These unique disposable hermetically sealed tubes prevent sample contamination. Each sample tube contains a stirring device, blade, or ball for mixing and homogenizing small samples. Choose from three tube styles with different mixing devices to process your particular sample type.

Ball-Mill Tubes contain a glass ball or ceramic ball for dry milling of dry and brittle samples (e.g. kaolin, gypsum, colored pigments, tablets), cell maceration, and processing of materials mixed with fluids. Process sample volumes from 2 to 15 mL.
