Benchmark Scientific R4045 Lab Rotator with Tube Holder Starter Set, 30x1.5ml, 8x15ml and 2x50ml

The Benchmark R4045 is ideal for laboratories requiring gentle, repeatable mixing for biological, molecular, and clinical workflows. It is commonly used for blood sample mixing, immunoprecipitation, protein binding studies, nucleic acid preparation, hybridization, cell suspensions, and sample resuspension where controlled rotational movement helps maintain sample consistency without harsh agitation.

The Benchmark R4045 includes interchangeable holders for 30 × 1.5/2.0 mL tubes, 8 × 15 mL tubes, and 2 × 50 mL conical tubes, allowing laboratories to process multiple sample sizes using one instrument. Additional optional holders and accessories are available for higher-capacity workflows or specialized applications such as hybridization and blot washing.

Yes. The R4045 features programmable speed control from approximately 1 to 80 rpm and offers multiple mixing modes, including continuous 360° rotation, pause intervals, reversing actions, and customizable mixing programs. This flexibility helps laboratories adapt the mixer to both gentle sample rolling and more vigorous rotational mixing needs.

Yes. The Benchmark R4045 includes a programmable timer ranging from 1 second to 99 hours and 59 minutes, plus continuous operation mode for extended procedures. Timed workflows help laboratories standardize protocols and reduce operator intervention during repetitive sample preparation or incubation steps.

Yes. The Benchmark R4045 is designed for use in cold rooms and incubators, with an operating temperature range of approximately +2°C to +70°C. This makes it a strong choice for temperature-sensitive applications where samples must be mixed while maintaining controlled environmental conditions.
