Globe Scientific Snap-Together Microcentrifuge Tube Rack — 128-Place, Ships Flat, Reinforced PP, Autoclavable

Globe Scientific Snap-Together Microcentrifuge Tube Rack (456315 series) ships completely flat and assembles in seconds — push the sides together until they click, and you have a rigid 128-place rack for 1.5mL and 2.0mL microcentrifuge tubes. No tools, no hardware, no instructions needed. The flat-shipping design reduces packaging volume by over 80% compared to pre-assembled racks, which translates to real savings on freight costs and storage shelf space when ordering in quantity.

128-Place in a Ship-Flat Package

A stack of 10 unassembled 456315 racks occupies barely more shelf height than a single assembled rack. For teaching institutions ordering 30+ racks at semester start, biorepositories stocking hundreds of racks, or facilities outfitting new laboratory benches, the storage savings between delivery and deployment day are substantial. Once assembled, the snap joints are permanent — no risk of the rack coming apart during use, even under the stress of fully loaded tube weight.

Reinforced Polypropylene: Rigid Under Load

Standard PP racks flex when loaded with 128 tubes — the center of the rack bows, tube positions shift, and the rack rocks on the benchtop. The 456315 uses reinforced polypropylene (RPP) that maintains flatness and rigidity across the full 128-position span. This matters because a flexed rack surface tilts tubes off-vertical, making them harder to grip and increasing the chance of a tube popping out when an adjacent tube is pulled. RPP also withstands autoclave sterilization, freezer temperatures without becoming brittle, and sinks in water baths for temperature equilibration.
