Apparatus Newton's Second Law (Product Code: SLE/PHY/16) is a clamp-mounted spring launcher used to help students visualize and grasp Newton's Second Law of Motion in school physics labs. The sturdy unit projects one ball horizontally while another drops vertically, and both land at the same time; its spring can propel a ball 48 inches from the starting point. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, for school physics lab equipment sets in India and abroad.

Specifications

What Is the Newton's Second Law Apparatus Used For?

Once released, each ball has only one force acting on it, its weight, which points straight down. By Newton's second law, the same force per unit mass gives both balls the same downward acceleration, so the one that is launched sideways and the one that simply drops reach the floor together. No horizontal force acts after launch, so the projected ball keeps a steady sideways speed as it falls. Students see and hear the second law at work.

Clamp the unit with its detachable rod to the edge of a bench or to a laboratory stand so it stays rigid when the spring fires. With the horizontal range of up to 48 inches marked on the floor and the launch height measured, older students can calculate the launch speed and fall time. Keep the landing area clear and let the class predict the result before each trial.

Apparatus Young Modulus Searle's (Product Code: SLE/PHY/17) is a twin-frame extension apparatus used to determine the Young's modulus of a wire by Searle's method in college and senior-secondary physics labs. Two hinged cast metal frames, a spirit level on a pivoted cross-bar and a micrometer head reading to 0.01 mm let students measure very small extensions; brass and steel wires are included. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Searle's Young Modulus Apparatus Used For?

Young's modulus tells us how stiff a material is, and Searle's method measures it on a long, thin wire. The two wires hang from the chucks of the ceiling bracket and pass into the self-centering chucks of the two frames. One frame carries the counterpoise weight to keep its wire taut as a reference, while load is added to the hook of the other. Because the frames are hinged to move only vertically, any stretch of the loaded wire tilts the spirit level on the cross-bar.

After each load change, the micrometer head is turned until the bubble is level again, and the change in reading gives the extension to 0.01 mm. Plotting load against extension, then using the wire's length and diameter, gives Young's modulus as stress divided by strain. The Searle's method Young's modulus experiment is a standard practical in India's senior-secondary (including CBSE class 11) and undergraduate physics courses. Add and remove load gently, and stay well within the elastic limit so the wire returns to its original length.

What to Specify When Ordering

• Number of complete apparatus sets required for the lab.
• Whether you need extra brass or steel wires beyond the set of two supplied.
• Loading weights and hanger, which are not listed in the kit contents.

Balance Demonstration Fulcrum/Lever (Product Code: SLE/PHY/18) is a meter-stick lever set used to teach the relationship between the length of a lever arm, the moment of a force and the amount of force, in school physics labs. With a meter stick, a stand, three knife-edge clamps and 50 gram and 100 gram hooked weights, students balance real loads and see the law of moments at work. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Lever and Fulcrum Balance Used For?

One knife-edge clamp on the meter stick rests on the stand as the fulcrum, and the other two clamps carry the 50 gram and 100 gram hooked weights. Students slide the weights along the stick until it balances, then read each distance from the fulcrum straight off the stick's scale. They soon find that the 50 gram weight must hang twice as far from the pivot as the 100 gram weight, because the moments on either side must be equal: force multiplied by distance on the left equals force multiplied by distance on the right.

Moving the fulcrum away from the centre brings the stick's own weight into play, which lets older students locate its centre of gravity or estimate its mass from the balance point. The set works well as a moment bar apparatus for school practicals and as a quick teacher demonstration of why a long spanner or crowbar makes work easier. Handle the knife edges carefully and keep them clean so the stick pivots freely.

OEM Manufacturer

ScienceLab is how Jain Scientific Equipments Private Limited trades, and the company is the OEM (original equipment manufacturer) of the Balance Demonstration Fulcrum/Lever. The set is manufactured at its licensed factory at Saha, Ambala, Haryana, India, then supplied factory-direct to schools, colleges, dealers and importers. Extra knife-edge clamps, replacement weights or repeat class sets are handled by the manufacturer itself, so just ask us. Read more on the company profile.

Frequently Asked Questions

What does the Balance Demonstration Fulcrum/Lever teach?
The Balance Demonstration Fulcrum/Lever teaches the relationship between the length of a lever arm, the moment of force and the amount of force. By adjusting weights on the meter stick until it balances, students observe the law of torque, also called the principle of moments.

What parts are in the fulcrum and lever balance set?
The Balance Demonstration Fulcrum/Lever consists of a meter stick, a stand, three knife-edge clamps, one 50 gram hooked weight and one 100 gram hooked weight. One clamp forms the fulcrum on the stand and the other two hold the weights on the stick.

How do students find the balance point with this lever set?
With the Balance Demonstration Fulcrum/Lever, students move the hooked weights along the meter stick until it rests level, then read each distance from the fulcrum. Multiplying each weight by its distance shows that the moments on both sides are equal at equilibrium.

Who manufactures the Balance Demonstration Fulcrum/Lever?

