Apparatus for Demonstrating the Free Fall of Bodies (Product Code: SCL-393/04) is a demonstration device used to show how bodies fall freely under gravity, and how their mass and shape relate to that fall, in school physics classrooms. Its 30 mm steel spheres hang from a mounted steel frame on a 17 x 6 cm wooden block, so a teacher can release them in full view of the class. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Free Fall Apparatus Used For?

Teachers use it to challenge the everyday belief that heavier objects always fall faster. Compact bodies released together from the same height reach the floor together, whatever their mass, because gravity gives them the same acceleration. Comparing a steel sphere with a flat, light object such as a sheet of paper then shows how shape and air resistance slow some bodies down.

Fix the wooden block securely at the edge of a bench or on a stand so the spheres fall clear of the table, and place a tray or mat underneath to catch them. Keep students' hands away from the drop zone during each release. Once the class has seen the qualitative result, a timed practical with a stopwatch and tape makes a natural next step in a physics experiment sequence for school.

Apparatus for Determining "g" During the Free Fall of Bodies (Product Code: SCL-391/05) is a free-fall timing apparatus used to measure the acceleration due to gravity, g, from the time a steel ball takes to fall a known height in school and college physics laboratories. A micro-magnet holds the ball, contact pins start the timing on release and a contact plate stops it on impact. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a physics instruments supplier for teaching laboratories.

Specifications

What Is the g by Free Fall Apparatus Used For?

Students set a drop height on the column, place a steel ball on the magnet and release it; timing runs from the moment the contact pins open until the ball lands on the contact plate. Using h = ½gt², each height and time pair gives a value of g, and repeating the run at several heights lets students plot h against t² and take g from twice the gradient. Because the ball starts from a reproducible position and does not bounce at the bottom, repeat readings stay consistent.

Set the height carefully and read the column scale at eye level, since small height errors matter over short drops. Keep the contact surfaces clean, stop the balls from rolling off the bench, and use the tape measure to cross-check the column scale. The experiment is a standard mechanics practical for senior-school and first-year college physics.

What to Specify When Ordering

• Tape measure length: 1.5 m or 2 m, as listed.
• The number of sets for your student groups.
• Whether you want spare steel balls or an additional digital stopwatch.

Friction Demonstration Device (Tribometer) (Product Code: SCL-389/06) is an adjustable inclined-plane tribometer used to measure and compare friction between surfaces in school and college physics laboratories. Its 81.5 cm wooden plane rests at different angles from 0 to 45°, and a 200 g carriage with a small friction roller, a metal stand and weights of 10 to 100 g make it a complete friction experiment kit. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Tribometer Used For?

On the level plane, students load the carriage with weights and pull it with a spring balance, noting the force needed to start it moving and to keep it sliding steadily. Dividing each force by the weight of the loaded carriage gives the coefficients of static and kinetic friction, and repeating with heavier loads shows that friction rises in proportion to the normal force.

Tilting the plane slowly until the carriage just begins to slide gives the same result another way: the coefficient of static friction equals the tangent of that angle, which students can compare with their pulling results. Keep the plane clean and dry, since dust or moisture changes the readings, and make sure the stand is steady before raising the plane towards 45°. The set brings the friction and inclined-plane activities of a school physics course together in one piece of equipment.

What to Specify When Ordering

• The number of tribometers for your laboratory or student groups.
• Whether you need extra weights beyond the 10 g to 100 g set.
• Any spring balance or force meter for reading the pulling force, which is a separate catalogue item.

OEM Manufacturer

ScienceLab is the OEM behind the Friction Demonstration Device (Tribometer): it is made at the company's own licensed factory at Saha, Ambala, Haryana, India, rather than sourced from a reseller. Jain Scientific Equipments Private Limited, which trades as ScienceLab, supplies it factory-direct to schools, colleges, institutions, dealers and importers.

Disk for the Balance of Moments (Product Code: SCL-387/07) is a pivoted aluminium moment disk used to demonstrate the principle of moments and rotational equilibrium in school and college physics laboratories. The machined 245 mm disk turns smoothly on a ball bearing in a vertical plane, and its holes are set symmetrically in concentric circles so pins with scale pans can be placed at known distances from the axis. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Moment Disk Used For?

