Product Description
When the goal is to break cells open while keeping nuclei intact, a Dounce grinder is the standard tool. Each complete unit includes two glass pestles, letting you reduce the sample with the first and then form a fine, consistent homogenate with the second.
This listing is for Kimble catalog number 885301-0040: Replacement Large Clearance Pestle (with handle) for KONTES Dounce Tissue Grinder, 40 mL. The grinder is all borosilicate glass 3.3. The large clearance pestle handles initial sample reduction, and the small clearance pestle produces the final homogenate. The 0.5 mL and 1 mL pestles have no handles. Complete sets come in sizes from 0.5 to 100 mL, and replacement pestles and tubes are fully interchangeable. LIGHT LABS supplies the complete DWK Life Sciences line, including Kimble, Wheaton and DURAN labware.
