Nalgene™ Unwire™ half-size test tube racks with Resmer™ manufacturing technology provide space-saving organisation for sample tubes in incubators, refrigerators, freezers, fume hoods and on the bench. This white rectangular half-rack is intended for 20 mm tubes and offers a 4 × 5 array with 20 sample positions, balancing capacity with a compact outline. Manufactured from acetal plastic, it is autoclavable for reliable re-use in standard laboratory sterilisation routines. Overall dimensions are 12,7 × 10,5 × 8,4 cm (length × width × height), so the rack fits constrained shelves and work surfaces while still securing a full set of tubes. The Unwire™ construction holds vessels firmly without a conventional wire frame, supporting preparation, short-term storage and transfer steps. Half-size format is especially useful when full-length racks are impractical, yet clear positioning of each tube remains essential. Supplied as a case of 8 from manufacturer Thermo Scientific - Laboratory Plastics, these racks help laboratories keep 20 mm test tubes orderly across research, quality-control and everyday analytical tasks.
This article is part of Test tube racks, in Stands, clamps & racks.

Questions about Nalgene™ Unwire™ Half-Racks: Resmer™ Manufacturing
What is this article?
Nalgene™ Unwire™ Half-Racks: Resmer™ Manufacturing is the article on this page. Luminix Health distributes Thermo Scientific - Laboratory Plastics for laboratory use. It sits in Reageerbuisrekken, inside Statieven, klemmen & rekken, in Labmateriaal.
A test-tube rack holds tubes upright in an order the operator can read back. The hole diameter and the number of places have to match the tubes. An autoclave-safe rack and a cardboard rack are not interchangeable once heat is involved.
A stand, a clamp and a rack hold something still so the hands can do the work. A bosshead locks a clamp to a rod. A test-tube rack keeps tubes upright and in an order the operator can read back. The failure is almost always mechanical: the clamp slips, or the rack does not match the tube diameter. The glass they support is indexed under ISO laboratory glassware.