Students push pins into chosen holes, load the scale pans with weights and let the disk settle. Because the disk is balanced and turns freely on its bearing, it only stays still when the total clockwise moment equals the total anticlockwise moment, which students check by multiplying each load by its horizontal distance from the centre. The concentric rings of holes make those distances easy to read and repeat.

Placing a pin above or below the horizontal line through the axle shows that a moment depends on the perpendicular distance to the line of action, not on the straight-line distance to the hole. Before each run, check that the empty disk rests in any position; if it drifts, clean around the bearing and re-level the stand. This makes the disk a clear piece of physics practical equipment for lessons on levers, torque and equilibrium.

What to Specify When Ordering

• The number of disks for your laboratory or demonstration bench.
• The weight values you need — the hooked weights are listed as 50 g x 100 g, so confirm the mix with us.
• Whether you want spare pins or scale pans in addition to the four included.

OEM Manufacturer

The Disk for the Balance of Moments is an original ScienceLab product. Jain Scientific Equipments Private Limited, which trades as ScienceLab, is its OEM and makes it at the company's own licensed factory at Saha, Ambala, Haryana, India. Schools, colleges, dealers and importers deal with the manufacturer directly, so quotations, repeat orders and requests for replacement pins or scale pans come from the same team — ask us.

Set of Dynamometers (Product Code: SCL-385/08) is a graded set of tubular spring balances used to measure forces in newtons and loads in grams in school and college physics practicals. Teachers choose it because six colour-coded balances run from 250 g / 2.5 N up to 5 kg / 50 N, so one set covers both light and heavy loads. 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 Set of Dynamometers Used For?

A dynamometer lets students hang a load or pull on an object and read the force straight off the newton scale, while the gram scale beside it shows the equivalent mass. Common practicals include weighing everyday objects, measuring the drag needed to slide a block across the bench (friction), finding the pull required along an inclined plane, and weighing a body in air and then in water to find the upthrust. Comparing the two scales also shows students that each kilogram reads about 10 N on these balances.

For the most precise readings, pick the lowest range that will carry the load: the 250 g / 2.5 N balance for small objects, the 5 kg / 50 N balance for heavy ones. Hold the balance vertically with the hook empty and set the pointer to zero before every series of readings, and never load a balance past its marked maximum, because an over-stretched spring no longer reads correctly. As school physics lab equipment in India and abroad, one set normally serves a student group through the whole mechanics course.

What to Specify When Ordering

• The number of complete sets needed, remembering that each set holds six balances from 250 g / 2.5 N to 5 kg / 50 N.
• Which ranges your practicals use most, so we can discuss extra balances of those ranges with you.
• Any matching mechanics items to quote together, such as slotted weights or a Hooke's law apparatus.
• The delivery city or country, so packing and freight can be included in the quotation.

OEM Manufacturer

Jain Scientific Equipments Private Limited, which trades under the ScienceLab name, is the original equipment manufacturer (OEM) of this dynamometer set. The balances are produced at the company's own licensed factory at Saha, Ambala, Haryana, so schools, colleges, dealers and importers buy from the maker itself rather than from a trading intermediary.

If a single range is damaged in class, replacement balances and repeat orders are handled by the manufacturer directly — ask us about availability. Read more about the company on the ScienceLab company profile.

Apparatus for the study of the dependence of the acceleration of the body on force when the mass remains at C (Product Code: SCL-555/09) is a cart-and-track dynamics set used to show that acceleration rises with the applied force while the mass stays constant, in physics labs. It provides two 290 x 140 x 90 mm carts and two 1.5 x 0.3 m tracks, one straight and one curved. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Acceleration and Force Apparatus Used For?

This apparatus is built for the classic Newton's second law investigation. A cart runs along the straight track under a known pulling force, the force is changed step by step, and the resulting acceleration is worked out for each run. Because the moving mass is held constant, a graph of acceleration against force comes out as a straight line through the origin — the relationship the experiment sets out to prove. The curved track lets the same carts be used when the class moves on to motion along a curved path.

A dependable way to keep the total mass unchanged is to move hooked weights from the cart to the pulling load instead of adding new ones, so that only the net force changes between runs. Level the straight track first so the cart does not drift on its own, fix the gates in place with the supplied mounting accessories, and repeat every run two or three times before averaging. Used as a force motion experiment kit in senior classes, it gives students clean, repeatable data for their practical records.

