The 4-Way Flipper benchtop storage system combines four racks in one. Designed to support a variety of tube sizes and styles, each rack can be rotated to any of the four sides to support different size centrifuge tubes. Their rugged polypropylene construction allows them to be autoclaved, placed in a freezer or used in waterbaths. Regardless of the support position used, the 2 x 7 in. or the 3 1/2 x 8 in. format is small enough to be used under the hood or on the benchtop. Rack will hold four 50 mL conical tubes, twelve 15 mL conical tubes, thirty-two 1.5/2.0 mL microcentrifuge tubes and thirty-two 0.5 mL microtubes.
