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.
Mortar and pestle
Mortar and Pestle is a traditional laboratory apparatus consisting of a bowl (mortar) and a heavy club-shaped tool (pestle) used to manually grind, crush, and mix solid substances into fine powders or pastes. Made from durable materials such as ceramic, glass, porcelain, or stone, this tool facilitates the preparation of samples for chemical analysis, pharmaceutical compounding, and food laboratory testing. The mortar’s thick walls and the pestle’s sturdy design allow effective pulverization without contamination. Mortar and pestle sets are essential in laboratories for homogenizing powders, breaking down crystals, and preparing reagents and mixtures. Their simplicity and reliability make them a staple in chemistry, biology, pharmacology, and food science labs worldwide.
