Whatman 934-AH, the most widely used filter for Total Suspended Solids Analysis, is now available in a time-saving, Ready-To-Use (RTU) format. The 934-AH RTU contains the trusted binder-free, high purity borosilicate glass microfiber filter mentioned in Standard Methods.

  • Use the pre–washed, pre–weighed filter immediately—no need to pre–treat
  • Each RTU filter is packaged within an aluminum pan with the filter weight clearly printed on a heat-resistant label
  • Efficient: Superior fine particle retention at high flowrates
  • High loading capacity: Capable of processing very turbid samples
  • High temperature tolerant: Can be used with temperatures up to 550°C

The 934-AH RTU meets the requirements under the latest edition of Standard Methods 2540D for determining total suspended solids in water. It is used for a wide range of water monitoring applications including:

  • Monitoring of rivers, lakes and coastal waters
  • Purified discharge of wastewater treatment plants
  • Monitoring discharge water from industrial plants



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 part
