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.

Absorption Tower
An Absorption Tower is a vertical vessel used in industrial processes to remove specific components from gas streams by contact with a liquid solvent. This equipment facilitates mass transfer between the gas and liquid phases, allowing targeted pollutants or valuable compounds to be absorbed efficiently. Absorption Towers are commonly employed in chemical plants, refineries, and environmental control systems for gas scrubbing, purification, and recovery applications. They are designed for optimal gas-liquid contact, often using packing materials or trays to enhance surface area and improve absorption efficiency.
Bare Enamelled Copper Wire
Bare Enamelled Copper Wire is a high-quality electrical conductor coated with a thin layer of insulating enamel. It is widely used in electrical and electronic applications where insulation and durability are required without adding bulk. The enamel coating provides excellent resistance to heat, abrasion, and chemicals, making it suitable for winding coils, transformers, motors, and inductors. The bare enamelled copper wire ensures efficient conductivity combined with insulation properties, ideal for both laboratory research and industrial manufacturing processes.
Chromatogram Paper
Chromatogram Paper is a specialized high-quality absorbent paper used primarily in chromatography techniques for the separation and analysis of chemical substances.

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.
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.
Plastic Cell Holder
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.
