Product Description
LIGHT LABS is proud to offer the Benchmark Scientific Rotating Mixer (Cat # R5010) — a uniquely versatile tube rotating mixer that combines two independent adjustments not found together in any other Benchmark Scientific rotator: variable speed from 1 to 40 RPM AND variable tilt angle from 0° (true horizontal/rolling) to 90° (true vertical/end-over-end) — providing complete control over both the speed and the geometry of rotation simultaneously for the widest range of mixing applications in a single instrument. The ability to set any tilt angle between 0° and 90° makes the R5010 uniquely adaptable — researchers can dial in the exact rotation geometry required by their specific protocol, from pure rolling action for hybridization and cell culture incubations to true end-over-end inversion for maximum bead resuspension and blood mixing.
The R5010 is further distinguished by its reversing mode — a unique feature for vigorous mixing applications where standard continuous rotation is insufficient. In reversing mode, the mixer rotates up to 360° in one direction, then stops and rotates in the reverse direction — repeating this back-and-forth action continuously until the timer expires. This alternating reverse rotation creates significantly more turbulent mixing within each tube vs. continuous one-directional rotation — ideal for resuspending difficult pellets, mixing high-viscosity samples, and any application where maximum mixing intensity is required.
Three rubber-coated rotisserie tube holders are included — covering 1.5/2.0 mL, 15 mL, and 50 mL tubes simultaneously with a maximum capacity of 48 x 1.5/2.0 mL, 20 x 15 mL, or 12 x 50 mL. The rubber coating on each rotisserie provides a secure, non-slip grip that prevents tubes from wobbling or loosening during high-speed operation — a critical safety and performance feature at maximum mixing intensities. Programmable timer: 1 second to 99 hours 59 minutes. Cold room and incubator compatible (+4°C to +65°C). Universal voltage. 2-year warranty. LIGHT LABS is your trusted source for Benchmark Scientific laboratory equipment.
KEY FEATURES
- Dual independent adjustability — variable speed (1–40 RPM) AND variable tilt angle (0°–90°); unique combination not found in any other Benchmark Scientific rotator; complete control over both speed and rotation geometry
