Globe Scientific Reversible Microcentrifuge Tube Rack (456350 series) provides two tube capacities in a single rack. One side holds 80 tubes in the 1.5mL and 2.0mL size range — the standard microcentrifuge tubes used across molecular biology, clinical laboratories, and general research. Flip the rack over and it holds 60 tubes in the 0.2mL and 0.5mL range — PCR tubes and small-volume sample tubes. One rack replaces two, cutting both cost and benchtop clutter in half.
Why Reversible Design Saves More Than Space
Traditional labs stock separate racks for 1.5mL tubes and 0.2mL PCR tubes — twice the inventory, twice the storage, and the wrong rack is always the one in the drawer. The reversible design eliminates that problem. During a typical molecular biology workflow — DNA extraction in 1.5mL tubes, then PCR setup in 0.2mL tubes — you work from one side of the rack, flip it, and continue with the next tube size. No switching racks, no searching for the right one. In shared labs where multiple users bring different tube sizes to the same bench, one reversible rack handles everything anyone brings.
Autoclavable Polypropylene for Bench and Freezer
The polypropylene construction withstands standard autoclave cycles (121°C, 15 psig, 20 minutes) and provides excellent chemical resistance to the solvents, acids, and cleaning agents used in laboratory environments. Critically, PP remains flexible and impact-resistant at freezer temperatures — unlike polystyrene and acrylic, which become brittle and crack at -20°C and -80°C. For labs that move racks between the bench and the freezer, polypropylene is the correct material choice because it survives the thermal cycling without degradation.
7 Colors Plus Assorted
Available in blue, natural, green, orange, pink, red, and yellow as individual colors, plus an assorted pack containing one of each color. Color-coded racks provide instant visual identification of sample sets, experiments, time points, or user assignments in shared laboratory spaces. The assorted pack is a cost-effective way to set up a complete color-coding system in one purchase.
80/60-Place vs. 96/96-Place with Cover
Globe Scientific offers two reversible rack models. This 80/60-place model (456350 series) is the compact, coverless option designed for active benchtop work where you need quick tube access and minimal footprint. The 96/96-place model with cover (456355 series) holds more tubes on each side and includes a snap-on lid for transport protection and freezer storage. Choose the 80/60-place for daily benchtop workflows. Choose the 96/96-place with cover for freezer storage and sample transport applications.
