Description
Nalgene™ Unwire™ half-size test tube rack organizes and stores 13 mm tubes in a dense yet compact footprint. This rectangular half rack offers a 6 × 6 array with thirty-six sample positions, ideal for incubators, refrigerators, freezers, fume hoods and crowded benchtops where full-size racks take too much space. Manufactured from acetal plastic using Resmer™ technology, the green rack is autoclavable and designed for reliable tube support during routine sample handling and temporary storage. Opening diameter is 13 mm; dimensions are 10,2 × 10,2 × 5,6 cm (L × W × H). The half-size Unwire™ format from manufacturer Thermo Scientific - Laboratory Plastics keeps tubes upright and clearly arranged while remaining easy to move between cold storage, hoods and work areas. Its compact geometry suits multi-user labs that need high position counts without sacrificing shelf or incubator capacity. Supplied as a case of eight racks for consistent organization across stations, instruments and storage compartments.
