Globe Scientific 15mL / 50mL Centrifuge Tube Rack - 50-Place, ABS, Orange | 456930

Labs using both 15mL and 50mL centrifuge tubes typically need separate racks for each format — or they improvise with mismatched holders that barely contain the larger 50mL conical tubes upright. Globe Scientific's 15mL/50mL Centrifuge Tube Rack eliminates the need for two separate rack types: a single ABS rack holds twenty 50mL conical tubes and thirty 15mL centrifuge tubes simultaneously, covering both formats in one compact bench footprint. The flat-pack, easy-assembly design means the rack ships compact and assembles at bench in seconds, reducing storage volume before use.

Available as a single unit (456930, $38.70/EA, orange ABS) or as a 5-pack (456930-5, $97.90/PACK/5) for labs that need to maintain a standing stock or equip multiple workstations. The ABS material provides excellent chemical resistance and structural rigidity to keep both 15mL and 50mL tubes securely upright, including fully loaded 50mL conicals.

Features and Benefits

• Dual-Format: 20 × 50mL + 30 × 15mL: Holds both centrifuge tube sizes in one rack — 20 positions for 50mL conical tubes and 30 positions for 15mL centrifuge tubes — covering the two most commonly used centrifuge tube formats simultaneously without requiring two separate racks at the bench.

• Flat-Pack, Easy Assembly: Ships flat for compact pre-use storage; assembles in seconds at bench without tools. Labs can stock cases flat and assemble racks as needed rather than storing pre-assembled racks that consume significant shelf space.

• ABS Construction: Acrylonitrile butadiene styrene (ABS) provides excellent rigidity and chemical resistance for a rack designed to support the weight of fully loaded 50mL centrifuge tubes — larger tubes with more mass require a stiffer rack material than standard PP to prevent tube lean and rack flex.

• Single-Unit or 5-Pack: Order 456930 (EA) for individual workstations or rack replacement; order 456930-5 (PACK/5) for better per-unit economics when equipping multiple workstations or maintaining rack inventory.

Specifications

Laboratory Applications

• Research and clinical labs using both 15mL and 50mL centrifuge tubes in the same workflow — cell culture prep, buffer preparation, protein purification, and sample aliquoting protocols that require both tube sizes at the same bench station

• Space-constrained benches where consolidating 15mL and 50mL tube storage into a single rack footprint is preferable to maintaining two separate rack types side by side

• Tissue culture and fermentation labs that regularly handle both 15mL and 50mL conical tubes for cell counting, culture scaling, and media preparation in the same workflow session

Frequently Asked Questions

Does this rack work with branded centrifuge tubes from other manufacturers?
Yes — the 456930 holds standard 15mL and 50mL centrifuge tube formats from any manufacturer that follows the standard conical tube dimensions (15mL: approx. 17mm OD; 50mL: approx. 29mm OD). Globe Scientific's own 15mL and 50mL centrifuge tube lines are fully compatible.

Single unit (456930) vs 5-pack (456930-5)?
At $38.70/EA for the single and $97.90 for the 5-pack ($19.58/EA), the 5-pack offers meaningful per-unit savings for labs equipping multiple workstations or maintaining inventory. Order 456930 for one-off replacement; order 456930-5 for stocking.
