The star-shaped bottom tube interiors of the immuno-tubes increase the surface area to enhance levels of antigen or antibody binding. Users can select low-, medium-, or high-bind capacity tubes in 4 mL and 5 mL volumes designed for compatibility with standardized equipment. Medium- and high-bind polystyrene tubes offer ideal optical quality, and low binding, polyethylene tubes feature chemical resistance when exposed to harmful substances. Tubes within the same size range also are available in thermally resistant polypropylene.
