Quartz Filter

ACCUSCIENCE offers a binder-free high purity quartz microfiber filter intended for airborne particulate monitoring in high temperatures and aggressive atmospheres. Grade MK 5 has temperature resistance for applications up to 1000°F and contains a low amount of trace elements.

Glass 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
