Product Description

Glass MicroFiber Filter 934-AH RTU 47 mm:Our Whatman glass microfiber filter papers in grade 934-AH RTU have been pre-washed, dried (or ignited), cooled, desiccated and weighed, which eliminates the pre-treating steps that are otherwise required by the US EPA Laboratory Standard Method 2540 parts C, D, and E. These glass microfiber filter papers have fine particle retention of 1.5 micro-m at high flow rates to process heavy, turbid samples.

Our Whatman filter papers 934-AH family of products come in three different varieties:

(Most filters come weighed to four decimal places, however a version of the 47 mm glass microfiber filter can be measured to five decimal places if needed.)
  • Ready-to-use for Volatiles pre-washed, pre-weighed and pre-fired at 550 C aligned to US EPA Laboratory Standard Method 2540 parts C, D, and E.
