Globe Scientific Polycarbonate Microcentrifuge Tube Rack — 24-Place, Stackable, -80°C to 121°C

Globe Scientific Polycarbonate Stackable Microcentrifuge Tube Rack (456335 series) is a 24-place rack for 1.5mL and 2.0mL tubes in polycarbonate — clearer, tougher, and more dimensionally stable than polypropylene. The clear variant lets you check fill levels without pulling tubes. All colors stack vertically for organized freezer storage and withstand the full range from autoclave (121°C) to ultra-low freezer (-80°C).

Why Polycarbonate Over PP

PP racks flex under a full tube load and become opaque over time. Polycarbonate stays rigid and transparent indefinitely. Impact resistance exceeds PS and acrylic — the rack survives benchtop drops that shatter other materials. For labs that cycle racks between the bench, autoclave, and -80°C freezer, PC handles the thermal extremes without warping, cracking, or dimensional change.
