QS11 Operator Notes

•

Sectioning – The recommended blade holder angle for most applications is 10°

•

After each use – Remove any debris from the microtome and cryo-chamber. Especially

clean the blade holder, specimen head and vertical travel areas. A build-up of debris

over time may freeze causing "knocking" or "thumping" during handwheel operation.

•

Periodically – Empty the liquid that accumulates in the plastic container from the defrost

cycles. The container should be periodically disinfected.

•

Defrosting – Due to the extremely low temperature in the cryo-chamber and the window

remaining open for extended periods of time during operation, humidity from the room

will create a frost build-up inside the cryostat. It may be necessary to occasionally turn

the cryostat off and perform a complete defrost of the unit.
