Biotech Elements
Small Size Spiral-wound Elements for Lab Testing
The Biotech Test product family includes RO, NF, UF and
MF membranes. These small elements are used for trials
when the amount of feed liquid available is limited.
The Biotech Test Elements are made with high temperature stable construction materials. The maximum recommended operating temperature is 50°C (122°F). Operation
at temperature above 50°C (122°F) is possible however
permeability will be reduced by irreversible compaction.
The Biotech Test Elements feature a Durasan* Cage patented Outerwrap, a 34 mil spacer and polysulfone parts.
