Our reusable biopsy punches are multi-purpose sampling tools designed with a retractable cutting cannula. They are easy to operate, efficient, safe, fast and precise. Our punches consists of a razor sharp stainless steel cutting tip. It is designed to cut, retrieve and store the cored samples from a source materials. The source could be skin, tissue, gels, paper, cloth, leaves, paint chips, films or other thin, soft substrates. The biopsy punches are recommended as a DNA sampling tool and are also ideal for forensic use and laboratory sampling applications. The punches come sterile and are individually wrapped. They were sterilized using ethylene oxide.

Our biopsy  punches is a limited reusable, disposable sampling tools. They may be disposed of after use or cleaned and reused.

Cleaning

  1. Clean tip between each sample extraction by coring blank filter paper.
  2. Rinse with ethanol or spray with compressed air to remove dried artifacts.
  3. Rinse mat with ethanol after each sample extraction.

Customer comment

"I am using the 0.75 mm WPI punch for punching flow inlets in microfluidics chambers molded of PDMS (polydimethylsiloxane). I have made around 75 hole punches with a single unit into PDMS, the blade and the extractor still work perfectly, though the extractor button sticks slightly. I find the blade to be noticeably sharper than the Harris equivalent, as well as being more ergonomic, in my opinion, with the feel of a pen or pencil in one's hand. " R.P ,UNC
