    • Q:

      hi,

      I am currently using this kind of tube to separate solids by centrifugation. Is there an advised tool to clean the tube without damaging the inside surface of the tube?

        A:

        Brush set, part number 84552-00, is made of foam as to not risk the chance of scratching the glass with any metal parts. In this set there is also a long thin brush that will work well for cleaning out the tip.

    Comments about Conical-Bottom Glass Centrifuge Tubes, 100 mL, for Oil Testing:

    The weight of these use to be 65-75 grams, now they are 40-45 grams (less glass). They seem to break easier now. Weight down but price the same?
