Description:

These high-quality, black rubber conical stoppers (size 19) are ideal for sealing flasks, test tubes, jars, and other laboratory glassware. Perfectly suited for flasks with a 22mm diameter, these stoppers offer a reliable and secure seal. Each stopper measures 30mm in height, with a 23mm base and a 17mm small diameter. The mid-diameter is 19mm.

Manufactured from a thermally and chemically resistant rubber compound (GOST 7852-76, 23-6-3), these stoppers withstand temperatures ranging from -8°C to +80°C.
