The Rama Scientific Glass industries glass stopcock is manufactured from borosilicate glass 3.3, a material chosen for its thermal stability and resistance to corrosive chemicals. This makes the stopcock suitable for controlling fluid and gas flow in laboratory systems where chemical compatibility and leak-free operation are critical. The product is available in multiple configurations, including straight glass, PTFE, and needle valve variants.
Borosilicate glass 3.3 is a standard material for laboratory stopcocks due to its low coefficient of thermal expansion and high durability. The stopcocks are precision-ground to ensure smooth operation and a tight seal, which is essential for maintaining system integrity during experiments. The PTFE variant adds a non-stick, maintenance-free plug, ideal for handling aggressive or viscous substances.
These stopcocks are compatible with standard ground joint glassware and are widely used in distillation, reflux, filtration, and vacuum systems. Buyers in pharmaceutical, chemical, and research laboratories typically source these components for precise flow control. Confirm the exact joint size, material specifications, and compliance certifications directly with Rama Scientific Glass industries, as these details are not fully provided in the listing.
