CS2 Sterile Tissue Grinders are the same as the CS1 grinders but with a vitrified tip for more aggressive grinding of difficult samples. The proprietary silica casting process results in a glass-like abrasive tip surface that makes it easier to homogenize fibrous samples. The closed system design allows for grinding to take place within a sealed container. Each grinder comes with a fully assembled pestle, a conical sample tube with solid top cap, an adhesive identification label and an instruction card. All are gamma sterilized in easy-open Tyvek® packs. Tubes are made of PP, pestles are 30% glass-filled PP, caps are HDPE and vitrified tips are cast silica.
