Globe Scientific Snap-N-Rack 25mm Tube Rack - 40-Place, PP, 4 Colors

Globe Scientific's Snap-N-Rack ships flat to minimize pre-use storage footprint, then snaps into a rigid, fully functional tube rack with no tools in seconds. The 25mm Snap-N-Rack holds 40 25mm OD tubes with all positions angled uniformly — the defining feature of the Snap-N-Rack design that ensures every tube in the rack receives identical heat exposure during water bath and incubator protocols, eliminating the temperature gradient edge effects that compromise reaction consistency in conventional upright-tube racks.

Available in four colors at $42.10/EA — 456703 (White) · 456704 (Blue) · 456706 (Yellow) · 456710 (Red) — the color selection enables batch coding without cost penalty. Polypropylene construction provides chemical resistance to standard lab reagents and autoclavability for decontamination between specimen batches. The flat-pack format reduces shipping volume and allows bulk rack inventory to be stored compactly before assembly, making the Snap-N-Rack a practical choice for labs that maintain on-hand rack inventory for variable-volume processing periods.

Features and Benefits

• Flat-Pack, Snap-Together Design: Ships and stores flat to minimize footprint; assembles into a rigid rack without tools in seconds — enabling labs to stock bulk rack inventory compactly and assemble units at bench as needed during high-volume processing periods.

• Uniform Tube Angle Across All 40 Positions: All tube positions are oriented at the same angle, ensuring every tube in the rack experiences identical incubation conditions — critical for water bath and incubator timed reactions where temperature uniformity across the full rack is required for reproducible results.

• Fits 25mm Tubes: Compatible with standard 25mm OD test tubes, culture tubes, and centrifuge tubes across Globe Scientific and other major lab tube manufacturers.

• 4 Colors, Same Price: All four colors are identically priced — enabling color-coded batch organization by assay type, priority, processing day, or technician assignment without any cost differential for color choice.

• Polypropylene — Chemical-Resistant and Autoclavable: PP resists standard lab reagents, buffers, and disinfectants, and the rack can be autoclaved for decontamination between specimen batches — supporting sterile technique and routine equipment decontamination protocols.

• High-Density Capacity in a Single Rack Footprint: The high tube-count format maximizes bench and incubator utilization — reducing the number of individual rack moves required during batch processing compared to equivalent-capacity arrangements using smaller conventional racks.

Specifications

Laboratory Applications

• Bench organization and incubation of 25mm OD tubes across clinical chemistry, cell culture, microbiology, and sample preparation workflows, where uniform tube-angle positioning across all rack positions ensures consistent incubation conditions and reproducible reaction outcomes

• Water bath and incubator timed-reaction protocols where temperature uniformity across the full tube rack is critical — the uniform angle design eliminates the outer-row cooling differential that causes variable endpoint results in upright-tube conventional racks

• High-throughput labs maintaining bulk rack inventory — flat-pack format allows large rack purchases to be stored in minimal shelf space and assembled at bench as needed during surge processing periods without requiring pre-assembled rack storage space

• Color-coded multi-batch processing workflows where different assay types, patient groups, or processing priorities need to be visually segregated across concurrent bench runs using differently colored racks without any cost overhead for color selection

Frequently Asked Questions

What tubes does this rack fit?
Standard 25mm OD tubes. Slightly oversized tubes may sit loosely; undersized tubes will not seat correctly. Verify your tube OD against 25mm before ordering.

Does the Snap-N-Rack hold tubes upright or at an angle?
The Snap-N-Rack positions all tubes at a uniform angle — not fully upright. This is the intentional design feature that enables consistent incubation: every tube is oriented identically so all receive equal heat exposure in a water bath or incubator. If strict upright tube orientation is required for your workflow, a conventional upright tube stand is more appropriate.

Is the Snap-N-Rack available in other tube sizes?
Yes. The Snap-N-Rack line covers: 12/13mm 90-place, 16/17mm 60-place, 20/21mm 40-place, 25mm 40-place, 30mm 24-place, and 1.5/2.0mL microcentrifuge 100-place. See individual product pages for each size. All sizes available in four colors at the same price point.

Can the assembled rack be autoclaved?
Yes. Disassemble the snap-together rack before autoclaving for thorough surface decontamination, then re-snap for reuse. Replace the rack if the snap fit has loosened after repeated autoclave cycles.
