Made from chemically resistant borosilicate glass, this flask features a round or pear-shaped body with a side arm outlet for vapor to pass through to the condenser. It serves as the container in which liquid mixtures are heated and vaporized, enabling separation based on boiling points. The side arm allows vapors to exit efficiently while minimizing the risk of leaks or contamination. This flask is essential in organic synthesis, chemical purification, and analytical laboratories, facilitating precise and safe distillation operations.
Gas Jar with Lid
Gas Jar with Lid is a durable, chemically resistant container designed for the collection, storage, and measurement of gases in laboratory settings. Typically made from high-quality borosilicate glass or plastic, the gas jar comes with a tight-fitting lid—often equipped with ports or holes—to ensure an airtight seal and facilitate gas transfer or measurement.

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.
