Polydisc GW for ground water sampling
Whatman™ Polydisc GW’s large filter surface, durable nylon Whatman™ membrane, and quartz fiber prefilter result in high dirt-loading capacity. The filter was designed in line with regulato ry requirements for groundwater testing found in US EPA Method 3005A.
Certified for heavy metal analysis
Heavy metal testing in ground water often requires an aqueous filter to reduce a sample’s turbidity, but results can be skewed if the filter itself contains heavy metals. Cytiva certifies each Polydisc GW batch for low background values for the determination of trace elements.
