Cleaning the Cylinders and the Sampling Chamber
4.2 Cleaning the Cylinders and the Sampling Chamber
Clean the surface of the CASY Instrument regularly using a damp microfiber cloth. It is important to
remove salt solution spillages in the instrument immediately. To do this, raise the sample platform
and remove it by pulling forwards. Use 80% ethanol to remove organic impurities. Under no circum-
stances, however, should other organic solvents be used.
4.3 How to take the CASY Instrument Out of Operation
If your CASY System will not to be operated for several weeks, the fluid system should be drained.
Before shutting down, the fluid system must also be cleaned (see Chapter 4.1,

tine
). Please always follow this procedure to shut down the system:

You must ensure that when the fluid system of the CASY Instrument contains a saline solution, it
is not allowed to dry out. This is very important to prevent malfunction and damage to the fluid
system and valves caused by salt crystals.
