  1. Perfect filter product review by TheDoc on 8/7/2016

    Excellent quality and perfect fit on the GL45 bottles. Easy connection for the vacuum hose.

  2. One of the best filters available review by Chem_guy on 10/17/2013

    Love these filters. They are more resilient than any of the others I've tried. They can filter solutions using more powerful solvents, at higher temperatures and pressures than any other filters. They also filter quicker than other brands.

    The only down side I've had with them is getting a good seal on some bottles. But it is an issue I have with many bottle top filters.

  3. Misleading review by Brandon on 9/3/2013

    Filter wouldn't seal to the top of my flask. I have used the exact same filter just different brand that stated 33/45mm fitting neck that perfect. The foam rim where the flask rest again on the bottom of filter want seal off.

  4. not sterile review by hill450 on 5/8/2013

    I purchased these zapcaps thinking they were the sterile ones but they are actually zap cap CR's which state on the package that they are not sterile. Other than that everything else on my order is working well.
