Mixed Cellulose Ester Membrane Filter, Hydrophilic, White, Non-sterile, Gridded, Plain Discs, 0,45 μm, 50 mm, 100 pcs/pack
Article no.: MCE04550BC
Mixed cellulose ester membrane filters are one of the most widely used filters in both air monitoring and analytical applications.
Depending on your application and need, a mixed cellulose ester membrane filter from our selection will provide the quality and results you need.
Standard Features
Made of a blend of cellulose nitrate and cellulose acetate, hydrophilic
High flow rate and high non-specific adsorption
High mechanical stability
Ideal for gravimetrical measurements, constant weight
Extractables with water less than 1% to ensure sample purity
Suitable for aqueous solutions (pH 4-8), hydrocarbons and some dilute solvents
Adsorption: 160 μg/cm² for γ−globulin and pore size 0,2 μm (decreases with increasing pore size)
Sterilisation: by autoclaving at 121ºC, γ-radiation (25 kGy) or with ethylene oxide
Temperature-resistant up to 180ºC
Applications
+ The membranes with a pore size of 0,45 μm are used for micro-organism counts (microbiological analysis)
+ Sterilisation of solutions and culture media (0,2 μm) – Keep in mind binding of proteins!
+ Pre-filtration, clarification, sterilisation prior to further analysis (0,45 μm)
+ Gravimetrical measurements, removal of particles in suspensions to determine the degree of impurity (sewage plants etc.)
+ Membranes with larger pore sizes (8 µm, 5 µm and 3 µm) are used for chemotaxis and retention of large cells
+ Gridded membranes for counts of colonies as a standard method of quantification
