Thick Wall Pressure Vessel is cylindrical thick walled glass, with an internal threaded port and a PTFE thread sealing cap (including a 0-type fluorine rubber ring). When leaving the factory, each pressure test can withstand 5 atmospheres of pressure and can be used for pressurized reactions.

* Thick wall and pressure resistant：high borosilicate thickened glass, pressure resistant and high-temperature resistant.

* PTFE sealing cap：Acid and alkali resistant and various organic solvents. The internal thread of the bottle mouth has good sealing performance.

* High quality glass material：Made from borosilicate glass. The thermal expansion coefficient is only 1/3 of that of ordinary glass, it boasts excellent chemical resistance, High hardness, high transparency, and corrosion resistance.

* Caution：Due to varying conditions, glass vessels cannot be guaranteed against breakage under pressure.Always work behind a safety shield.
