Replace syringe-coupled devices with single filter units for one-time use. Often used for removing particulates from potentially hazardous samples. Pour or pipet sample into filter barrel, insert plunger and compress to filter into autosampler vial.
Preassembled units consist of a filter barrel and a plunger
Built-in air purge minimizes holdup
Integrated construction eliminates filter pop-off
Support stand protects slip-Luer tip, recessed to reduce chance of contamination
Handle samples up to 12mL in volume
All have an integral 25mm diameter filter in barrel (graduated in 1mL intervals) with polyethylene plunger
Filtration area: 3.0cm2
Glass microfiber prefilter ensures higher flow with less clogging
Units with NYL, PTFE, and PVDF membranes are available sterile
Cellulose Acetate (CA)
Low nonspecific protein binding, high loading capacity; for biologicals
Glass Microfiber (GMF)
High loading capacity, binder-free, fast flowrates; for clarifying aqueous or organic solutions, pH 3 to 8
Inherently hydrophilic; for clarifying aqueous and organic samples, pH 3 to 10
For aqueous and organic solutions; ideal for aggressive samples and high debris
