RCT Reichelt Chemietechnik

Membrane filters form the core of modern separation technology and enable precise filtration of the smallest particles through specially developed filter membranes. This filtration technology uses thin, porous membranes that selectively retain solid particles or colloidal particles depending on pore size, while allowing solvents and dissolved substances to pass through.

Material diversity for different applications:

• Filter section made of PVC
• Filter plate made of PVC
• Filter disc made of PVC
• Capillary pore membrane made of polycarbonate
• Membrane made of cellulose mixed ester
• Membrane made of cellulose acetate
• Membrane made of cellulose nitrate
• Membrane made of regenerated cellulose
• Polymer membrane section
• Polymer membrane disc
• Round filter made of glass fiber
• Round filter made of PES
• Round filter made of PSU
• Round filter made of PTFE
• Round filter made of PTFE - stretched
• Round filter made of PTFE - sintered
• Round filter made of PVDF - hydrophilic
• Round filter made of PVDF - hydrophobic
• Round filter made of silver
• ZITEX® round filter made of PTFE

Technical specifications:
Available membrane diameters include 13 mm, 25 mm, 47 mm, 50 mm, 76 mm, 90 mm, and 142 mm. Pore sizes are finely graduated from 0.015 µm to 12.0 µm, covering the entire spectrum of microfiltration.

Application-specific pore size:
Membranes with 0.015-0.1 µm are suitable for virus and protein filtration, while 0.2 µm filters are used for sterile filtration and 0.4-1.0 µm filters for biological determinations and cell separation. Larger pore sizes up to 12.0 µm serve as prefilters and for general cleaning tasks.

High-performance materials:
PTFE (polytetrafluoroethylene) and PVDF (polyvinylidene fluoride) membranes offer exceptional chemical resistance and temperature stability up to +260°C. These fluoroplastic membranes are particularly suitable for aggressive media and high-temperature applications.

Versatile applications:
Membrane filtration finds application in laboratory technology, biotechnology, clinical biochemistry, research, and industrial production. From virus filtration through sterile filtration to gravimetric analysis, the various membrane types cover all requirements of modern separation technology.
