Batch Cartridge Sizing Calculator

Throughput per cartridge depends on your fluid, so no catalogue can give it for you. Measure capacity on a sample run, then use this calculator to turn that figure into a cartridge count per batch.

How the Calculator Works

StepFormula
Capacity per 10 inL per m² × membrane area per 10 in (0.65 m² or 0.56 m²)
10 in equivalentsbatch volume × (1 + margin ÷ 100) ÷ capacity per 10 in, rounded up
Cartridges at your length10 in equivalents ÷ (length ÷ 10), rounded up

The calculator scales linearly with membrane area, which holds when flow per unit area on the sample run matches production. A prefilter stage ahead of the membrane changes capacity, so measure with the prefilter you will actually run.
