货品编号： Thermo.88503 品牌：Thermo 品名：Pierce™ Protein Concentrators PES, 规格：100K MWCO,0.5 mL25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.
