Benchmark Scientific R3005 5 Roller Mixer, Fixed 38 RPM, Roll & tilt, 13 mm Amplitude

The Benchmark R3005 is ideal for laboratories that require gentle, uniform mixing of liquid samples without excessive agitation or foaming. It is commonly used for blood sample mixing, cell culture preparation, bacterial suspensions, reagent blending, hybridization workflows, and resuspension of biological or chemical samples where consistent end-to-end mixing helps maintain sample integrity. Its roll-and-tilt motion is especially useful for suspensions and viscous liquids.

The Benchmark R3005 is designed to handle a wide variety of laboratory vessels, including Vacutainers™, centrifuge tubes, test tubes, culture bottles, and roller bottles ranging from approximately 8 mm to 200 mm in diameter. Its 5-roller platform supports both small tubes and larger sample containers, making it flexible for different laboratory workflows.

Unlike standard stationary roller mixers, the R3005 combines continuous rolling with a gentle 13 mm (0.5 inch) tilt amplitude, creating a wave-like mixing effect during each rotation. As the rollers move, samples are gently elevated and returned to a horizontal position, helping provide more complete end-to-end mixing and improved sample uniformity.

No. The Benchmark R3005 operates at a fixed speed of 38 rpm, selected to provide dependable mixing performance across a broad range of laboratory applications. This fixed-speed operation simplifies use and helps laboratories maintain repeatable, standardized mixing conditions without requiring speed adjustments.

Yes. The Benchmark R3005 is designed to operate in temperature-controlled environments, including incubators and cold rooms, with a recommended operating range of approximately 4°C to 40°C. This makes it suitable for temperature-sensitive biological, clinical, and molecular workflows that require continuous sample mixing under controlled conditions.
