Product Details
The Thermo Scientific™ Nalgene™ Unwire™ test tube racks are designed to securely hold a full load of test tubes or centrifuge tubes with diameters of 13mm, 16mm, 20mm, 25mm, and 30mm. These racks are molded in a single piece, ensuring exceptional strength and durability without any coatings that may chip, peel, or rust. They feature a smooth finish that minimizes places for contaminants to lodge, eliminating welds that can break and sharp edges. The endplates of the racks can accommodate large labels for easy sample identification. With a higher specific gravity than water, these racks remain submerged in a water bath without floating, and they can withstand most lab chemicals and temperatures up to 121°C for various laboratory procedures. The racks come in six bright colors for better organization of samples. They are specifically designed so that 15ml conical tubes fit in the 20mm racks, while 50ml conical tubes are compatible with the 30mm racks. No assembly is required as the rack is ready to use. Note that these items will not ship to residential addresses.
