Autoclaving The manifold (M) of the Transferpette ® -8/-12 electronic (highlighted in picture) can be autoclaved at 121 °C at a pressure of 2 bar for 20 minutes according to DIN. Note: The handgrip can not be autoclaved! Eject the pipette tips. Unscrew the manifold from the grip.
Servicing and Cleaning The three main components of the manifold can be easily separated and disassembled for servicing, cleaning or replacing parts. The procedures are illustrated on the following pages. Note: The changing of the V-rings/O-rings on the individual nose cones is described in detail in the instructions enclosed with the spare part.
Disassembling the Manifold Removing of nose cones and seals for cleaning or replacing Unscrew the manifold from the handle. Turn both closures of the manifold housing cover 90° and slide off the housing. Push the mounting tool on the nose cone and unscrew it (Fig.
