Ripple Tank – Premium Model (Product Code: SLE/PHY/127) is a projection-type ripple tank used to display wave propagation phenomena on a screen for whole-class demonstrations of the general properties of waves. Its frequency is set from 30 Hz to 100 Hz in 0.01 steps, and a 12V, 5A DC power supply is included, with everything housed in a lightweight aluminium case. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the Premium Ripple Tank Used For?

Projecting the waves onto a screen means the whole class sees the same enlarged pattern at once, which is why this model suits lecture rooms and large demonstration benches. Teachers use it to show reflection, refraction, diffraction and interference in turn, following the experiments set out in the manual that accompanies the tank.

The fine frequency control, in 0.01 steps between 30 Hz and 100 Hz, lets you hold a pattern steady or change the wavelength gradually while students take notes. Darken the room for the sharpest projection and allow a moment after each frequency change for the pattern to settle. For a physics demonstration kit on waves, set-up stays simple because the power supply travels in the same case.

It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the High Tension Power Supply Used For?

Thermionic tubes need two things at once: a low heater voltage to warm the cathode so it emits electrons, and a high anode voltage to accelerate those electrons into a visible beam. The High Tension Power Supply provides both from one unit, with its 6.3V AC heater outputs and adjustable 0-350V HT output, which is why it suits fine beam tube work such as the specific charge of the electron experiment.

It also serves other experiments that need a high tension supply, including ionization current studies. Always switch off and turn the voltage controls to zero before changing connections, use shrouded 4 mm leads, and connect the independent earth terminal where the experiment requires it. The voltages involved are hazardous, so the unit should be used under a teacher's supervision.

Joulemeter, Student Digital (Product Code: SLE/PHY/129) is a digital energy meter used to measure the electrical energy delivered to a load in school and college heat and electricity practicals. Designed specifically for student use, it reads from 1 joule to 999,999 joules with 3% accuracy (1% typical) and has a built-in timer that starts and stops with the measurement. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the Student Digital Joulemeter Used For?

The Student Joulemeter sits between a low-voltage supply and the load, so students read the energy transferred directly instead of combining separate voltmeter, ammeter and stopwatch readings. It is most often used with an immersion heater in a metal block or calorimeter to find specific heat capacity, and for comparing the energy used by lamps, small motors and heaters.

Because one press of the start button powers the load and starts both the timer and the energy count, and the stop button cuts the power again, every group's readings begin and end at the same moment. Keep the input within 15V AC or 21V DC and the load current below 10A. That combination makes it a practical digital measuring instrument for calorimeter lab work.

Supplier

Jain Scientific Equipments Private Limited, trading as ScienceLab, supplies the Joulemeter, Student Digital from Ambala, Haryana to schools, colleges and institutions in India and international markets. It is a sourced electronic meter, and we can combine it in one order with heaters, calorimeters and power supplies from our physics list. For vendor registration and export documents, the supplying company's details are GSTIN 06AAECJ8618A1ZT and Importer-Exporter Code AAECJ8618A (DGFT). Visit our company profile for more.

The Joulemeter, Student Digital runs from a 9V DC mains adaptor, which is included. Inside, a microprocessor combined with a precision voltage multiplier calculates the energy, and results appear on a 2 x 16 character LCD.

How does the built-in timer on the Student Joulemeter work?
On the Joulemeter, Student Digital, the start button starts the timer and joulemeter together and powers up the load. The stop button stops both and disconnects input power from the load, so energy and time are recorded over exactly the same period.

Who supplies the Joulemeter, Student Digital?
The Joulemeter, Student Digital is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. The company sources this meter and ships it with other physics items to buyers in India and international markets.

Is a calibration certificate available for the Student Joulemeter?

Ball & Ring Apparatus (Product Code: SLE/PHY/134) is a two-piece thermal expansion demonstrator used to show that a heated metal ball will no longer pass through a ring it cleared when cold, in school and college physics laboratories. Its brass ball, 22 mm in diameter, and brass ring each sit on a brass rod with a wooden handle, so they can be held safely over a flame. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Ball and Ring Apparatus Used For?

The ball and ring apparatus gives a quick, visible proof that solids expand when heated. At room temperature the ball slips through the ring; the teacher then warms the ball in a Bunsen or spirit-lamp flame and tries again, and this time the ball rests on the ring instead of dropping through. As it cools, it falls through once more, which shows contraction on cooling as well.

A second run, heating the ring instead of the ball, lets students test their prediction of what happens to a hole when the metal around it expands. This makes it a staple of school physics lab equipment in India for the heat chapter. Hold the parts only by the wooden handles, rest the hot brass on a heat-proof mat, and let it cool in air rather than quenching it.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM (original equipment manufacturer) of this Ball & Ring Apparatus. It is made and assembled at the company's own licensed factory at Saha, Ambala, Haryana, India, rather than bought in from a trader, and goes factory-direct to schools, colleges, dealers and importers in India and international markets. Repeat orders and replacement parts are handled by the manufacturer itself, so ask us about availability. More background is on the ScienceLab company profile.

Related Physics Lab Equipment

These items are used alongside the ball and ring in heat and expansion lessons:

• Bar & Gauge Apparatus — shows the same effect with an iron bar tested against a brass gauge.
• Bimetallic Strip — shows that brass and steel expand by different amounts.
• Gravesand Ring-Device to Demonstrate Thermal Expansion — an alternative ring-type expansion demonstrator.
• Bunsen Burner — the usual heat source for warming the ball or the ring.
• Expansion Of Liquids Apparatus — extends the lesson from solids to liquids.

See the complete Physics Lab Equipment range for more heat apparatus.

Frequently Asked Questions

What does the Ball & Ring Apparatus include?
The Ball & Ring Apparatus is a two-piece set: a brass ball 22 mm in diameter and a brass ring, each mounted individually on its own brass rod with a wooden handle. A flame source such as a Bunsen burner is not part of the set and is ordered separately.

How does the Ball & Ring Apparatus demonstrate thermal expansion?
With the Ball & Ring Apparatus, students first pass the cold ball through the ring, then heat the ball in a flame and try again. The expanded ball no longer passes through, and once it cools it slips through again, showing both expansion and contraction of a solid.

Why do the Ball & Ring Apparatus parts have wooden handles?
The wooden handles on the Ball & Ring Apparatus keep hands away from the hot brass, because wood conducts heat far less than metal. Students can hold the ball and ring over a flame and bring them together without touching the heated parts.

Who manufactures the Ball & Ring Apparatus?
The Ball & Ring Apparatus is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM, at its own licensed factory at Saha, Ambala, Haryana, India. Schools, colleges and dealers buy it factory-direct, with quotations and repeat orders handled by the manufacturer.

Is a calibration certificate available for the Ball & Ring Apparatus?
The Ball & Ring Apparatus is a qualitative demonstration piece rather than a measuring instrument, so it is not normally calibrated. If your tender asks for any test or inspection document, please discuss it with us through the contact page before ordering.

What should a quotation request for the Ball & Ring Apparatus include?
For a Ball & Ring Apparatus quotation, give the product code SLE/PHY/134, the number of sets, your delivery address and whether you also need burners or other expansion apparatus. The quotation then covers everything for your heat practicals in one reply.

Can the Ball & Ring Apparatus be supplied in bulk for export?
Yes, the Ball & Ring Apparatus can be supplied in quantity to school networks, dealers and importers in India and international markets. Share the quantity and destination through the enquiry cart or contact page, and packing and shipping details are confirmed in the quotation.
