Rubber Stoppers

With a high material purity, rubber stoppers and bungs are lightweight options to seal containers or apparatuses. Solid styles do not permit any gas exchange in order to protect ultra-sensitive contents, while holed options support unexposed processing. Retaining the characteristic softness even under testing conditions, solid rubber stoppers are often autoclavable for repeated use. The inserting closures are available in any diameter size to securely fit any desired equipment including test tubes.
