Transparent, disposable filter holders made from Tenite® plastic and pre-assembled with MF-Millipore filters (effective filtration area is 9 cm2). A thick cellulose pad, 34 mm diameter, between the monitor sections seals the filter to distribute sample flow evenly over the filter surface. Use with Fluid Sampling Kit (XX64 037 30).
Contamination Analysis Monitors
Monitors have Average Background particle Count (ABC) values marked on each package. Special thick pad supports the filter at high differential pressures.
Matched-Weight Monitors eliminate test filter pre-weighing in gravimetric analysis. Each monitor contains two filters matched in weight to within 0.1 mg. Sample passes through both, but upper (test) filter retains all contaminant. The difference in filter weights, after drying, equals the weight of contaminant in sample.
