Abstract
Resin: PVC, PC, ABS, PP
Metal: aluminum, stainless
Above are the optional material for the housing of module.
For test modules, resin housing is cheaper. However, the resins listed above are not highly resistant to organic solvents.
If your application is recycling of organic solvent from waste liquid or there will be organic solvent, we would recommend you to use metal-based housing.
Also, for autoclave sterilization (120 ℃), it is reasonable to choose metal or polycarbonate(PC), since PVC and ABS has a lower working temperature.
