Thermo Scientific Orion AQUAfast AQ3010 Turbidity Meter User Guide
Sample vials should always be handled from the top or by the cap to
avoid fingerprints or smudges . After a vial has been filled with a sample
and capped, the outside surface should be wiped with a clean, lint-
free absorbent cloth until it is dry . Cleaned and dried vials should be
stored with the black caps on . The vials can be stored in the carrying
case . During normal operation, you may use any typical laboratory glass
cleaner along with a lint free cloth or tissue to clean the outside of the
vials .
Condensation may appear on the vial when your sample is very cold
and the relative air humidity is high . When this happens, the turbidity
that you read may be higher than the actual turbidity due to the light
scattered by the condensate on the vial . If this occurs, you can alleviate
the problem by either coating the vial with an anti-fogging agent or by
running warm water over the vial for a short period of time to warm the
sample prior to measurement .
