Product Details
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, providing exceptional strength and durability without any coatings that could chip, peel, or rust. The smooth finish minimizes areas for contaminants to accumulate, while the absence of welds prevents breakage and eliminates sharp edges. The endplates are designed to accept large labels for easy sample identification. With a higher specific gravity than water, these racks remain submerged in a water bath and do not float. They are resistant to most laboratory chemicals and can withstand temperatures up to 121°C, making them suitable for a variety of lab procedures. Available in six vibrant colors for better sample organization, the racks accommodate 15ml conical tubes in the 20mm racks and 50ml conical tubes in the 30mm racks. No assembly is required as the rack comes ready to use. Note: will not ship to residential addresses.
