Spex CertiPrep 2000 grinder
The Spex CertiPrep 2000 features a unique vigorous up-and-down grinding/pulverizing action that prepares plant material such as seeds, stems, roots, leaves, and certain animal tissue. Sample preparation is completed in about two minutes with the addition of 1-2 grinding balls to the sample along with a buffer solution. The Spex CertiPrep 2000 handles two standard deep-well titer plates (5 in. long x 3 in. wide x 2 in. high) and can accommodate height adjustment spacers to handle titer plates, racks, vials, and other configurations of up to 2 1/4 inches in height. A digital timer displays both the full timer setting along with the minutes and seconds remaining in the grinding cycle while an adjustable dial allows the operator to set the precise vertical grinding speed between 500 and 2000 strokes per minute.
All of our equipment is used and reconditioned. Our technicians test ovens using a calibrated digital chart recorder to verify the accuracy of temperature controls and readouts and run the unit under vacuum to insure chamber integrity. We typically leave an oven under vacuum for 24 hours to make sure the pressure holds. We replace any hardware or parts as is necessary and clean all incubators thoroughly prior to shipment.
