  17. Nonsterile A83 NanoGFSyringe Filters, 0.5μm, 25mm, PK100
    Manufacturer: I W Tremont
    HydroBlokr™ functions via use of proprietarily designed, multi-layered series of membranes placed within an ultrasonically welded device which creates a check-valve effect when wet. The functional membrane within the series immediately reacts in presence of aqueous solution by stopping and blocking further passage1 . The materials create a highly retentive pore structure which helps protect the user environment2 . The extraordinarily high flow rates compared to other simple hydrophobic barrier filters creates a high-flow, less restrictive path for vacuum and positive pressure to pass. Unlike simple hydrophobic barrier filters, once HydroBlokr™ is wetted it halts operation and locks out further usage until replaced. No further aspiration is possible, thus helping to protect your sample3 and making it plainly obvious the filter has become wet and replacement is necessary. (100 per PK )
