Electron Microscopy Sciences 5 mL Pestle Only

Electron Microscopy Sciences This is new design grinder with longer tapered surface on both the mortar and pestle, offering grinding more efficient and less time require. The conical surface allows initial size reduction followed by passage through the cylindrical section for the final homogenization step. Made from wheaton 33 low extractable borosilicate glass. Interchangeable components takes the hassle out of matching parts. Unit is autoclavable. When the pestle is "bottomed" within the mortar, the clearance is uniform 0.004" to 0.006” (0.1 to 0.15 mm).