What to Specify When Ordering

• How many sets each laboratory needs (one set = two carts plus two 1.5 x 0.3 m tracks).
• Whether additional hooked weights in the 50 g–100 g range should be quoted for larger groups.
• Whether you already have timing equipment such as a digital stopwatch, or want it included.
• The delivery destination, so that packing and freight can be included in the quotation.

OEM Manufacturer

Jain Scientific Equipments Private Limited, known by its trading name ScienceLab, is the OEM of this acceleration and force apparatus. The carts, tracks and fittings are made and assembled at the company's licensed factory in Saha, Ambala, Haryana, India, and supplied factory-direct to schools, colleges, institutions, dealers and importers.

Because the maker handles each order itself, questions about spare carts, extra weights or repeat supply go straight to the people who build the set — just ask us. Company details are on the ScienceLab profile page.

Frequently Asked Questions

What does the acceleration–force apparatus SCL-555/09 include?
The acceleration–force apparatus SCL-555/09 includes two carts (primary and secondary) measuring 290 x 140 x 90 mm, two 1.5 x 0.3 m tracks for straight and curved motion, primary and secondary gates with mounting accessories, a box of 50 g–100 g hooked weights, plastic side clamps and a demonstration table.

Which physics law does this apparatus demonstrate?
The SCL-555/09 acceleration–force apparatus demonstrates Newton's second law: with the body's mass held constant, its acceleration is directly proportional to the applied force. Students change the pulling force, measure the cart's acceleration each time and plot acceleration against force as a straight line.

Why does the set come with two different tracks?
The SCL-555/09 acceleration–force apparatus has two 1.5 x 0.3 m tracks: a straight one for rectilinear motion, used in the main constant-mass experiment, and a curved one, so the same carts can also show a body moving along a curved path.

How is the mass kept constant during the experiment?
With the SCL-555/09 acceleration–force apparatus, the usual method is to transfer hooked weights between the cart and the pulling load. The total moving mass then stays the same while the net force changes, which is exactly the condition this experiment requires.

Who manufactures the acceleration–force apparatus SCL-555/09?
The acceleration–force apparatus SCL-555/09 is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory in Saha, Ambala, Haryana, India. Schools, dealers and importers order it directly from the manufacturer.

Apparatus for Measuring the Density of Solids (Product Code: SCL-381/010) is a stand-mounted measuring set used to find the density of solid bodies from their mass and volume in school physics and general science labs. Its test bodies share one shape and size but differ in material — wood, plastic, bronze, aluminium, iron and lead — so students compare densities directly. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Density of Solids Apparatus Used For?

Density is mass divided by volume, and this set gives students both halves of the calculation. Each body is weighed on the scale or hung from the spring scale by its cotton thread, and its volume is found by lowering it into water in the 250 ml cylinder and reading the rise in level. Because every body has the same shape and size, their volumes match, so the class sees at once that the heavier bodies are simply the denser materials.

The steel base and rods form a rigid stand from which a body can hang freely, which also suits the weigh-in-air, weigh-in-water method: the apparent loss of weight in water equals the upthrust and leads to the volume. The wooden body usually floats, opening a discussion on why materials less dense than water do not sink. As mechanics lab equipment for secondary schools and colleges in India and overseas, the set works well with the student experiment descriptions and reports offered for it.

What to Specify When Ordering

• The number of sets required for your student groups.
• The weighing range your practicals need, so we can confirm the scale and spring scale supplied with the set.
• Whether the student experiment descriptions and reports should accompany the order.
• Any spare cylinders or additional test bodies you would like quoted alongside.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM that builds this density apparatus. The company is incorporated under CIN U29309HR2020PTC087597 and produces the steel stand, rods and accessories at its licensed factory at 449, HSIIDC Industrial Area, Saha, Ambala, Haryana (Factory Licence AMB-ONLINE-CHD-J-414).

Schools, colleges, dealers and importers buy the set factory-direct, and replacement rods, cylinders or test bodies as well as repeat orders are handled by the manufacturer itself — ask us. Learn more on the ScienceLab company profile.

Frequently Asked Questions

What materials are the test bodies made of?
The Apparatus for Measuring the Density of Solids includes test bodies of identical shape and size in different materials such as wood, plastic, bronze, aluminium, iron and lead, so students can compare the densities of materials without any difference in volume.

