Test Tube Stand Wire Pattern
Product Code : EL-TT-10156
Quick answer: This is a wire-construction test tube stand available in five size formats, each matched to a specific tube diameter and hole count — from 13mm tubes with 90 positions down to 30mm tubes with 21 positions — letting a bench hold either a large number of slim tubes or a smaller number of wider ones in the same style of stand.
| Tube Diameter | Number of Tube Positions |
|---|---|
| 13 mm | 90 tubes |
| 16 mm | 60 tubes |
| 20 mm | 40 tubes |
| 25 mm | 24 tubes |
| 30 mm | 21 tubes |
Why Wire Construction and Why Position Count Falls as Tube Size Rises
A wire-frame stand is lightweight, easy to see through to check tube contents at a glance, and simple to clean compared with a solid moulded stand, which is why it remains a common choice for general test tube storage in teaching and routine laboratory settings. The trade-off between tube diameter and position count follows directly from a fixed stand footprint: slimmer 13mm tubes pack in at up to 90 positions, while the widest 30mm tubes fit only 21 in a stand of a similar size, since each wider tube simply takes up more space in the frame. Choosing the right size means matching the stand to the actual tube diameter in use, both for a secure fit and to get the full benefit of the stand's position count.
Frequently Asked Questions
What sizes does this wire pattern stand come in?
It comes in five sizes matched to tube diameter and hole count: 13mm (90 tubes), 16mm (60 tubes), 20mm (40 tubes), 25mm (24 tubes) and 30mm (21 tubes).
Why does a larger tube diameter mean fewer stand positions?
Each stand has a broadly similar overall footprint, so a wider tube simply takes up more space per position, which reduces how many tubes fit compared with a stand sized for slimmer tubes.
Why choose a wire stand over a solid moulded one?
Wire construction is lightweight, lets users see tube contents from the side without lifting them out, and is straightforward to clean, which is why it remains a common choice for general and teaching laboratory use.
