Laboratory Blood Tube Rocking and Rolling Rotary Shaker Mixer

The RM-6H and RM-8H are horizontal-axis roller mixers designed for gentle homogenization of laboratory liquid samples. Unlike swing-type roller mixers, these units adopt stable horizontal rolling motion to realize uniform mixing with low turbulence. They are widely used to process blood samples, biochemical reagents, cell suspensions and other fragile biological samples that cannot withstand vigorous shaking. Two configurations are available: the 6-roller RM-6H and the 8-roller RM-8H to match different sample volumes.

Advantages

Digital Precise Control

It uses physical buttons paired with a digital display panel. Operators can intuitively adjust rotation speed and set mixing time, with clear screen readouts to guarantee consistent, repeatable experimental parameters across batches.

Adjustable Rotation & Long Timing

• Rotation speed is continuously adjustable between 20 rpm and 80 rpm, covering mild slow blending and regular-speed mixing needs.
• Timing function supports 1 minute to 23 hours and 59 minutes, flexible for short quick mixing and long-time overnight rolling incubation.

Anti-lock Protection Design

The built-in anti-jam mechanical structure avoids motor stalling triggered by uneven sample weight or accidental blockage. It protects internal driving components and enables long-term reliable continuous operation.

Sample Compatibility & Loading Capacity

• All rollers measure 280 mm long, fitting tubes with outer diameters ranging from 6 mm to 34 mm, compatible with standard test tubes and 50 mL centrifuge tubes.
• RM-6H maximum load: holds 10 pieces of 50 mL centrifuge tubes (total weight 0.5 kg).
• RM-8H maximum load: accommodates 14 pieces of 50 mL centrifuge tubes (total weight 0.7 kg).

Electrical & Mechanical Specifications

• Power consumption: 25 W.
• Wide universal input voltage: AC 100–240 V, suitable for laboratory power grids worldwide.
• Overall dimensions
  • RM-6H: 440 mm × 255 mm × 105 mm
  • RM-8H: 430 mm × 320 mm × 100 mm

Compact footprint saves valuable bench space in clinical labs, research institutes and testing laboratories.

Applications

Ideal for clinical blood testing, serological experiments, pharmaceutical preparation, biological sample blending, environmental liquid mixing and general lab sample pre-processing. Smooth horizontal rolling prevents liquid splashing, cell rupture and protein denaturation, preserving sample integrity.
