RE: S-35 contamination

I have in the past used screw cap epentorff type tubes.  They have an O-ring

and prevent leakage.

  Hi



   I have a problem of contaminating centrifuge in one of our labs.

  In the stage of separation between the glass beads and the extracted

protein

  they use an epentorff vial inside a vial and can't seal it so the result

is

  centrifuge contamination with S-35. Is any one using this procedure??

   How you avoid contamination? Is there a different technique?







Thanks, Rafi Srebro
