Effects
The following processing chemicals
can result in excessive foaming:
– tenside cleaners containing
detergent and rinse aid.
The foaming can occur:
– in the program block in which the
processing chemical is added,
– in the subsequent program block
due to carry-over,
– in the case of rinsing agents, in the
subsequent program due to
carry-over.
Antifoaming agents, particularly
silicone-based antifoaming agents, can
cause the following:
– deposits in the wash compartment,
– deposits on the wash load,
– damage to the elastomer and plastic
components of the lab washer,
– attack certain plastics (e.g.
polycarbonates, plexiglass, etc.) in
the wash load.

Action
– The process parameters of the wash
program, e.g. metering temperature,
metering concentration, etc. must be
set so that the overall process
creates little or no foam.
– Observe the instructions of the
manufacturer of the processing
chemicals.
– Use antifoaming agents only in
exceptional cases or when they are
absolutely necessary for the process.
– Periodic cleaning of the wash
compartment and accessories
without a load and without an
antifoaming agent using the
ORGANICA program (if available).
