Why regenerated cellulose?
In addition to versatility, regenerated cellulose filters offer a number of advantages. Unlike polytetrafluoroethylene (PTFE), one of the most commonly used membrane syringe filters today, this hydrophilic membrane does not require pre-wetting. The hydrophilic nature of regenerated cellulose also permits higher flow rates with decreased backpressures, making it easier to process large, multi-point sample runs. And compared with nylon and cellulose acetate membranes, regenerated cellulose filters minimize sample hold-up volumes and maximize recoveries. Regenerated cellulose displays very low non-specific binding and optimizes recoveries, making it ideal for protein or non-protein analytes. Researchers have documented recoveries of up to 98 percent for human serum albumin. These recoveries are higher than that of cellulose acetate, the accepted standard membrane for protein analytes. Sample filtration prevents unnecessary HPLC downtime. And regenerated cellulose filters offer an enhanced
