Test Tube Stand 3 Tier PP
Product Code : EL-TT-10161
Quick answer: A 3-tier polypropylene test tube stand holds three rows of test tubes on one lightweight, chemical-resistant frame, so a single stand can rack far more tubes than a flat single-row holder. Lab Glassware Manufacturer's Test Tube Stand 3 Tier PP is available in 14 diameter/hole-count combinations, from 13mm tube holes up to 32mm, and from 12 up to 72 holes per stand.

Choosing a Tube Diameter and Hole Count
Match the diameter row to the outside diameter of the tubes actually in use — a stand sized for 13mm tubes will not safely hold 25mm tubes, and vice versa. Hole count should be picked against batch size: a 62- or 72-hole stand suits a busy teaching lab running full-class practicals, while a 12- or 18-hole stand is enough for a research bench running smaller batches. Polypropylene construction keeps the stand light enough to carry fully loaded and resists most common lab reagents better than untreated wood.
Frequently Asked Questions
What tube diameters does the Test Tube Stand 3 Tier PP fit?
It is available in five diameters — 13mm, 15mm, 16mm, 20mm, 25mm and 32mm — across 14 diameter/hole-count combinations in total.
How many tubes can one stand hold?
Hole count ranges from 12 holes up to 72 holes per stand depending on the diameter and size variant chosen.
Why choose a polypropylene stand over a wooden or wire one?
Polypropylene is lightweight and resists most common laboratory reagents better than untreated wood, and will not rust the way an uncoated wire stand can.
