特點和優勢
Our Whatman filter papers 934-AH family of products come in three different varieties:
- 934-AH RTU for Suspended and Dissolved Solids—pre-washed, dried, cooled, and weighed filters with certified mass loss between washing and drying steps of the lesser of less than 0.5 mg or 4% in accordance with US EPA Lab Standard Method 2540 parts C and D. (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.
