[RoTrac capillary pore membranes for laboratory filtration. II. Bacteria-free filtration].

Because of their special characteristics Capillary pore membranes (CPM) are now applied in several branches of separation techniques and analytics. Besides applications in particle analytics and microfiltration of different media capillary pore membranes can be used in microorganism separation. It was shown that RoTrac CPM can be used for bacteria free (or so called sterile) filtration.

[RoTrac capillary pore membranes for laboratory filtration. I. Degermination filtration].

RoTrac capillary pore membranes (CPM) are produced by means of the nuclear track technology. Thus a defined and in wide ranges independent adjunction of the different membrane parameters (diameter, density, shape and inclination of pores) is possible. The wanted uniform separation diameter of the membrane can exactly be chosen according to the size of the microorganisms to be rejected.
