Crucible Tongs are specialized metal tools designed for safely handling hot crucibles, evaporating dishes, and other laboratory apparatus exposed to high temperatures. Made from durable, heat-resistant metals such as stainless steel or nickel-plated steel, these tongs provide a firm grip, ensuring the safe transfer of heated items during laboratory procedures, including heating, melting, and chemical reactions.
Daniel cell
The Daniel Cell is a classic electrochemical cell consisting of zinc and copper electrodes immersed in their respective sulfate solutions and connected by a salt bridge. It generates electrical energy through redox reactions and is used primarily for educational and laboratory demonstrations in electrochemistry.
Demonstration transformer
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.
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.
Leslie cubes
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.
