Drill bit

Particularly tough tissue types (such as seeds or skin) are not completely disrupted by pulverization with the Cellcrusher.  For such samples,  secondary grinding with the drill-bit accessory is often necessary  This tool can be used with any variable speed drill or electric screwdriver that can hold a 9 mm bit. Fine glass beads (maximun diameter 0.5 mm) are the recommended abrasive.

The drill-bit is also useful for yeast lysis and fungal lysis.  The Cellcrusher can process up to 10 g of cells at a time when used in this manner.
