Ready-to-use (RTU) glass fiber filters for solids

Solids testing, a key measurement in water quality and wastewater analysis, includes testing for total solids (TS), total dissolved solids (TDS), total suspended solids (TSS) and volatile suspended solids (VSS). It can be challenging for a lab staff to maintain accuracy and daily productivity under time pressure. WhatmanTM RTU filters help lab staff simplify filter preparation steps in solids measurement, streamlining workflows and saving time.
The RTU series filters are pretreated (washing, drying/ignition and weighing) to ensure weight loss less than 4% or 0.5 mg, whichever is less. 934-AHTM RTU filters meet the requirements of SM2540C/D/E, and GF/CTM RTU filters conform to EN872. The RTU filter family includes an economy range which is washed and dried but not weighed.
