Color Rating Membranes and Matched-Weight Membranes

Approved for testing jet fuel per ASTM Methods D2276/IP216 and D5452

Our 37mm, 0.8μm (micrometer) membranes are produced in exact accordance with ASTM Research Report D1012, under which they have been granted approval for use in methods D2276/IP216 as well as Ip216. We manufacture our own plastic monitors using clear Tenite. 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.
