Sterlitech
Cellulose Acetate Syringe Filters
Cellulose Acetate membrane is a supported, hydrophilic membrane that is naturally low binding. It is ideal for use in enzyme loading and latex bead entrapment assay formats. These syringe filters are available as sterile or non-sterile and with or without a glass fiber pre-filter.
Features
and Benefits:
- Hydrophilic, low binding filter
- Strength, uniform pore size
Applications
- Sterilize biological fluids, serum or media additives, 3S,
25S, 25SG.
- Sample preparations of aqueous solutions, 3, 17, 30.
- Sample preparation of protein-based HPLC solutions, 3, 17.
- High throughput, low binding filter units for non-sterile aqueous
filtrations, 30.
- Filtrations of tissue culture media, 25SG or 30G.
- High throughput for sterile or non-sterile clarification of
even the most viscous proteinaceous Solutions, 25SG or 30G.
- Filter probe and hybridization solutions to reduce backgrounds,
3S, 25S.
Product
Description
The Sterlitech Cellulose
Acetate syringe filter is well suited for maximum sample recovery
such as tissue culture media preparation, sterile or non-sterile
filtration and clarification of biological fluids, protein and enzyme
filtrations, hybridization buffers, and other aqueous solutions.
The sterile Sterlitech
Cellulose Acetate (S) or with a glass fiber prefilter (SG) is
recommended to filter probe solutions. The Sterlitech Cellulose
Acetate series syringe filters are designed to sterilize and
remove particulates from proteinaceous samples. Due to the
extremely low holdup volume the negligible protein-binding characteristics,
these syringe filter units are ideal for applications requiring
maximum sample recovery from a standard or presterilized syringe
filter.
The membrane filter is
Sterlitech (CA) Cellulose Acetate, which eliminates the possibility
of "popping" the filter. See Sterlitech
(CA) Cellulose Acetate for a detailed description of the membrane
in the filters. The Sterlitech 17G (17mm), 25SG (25mm),
30G (30mm) syringe filters contain a 1.0 micron borosilicate glass
prefilter and the Sterlitech Cellulose Acetate membrane filter
specifically designed to combine high throughputs and maximum sample
recovery when filtering or sterilizing viscous proteineceous solutions.
The prefilter and membrane are contained in the acrylic housing
without adhesives.
The Sterlitech Cellulose
Acetate (S) filters are individually packaged, gamma irradiation
pre-sterilized syringe filters. Other than the 3mm the other
sizes offer bi-directionally support of the membrane allowing sample
injection or aspiration and are individually labeled with pore size
and filter type for quick, easy identification. All units
are tested to verify the filter and housing integrity.
