Collecting biopsy samples from rare or endangered species is often expensive, stressful for animals, and prone to failure. Missed or repeated attempts waste valuable time, money, and research opportunities — while increasing the risk of injury and contamination.
The TissueGrab™ Biopsy Dart is a patented, gamma-irradiated, single-use device designed to acquire ~1.5 cm³ tissue samples reliably on the first attempt. Built from medical-grade nylon composite, it eliminates many of the shortcomings of traditional metal biopsy devices — including rust, dulling, contamination, and repeat strikes.
Key Benefits:
Pre-assembled dart tip and base can be separated after sample acquisition or immediately bagged and frozen intact.
The TissueGrab™ Biopsy Dart is engineered by fisheries biologists for performance, safety, and ease of use.
