Sterile cellulose acetate syringe filters developed
A range of cellulose acetate syringe filters has been introduced for the life science market.
The SupaTop filters, developed by Anachem, are hydrophilic and low binding. They are suitable for maximum sample recovery for tissue culture media preparation, sterile filtration and clarification of biological fluids, protein and enzyme filtrations, filtration of hybridisation buffers and other aqueous solutions. Due to the hydrophilic nature of the cellulose acetate membrane these syringe filters are designed to sterilise and remove particles from protein rich samples, the company says. They are also recommended for the filtration of probe solutions.
The cellulose acetate membrane is encased in an acrylic housing without the use of any adhesives to eliminate any risk of sample contamination. These filters are available in a variety of pore sizes and are colour coded accordingly for easy identification, 0.2µm (Blue), 0.45µm (Yellow), 0.8µm (Green), 1.2µm (Red) and 5µm (Brown). They are also available in 33mm or 18mm diameters and either sterile or non-sterile.
