Features
Reusable biopsy punches are multi-purpose sampling tools designed with a retractable cutting cannula. They are easy to operate, efficient, safe, fast and precise. WPI's 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.
- Individual sterile packs, limited Reuse
- Tip material: 304 stainless steel
- Sterilization: ETO (ethyline oxide)
Cleaning
Clean tip between each sample extraction by coring blank filter paper.
Rinse with ethanol or spray with compressed air to remove dried artifacts.
Rinse mat with ethanol after each sample extraction.
Applications of reusable biopsy punches
- Electrophysiology—Patch recording (various regions of the specimen can be punched prior to separation).
- Biomedical Pharmacology—Collect samples from the brain neurotransmitters for analyzing the metabolic changes in response to active substances, or skin samples to analyze the response of anti aging medications.
- Anatomy—Sample brain regions for analysis of neurotransmitter concentrations of mRNA levels.
- Forensic Sampling—WPI punches can easily cut, retrieve, store and eject material like skin, gel, films, paint chips and paper.
- Microfluidics—Punch flow inlets in microfluidics chambers molded of PDMS (polydimethylsiloxane).
Surgeons and laboratory technicians use biopsy punches and curettes to remove tissue samples.
