buzzer; and it can also act as a flip-flop element. Derivative packages provide up to four timing circuits in one chip.

The DIP (dual in-line package) format fits breadboards and IC sockets, which suits trial-and-error circuit building in class. Insert the chip with its pin-1 notch or dot facing the right way, keep the supply to the 5 V rating, and touch an earthed surface before handling to discharge static. From simple LED flashers, students can progress to pulse width modulation and sequential timing, making the IC a useful piece of science lab equipment for class 12 electronics topics.

Capacitor (Product Code: SCL-451/122) is an electronic component that stores electric charge, used in charging and discharging, filtering and timing experiments in physics and electronics labs. It is listed with a 250 V voltage rating, well above the supplies used in typical low-voltage student circuits, together with a 105 °C temperature rating and a tolerance of 20%. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as a regular part of any electricity experiment kit for school labs.

Specifications

What Is the Capacitor Used For?

Capacitors store charge and release it again, which puts them at the centre of RC time-constant experiments: students charge a capacitor through a resistor and record how its voltage rises, then discharge it and watch the voltage fall. The same component smooths the output of rectifier circuits, blocks DC while passing AC signals, and sets the timing interval in timer IC circuits.

Observe polarity if the capacitor has marked positive and negative leads, and never exceed the 250 V rating. A capacitor can hold charge after the supply is removed, so discharge it through a resistor before handling it. The 20% tolerance means the measured capacitance may differ from the marked value, which is worth discussing when students compare calculated and measured time constants.

What to Specify When Ordering

• Capacitance value(s) required, as these are not stated on this page.
• Working voltage of your circuit, to confirm the 250 V rating suits it.
• Quantity per experiment set or bench.
• Whether a Capacitor Study Kit or charging and discharging apparatus is also needed.

Electric Tester (Product Code: SCL-455/124) is a hand-held voltage tester used to check whether a conductor, socket or terminal is live in electrical workshops and school physics labs. Made of spring steel and acetate in a yellow finish, it is listed for a working voltage of 220 V and described as high-sensitivity and shock-proof. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the Electric Tester Used For?

Lab technicians and electrical trainees use the tester to confirm whether mains sockets, switchboards and wiring terminals are live before and after work, and to identify the phase conductor when wiring a plug or lamp holder. In a school lab setup in India it belongs to the basic tool set used when installing demonstration boards and checking the supply points that feed apparatus.

Try the tester on a known live point first so you know it is working, hold it only by the insulated body, and keep fingers away from the metal tip. Use it only within its 220 V working voltage, and treat its indication as a first check rather than proof that a circuit is dead: isolate the supply at the switch or breaker before touching any conductor.

Supplier

The Electric Tester is supplied by Jain Scientific Equipments Private Limited, which trades as ScienceLab, from Ambala, Haryana, to electrical workshops, school labs, vocational training centres and dealers in India and international markets. Many buyers add testers to tool kits and wiring accessories when fitting out an electricity lab. See the ScienceLab company profile for background on the company.

Spirit Level (Product Code: SCL-458/125) is a bubble-vial levelling tool used to check that benches, bases and apparatus sit truly level in physics labs and workshops. This compact 4-inch model has an aluminium body, a magnetic base that holds onto steel surfaces, and a yellow finish that is easy to spot on the bench. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the Spirit Level Used For?

Many physics experiments assume a level surface: an optical bench, a physical balance, a friction table or the base of a Searle's apparatus gives misleading readings if it tilts. The spirit level lets students confirm this in seconds by placing it on the surface and adjusting levelling screws or packing until the bubble settles between the centre marks, making it a small but frequently used item of physics lab equipment in schools across India.

The magnetic base keeps the level in place on steel stands, machine beds and metal frames, leaving both hands free for adjustment. Its 4-inch length fits on small platforms and apparatus bases where a long level cannot sit. To check the level itself, place it on a flat surface, note the bubble, then turn it end-for-end: the bubble should settle in the same place.

Supplier

Jain Scientific Equipments Private Limited supplies the Spirit Level under its ScienceLab trading name from Ambala, Haryana, to school labs, colleges, workshops and dealers in India and international markets. Institutional buyers who need vendor details for registration can use GSTIN 06AAECJ8618A1ZT and LEI 3358004HRD1JIVXKYX49 for the supplying company. Read the ScienceLab company profile for more.
