Snap-N-Rack Tube Rack for 20mm and 21mm Tubes, 40-Place, PP, Blue

The Snap N Rack Tube Rack is a reliable and space-saving solution designed for efficient organization of laboratory test tubes. Built to hold 40 tubes with diameters of 20mm and 21mm, this rack is made from durable polypropylene (PP), offering excellent chemical resistance and long-term performance in demanding laboratory environments.

To help laboratories maximize storage efficiency, the rack is shipped flat and easily snaps together for quick assembly. Once assembled, it provides a strong and stable structure for securely holding test tubes during experiments, storage, and transport. The thoughtful design also allows uniform temperature exposure, making it suitable for sample incubation and other temperature sensitive procedures.

These test tube racks are designed to perform reliably in freezer environments, maintaining their structure without becoming brittle or deforming at low temperatures. It is also autoclavable, allowing for effective sterilization and repeated use in sterile laboratory settings.

For better organization and quick sample identification, alphanumeric markings are molded directly into the rack. These markings help users easily track and locate specific test tubes during laboratory workflows. The rack is non-floating in water baths, ensuring stability during experiments, and it can be stacked when empty to save space in storage areas.

The blue color also supports color-coded sample organization systems, helping laboratories improve workflow efficiency and reduce sample handling errors.
