Benchmark Scientific R2020 Roto-Mini Rotator with tube holders, 115V

The Benchmark R2020 is ideal for laboratories that require gentle, repeatable tube mixing for biological, clinical, and molecular workflows. It is commonly used for sample resuspension, protein binding studies, nucleic acid purification, histochemistry, hybridization procedures, blood sample mixing, and reagent blending where consistent rotational movement helps maintain sample uniformity without aggressive agitation.

The R2020 includes interchangeable tube holders that support a wide range of laboratory sample sizes, from 0.5 mL microtubes to 50 mL conical tubes. Included holders typically accommodate 1.5/2.0 mL microcentrifuge tubes, 5–7 mL tubes, 10–15 mL tubes, and 50 mL tubes, allowing laboratories to work with multiple sample formats using a single instrument.

The Benchmark R2020 operates at a fixed speed of approximately 24 rpm, making it a simple, plug-and-run solution for laboratories that want repeatable mixing without manual speed adjustments. The consistent rotation rate helps standardize workflows and reduce variability between runs for routine applications.

Yes. The R2020 allows users to adjust the rotisserie orientation between vertical end-over-end rotation and horizontal rolling or hybridization-style mixing. This flexibility allows the same mixer to support both gentle rolling motions for delicate samples and more thorough rotational mixing when needed.

Yes. The Benchmark R2020 features a compact benchtop footprint and durable construction designed for routine laboratory workflows. Its interchangeable tube holders, lightweight design, and dependable fixed-speed motor make it practical for crowded workstations, research labs, clinical settings, and educational environments performing repetitive mixing tasks.
