The cross-flow membrane chips have two in- and outlet ports above and below the membrane. This allows for experiments such as small molecule transfer measurements, on-chip dialysis or cell culture experiments. 
 
The chip contain two cavities, each comprising an integrated membrane serving as cell culture area. Cells cultured on the membrane are perfusable independently from both the apical or basal side through upward directed (upper perfusion) and downward directed (lower perfusion) channels.
 
Produced by injection molding with welded membrane of polyethylene terephthalate.
