WHEATON Tissue Grinders enable primary cells to be prepared from excised tissues, as well as subcellular components from harvested cell packs. Tissue grinders are used to extract DNA, RNA and proteins for blots or other procedures. There are a variety of tissue grinders to suit many tissue types. Tapered Tissue Grinders are ideal for connective tissue including heart, muscle and lung. These glass-on-glass grinders feature a long taper design that maximizes grinding efficiency. Potter-Elvehjem Tissue Grinders incorporates a serrated pestle design to disperse homogenate into the mortar cylinder. Standard units with Teflon pestles are well suited for soft tissue, such as brain and liver. Tenbroeck Tissue Grinders have a hollow handle that allows packing with ice, making them suitable for tissue such as liver, intestines and heart. Dounce Tissue Grinders are supplied with two types of pestles: a loose-fitting pestle for sample reduction and a second, tighter pestle for complete homogenization. The ball-shaped pestles leave cell nuclei intact in soft tissues. The WHEATON Micro Tissue Grinder Kit offers a complete selection of micro tissue grinders. All WHEATON tissue grinders are manufactured from WHEATON 33 low extractable borosilicate glass that conforms to USP Type I and ASTM E-438 Type I, Class A requirements and replacement parts can be purchased separately.
