Effects of Processing Chemicals

General information
Effects
Damage to elastomer (seals and hoses)
or plastic components of the lab
washer may cause the materials to
swell, shrink, harden or become brittle,
possibly causing cracks to form in the
materials. This will impair their function,
which will generally lead to leaks.
Strong foaming during the program
prevents proper cleaning and rinsing of
the load. Foam escaping from the wash
compartment can result in damage to
the lab washer.
If foaming occurs, the cleaning process
is not standardized and not validated.
Stainless steel corrosion in the wash
compartment and/or accessories may
appear in various ways:
– rust formation (red spots / stains),
– black spots / stains,
– white spots / stains (smooth surface
is slightly corroded).
Corrosion that forms holes can result in
leaks in the lab washer. Depending on
the application, the corrosion may
impair the cleaning and rinsing results
(laboratory analysis) or cause corrosion
of the load (stainless steel).

soils" for more information.
– Find and correct the cause of the
foaming.
– The process must be checked
regularly in order to detect any
foaming.
