Harris Uni-Core

Harris Uni-Core

The Harris Uni-Core consists of a razor sharp stainless steel cutting tip designed to cut, retrieve and store cored samples from source materials such as tissue, gels, paper, cloth, leaves, paint chips, films or other thin, soft substrates. The tip is protected by a removable cover cap. Stock sizes are available in a variety of diameters: 0.35 to 8.0mm. The body is made from polypropylene plastic. Each Harris Uni-Core is individually pouched and ethylene oxide sterilized. A 2.5 x 3.0" x 1.5mm thick, inert, self-healing cutting mat with dual cutting surfaces is sold separately. The Uni-Core is a limited reusable, disposable sampling tool, ideal for tissue processing or forensic applications. They may be disposed of after use or cleaned and reused. Cleaning: Clean tip between each sample extraction by coring blank filter paper; rinsing with ethanol or spraying with compressed air to remove dried artifacts. Rinse mat with ethanol after each sample extraction. Autoclave at 20 minutes at 250°F and 15 p.s.i. Recommended autoclave 3 to 5 times.

Operation

Position sample on the Harris self-healing cutting mat (available in two sizes). Remove protective cap from the Harris Uni-Core with gentle twisting. Firmly hold the cutter as shown or in any other comfortable position. The tip is positioned at a right angle above the target area. Use your free hand to hold the mat and material steady while pushing downward into the sample with a semi-circular rotation until the tip passes through the sample. Note: Do not press on the plunger while cutting. Next, lift the cutter away from the sample and the cut sample will be retained in the cutter tip. To eject the cut sample from the tool press on the plunger.

Sample is retained in coring tip following extraction for preferred ejection.

Sample Storage and Ejection

Sample Storage and Ejection

After removing the Harris Uni-Core from the substrate, the extracted sample is stored in the hollow cutting tip ready for preferred ejection. The Harris Uni-Core can be rested on its side without loss of sample from the hollow tip. To eject sample, position tip over target area and depress plunger as shown.
