MilliporeSigma™ Durapore™ PVDF Membrane Filters: 0.45μ Pore Size

Description

Recommended when maximum recovery is important. Durapore™ PVDF Membranes: 0.45μ Pore Size provide high flow rates and throughput, low extractables, broad chemical compatibility and low protein binding. Available in diameters ranging from 13mm to 142mm.

• Composed of polyvinylidene fluoride (PVDF) that binds far less protein than than nylon, nitrocellulose or PTFE membranes
• White membranes are autoclavable
• Hydrophilic membranes are 125µm thick with 0.45µm pores
• Typical refractive index: 1.42
• Plain-surfaced filters available in 13, 25, 47, 90 and 142mm, plus a gridded-surface 47mm option

Ideal for use with:

• Clarification of air and other gases
• Sterilizing filtration of protein solutions, tissue culture media, additives, antibiotics and alcohols
• Particulate removal and biological assays (receptor binding studies, TCA precipitates)
