Doppler Effect (Product Code: SLE/PHY/158) is a demonstration apparatus used to let a class hear the Doppler effect — the change in pitch from a moving sound source — in physics lessons on sound and waves. It consists of a plastic box with a sound source that runs on 9 V batteries (not included) and a strong string for whirling it in a circle. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the Doppler Effect Apparatus Used For?

With the sound source switched on, the teacher whirls the box in a circle on its string. Students standing to one side hear the pitch rise as the box moves towards them and fall as it moves away, while the person swinging it hears an almost steady note because their distance from the box hardly changes. That contrast is a memorable way to show that the effect depends on relative motion between source and listener.

The demonstration leads naturally to everyday examples such as passing sirens, and to applications like speed measurement and the red shift of distant galaxies. Use a hall or open space, check the string and its attachment before each session, and keep students well back from the swinging box. It is a compact Doppler effect kit that fits into any sound wave experiment unit for schools in India and abroad.

Dynamics Kit, Track & Accessories (Product Code: SLE/PHY/159) is a force and motion experiment kit used to study velocity, acceleration, momentum and Newton's laws in school and college physics labs. It brings together a 1.2 m aluminium track, two high-impact moulded trolleys (one spring loaded), masses, a ticker tape timer and carbon discs as one matched set for curriculum-based experiments. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Dynamics Kit Used For?

The kit covers the core mechanics practicals in one box. Students run a trolley down the tilted aluminium track while the ticker tape timer marks dots at regular intervals, then use the dot spacing to calculate velocity and acceleration. Adding the 10 g masses or the trolley weight changes the mass being accelerated, which leads straight into Newton's second law. The spring-loaded trolley and its partner are used for collision and "explosion" experiments on conservation of momentum.

For cleaner results, first raise one end of the track just enough for a gently pushed trolley to run at constant speed; evenly spaced dots show that friction has been compensated. Note that ticker tape and a power supply for the timer are not listed among the kit contents, so check what your lab already has. It is a practical force motion experiment kit for schools and colleges in India and abroad.

What to Specify When Ordering

• Number of kits — usually one per student group.
• Ticker tape and a suitable supply for the timer, if your lab does not already have them.
• Extra trolleys, timers or carbon discs for larger classes.
• Delivery location within India or overseas.

Dynamics Trolley, Plastic (Product Code: SLE/PHY/160) is a rigid ABS plastic laboratory trolley used for kinematics, collision and momentum experiments in school and college physics. It has accurately aligned, very low-friction wheels, an accurate mass of 600 g and velcro pads for inelastic collisions, and it can withstand loads up to 60 kg. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Plastic Dynamics Trolley Used For?

The accurate 600 g mass means students can put the trolley straight into momentum and force calculations without weighing it first. Stacking one trolley on another doubles the moving mass, and the high load capacity allows extra masses to be piled on for Newton's second law investigations. Very low-friction wheels keep losses small, so results from collisions and accelerations stay close to theory.

For collisions, the velcro pads make two trolleys stick together to model a perfectly inelastic impact, while the two-position firing pins push trolleys apart for "explosion" experiments. Keep the firing pin on its locking catch until the moment of release, and store trolleys stacked to save bench space. It is a rigid, practical piece of mechanics lab equipment for schools and colleges in India and abroad.

What to Specify When Ordering

• Number of trolleys — collision and explosion experiments need at least two per group.
• Whether you would prefer the complete Dynamics Kit, Track & Accessories instead of single trolleys.
• Any ticker tape timers, pulleys or masses needed for the experiments you plan.
• Delivery location for the quotation.

Dynamics Trolley, Wooden (Product Code: SLE/PHY/161) is a pair of 300 mm long wooden trolleys on three wheels, used to demonstrate impulse, recoil and momentum in school physics lessons. A spring-loaded rod is fitted to give an impulse when released, which is used to drive the two trolleys apart in simple recoil experiments. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Wooden Dynamics Trolley Used For?

The classic use is the recoil or "explosion" experiment. The two trolleys are placed end to end, the spring-loaded rod is set, and on release the trolleys shoot apart in opposite directions. With equal loads they travel roughly equal distances; add extra mass to one and it moves off more slowly, which gives students a clear, hands-on feel for Newton's third law and conservation of momentum.

Because the pair is simple to set up, it suits younger classes meeting forces and motion for the first time, before they move on to ticker-timer measurements. Keep the wooden trolleys dry, store them flat and check that the wheels turn freely before each lesson. The set is a straightforward addition to physics lab equipment for schools in India and overseas.

What to Specify When Ordering

• Number of pairs required — the trolleys come as a pair.
• Masses for loading one trolley in unequal-mass recoil experiments.
• Whether plastic trolleys or the full dynamics kit with track and timer should be quoted as well.

OEM Manufacturer

EHT Power Supply (Product Code: SLE/PHY/162) is an extra-high-tension laboratory power supply used to drive electron tubes and electrostatic experiments in college and advanced school physics labs. It gives a fully isolated, continuously variable output of 0–2.5 kV or 0–5 kV DC at a maximum of 2 mA, shown on a bright 12.5 mm green LED display, plus a 6.3 V AC auxiliary output for cathode heaters. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the EHT Power Supply Used For?

