Sterile filters can be used in a forward (syringe>filter>tube) and backward (tube>filter>syringe) direction to remove microorganisms and particles depending on the chosen pore size. Commonly used filters include Millipore's single use Millex filters.
Pore size
- 0.10 µm - 100 nm
- 0.22 µm - 220 nm
- 0.45 µm - 450 nm
Size comparison
- 0.4-0.6 µm - 400-600 nm Lactobacillus brevi/Listeria innocua width [1]
- 0.7-1.2 µm - 700-1200 nm E. coli width [2]
- 4-6 µm - 4000-6000 nm S. cerevisiae diameter [3])
