application:?Drilling tubing connection holes in PDMS devices.
Reusable Biopsy Punchers : These punchers are limited reusable, disposable drilling tools, with a razor sharp stainless steel cutting tip ideal cutting and drilling clean holes in PDMS chip to enable tubing to chip connection. The tip is protected by a cover cap. They may be disposed of after use or cleaned and reused.
You may check the OD of the element (tubing, steel coupler) you will use to connect to your chip.
