Brightly colored high density polyethylene foam racks are ideal for floating tubes in water baths, tubs or beakers. Closed cell foam is resistant to water absorbtion so racks can be washed and reused. Foam handles make it easy to lift samples out of baths.

Three sizes are available to accommodate the most commonly used tubes. Choose yellow microtube rack for up to 24 x 1.5-2.0 mL microtubes, blue 15 mL tube rack for tubes for conical tubes and culture tubes and green 50 mL tube rack for large conical bottom tubes. The forth rack is blue multipurpose microtube rack that features unique "x" slits which can hold 0.2 mL, 0.5 mL 1.5 mL and 2.0 mL microtubes. Racks are sold as packs of 5.
