Wheaton® Tapered Tissue Grinder Sets with Glass Pestle

These Wheaton® tapered tissue grinder sets feature a conical surface chamber and an improved design which incorporates a longer tapered surface on both the mortar and pestle. The conical surface allows initial size reduction followed by passage through the cylindrical section for the final homogenization step. Grinding efficiency is improved and less time is required as compared to the Tenbroeck and Potter-Elvehjem designs. When the pestle is "bottomed" within the mortar, the clearance is a uniform .004 to .006-inches (0.1 to 0.15mm). The components are interchangeably ground which allows easier replacement of parts, therefore there is also no need to keep parts matched during cleaning. The ground glass surface on both the mortar and pestle are capable of homogenizing connective tissue including heart, muscle and lung. This unit can also be used for homogenizing skin and plant tissue. Manufactured from Wheaton-33® low extractable borosilicate glass that conforms to ASTM Type I, Class A and USP Type I requirements. Fully autoclavable for sterile homogenizing of tissue.
