2. Total Suspended Solid Determination
Sample (5-10 ml)
Wet the filter with a small volume of reagent-grade
water to seat it.
Minimize the contact of sample to glass funnel
surface.

Heated samples and beakers, or weighing dish, are cooled in a desiccator to prevent the sample or beaker from gathering moisture as it
cools.
If a sample is allowed to cool in the open air of the laboratory, it will absorb water from the air.
This added water weight will give an incorrect measurement. Weighing the sample while it is hot also will cause inaccurate
measurements because as the sample cools, the weight fluctuates.
