Choosing a Crossflow Membrane Test Cell Size: 21, 42 or 140 cm²

At a glance. Tech Inc. makes crossflow cells in three sizes. The 42 cm² Crossflow Membrane Test Cell is the most versatile: enough area for reliable flux, small enough for new materials.

Which size when

• About 21 cm²: new materials where coupons are scarce.

• 42 cm²: routine screening, fouling and teaching.

• 140 cm²: element-like data and low-flux membranes.

What makes a good cell

• Standard feed spacers, so flow matches spiral elements.

• SS316 body for pressures up to 69 bar.

• Good permeate support so the membrane does not deform.
