Q.4. What sample size can be disrupted in the two types of Cellcrusher?

The effective capacity of the standard Cellcrusher is 20 mg – 5 g of tissue.  The capacity of the Cellcrusher-mini is 2 mg to 40 mg.

Q.5. Do I need the drill-bit for my sample types?

The drill-bit is used for very tough, often dry samples that are not fully disrupted by impact pulverization.  Samples that contain water (such as cartilage) are extremely  brittle when frozen with liquid nitrogen and are quickly and effectively disrupted by impact.  Dry samples, such as seeds or bark benefit from grinding with the drill-bit after initial pulverization, because they are less brittle.
