  • Dounce Tissue Grinder

    DWK Life Sciences (Kimble)

    Produces a relatively coarse homogenate For cellular work where the nucleus remains intact after homogenization All glass construction * Stated clearances for the tubes and pestles are “total” not “annular”.

  • The Dounce type, glass tissue grinder is supplied with two glass pestles; one with a tight inner tolernace and one with a loose inner tolernace. The loose pestle can be used for initial reduction of the tissue sample and the tight pestle can be used to fine grind the tissue and complete the homogenation.
