Thermo.88503 Pierce™ Protein Concentrators PES, 100K MWCO, 0.5 mL 25个集中器

     产品描述：
     Thermo Scientific Pierce Protein Concentrators PES are disposable ultrafiltration centrifugal devices with a polyethersulfone (PES) 

     membrane for concentration, desalting and buffer exchange of biological samples. This product has a molecular-weight cutoff of 10K, 

     and can be used for processing sample volumes up to 0.5 mL.

     Features of Pierce Protein Concentrators PES:

     • Rapid protein concentration—sample concentration of 10- to 30-fold can be achieved in 10 minutes or less
     • Excellent protein recovery—unique design minimizes membrane fouling and provides high speed concentrations, even with particle

       laden solutions
     • Instrument-compatible—use standard microcentrifuge with fixed-angle rotors; collect and recover sample without invert spinning
     • Versatile—easy way to perform sample concentration, diafiltration or buffer-exchange of biological samples

     For easy identification, the MWCO value is etched on the side of each device. To assist with sample addition and recovery, a clear window 

     with graduations is located on the side of each device enabling visual determination of the retentate volume. The vertical design of the 

     membrane allows high flux rates, low non-specific binding and negligible protein aggregation on the membrane and provides reliable and 

     consistent results for processing sample volumes between 100 and 500 µL. Typical protein recovery is 90% when the mass of the proteins 

     in the sample is at least two-fold greater than the MWCO of the device used. Sample concentration of 10- to 30-fold can be achieved within 

     10 minutes.
