Sartorius 11104--90------N Cellulose Acetate Membrane Filters, Circle, 90mm 0.8µm, 100/Pk

Combines high flow rates and thermal stability with very low adsorption characteristics. Sartorius Cellulose Acetate Membrane Filters are excellently suited for use in pressure filtration devices. Non-sterile filters in a variety of diameters and pore sizes are bulk-packed to save money and space.
- Ideal for colony counting, particle testing, microscopy and sterility testing
- High-quality CA membrane filters for use in pressure filtration devices
- Available in pore sizes ranging from 0.2μm up to 5.0μm
- 0.2μm filters are the standard for sterile filtration of aqueous solutions, such as nutrient media, buffers and sera
- 5μm filters can be used as prefilters to retain coarse particles, while allowing microorganisms through.
Can be sterilized by autoclaving at 121°C or 134°C; gamma irradiated to 25 kGy, dry heat or ethvlene oxide.
