The MR2 (RTD350) retractor likewise opens under the pressure of the cleaning medium, but is actively closed with air or gas and held closed at around 2 bar – a design that provides particularly reliable sealing during production.
Like the MR1, it can be combined with the Torus, Chemidisc 25-360° and Chemidisc 75-360° rotors, and is rated for ambient temperatures up to 140 °C (30 minutes).
Vorteile
- Defined closing pressure for reliable sealing
- Flexible rotor fitting
- High ambient temperature resistance
- FDA-compliant materials
