Interpretive Summary: Laboratory sample storage solutions are expensive and inflexible. This 3D printed device securely holds 50 mL tubes and can easily be stacked in refrigerated storage or on bench tops. Additionally, the rack is free-standing and can be used for organizing samples in other formats such as ice buckets. This tool simplifies laboratory sample management and allows equipment to be retrofitted for new purposes. Expensive racks can be substituted with this one.

Technical Abstract: This 3x5 laboratory rack allows for easy stacking on bench shelves, refrigerators, and freezers. The sides are equivalent to those of our 15 mL stackable rack allowing for easy swapping between the two models. The rack is designed so that most standard 50 mL tubes (with caps installed) sit comfortably beneath the sides. The depth of most -80 freezers can accommodate three of these racks in a line. The modular nature of this model also allows it to be used for other purposes. Remove the top and bottom shelf to create a sonicator bath tube holder or place the shelves in ice buckets to keep samples upright.
