MicroMincer Tissue Press

The MicroMincer is a compact, hand-operated screw press which macerates 0.3 grams or less of soft fresh plant or animal tissue (e.g. muscle, liver, brain, epicotyl and pulpy leaf tissue) without sample loss, heat generation, foaming or aerosol problems. Much of the sample, without added buffer, is pushed through a 250 micron stainless-steel sieve under thousands of pounds force. In the case of plant tissues, fibrous, cellulosic pulp is left behind while cell juice and intracellular products are extruded. The resultant extract can be deposited directly in microtubes. The stainless steel MicroMincer utilizes disposable polypropylene liners. Thus, multiple samples can be quickly processed without a need to clean or risk of contamination between samples. Features Directly macerates small samples of soft tissue (e.g., liver, muscle, brain) - without dilution with added buffers or solvent Simple to operate - no need for compressed gases or high pressure electro-mechanical pumps No heat, foam, or aerosols formed The only parts in contact with the sample are the polypropylene cylinder liner containing a 250 micron stainless steel screen and the rubber piston seal (all disposable) Develops thousands of pounds/square inch to mince the entire sample. No Product is lost Disposable parts eliminate cleanup and contamination between samples
