Polypropylene Grip Test Tube Racks

Decanting and water bath work is a snap when you use these racks. Four tiny retaining fingers in each well of the two plates of the rack grip the tubes firmly in any position, even upside down. Molded of autoclavable polypropylene, the racks have end plates for labeling, and numbered and lettered rows for laboratory identification. Racks can be stacked for storage. Size: 25 x 11 x 7cm.