Balance Spring Tubular Plastic (Product Code: SLE/PHY/19) is a tubular spring balance used to measure forces, such as the pull of gravity on a mass, in school physics and science labs. It is 250 mm long overall including its ring and hook, the spring mechanism is clearly visible through the plastic tube, and it carries a zero adjustment plus colour-coded ranges scaled in both grams and newtons. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Tubular Spring Balance Used For?

A spring balance is often the first force-measuring instrument students handle. Hang the balance by its ring, set the pointer to zero with the zero adjustment, then attach the load to the hook and read the scale. Because the scale is marked in both grams and newtons, one reading lets the class connect mass and weight and see how a load in grams corresponds to a force in newtons. The visible spring shows how the extension grows with the load, a direct link to Hooke's law.

Beyond weighing, students use it to measure friction by dragging a block across the bench, the pull needed to raise a load with pulleys, or the effort on a lever. The colour coding makes it easy to hand the right range to each group and to collect them again after class. Hold it vertically when weighing, re-zero before each set of readings and never load it past the end of its scale. It is everyday physics lab equipment in India's schools and junior colleges.

What to Specify When Ordering

• The range or ranges you need; each range is colour-coded, so ask us which ranges are available.
• Quantity per range, for example one per student group.
• Whether you want a mixed set of ranges for one lab.

OEM Manufacturer

Jain Scientific Equipments Private Limited trades as ScienceLab and is the OEM for the Balance Spring Tubular Plastic.

Bar Compound Copper & Iron (Product Code: SLE/PHY/20) is a bimetallic compound bar used to demonstrate the principle of the thermostat in school physics and general science labs. An iron strip and a copper-based strip are riveted together from end to end and mounted in a wooden handle, and when the bar is heated the unequal expansion of the two metals makes it bend. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Compound Bar Used For?

As a piece of physics lab equipment for India's heat and expansion lessons, it takes only a flame to use. Hold the bar by its wooden handle and pass it slowly through the flame so both strips warm evenly. The copper-based strip expands more than the iron for the same rise in temperature, but the rivets stop the strips from sliding past each other, so the whole bar curls with the iron on the inside of the curve. As it cools, the bar straightens again, showing that the effect is reversible.

That bending movement is exactly what switches a thermostat: in an iron, a room heater or a fire alarm, a bimetal strip moves as it warms and opens or closes an electrical contact. Students can predict which way the bar will bend before heating, then check. Keep the heating gentle, rest the hot bar on a heat-proof mat afterwards, and never touch the metal until it has cooled.

What to Specify When Ordering

• Confirm the metal pair you need: the product name lists copper and iron, while the earlier catalogue text lists brass and iron.
• Number of compound bars, for example one per student group or one for teacher demonstration.
• Whether a heat source such as a Bunsen burner should be quoted with the bars.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM (original equipment manufacturer) of the Bar Compound Copper & Iron. The company manufactures it at its licensed factory in Saha, Ambala, Haryana, India, and sells factory-direct to schools, colleges, dealers and importers. Jain Scientific Equipments Private Limited is a registered MSME whose major activity is manufacturing (Udyam UDYAM-HR-01-0003714), and export consignments move under Importer-Exporter Code AAECJ8618A issued by the DGFT. See the company profile for more.

Related Physics Lab Equipment

For a full set of thermal expansion demonstrations, pair the compound bar with:

• Bimetallic Strip — another bimetal item for the same thermostat lesson.
• Ball & Ring Apparatus — shows expansion of a solid when heated in a single metal.
• Apparatus Bar & Gauge — demonstrates linear expansion of a heated bar.
• Bunsen Burner — a heat source for warming the bar evenly.

More apparatus is listed in Physics Lab Equipment.

Frequently Asked Questions

What does the Bar Compound Copper & Iron demonstrate?
The Bar Compound Copper & Iron demonstrates the principle of the thermostat. Its two riveted metal strips expand by different amounts when heated, so the bar bends, just as the bimetal strip inside a thermostat bends to open or close an electrical contact.

Which way does the compound bar bend when heated?
When the Bar Compound Copper & Iron is heated, it bends with the iron strip on the inside of the curve, because the copper-based strip expands more than iron. On cooling, the bar returns towards its original straight shape.

What metals is the compound bar made of?
The Bar Compound Copper & Iron joins an iron strip to a copper-based strip, riveted from end to end in a wooden handle. The product name lists copper, while our earlier catalogue text lists brass, so please confirm the metal pair with ScienceLab when you enquire.

Who manufactures the Bar Compound Copper & Iron?
Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, manufactures the Bar Compound Copper & Iron as the OEM at its own factory in Saha, Ambala, Haryana, India. It is supplied factory-direct to schools, colleges, dealers and importers.

How should the compound bar be heated safely?
Hold the Bar Compound Copper & Iron only by its wooden handle and warm it gently and evenly in a flame. Place the hot bar on a heat-proof mat after the demonstration and do not touch the metal strips until they have cooled completely.

Battery Clip, PP3 (Product Code: SLE/PHY/21) is a standard snap-on battery connector used to take power from a PP3 battery into simple circuits in school physics and electronics labs. It has 150 mm leads and fits both PP3 batteries and press-stud type battery holders, so one clip style serves both power options on the bench. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as a basic part for any electricity experiment kit a school assembles.