How is the volume of each body measured?
With the Apparatus for Measuring the Density of Solids, volume is normally found by displacement: the body is lowered on its cotton thread into water in the 250 ml cylinder and the rise in level is read. Weighing in air and then in water gives a second check.

What is the stand of the density apparatus made of?
The Apparatus for Measuring the Density of Solids stands on a 200 x 125 mm mild steel base with two 600 x 12 mm mild steel rods and a 200 x 10 mm steel rod, giving an especially stable and safe setup for hanging the bodies.

Are student experiment sheets available?
Yes. Student-suitable experiment descriptions with reports are available for the Apparatus for Measuring the Density of Solids. Mention them in your enquiry so that they can be included with the sets you order for your laboratory.

Who manufactures the Apparatus for Measuring the Density of Solids?
The Apparatus for Measuring the Density of Solids is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its licensed factory in Saha, Ambala, Haryana, India, and is supplied directly to schools, colleges, dealers and importers.

Can several sets be ordered, including for export?
Yes. The Apparatus for Measuring the Density of Solids can be supplied in multi-set quantities to institutions, dealers and importers in India and international markets. Send the number of sets and the delivery destination through the contact page for a quotation.

Apparatus for Demonstrating the Boil-Marriott Law (Product Code: SCL-379/011) is a gas-law demonstration unit used to show that the volume of a fixed mass of gas at constant temperature is inversely proportional to its pressure, in school and college physics classes. A horizontal transparent tube scaled 0–300 cm³ is read against a pressure gauge beside the gas tap, giving pairs of values for PV = constant. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Boyle's Law Apparatus Used For?

The apparatus lets a class test Boyle's law — called the Boyle–Mariotte law in many countries — with real numbers. Air is trapped in the transparent tube by closing the gas tap; the pressure is then changed step by step, and at each step the volume is read from the 0–300 cm³ scale and the pressure from the gauge. Multiplying each pair gives nearly the same product, and a graph of pressure against 1/volume comes out as a straight line.

Moving the rubber stopper sets the effective length of the tube, so the starting volume of trapped air can be chosen before a run. Make each change slowly and pause before reading, because compressing a gas warms it slightly and the law holds only at constant temperature; also make sure the tap is fully closed so no air escapes mid-series. As a Boyle law apparatus for schools and colleges in India and abroad, it turns a textbook formula into a measurement students can repeat themselves.

OEM Manufacturer

ScienceLab is the brand under which Jain Scientific Equipments Private Limited makes this gas-law apparatus as the original equipment manufacturer.

Frequently Asked Questions

What does the Boil-Marriott Law apparatus demonstrate?
The Apparatus for Demonstrating the Boil-Marriott Law (SCL-379/011) demonstrates Boyle's law: for a given mass of gas at constant temperature, volume is inversely proportional to pressure, so PV stays constant. Students record matching volume and pressure readings to confirm it.

What volume range does the tube cover?
The transparent, horizontally mounted tube of the Apparatus for Demonstrating the Boil-Marriott Law (SCL-379/011) carries a volume scale from 0 to 300 cm³, and the volume of trapped gas is read directly from this scale at every pressure setting.

How is the gas pressure measured?
Pressure in the Apparatus for Demonstrating the Boil-Marriott Law (SCL-379/011) is read on a pressure gauge located next to the gas tap that closes the tube, so each volume reading can be paired with the pressure of the enclosed gas.

What is the rubber stopper for?
In the Apparatus for Demonstrating the Boil-Marriott Law (SCL-379/011), changing the position of the rubber stopper selects the effective length of the tube, which sets how much air is enclosed before the pressure and volume readings begin.

Who manufactures the Apparatus for Demonstrating the Boil-Marriott Law?
The Apparatus for Demonstrating the Boil-Marriott Law (SCL-379/011) is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory in Saha, Ambala, Haryana, India. Quotations and repeat orders come straight from the manufacturer.

Is this the same as a Boyle's law apparatus?
Yes. The Boyle–Mariotte law is another name for Boyle's law, so the Apparatus for Demonstrating the Boil-Marriott Law (SCL-379/011) serves as a Boyle's law apparatus. Ask us through the contact page if your syllabus lists it under a different name.
