Our 37mm, 0.8 µm (micrometer) membranes are produced in exact accordance with ASTM Research Report D1012 under which they have been granted approval for use in methods D2276 as well as IP216. We manufacture our own plastic monitors using Tenite, a product of Eastman Chemical Co. Our monitors are made to fit all recognized brands of holders including the Gammon MiniMonitor Kit® and the Millipore Corp. XX64-037-30.
Refill membranes are packaged with a blue paper separator between each one to aid in separation.
Matched-weight refill membranes are packaged with each pair in a glassine envelope. Each pair is matched in weight within 100µg (micrograms) in a closely controlled atmosphere.
Support pads are 34mm in diameter so as to fit into the recess of the plastic monitor beneath the membrane.
Matched -weight monitors have yellow plastic plugs in the inlet port and a red plug in the outlet. Single membrane monitors, used for color rating tests, have blue plugs in the inlet and red plugs in the outlet.
