① food grade, no additives PP is used, but due to production small amounts of other materials might be used, please consult us for chemical resistance
② VMQ O-ring material is possible
③ ports are prone to brake in case of fall or excess moment, parallel thread – liquid seal or O-rings are preferred choice

Possible Applications

Gas transfer, microporous hollow fiber membrane is used so gas/liquid or liquid/gas
Gas filtration - gas/solids separation on microfiltration level
Membrane degassing - lab, OEM applications

Applications Notes

Ports are plastic, excessive tightening moments and forces will cause breakage. For parallel thread liquid seal (LOCTITE 5331) is preferred, if joint should be often disassembled O-rings are also suitable. Suitable push-in fittings for pipe d6 or d8mm can be supplied.
Try to avoid temperature shocks, slow change is preferable. For contactor (liquid / gas, degassing) applications temperature gradients might cause condensation inside the pores, wetting and module bleeding. When this happens thorough drying (dry air @50°C at least 24 hours) will restore the module.
No oxidizing chemistry or UV light – PP membrane is very sensitive. For chemical cleaning use standard NaOH / citric acid procedure.
Chemical resistance can be estimated from used materials PP, PVCu, polyurethane, usually least resistant is potting - polyurethane.
