Hoffman Voltameter
Original price was: $ 58.16.$ 58.05Current price is: $ 58.05.
Hoffman Voltameter is a specialized laboratory apparatus used to demonstrate and measure the electrolysis of water into hydrogen and oxygen gases. It consists of a central reservoir connected to two vertical graduated gas-collection tubes (electrodes) and is typically made from borosilicate glass for chemical resistance and clarity. Platinum or carbon electrodes are used at the base of each tube to conduct electric current. This apparatus is widely used in chemistry and physics education to visually demonstrate the principles of electrolysis, electrochemical reactions, gas laws, and stoichiometry.

Gas Jar Lid is a specially designed cover used to securely seal gas jars, which are containers used to collect, hold, or measure gases in laboratory experiments. Typically made from chemically resistant materials such as glass or plastic, the gas jar lid ensures a tight seal to prevent gas leakage during chemical reactions, gas collection, or storage. It often features one or more ports or holes to allow insertion of tubes, thermometers, or gas delivery apparatus, facilitating controlled gas flow and measurement. Gas jar lids are essential for safe and efficient gas handling in scientific research and educational laboratories.
Microscope cover slips
Microscope Cover Slips are thin, flat pieces of transparent glass or plastic used in microscopy to cover specimens placed on microscope slides. They serve to protect the specimen from contamination, prevent drying, and provide a uniform thickness for improved optical clarity during examination. Cover slips help to flatten the specimen, ensuring even focus and minimizing distortion under the microscope lens. They are typically made from high-quality borosilicate or soda-lime glass to offer excellent optical transparency and chemical resistance. Available in various sizes and thicknesses, cover slips are essential in biological, medical, and research laboratories for preparing wet mounts, fixed samples, and stained slides. Their use enhances image resolution and protects both the specimen and microscope objective lenses.
Microscope mirror
A Microscope Mirror is an optical accessory used to direct and focus external light onto the specimen being examined under a microscope. Traditionally mounted beneath the microscope stage, the mirror reflects ambient or artificial light upward through the condenser and specimen to illuminate the sample. Microscope mirrors typically have one flat and one concave reflective surface, allowing users to adjust the intensity and focus of the light beam. Made from highly polished glass or metal with reflective coatings, these mirrors are essential in microscopes lacking built-in illumination systems or as backup lighting aids. They enhance visibility, contrast, and detail, making them valuable in educational, medical, and research laboratory settings.
