Accudisk™ Grade FVS Whatman 934-AH Washed & Dried Filters are 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.  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 inspected and packaged as a quantity of 100 filters per box. 

Other filter sizes are available upon request.  Call, email or write a note on our Contact Us Page.
