Combining top-notch and uncompromising quality with an affordable price the Pall Acrodisc Non-Sterile PSF Syringe Filters with GxF/Supor PES Membrane 25mm Case of 200/ 28143-372 can fulfill your laboratory needs while still offering a great value for the money. Product Category Description: These premium syringe filters combine the benefits of a multi-layered prefiltration device with an automation-certified filter housing. The polypropylene housing has been designed to withstand high operating pressures. Some models feature a GxF borosilicate glass prefilter which provides two to four times the throughput of standard glass fiber prefilter devices allowing for quick and easy filtration of difficult-to-filter samples. The GHP hydrophilic polypropylene (GH Polypro) membrane is ideal for maximum chemical compatibility fast flow rates low protein binding and low levels of UV-absorbing extractables. The glass fiber membrane allows for quick and easy filtration for difficult-to-filter aqueous solutions. The Supor (hydrophilic polyethersulfone) membrane is available in a special ion chromatography design or with a GxF prefilter. The hydrophilic nylon membrane has excellent compatibility with esters bases and alcohols and requires no prewetting. The hydrophobic PTFE membrane with polypropylene support offers exceptional chemical and temperature compatiblity and is ideal for gas organic solutions sterile air filtration or venting. Also available are the hydrophilic Versapor (acrylic copolymer on a nonwoven support) and the hydrophilic HT Tuffryn (polysulfone). The Automation Preferred certification assures smooth operation and worry-free performance 24 hours a day in automated workstations. HPLC certified. With female Luer inlet and male slip outlet connections. Ordering Information: Syringe filters packed in cases of 200 are available two ways: in four packs of 50 or in an AutoPack format.
