The pump head of the OEM peristaltic pump WPM2 can be autoclaved several times.
Thanks to the housing material polysulfone (PSU) the pump head can be autoclaved up to 30 times. This means that the WPM2 built-in pump can be used in the aseptic area without hesitation.
The WPM2 peristaltic pump is designed for liquids with a temperature of up to 80°C The housing and the front panel of the WPM2 are only available in the transparent colour version.
Properties of the WPM2 pump:
- Pump head is autoclavable
- Flow rate: 0 - 121 ml/min
- Temperature resistant of liquids up to 80°C
Free mounting configuration
A "Free mounting mechanism", which applies a bayonet configuration that is also used in mounting and removing camera lenses, is used in the base. As the cassettes can be mounted and removed manually without using tools, maintenance such as tube replacement can also be performed speedily.
