Pre-Filtration | Depth Filtration
Prefiltration | depth filtration by syringe filters, glass fibre (GF) prefilters as well as depth and membrane filters in various materials. The prefilters are suitable for general removal of particles and large microorganisms, such as yeasts and molds. Sartorius Stedim Biotech offers solutions for prefiltration | depth filtration in different pore sizes. Protect your depth filters by the use of prefilters in clarification or sterile filtration applications.
