filters to determine the level of total suspended solids (TSS), dissolved solids or volatile solids.
In addition to the GF/C™ membranes that comply with the EN872 standard, a new Whatman 934-AH™
membrane is available in two versions:
934 AH: complies with the 2540D method - glass fibre 1.5 µm
934 RTU: complies with the 2540D method in a ready-to-use version with a pre-weighed cup and filter
• Practical: pre-washed, pre-weighed, ready-to-use membranes in cups
• Saves time: Rationalisation of the method by removing the membrane preparation steps
• Effective: retention of fine particles at high flow rates
• High loading capacity: capable of handling the most turbid samples
