Membrane filters, non sterile, ReliaDisc™
Filter Membranfilter
These plain white non sterile microfiltration membranes are used to remove particles and microorganisms from various organic solvents and aqueous solutions.

  • Particle retention and collection
  • Sterile filtration of solutions
  • Particulate analysis
  • Air monitoring applications
  • Microbiological analysis of potable and waste waters

Cellulose acetate: Low protein-binding, well suited for sterile filtration and clarification of aqueous solutions in the pH range 4 - 8, nutrient media, buffers, and sera. Also compatible with alcohol and oil. These hydrophilic membranes offer high and consistent flow rates. Maximum thermal stability is 180 °C.

Cellulose nitrate: Set standard in both analytical and microbiological filtration. Available in a wide range of pore size and is well suited for microbial analysis in water, food and beverage application in the pH range 4 - 8. Maximum thermal stability is 130 °C. These membranes are available in a 47 and 50 mm ready-to-use standard size and it supports optimum colony growth.

Regenerated cellulose: Hydrophilic, pH range 3 to 12 and resistant to solvents. Typically used for HPLC sample preparation. Maximum thermal stability is 200 °C.

Nylon (Polyamide): Hydrophilic and widely used in both aqueous in the pH range 3 to 14 and organic solvent filtration applications. Well suited for clarification of buffers and nutrient media with a low level of extractables. Maximum thermal stability is 100 °C.

PTFE: Permanently hydrophobic filter material, very suitable for air and gas particulate filtration. Extremely resistant to aggressive solvents and acids in the pH range 1 to 14. Maximum thermal stability is 200 °C. Must be pre-wetted with ethanol before the filtration of aqueous media.
