Silicon Rubber Cork (27,21)

Product Description

Silicon Rubber Bung for sealing laboratory glassware, flasks, vials, or test tubes. These protectors are made of high-quality silicone rubber, and they are flexible and won’t easily deform. They can be used as a wine saver for oil, vinegar, wine, beer, etc., and have strong heat insulation and chemical resistance.

Silicone rubber corks are reusable for a very long time in the lab and prevent contamination, providing a better seal than rubber or cork against vacuum and pressure.

These stoppers measure (29,23), (27,21), (24,18), and (22,17) and are ideal for many different types of laboratory glassware while fitting a wide variety of setups.
