Products
Linear Expansion
A high-quality apparatus to determine precisely co-efficient of expansion of various metals. An aluminium channel carries a 60 cm long metal rod enclosed in a heating jacket having three nipples for water intake, water outlet and thermometer insertion. Dial indicator is a precision instrument sensitive to 0.01 mm/division and is securely mounted. As the apparatus works with hot water, there is no danger from any steam escaping and causing burns on the skin. Complete with four expansion rods of steel, brass, copper and aluminium.
Hook Weight Set Economy
Black Painted weights have a non-movable hook on the top. Bottoms of the weights are recessed and contain a weight below bar allowing weights to be hung from each other. Weight set includes one each of 10 gm, 50 gm, 100 gm, 500 gm and 1Kg. Two each of 20 gm & 200 gm. In plastic molded box.
Opisometer
A practical instrument for measuring the length of curved lines with accuracy. It is fitted with a knurled wheel and index mark, mounted on a U-bracket with threaded spindle, and supported by a rear handle for ease of use. The length is determined by multiplying the number of wheel rotations by the wheel’s circumference.
Highlights:
Refraction & Reflection Tank
A versatile optical apparatus designed for studying reflection and refraction of light. The apparatus is mounted on a stable base with a circular protractor and pointer for precise angular readings. Supplied with a semicircular acrylic block, prism, and mirror, it enables students to explore core concepts such as Snell’s law, total internal reflection, critical angle, and light behavior through various media. Perfect for hands-on optics experiments in schools and colleges.
Features :
Newton Colour Disc with Adjustable Clamp
The Newton Colour Disc with Adjustable Clamp is a simple yet effective tool to demonstrate the principle of color mixing. When rotated, the colored segments blend together, visually illustrating how primary colors combine to form white light. Its adjustable clamp allows easy attachment to stands, making it convenient for demonstrations and experiments.
Features:
Swivel stand for bar magnet
This swivel stand provides a stable and convenient setup for holding bar magnets during experiments. It allows free rotation of the magnet to demonstrate magnetic alignment and directional behavior with high accuracy. Designed with durability and smooth pivoting action, this stand is ideal for studying the Earth’s magnetic field, magnet polarity, and related demonstrations.
Features:
Electromagnetic Field Apparatus
This apparatus demonstrates how current produces magnetic fields using three conductor setups: straight wire, single loop, and solenoid – mounted on a clear Perspex frame which enables it for overhead use for demonstration to a group of students.
Highlights:
Motor Model Set
This DC Motor Model Set is designed to clearly demonstrate the construction and working principle of a direct current motor. The unit includes a coil wound armature, commutator, and brush assembly mounted between strong permanent magnets. All parts are mounted on a durable base with terminals for easy external DC supply connection. Operating on 1.5–6 volts DC, this model provides a safe, visual, and hands-on way to understand motor action, electromagnetic force, and energy conversion from electrical to mechanical form.
Features:
Mounted Lamp
Mounted lamp unit with socket and bulb, fitted on an insulated base with 4 mm terminals for external connection. Operates on low voltage DC supply and is suitable for use in circuit experiments and demonstrations.
