Description
Nalgene™ Unwire™ test tube rack with Resmer™ manufacturing technology is a rectangular acetal rack built to hold complete series of larger test tubes or centrifuge tubes safely. Configured as a 3 × 8 Unwire array, it provides 24 positions with 30 mm openings for 30 mm tubes. Dimensions are 28,3 × 10,8 × 9,2 cm (length × width × height), balancing capacity with a manageable bench footprint. The white rack is autoclavable, enabling standard laboratory sterilisation between workflows, and the open structure keeps tube contents and labels easy to see during sample handling, incubation or interim storage. Within the Nalgene Unwire range from Thermo Scientific, this model addresses organisation of 30 mm reagent and centrifuge tubes in research, quality-control and routine analytical laboratories. Acetal construction supports repeated daily use while maintaining upright, ordered placement of full tube series across common laboratory procedures.
