Maintenance - Thermo Scientific Diluflux Mode D'emploi

4. Maintenance

The Diluflux dilutor requires very little maintenance provided any liquid
leakage was cleaned away thoroughly and quickly after it happened.
Components that are autoclavable: tubing, filter, stopper, bottle
Components that are not autoclavable: unit, pumps
Do not use bleach to clean the housing, the nozzles and the trocar of the
Diluflux dilutor as it may damage the stainless steel.
When cleaning the housing, pay extra attention not to pour liquid inside the
unit especially under the weighing platform. Indeed, liquids could induce
short circuits and damage the electronic boards. Furthermore, continuously
introducing liquids could generate deposits that might block the weighing
cell and cause a lack of sensitivity.
• Daily:
Autoclave the dispensing assembly (when the Diluflux dilutor is used in a
sterile environment).
The whole dispensing assembly can be autoclaved.
• Silicone tubing changing:
If the silicone tube is no longer air-tight, becomes sticky or hard.
• Every 20 autoclavings:
Change the air-filter.
