Microbiological filtration units

Introduction to Microbiological filtration units

Microbiological filtration units are specialized vacuum filtration systems used to capture and retain microorganisms on the membrane surface for laboratory testing and analysis.

When choosing the equipment, users should consider construction materials such as heat-resistant glass with PTFE frit or stainless steel, compatible with 47 mm or 50 mm diameter filter membranes. Funnel capacities include 100 ml, 250 ml, and 500 ml options combined with 1000 ml or 2000 ml flasks with standard NS 45/40 joints, providing flexibility between reusable funnels and disposable plastic funnels such as Biosart 100 Monitors. The catalogue currently features products from German brands Sartorius and Duran; customers can Contact us for detailed configuration advice.

Which brands of microbiological filtration units does Hoa Viet supply?

Hoa Viet currently supplies microbiological and laboratory vacuum filtration systems from two German manufacturers: Sartorius and Duran.

Should I choose a stainless steel or glass microbiological filtration unit?

Stainless steel filtration units are suitable for microbiological testing procedures requiring high mechanical durability and direct flame sterilization. Glass filtration units with PTFE support discs facilitate visual observation of liquid flow and graduation marks during sample filtration.

Which filter funnels are compatible with the Sartorius 1-branch microbiological filtration unit?

The device connects flexibly with 250 ml glass funnels, 100 ml stainless steel funnels using 47 mm or 50 mm filter membranes, and is also compatible with Biosart 100 Monitors disposable plastic filter funnels.

What should be noted when installing a vacuum filtration unit with a PTFE disc and clamp?

The PTFE support disc must be placed flat and flush between the filter funnel and receiver flask before clamping securely to ensure complete vacuum tightness. After filtration, carefully disassemble the clamp to avoid tearing the filter membrane and clean all contact surfaces.
