ActionsBioPulverizer
The Bio-Pulverizer reduces tissue hard-frozen in liquid nitrogen to a fine powder. Called freeze-fracturing, this method is especially useful for tough, fibrous tissues such as skin, cartilage, cornea, etc. The Bio-Pulverizer consists of a hole machined in a stainless steel base, into which fits a special piston. In a typical procedure, up to 10g of animal or plant tissue is hard-frozen in liquid nitrogen and placed in the pre-chilled Bio-Pulverizer. The piston is mounted on an easy to use trigger mechanism that is squeezed to deliver a blow to the brittle tissue reducing it to a fine powder. Freeze fracturing with the Bio-Pulverizer is also useful for extracting labile tissue metabolites and as a preliminary step to other homogenization techniques. 2 year warranty
How the Bio-Pulverizer Works
- Place the Bio-Pulverizer in the insulated container and cool thoroughly with either liquid nitrogen (preferred) or a dry-ice/alcohol mixture.
- Place pre-frozen tissue in the well of the mortar. Re-insert the pestle into the well.
- Remove the mortar from the insulated container and pulverize the tissue with one or two blows to the pestle.
- Invert the mortar and empty the powdered contents for subsequent homogenization or extraction procedure.
