Rack, test tube, no-wire

Ninety-place No-Wire Rack features locking mechanism that prevents “floaters” in water baths and speeds decanting by allowing the whole rack to be inverted. Heavier-than-water polypropylene assures non-floating racks when immersed, even inagitated water. Autoclavable. Numbered and lettered rows (6 x 15 array) aid in identification of tubes (10-13 mm diameter). Collapsible for storage, yet assemble in seconds. Overall dimensions: 24.8 x 10.5 x 7 cm (9.75 x 4.12 x 2.75").
