What is the difference between a 170 micron filter and the Free Lipid Wick?
The filter and the wick are similar in that they both remove an undesirable substance from the blood collected in an Autovac. The 170 micron filter is a screen material with a pore size of approximately 170 microns. This filter removes particles that are larger than 170 microns from the blood as it flows through it. (Note: A red Cell is approximately 8 microns in size.) This filter is a coarse particulate filter. It is intended to be used in conjunction with a microaggregate filter with a pore size of 20-40 microns, typically employed in the infusion set.
