Universal PTFE stirrer seal
The shaft can be made of any suitable material such as glass, metal or PTFE, as it is not part of the sealing system. It is precisely guided by a glass ball bearing and may be simply axially adjusted.
The stirrer seal can be dismantled and reassembled in seconds without the need for any tools.
