Grade FVS - Washed, Dried & Weighed Filters:

This paper is fine porosity, fast flow rate, with a 1.5μm size particle retention. Ideally suited for determination of Fixed and Volatile Suspended Solids (FVS).  This material is compliant with the requirements of Standard Method 2540C, 2540D & 2540E and EPA Method 160.2.

Our filters are washed and rinsed under vacuum with three 20mL aliquots of deionized water. The FVS Filters are dried at 105°C in a laboratory oven for 1 hour then placed in a Muffle Furnace at 550°C for at least 15 minutes then cooled and desiccated. The muffle furnace and desiccator steps are repeated for two cycles as per SM2540. The filters are weighed on an analytical balance to the nearest 0.1mg. Then placed in an individual aluminum pan with a barcode label showing the sample number and the weight of the filter.

The box is packaged as a quantity of 100 filters.  Each box has an unique lot number for traceability.
