Benchmark Scientific R4040 Lab Rotator with Tube Holder Starter Set, 12x1.5ml, 2x15ml and 2x50ml

The Benchmark R4040 is ideal for laboratories that require controlled rotational mixing for biological, molecular, and clinical workflows. It is commonly used for blood sample mixing, immunoprecipitation, protein binding studies, hybridization, cell suspensions, nucleic acid preparation, and reagent mixing where gentle but consistent agitation helps maintain sample uniformity. Its programmable motion makes it useful for both delicate and repetitive protocols.

The Benchmark R4040 includes interchangeable holders for 12 × 1.5/2.0 mL tubes, 2 × 15 mL tubes, and 2 × 50 mL tubes, making it easy to begin mixing multiple sample formats immediately after setup. Additional optional holders can be added to increase capacity or support specialty applications such as horizontal mixing for blotting or hybridization workflows.

Yes. The R4040 features digital variable speed control from 1 to 80 rpm and supports multiple operating modes including continuous rotation, pauses, reversing actions, and programmable mixing sequences. Custom program modes allow laboratories to create repeatable protocols tailored to different sample sensitivities and workflow needs.

Yes. The Benchmark R4040 includes a programmable timer ranging from 1 second to 99 hours and 59 minutes, plus continuous operation mode for extended mixing procedures. This helps standardize protocols, reduce manual monitoring, and improve repeatability during repetitive laboratory processes.

Yes. The R4040 is designed to operate in cold rooms and incubators, with an operating temperature range of approximately +2°C to +70°C. This makes it useful for temperature-sensitive biological and molecular applications where samples require mixing under controlled environmental conditions.
