Pressure vessel P24D, heavy wall*, with inner tube, protective covering

Heavy wall inner tube has a 4mm hole at die side wall. When the inner tube is pressed down, the interior of pressure vessel connects with its exterior. When the inner tube is lifted up, the insede and outside disconnect with each other. 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 EP 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.
