特點和優勢

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.
  • RTU Double Weigh—drying, cooling and filter paper weighing steps repeated twice for customers with the highest regulatory concern.
  • Economy versions of 934-AH RTU dissolved, suspended, and volatiles testing filters are also available. These filter papers are pre-washed and dried but not weighed and do not come with barcodes.
