The time required to hand grind samples for DNA extraction can become inhibiting quickly for large projects, but many commercial grinders are too expensive for smaller labs or for limited use in a handful of projects. This tool attaches to any standard Saws-All reciprocating saw and makes short work of many samples. Just install the tube holder, ball bearings, optionally submerge in liquid nitrogen, and pull the trigger!
This idea, originally proposed by Alexander et al. in their paper “Recovery of plant DNA using a reciprocating saw and silica-based columns”, then improved by James Beck of Wichita State University has been optimized by our team for inexpensive production and distribution.
The tissue disruptor is designed to work with the Axygen™ Mini Tube System (MTS118C) and 5/32” ball bearings, though is versatile enough to accommodate many other sample holding systems.
