A tube stand that tips over mid-run doesn't just waste reagent — it creates a biohazard cleanup and restarts a protocol. Globe Scientific's Reinforced Polypropylene Tube Stands are built for labs that need reliable, autoclavable tube organization across multiple tube diameters and color-coded workflows. The three-tier design holds tubes securely upright across the full tube body height, and reinforced PP construction provides the structural rigidity to stay planted on a busy bench even when fully loaded. Sturdy integrated handles allow the entire loaded stand to be moved between bench, incubator, and autoclave without disturbing the tubes.
Available in five tube diameter sizes — 13mm (31-place), 16mm (31-place), 20mm (20-place), 25mm (18-place), and 32mm (12-place) — and four colors (Blue, Red, White, Yellow) at the same price. The 4-color availability in every size enables color-coded lab organization by assay type, priority, technician, or day-of-week without any cost premium for the color choice. All variants are fully autoclavable at 121°C, making them appropriate for sterile technique applications and hot-cycle decontamination between specimen batches.
Features and Benefits
Reinforced PP for Stability Under Load: Manufactured from reinforced polypropylene with greater rigidity than standard PP — the stand maintains its flat, non-tipping form factor even when all tube positions are filled with capped tubes, on wet bench surfaces, and during incubated rotation or shaking protocols.
Three-Tier Tube Support: Three horizontal tiers grip the tube body at spaced intervals along its length, preventing tubes from leaning, cross-touching, or falling — critical for timed reaction protocols where lateral tube contact can cause uneven temperature distribution or cross-contamination between adjacent samples.
5 Tube Sizes, 4 Colors, All Same Price: 13mm (31-place), 16mm (31-place), 20mm (20-place), 25mm (18-place), 32mm (12-place) — all available in Blue, Red, White, and Yellow at $20.50/EA. Size and color can be mixed freely to match every bench tube format and color-coding system without budget penalty.
Fully Autoclavable at 121°C: All size and color variants are rated for standard autoclave cycles at 121°C, making these stands appropriate for sterile technique labs, decontamination protocols between specimen batches, and any workflow requiring hot-cycle processing of equipment between uses.
Integrated Handles for Loaded Transport: Molded handles at each end of the stand allow a fully loaded rack to be picked up and moved safely — no hand-under-rack balancing, no risk of tipping during transfers between bench stations, incubators, or water baths.
Color Coding for Lab Organization: The 4-color system allows labs to assign colors by assay, priority tier, patient group, processing day, or technician — reducing handling errors in high-throughput batch processing where multiple specimen sets are processed simultaneously on adjacent bench stands.

Laboratory Applications
Bench organization for clinical chemistry, urinalysis, and serology tube processing, holding 13mm, 16mm, or 20mm test tubes and centrifuge tubes upright through specimen receipt, processing, and result reporting stages
Color-coded batch processing in high-throughput labs where multiple assay batches are processed concurrently — using differently colored stands to visually segregate specimen groups by test panel, priority level, or processing status across a shared bench workspace
Sterile technique and autoclave-cycle applications in microbiology and tissue culture labs where racks must be hot-cycle decontaminated between uses — the reinforced PP construction withstands repeated 121°C autoclave cycles without warping or color change
Research and teaching labs requiring low-cost, durable, multi-size tube organization that accommodates mixed tube inventories across 13–32mm diameter formats without requiring separate rack purchases for each tube size in the lab's inventory
Frequently Asked Questions
Which tube size should I order?
Match the tube diameter to your most common tube OD: 13mm for standard clinical chemistry and urine vacuum tubes; 16mm for most test tubes and some centrifuge tubes; 20mm for larger centrifuge tubes and culture tubes; 25mm for universal tubes and certain specimen containers; 32mm for larger culture vessels. When in doubt, slightly oversized is better than undersized — tubes should sit with some clearance, not be forced through the holes.
Are all colors the same price and in stock?
Yes — Blue (B), Red (R), White (W), and Yellow (Y) are all priced identically at $20.50/EA per stand. Color availability may vary; check current stock status in the variant selector above.
What autoclave conditions are the stands rated for?
All Globe Scientific reinforced PP tube stands in this series are rated for standard gravity and prevacuum autoclave cycles at 121°C. Repeated autoclaving may cause minor color fading over time, which does not affect structural performance. Do not autoclave at temperatures above 121°C.
Can the stands be used in a water bath or incubator?
Yes. The reinforced PP construction is stable across standard lab temperature ranges from refrigerator temperatures (4°C) through incubator temperatures (up to ~70°C for standard incubation). For water bath use, confirm the stand dimensions allow full immersion to the required tube depth without the rack floating; the handles provide a convenient grip point for lifting a loaded stand from the bath.
