Precise flow control for better filtration efficiency
Infusion filters

Infusion filters are used to reliably prevent particles from entering the human body to prevent life-threatening blood clots or to distribute drugs in a precise and controlled pattern. The filtration / retention rate can be determined by choosing the correct pore size. By selecting the best pore size, customers can determine the retention rate for small particles and determine the flow rate for the infusion solution by correlating the membrane flow rate with the priming pressure of the drug delivery solution.

Because our track-etched membranes have a highly defined pore structure, along with adjustable pore size and flow parameters, they can offer a unique solution for every infusion filter application. In addition, mounting can be done conveniently with ultrasonic welding or other assembly methods
