General description
Ultrafree®-CL Centrifugal Filter is a single-use, disposable filter used for removing particulates from aqueous biological solutions. Ultrafree-CL devices are available with polyvinylidene fluoride (PVDF) and polytetrafluoroethylene (PTFE) microporous membranes. Many factors can influence nonspecific protein binding, including membrane material, solution pH, buffer strength, contact time, surface tension of the solution, solute concentration, and individual protein character. Durapore® PVDF membrane displays the lowest protein binding of any of the microfiltration membranes.
Application
Ultrafree®-CL Centrifugal Filter has been used in the preparation of lanthanide yttrium orthovanadate nanophosphor (LN)-prepolymer mixtures.
