KIMBLE® KONTES® Micro DUALL® Tissue Grinder, all-glass, with threaded tube and screw cap, Size 17

  • Manufactured from borosilicate glass 3.3
  • Can serve as a storage vessel following homogenization. Centrifugation, concentrations and lyophillization can be accomplished without a transfer.
  • Flat base allows tube to stand upright without support
  • Heavy wall construction of tube minimizes breakage
  • Capacities shown are without the pestle inserted
  • Supplied complete with pestle, tube, phenolic cap and PTFE liner
  • Replacement components are available and completely interchangeable
  • Clearance between pestles and tubes is 0.004 " to 0.006 "

Product Overview
Tissue grinders produce homogenates by a combination of shearing and compression actions. The tissue sample is progressively ground (sheared) into smaller pieces at the rounded end of the pestle as the spinning pestle is lowered into the tube. As the pestle is forced lower into the tube, the sample is displaced and forced between the straight outside wall of the pestle and the inside wall of the tube, compressing the tissue cells until they rupture. When the tube is pulled away from the pestle, a slight vacuum is created that pulls the sample back past the compression area, resulting in an additional homogenization stroke. The degree of homogenization is controlled by the clearance between the pestle’s and tube’s cylindrical section (radial distance usually 0.002 - 0.003 inches), the rotational speed of the pestle, and the number of compression strokes made. Due to its conical shape this Micro DUALL® Tissue Grinder provides a large surface area of grinding for a micro scale volume. The tube can be used as a storage vessel.
