Organize 72 tubes in a full-size OneRack, choosing the well diameter that suits your 5–10 mL tube workflow.

Both rack formats are listed for 5–10 mL tubes and both hold 72 positions, but their well diameters and footprints differ. Choose 13 mm wells for the 7.9 × 4 × 2.3-inch rack or 16 mm wells for the 9.8 × 5 × 2.7-inch rack. Compare your tube body, cap clearance and intended handling method rather than assuming all 5–10 mL tubes share one outside diameter.
Molded coordinates provide fixed references for the sample map, while the flat labeling area identifies the rack itself. Teardrop-shaped openings help retain tubes, and the stable design is intended for water-bath use. Select white, blue, green and magenta to fit your laboratory’s color convention. Color is an organizational choice, not a change in the listed 72-well capacity.

This family is made from polypropylene with a published temperature range of 0 to 110°C. Do not substitute the higher temperature claim of a POM rack for this polypropylene family. Confirm chemical suitability and any required process conditions before use. Each ordering row supplies eight racks of the named configuration; a multicolor photograph is not an assorted-pack promise.
Compare the configuration and order unit in the ordering table. The listed pack belongs to one selected catalog number; a family photograph is not an assorted kit unless that row explicitly says assorted.
Compare an adjustable universal rack when one fixed well diameter does not cover your tube mix.
Compare a floating rack when flotation, rather than a stable standing water-bath rack, is required.
