Demonstration transformer
Product Description
The Demonstration Transformer is an educational and laboratory device designed to illustrate the principles of electromagnetic induction, voltage transformation, and mutual inductance. Typically composed of a laminated iron core with interchangeable primary and secondary coils, it allows for hands-on experiments involving step-up and step-down voltage transformation. Ideal for both laboratory demonstrations and industrial training settings, it supports a range of voltage and current inputs and can safely demonstrate real-time transformer behavior using AC power sources.
Double, Triple, Single Lab Pulley
Lab pulleys—available as single, double, or triple configurations—are precision-engineered mechanical devices used in laboratory settings to change the direction of force or lift loads with reduced effort. Typically made from durable materials such as metal alloys or hard plastics, these pulleys consist of grooved wheels that guide ropes or cords smoothly during experiments and mechanical setups. Single pulleys have one wheel, doubles have two, and triples have three wheels, allowing different mechanical advantages depending on the setup. Lab pulleys are essential in physics education, mechanical experiments, and engineering demonstrations where principles of force, tension, and motion are studied.
Equilateral Prism Glass
Equilateral Prism Glass is an optical glass component shaped as a triangular prism with all three sides of equal length. It is used to refract, disperse, or reflect light beams in precise laboratory, educational, and industrial optics applications. Made from high-quality, optically clear glass, the prism offers excellent light transmission and minimal distortion. It is widely used in physics experiments, spectroscopy, and optical instrument calibration. The equilateral prism’s geometry allows it to bend light rays at specific angles, enabling the study of light properties such as dispersion and refraction.
Force Pump
Force Pump is a mechanical device designed to transfer fluids by applying manual force through a piston or plunger mechanism. Unlike lift pumps that only raise liquids to limited heights, force pumps are capable of delivering fluids at higher pressures and over greater vertical distances. Constructed from corrosion-resistant metal or durable plastic, force pumps are widely used in educational demonstrations, physics experiments, and small-scale fluid transfer systems. This apparatus illustrates fundamental hydraulic principles and is essential in laboratories, training workshops, and prototype testing environments.
Glass Rod for Static Electricity
Glass Rod for Static Electricity is a smooth, cylindrical rod made from high-quality glass designed specifically for generating static electricity through friction. Commonly used in physics laboratories and educational demonstrations, this rod serves as a fundamental tool to study electrostatics by producing and transferring electric charges when rubbed with materials like silk or wool. The rod’s chemically resistant, durable glass surface allows repeated use without degradation. It is an essential apparatus for teaching concepts such as charge generation, attraction, repulsion, and the behavior of static electricity in various materials.
Leslie cubes
 Product Description
Leslie Cubes are metal cubes used in physics laboratories to demonstrate the principles of thermal radiation and emissivity. Each face of the cube has a different surface finish—such as polished, blackened, or white—which affects its heat radiation properties. When heated, Leslie Cubes allow students and researchers to observe how surface texture and color influence heat emission, making them essential for studies in thermodynamics and heat transfer.
Linear expansion apparatus
 Product Description
Linear Expansion Apparatus is a laboratory device used to measure the expansion of materials when heated. It helps in studying the thermal expansion properties of solids by precisely quantifying the change in length as temperature varies. Typically made from durable metals and fitted with precise measurement scales or sensors, this apparatus is essential in physics and materials science labs for investigating thermal behavior of materials.
PLASTIC CELL HOLDER
 Product Description
A Plastic Cell Holder is a laboratory accessory used to securely hold electrochemical or dry cells (batteries) in place during physics or electrical experiments. It is typically made from non-conductive, durable plastic and may feature metal terminals or spring-loaded clips for electrical connections. These holders provide a stable and safe platform to integrate batteries into circuits for educational demonstrations, testing setups, or prototyping purposes. Designed for use with common battery sizes (such as D, C, AA, or specialized cells), the holder ensures easy insertion, removal, and reliable connection of power sources without short-circuiting. It is widely used in physics labs, electronics training, and school science kits.
SEMI CICRLE GLASS BLOCK
 Product Description
Semi Circle Glass Block is a precision laboratory apparatus made from high-quality optical glass, designed for experiments involving light refraction, reflection, and optics principles. The semi-circular shape allows for controlled study of how light bends when passing through different media, making it ideal for educational demonstrations and research in physics and optical sciences. The block is crafted from clear, durable glass to provide excellent transparency and minimal distortion. It is widely used in schools, colleges, and research labs for studying Snell’s Law, critical angle, and total internal reflection.
