Cellulose Nitrate Membrane Filter, Hydrophilic, White, Sterile, Gridded, Plain Discs, 0,2 μm, 47 mm, 100 pcs/pack
Article no.: NCS02047BC
Cellulose nitrate is the perfect membrane type for water, food and beverage analysis. These membranes are manufactured under strictly controlled conditions.
Depending on your application and need, a cellulose nitrate membrane filter from our selection will provide the quality and results you need.
Standard Features
Made of cellulose nitrate, hydrophilic
High flow rate and high non-specific adsorption
Suitable for aqueous solutions (pH 4-8), hydrocarbons and some diluted solvents
Very uniform pore structure which ensures homogeneous distribution of the particles retained on the filter surface
Extractables with water less than 1%
Adsorption: 160 μg/cm² for γ−globulin and pore 0,2 μm (decreases with increasing pore size)
Temperature-resistant up to 130ºC
Sterilisation: by autoclaving at 121ºC, γ-ra diation (25 kGy) or with ethylene oxide
Applications
+ The membranes with a pore size of 0,45 μm are used for micro-organism counts (microbiological analysis)
+ Membranes with grid lines are ideal for microbiological analyses (bacterial counts) to detect E.coli, coliform bacteria and other germs in water, pharmaceuticals, beverages, cosmetics, etc
+ Sterilisation of solutions and culture media (0,2 μm) - Keep in mind binding of proteins!
+ Pre-filtration, clarification, sterilisation of samples prior to further analysis
+ Removal of particles in suspensions to determine the degree of impurity
+ Measurement of sewage sludge in clarification plants (0.8 μm)
+ Immunological analysis, which allow only a very low level of extractable substance in water
+ Analysis of cell solutions
+ Sterilised membranes are packaged in individual blisters to ensure that the filter is not contaminated
+ Gridded membranes for counts of colonies as a standard method of quantification
