Globe Scientific Snap-N-Rack 12/13mm Tube Rack - 90-Place, PP, 4 Colors

Shipping a rack flat and snapping it together at the bench sounds simple — and with Globe Scientific's Snap-N-Rack it actually is. The 12/13mm Snap-N-Rack arrives in a compact flat-pack format that reduces storage footprint before use, then snaps into a rigid 90-place tube rack in seconds with no tools and no assembly confusion. The special design positions all 90 tubes at the same angle for uniform incubation conditions — every tube in the rack experiences identical heat exposure when placed in a water bath or incubator, eliminating the temperature gradient edge effects that occur in conventional racks where outer-row tubes cool faster than inner-row tubes.

Available in four colors — White (456403), Blue (456404), Yellow (456406), Red (456410) — all at $31.40/EA, the Snap-N-Rack 12/13mm holds 12mm and 13mm OD tubes, covering standard clinical chemistry vacuum tubes, urinalysis tubes, and most small-diameter test tubes. The polypropylene construction is chemically resistant to common lab reagents and autoclavable for decontamination between specimen batches. At 90 positions per rack, a single Snap-N-Rack provides the tube capacity of multiple conventional small racks in a single organized footprint.

Features and Benefits

• Flat-Pack Shipping, Snap-Together Assembly: Arrives compact and flat for efficient storage before use; snaps into a rigid 90-position rack configuration without tools. Ideal for labs that receive periodic large orders and need efficient pre-use storage without dedicating shelf space to pre-assembled racks.

• Uniform Tube Angle for Consistent Incubation: All 90 tube positions hold tubes at the same angle, ensuring equal exposure to temperature during water bath and incubator protocols — eliminating the outer-row temperature differential that causes variable reaction times in standard upright-tube conventional racks.

• 90-Place High-Density Capacity: 90 tube positions per rack maximizes bench and incubator space utilization — a single Snap-N-Rack holds the equivalent of three 30-place conventional racks in the same footprint, reducing the number of rack moves during batch processing.

• Fits 12mm and 13mm OD Tubes: Compatible with 12mm and 13mm OD tubes — covering standard clinical chemistry vacuum tubes (most BD Vacutainer and similar formats), urine vacuum tubes (Globe Scientific 3861), and standard small-diameter test tubes used across clinical and research applications.

• 4 Colors, Same Price: White (456403), Blue (456404), Yellow (456406), and Red (456410) are all $31.40/EA, enabling color-coded batch organization by assay type, priority, or day without cost penalty for color selection.

• Polypropylene Construction, Autoclavable: PP is chemically resistant to common lab reagents, buffers, and disinfectants, and the rack is autoclavable for decontamination between specimen batches — appropriate for sterile technique workflows and routine equipment decontamination cycles.

Specifications

Laboratory Applications

• High-throughput clinical chemistry batch processing where 12mm and 13mm vacuum tubes need organized, high-density bench and incubator storage with color-coded batch differentiation across concurrent assay runs

• Water bath and incubator timed-reaction protocols requiring uniform tube-angle positioning across all 90 positions to ensure consistent exposure and eliminate the edge effects that cause variable reaction outcomes in standard upright-tube racks

• Labs with storage space constraints that need to maintain rack inventory without pre-assembling all units — flat-pack format allows bulk rack purchases to be stored compactly and assembled at bench as needed during high-volume processing periods

• Urinalysis and serology sections processing Globe Scientific 3861 vacuum tubes or other 12/13mm tube formats, where a single 90-place rack covers a complete batch run without requiring multiple smaller conventional racks per technician workstation

Frequently Asked Questions

Does the Snap-N-Rack hold tubes upright or at an angle?
The Snap-N-Rack design positions tubes at a uniform angle across all 90 positions — not fully upright. This angled positioning is the core feature that enables uniform incubation: all tubes in the rack are oriented identically, so every tube experiences the same water bath depth or air circulation exposure. If strict upright tube orientation is required (e.g., for sedimentation-sensitive specimens), a conventional upright tube stand may be more appropriate.

Is the Snap-N-Rack available in other tube sizes?
Yes. Globe Scientific offers the Snap-N-Rack in multiple tube diameter configurations. The 16/17mm version holds 60 tubes (SKUs 456503/504/506/510), the 20/21mm version holds 40 tubes (SKUs 456603/604/606/610), the 25mm version holds 40 tubes (SKUs 456703/704/706/710), and the 30mm version holds 24 tubes (SKUs 456803/804/806/810). All sizes are available in the same four colors at the same price point. Also available in a 90-place version for 1.5/2.0mL microcentrifuge tubes (456303/304/306/310).

How difficult is the snap-together assembly?
Assembly is straightforward — the rack components are designed to snap together without tools in under a minute. The assembly mechanism is rigid once snapped, providing a stable rack that does not flex or disassemble during normal use. No fasteners, adhesives, or tools are required.

Can the Snap-N-Rack be autoclaved?
Yes — the polypropylene construction allows autoclave decontamination. Disassemble the rack before autoclaving for thorough decontamination of all surfaces, then re-snap for reuse. Check for any warping after autoclaving; if the snap fit has loosened, replace the rack to maintain tube security.
