Glass and Quartz Fiber Filters

Glass and Quartz Fiber FiltersGlass fiber and quartz fiber filters are depth filters that are frequently specified in contamination monitoring methods. Filters made of these materials are available with a variety of flow rates and throughput/dirt-holding capacities. Consequently, some of these filters are also ideal for prefiltration upstream of membrane filters, to prevent downstream clogging.

Our selection of depth filters includes:

  • Type APFF and AP40 glass fiber filters recommended for United States EPA Method 1311 for Toxicity Characteristic Leaching Procedure (TCLP)
  • Type AP40 glass fiber filter recommended for Total Suspended Solids (TSS) Method 2540D
  • Quartz fiber filters (Type AQFA) recommended for United States EPA PM10 ambient air monitoring method.
