Test Tube Racks and Holders | Thermo Fisher Scientific

Rely on Thermo Scientific plastic test tube racks to provide reliable support and organization for your lab's test tubes, centrifuge tubes, conicals, and other tubes in the 13–30mm diameter range.

It's time to clean out any mushy, moldy old wooden racks left from the 1980s and replace them with easy-to-clean, sturdy and durable, high-quality plastic racks. Are rusty metal racks with peeling colored coatings and broken welds the bane of your lab? Replace them with Nalgene Unwire racks. Don't settle for flimsy knock-offs that won't support the weight of a full load of tubes.

You can count on these test tube racks to get the job done right and get your lab refreshed and organized for the important jobs ahead.

Select a Nalgene unwire rack

Replace your metal test tube racks with our most popular plastic racks. Nalgene Unwire Racks have no coating to chip, peel, or rust. These racks are molded in a single piece for exceptional strength and durability. Nalgene Unwire racks securely support a full load of filled test tubes or centrifuge tubes. The smooth finish leaves fewer places for contaminants to hide; no welds to break, no sharp edges, and no assembly required—ready to use. Molded in a variety of bright, fade-resistant colors to help organize your lab and your samples. Endplates accept large labels for easy identification of samples.
