Polypropylene hollow fiber membrane. Outher diameter around 310µm.

Polypropylene hollow fiber membrane. Outher diameter around 310µm. P60 treated with surfactant, pre-primered. Surfactant will flush out.

Small housed luer lock module. Dead end or 2 lumen ports and one open shell port.

Cross flow, 4 port housed hollow fiber membrane module. Glued PVCu housing.

Dead end, inside / out filtration hollow fiber membrane module. Flow direction is indicated on the housing. It is possible to back flush. Intended for lab use, luer lock connections. Must be connected to hose.

Stainless steel housing with cartridge design.

Lab Rord Module is compatible with most of the desk-top bioreactors (fermenters) such as BioFlo from Eppendorf. Shape of a rod (usually d20 or d12mm) allows o-ring seal and easy positioning in bioreactor. Dead end hollow fiber membrane setup is used. Port connection usually hose barb trough thread.

Small immersed hollow fiber module for MBR/sludge sampling. Dead end filtration and weighted bottom of the module makes for easy operation. Standard P60 membrame is used, it is neceseary to wet the membrane before use. It is sensible to mechanicaly secure the module before submerging.

Frame 5RT consists of 5 hollow fiber membrane budles glued in a filtration frame suitable for MBR and industry submersible applications. Membrane used can be P60 or surface treated P6S (not suitable for lab work as surfactnat will leach out). Frame modules can be easily stacked in to a larger membrane units.
