The 10 µm thin TRAKETCH® PC disc with a diameter of 47 mm is used with pore sizes of 0.2 µm or 0.4 µm.
A typical application in water analysis: a membrane is used as a method to detect legionellae. Because of the precisely defined pores, all legionellae stay on the surface of the membrane. As a result, not only can they be quantified, but they can also be analyzed under a microscope.
In some methods, the membrane is folded in test tubes to carry out further analysis. For this reason, the 10 µm thin TRAKETCH® membrane is preferably used.
