Scienceware® Floating Bubble Microcentrifuge Tube Racks

Made especially for use with beakers, these space-saving racks are ideal for small quantities of microcentrifuge tubes or cryogenic vials and are perfect for use in microbiology and immunology labs. They are molded of buoyant TPX® brand polymethylpentene with tiny bubbles throughout for additional buoyancy. Insert tubes from the top and easily remove them by pressing the rack down on the bench.
