    • Q:


      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?

        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?
