Pressure vessel P17DF, heavy wall*, flask, protective covering, PTFE coated O-ring

Heavy wall round bottom vessels have an internal thread for use with a 15mm and 25mm PTFE bushing as a pressure seal. This unique design allows hand tightening and loosing for easy access into the vessel. The O-ring is positioned on the bushing above the thread for improved sealing. The vessels are useful for pressure reactions and applications such as polymerization and analysis of halogens by thermal decomposition in the presence of lime. 

The exterior of the pressure vessel is coated with a high-quality coating material, which avoids the risk of the product bursting during the experiment, thus increasing the safety of the experiment. Complete apparatus is supplied with vessel, PTFE bushing and PTFE coasted O-ring.

*Important warnings for pressurized glassware:

Due to varying conditions, we cannot guarantee glass vessels from breakage under pressure. Always work behind a safety shield and due to the characteristics of the coating material, yellowing of the surface may occur after use, but does not affect the use. The coating needs to be used between -40°C and 80°C, too high a temperature will cause the coating to melt.
