Chemglass Vial Cap GL-32 with 22 mm Aperture Autoclavable Total of 36 Caps

The Chemglass CG-195-04 Vial Cap is a specialized laboratory closure designed for use with vials or bottles that have a GL-32 screw thread finish. The "GL" threading is a widely recognized standard in laboratory glassware, ensuring a secure, reliable, and leak-proof seal.

A key feature of this cap is its 22 mm aperture (opening). This large central hole is designed to accommodate various components, such as a large diameter septa, tubing, or a probe, allowing for access to the container's contents without having to fully remove the cap. The cap is constructed from a material that is autoclavable, meaning it can withstand the high temperatures and pressures of an autoclave, which is crucial for maintaining sterility and enabling reuse in aseptic applications.

This Chemglass vial cap is a versatile accessory for laboratory procedures requiring a secure, autoclavable closure with ports for sample access, making it useful in applications ranging from sterile media storage to chemical synthesis.
