The intuitive touch screen user interface streamlines the test process and the accelerated testing

Fibrous filters like the glass fiber filter shown in Figure 1A consist of a deep mesh of fibers with random orientations. Porous membrane filters, such as those made from mixed cellulose esters (MCE) or polytetrafluoroethylene (PTFE), have a complex structure with tortuous routes through the filter material as shown in Figures 1B and 1C.

Durapore® Membrane Filter, 0.45 µm: Background Information: Durapore® membranes provide high flow rates and throughput, low extractables and broad chemical compatibility. Hydrophlic Durapore® membrane binds far less protein than nylon, nitrocellulose, or PTFE membranes. Features & Benefits

Made from polytetrafluoroethylene (PTFE) bonded to high-density polyethylene Wetting with methanol or another low-surface-tension fluid renders the membrane hydrophilic Mean thickness varies from 145 to 200μm, depending upon filter type

Durapore® Membrane Filter, 0.22 µm: Background Information: Durapore® membranes provide high flow rates and throughput, low extractables and broad chemical compatibility. Hydrophlic Durapore® membrane binds far less protein than nylon, nitrocellulose, or PTFE membranes. Features & Benefits

Pall Acro 50 disposable filters are 0.2 micron rated and contain a Pall hydrophobic PTFE membrane and are ideal for the sterile venting of small containers and as an in-line gas filter. The large effective filter area provides high flow rates and filters can be autoclaved several times ensuring low costs.

DVPP04700. Trade Name. Durapore ®. Description. Durapore® Membrane Filter, 0.65 µm. Background Information. Durapore® membranes provide high flow rates and throughput, low extractables and broad chemical compatibility. Hydrophlic Durapore® membrane binds far less protein than nylon, nitrocellulose, or PTFE membranes. Features & Benefits.

Description. Durapore® Membrane Filters feature high flow rates and throughput, low extractables and broad chemical compatibility. Compared with nylon, nitrocellulose or PTFE membranes, Hydrophilic Durapore membranes have much lower protein binding to minimize interaction with your sample and maximize recovery.
