HotBlock™: Operation and Instruction Manual Sample Filtration Supplies
FilterMate™ Filtration Systems
Dirty or particulate-laden samples may require that the digested sample be filtered
prior to analysis. This is especially true with sludge, wastewater and soil samples.
FilterMate Systems provide a convenient and inexpensive method of filtration
that requires no transfer steps. The FilterMate fits directly into the digestion cup
and is pushed through the liquid being filtered to the bottom of the cup with a
detachable plunger. After the filtration is complete, the plunger is removed and
discarded while the filter assembly remains in the bottom of the cup.
This arrangement does not interfere with storage or use of the cup in an
autosampler. FilterMates are available with different choices of filters.

Cup Holder for FilterMate Filtrations
This machined HDPE fixture adds stability when performing FilterMate
filtrations. Digestion cup is placed into center hole of FilterMate Holder
prior to beginning filtration. The holder secures the digestion cup as the
FilterMate is depressed through the liquid sample.
