This vacuum adapter is made of PTFE with O-ring made of FKM for secure placement of standard filter cartridges made of glass or plastic on vessels and round flasks with ground joint.

• Lateral step-type solenoid made of PTFE
• Chemical resistance
• Temperature resistance from –15 to +200 °C

For vacuum filtration, the O-ring at the passageway seals the connection to the filter slide so that even a small vacuum is sufficient.
