KIMBLE® KONTES® Sterile Closed-System Tissue Grinder, with Vitrified Tip, 10/Case

• Manufactured from polypropylene (tubes); pestles are 30% glass-filled PP and caps are HDPE
• Sterile Tissue Grinder available with two different tips: molded (closed system 1) and vitrified (closed system 2)
• The proprietary silica casting process in Closed System 2 tissue grinders results in a glass-like abrasive tip surface that makes it easier to homogenize fibrous samples
• Tissues are ground within a sealed container to minimize the risk of personal contact - exposure to sample aerosols is eliminated
• The molded-in abrasive surface on the pestle tip leaves no sediment to obstruct sample examination
• Narrow pestles eliminate the potential of sample overflow common with other types of grinders
• All are gamma-sterilized in easy-open Tyvek packs
• Each grinder comes with a fully assembled pestle, a conical sample tube with solid top cap, an adhesive identification label and an instruction card.

KIMBLE® KONTES® Sterile Closed-System Tissue Grinder, with Vitrified Tip 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.