Specifications

What Is the PP3 Battery Clip Used For?

A PP3 battery has two press-stud terminals of different sizes at one end, and the clip snaps onto them in only one orientation, so the battery cannot be connected the wrong way round at the clip. The 150 mm leads then carry the supply to the rest of the circuit, whether that is a bulb holder, a buzzer, a small motor or a breadboard. The same clip also snaps onto press-stud type battery holders, which lets a class switch between a PP3 battery and a holder of cells without rewiring.

Before wiring, note which lead goes to the positive terminal and keep that polarity throughout the circuit. Never let the two lead ends touch while a battery is attached, as that shorts the battery and heats the wires. Unclip the battery at the end of each lesson so it does not drain in storage, and bend the leads gently so the joints at the clip last longer.

Supplier

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, which supplies the Battery Clip, PP3 from Ambala, Haryana, India. The company sources it as a standard component and ships it with other electricity and circuit items, so a school or dealer can place a single order for the whole circuit list. Ask us about quantities for class kits or for dealer stock. Company information is on the ScienceLab profile page.

Battery Snap with Crocodile Clip (Product Code: SLE/PHY/22) is a battery connector with crocodile clips attached, used to link a battery quickly to circuit components in school science and physics lessons. Because the clips grip terminals, wires and component legs directly, students can build and change circuits on the desk without screwdrivers or soldering. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, and is a handy part of any hands-on science kit for primary school and middle-school classes.

Key Details

What Is the Battery Snap with Crocodile Clip Used For?

Young students often struggle with small terminal screws, and loose connections are the most common reason a first circuit fails. With this connector the battery snaps on at one end and the crocodile clips at the other bite straight onto a bulb holder terminal, a switch, a buzzer lead or a bare wire. A circuit can be built, tested and rearranged in seconds, which keeps attention on the science rather than the wiring.

Teachers use it for series and parallel circuit activities, for testing which materials conduct electricity, and for quick demonstrations at the front of the class.

Bernoulli Tube Apparatus (Product Code: SLE/PHY/23) is a glass flow-tube set used to explain Bernoulli's theorem by showing how the pressure and speed of a flowing liquid change with the bore of a tube, in physics labs. It pairs a Bernoulli tube with a central narrowed portion and a constant-bore gradient tube, each 500 x 13 mm with three side tubes for glass manometers. This physics demonstration kit is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Bernoulli Tube Used For?

Water from a steady supply is run through one flow tube at a time, with a length of glass tubing standing upright in each side tube as a manometer and a swan-necked outlet at the far end. In the constant-bore gradient tube, the water levels in the three manometers fall evenly along the tube, showing the pressure drop along a uniform pipe. In the Bernoulli tube, the middle manometer, which taps the narrowed portion, stands noticeably lower than its neighbours.

That dip is Bernoulli's theorem in action: to pass the same volume each second through the constriction, the water must speed up, and its pressure falls. Comparing the two tubes side by side separates this effect from the ordinary friction loss. Keep the flow steady, clamp the manometer tubes upright, and handle the glass with care when fitting the rubber connectors. It is a clear, low-cost piece of physics lab equipment in India's senior-secondary and college fluid-flow practicals.

What to Specify When Ordering

• Number of complete sets; each set includes both flow tubes, 6 glass tubing lengths, 2 swan-necked outlets and 8 rubber connectors.
• Any spare glass tubing lengths or rubber connectors you want quoted.
• Stands or clamps for holding the manometer tubes upright, if your lab needs them.

OEM Manufacturer

Jain Scientific Equipments Private Limited, known by its trading name ScienceLab, is the OEM of the Bernoulli Tube Apparatus. The set is manufactured at the company's licensed factory at Saha, Ambala, Haryana, India, and supplied factory-direct to schools, colleges, dealers and importers. Because glassware can break in use, replacement flow tubes, glass tubing or connectors are handled by the manufacturer itself — just ask us. More detail is on the ScienceLab profile page.

The Bernoulli Tube Apparatus includes a Bernoulli tube with a central narrowed portion, a constant-bore gradient tube, 6 lengths of glass tubing, 2 swan-necked outlet tubes and 8 small pieces of rubber connecting tubing for joining the glass parts.

What size are the Bernoulli apparatus flow tubes?
Each flow tube of the Bernoulli Tube Apparatus measures 500 x 13 mm (length x outer diameter). Each has three sealed-in side tubes, 25 mm long and spaced about 150 mm apart, where glass tubing lengths are attached as manometers.

Why does the set include a constant-bore gradient tube?
The constant-bore gradient tube in the Bernoulli Tube Apparatus shows the steady pressure fall along a uniform tube. Comparing it with the Bernoulli tube lets students separate the pressure drop caused by the constriction from the ordinary loss along the length of the tube.

Who manufactures the Bernoulli Tube Apparatus?
Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, manufactures the Bernoulli Tube Apparatus as the OEM at its own factory in Saha, Ambala, Haryana, India. It is supplied factory-direct, and replacement glass parts can be requested from the manufacturer.
