The Benchmark Scientific RotoMini™ Tube Rotator (R2020) is a compact, fixed-speed laboratory rotator engineered for gentle, end-over-end tube mixing in research, clinical, and molecular biology workflows. Designed to accommodate a wide range of tube formats—from microcentrifuge tubes to 15 mL and 50 mL conicals—the RotoMini™ delivers smooth, uniform mixing that supports resuspension, protein binding, nucleic acid purification, hybridization, staining, and other applications requiring continuous low-shear rotation.

Operating at a steady 24 RPM, the R2020 provides consistent, reproducible mixing without the need for speed adjustments, making it ideal for routine protocols where predictable agitation is critical. Its interchangeable tube holders allow quick configuration changes, enabling users to mix different tube sizes simultaneously or switch between applications without additional tools. The compact footprint fits easily on crowded benchtops, while the quiet, maintenance-light design ensures reliable performance during long mixing cycles.

For labs that require more advanced mixing modes—such as variable speed, oscillation, or pulse operation—the RotoMini™ Plus variant is available. However, for foundational sample mixing tasks that demand simplicity, reliability, and continuous end-over-end motion, the R2020 remains one of the most versatile and dependable tube rotators available.
