Description
Nalgene™ Unwire™ half-size test tube racks organise and store samples in a compact layout ideal for incubators, refrigerators, freezers, laboratory fume hoods and bench tops. This blue-green Unwire™ test tube half-rack uses a 4 × 4 array and holds 16 tubes of 25 mm diameter, giving each vessel a dedicated position in a rectangular, space-saving form. The half-size design is intended for environments where full racks would waste chamber or bench area, while still keeping larger-diameter tubes stable and easy to retrieve. Constructed from acetal plastic and specified as autoclavable, the rack supports standard laboratory cleaning and sterilisation practice. Overall dimensions are 12,2 × 12,2 × 7,6 cm (approximately 4,8 × 4,8 × 3 in.), matched to 25 mm tubes. Half-size Unwire™ racks from manufacturer Thermo Scientific - Laboratory Plastics help maintain clear sample order during cold storage, incubation and open-bench handling. Supplied as a case of 8, the product suits multi-user laboratories or inventory stocking, combining defined tube spacing with a reduced footprint for efficient use of limited laboratory space.