Electron-beam tubes need a high accelerating voltage on the anode and a low-voltage supply for the cathode heater. This unit provides both: the variable EHT output accelerates the beam, and the 6.3 V AC auxiliary output heats the cathode, so one supply can run deflection and fine-beam experiments such as measuring the specific charge of the electron. The bright LED display lets the class read the accelerating voltage as it is adjusted.

For electrostatics, the secondary outputs pass through 25 MΩ resistors, which limit the short-circuit current to 60 µA while still delivering a high voltage for charging plates and electroscopes. High voltage demands care: only trained staff should set up the unit, use shrouded leads where possible, turn the output to zero before making connections, and use the independent earth terminal as the experiment requires.

What to Specify When Ordering

• The tubes or electrostatic experiments you plan to run, so matching tubes and holders can be quoted together.
• Whether shrouded leads are needed for the output sockets.
• Your local mains supply, checked against the listed 220–240 V input.
• Any documentation required, such as a calibration certificate — ask us before ordering.

Electrode Foil Holders (Product Code: SLE/PHY/163) are plastic strips with 4 mm socket terminals and two crocodile clips, used to hold electrode foils in place and connect them into a circuit during electricity and electrochemistry practicals. Listed as "Foils, Pack of 5", they let students set up simple cells, electrolysis and electroplating experiments with the foils held steady and wired through standard 4 mm leads. They are made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Are Electrode Foil Holders Used For?

Thin metal foils are awkward to keep upright in a solution and even harder to connect reliably. The holder solves both problems: its crocodile clips grip the foils, and the 4 mm socket terminals take ordinary laboratory leads to a meter or power supply. Typical experiments include building simple cells from two different metal foils, ranking metals in an electrochemical series by the voltage they produce, electroplating copper onto another foil, and electrolysis of salt solutions.

For consistent readings, clean the foils before each run and keep the crocodile clips above the liquid so they do not corrode or take part in the reaction. Rinse and dry the holders after practicals and store them with the foils. They are a small but useful part of any electricity experiment kit for school labs in India and abroad.

What to Specify When Ordering

• Number of packs — the item is listed as foils, pack of 5; confirm the pack contents in your quotation.
• Whether you also need the Electrode Rod Holders version for carbon or metal rods.
• Metal foils or strips and 4 mm leads to use with the holders.

Electrode Rod Holders (Product Code: SLE/PHY/164) are plastic strips fitted with two crocodile clips and 4 mm socket terminals, used to grip electrode rods and wire them to a power supply in electrolysis and conductivity experiments. Listed as "Rods, Pack of 5", they hold a pair of carbon or metal rods steady in the solution so students can concentrate on what happens at each electrode. They are made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Are Electrode Rod Holders Used For?

Electrolysis with carbon rods is one of the most common school practicals, and it gives clear results only when the rods stay still. Clip two rods into the holder, lower them into the electrolyte and connect the 4 mm sockets to a low-voltage DC supply; students can then watch metal deposit on the cathode and gas form at the anode, and test the products. The same set-up checks whether a solution conducts, using a lamp or meter in series.

Carbon rods are brittle, so clip them gently near the top and keep the crocodile clips clear of the liquid. Use red and black leads to keep track of polarity, switch off before removing the rods, and ventilate the room when electrolysing chloride solutions. The holders are a practical item among chemistry and physics lab equipment for schools in India and abroad.

What to Specify When Ordering

• Number of packs — listed as rods, pack of 5; ask us to confirm exactly what each pack contains.
• Electrode rods to use with the holders, such as carbon rods, if you need them separately.
• A low-voltage DC supply and 4 mm leads for each group.
• Whether the Electrode Foil Holders version should be added for foil electrodes.

Electromagnetic Spectrum Chart (Product Code: SLE/PHY/165) is a large visual aid used to show students how the unseen electric and magnetic waves around us are arranged by wavelength and frequency in school and college physics classrooms. At 69 cm x 99 cm (height x width) it can be read by a whole class, and it is accompanied by an explanatory sheet. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer of physics lab equipment, at its own factory in Ambala, India.

Specifications

What Is the Electromagnetic Spectrum Chart Used For?

We live in a sea of waves we cannot see, and this chart gives teachers one reference for walking a class from long radio waves to short gamma rays. Because the wavelength and frequency scales sit side by side, learners can see that as one increases the other decreases, which leads naturally into the wave equation. It is a useful wall reference for school physics lab equipment in India, from secondary science to senior physics.

The chart also frames everyday questions: how radio and microwaves are put to use, and why X-rays and gamma rays are absorbed differently by different materials. Mount it at eye level near the demonstration bench, keep it out of direct sunlight to limit fading, and use the explanatory sheet to plan discussion questions before the lesson.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the original equipment manufacturer (OEM) behind this chart.
