CHROMATOGRAPHY | Membrane filter
The line of filter membranes includes a wide selection of microfiltration materials with porosity from 0.1µm to 8µm. Typical applications of membrane filters are cell retention, particle collection, clarification and filtration of aqueous solutions, particle analysis, microbiological analysis and epifluorescence microscopy. Membrane types: CA - Cellulose Acetate, NY - Nylon, PTFE - Polytetrafluoroethylene, MCE - Mixed Cellulose Esters, PES - Polyethersulfone, PVDF - Polyvinylidenefluoride, RC - Regenerated Cellulose, CN - Cellulose Nitrate. Sterile and non-sterile.
B.C
Cellulose acetate
Hydrophilic material, offers the lowest protein retention available. High efficiency and lower consumption when filtering protein solutions. Very resistant: ideal for aqueous solutions even very alcoholic and if the recovery of proteins is crucial. Applications: filtration of protein and enzymatic solutions, cold sterilization and cell culture media.
PES
Polyethersulfone
Hydrophilic material, compatible with organic solvents. Applications: water filtration, chemical reagents, high temperature liquids.
NY
Nylon
Hydrophilic material, suitable for aqueous solutions and for use in HPLC. Maintains its structure under normal filtration conditions, eliminating the need for humectants. Autoclavable at 135 ° C. Applications: bacterial and particle removal, filtration of aqueous solutions and organic solvents.
PVDF
Polyvinylidenefluoride
Hydrophobic material, not wettable. It allows the passage of humid air or other gases, even when the pressure differential is very small. Applications: purification of fluids.
PTFE
Polytetrafluoroethylene
Hydrophobic material compatible with aggressive solvents (acids and bases), with a low level of extractables. Used for solvent filtration, HPLC and pre filtration. Applications: filtration of strong acids and aggressive solutions, phase separations, aerosol sampling.
RC
Regenerated cellulose
Hydrophilic and solvent resistant, they are ideal for removing particles from solvents. They are also characterized by a low non-specific adsorption. Applications: purification of fluids, 0.45 for degassing.
MCE
Mixed cellulose esters
Mix of nitrate and cellulose acetate. Hydrophilic, biologically inert. Applications: sterilization of aqueous solutions, particle removal, fluorescence assays, air monitoring.
CN
Cellulose nitrate
It is the standard material for membrane filtration techniques. Often used for particle retention. Applications: checkered sterile for water microbiology with MF technique.
