The Lever Tissue Press is a top-of-the-line stainless steel garlic press improved in performance by the addition of a silicone-rubber gasket on the lever press piston.The press efficiently macerates or mechanically disaggregates 5 to 50 grams of fresh, soft plant or animal tissue. By 'soft' we mean nonfibrous tissue. Acceptible examples are muscle, brain, liver, plant fruits, some plant roots and tubers. An extra "can" is included to facilitate processing of multiple samples.
