Globe Scientific Wireless Tube Rack (20mm, 40-Place Full Size) handles the wider tube diameters used in clinical chemistry, environmental testing, and research. At 20mm, filled tubes are substantially heavier than 13mm tubes — making the structural integrity of the rack critical. Reinforced nylon provides rigidity under the combined weight of 40 full tubes without the flex, bending, or structural failure that coated-wire racks experience over time.
Heavy Tube Loads Need Structural Integrity
A 20mm tube filled with 15mL of liquid weighs approximately 20 grams. Forty of them add 800 grams to the rack — nearly two pounds of asymmetric load that shifts when tubes are inserted or removed. Wire racks under this load deform at their weakest points: the welded joints where wire meets wire. The wireless nylon rack has no joints — it is one continuous piece that distributes load across the entire structure. No weak points, no deformation, no premature failure.
