If the sample is liquid containing solids, use one of the following tools:
– Glass stirrer
– Spoon
– Magnetic stirrer
t Use an appropriate tool for grinding the sample.
Use a disposable sample pan:
t Use only Sartorius disposable sample pans (inner diameter of 90 mm).
Reusing sample pans leads to poor repeatability of results:
– After cleaning, sample residues can still remain on the pan.
– Residues from cleaning agents can evaporate during the next moisture
analysis.
– Scratches and grooves made during cleaning result in damage that forms
points of attack for hot, rising air produced during the drying process
(more pronounced buoyancy).
