Overview
The RS-20 Pro is a versatile rocker mixer that generates a smooth rocking motion to keep samples evenly mixed during processing. Unlike vigorous orbital systems, a wave motion shaker produces gentle agitation that helps minimise foaming and reduces stress on sensitive biological samples. As a result, this type of equipment is widely used in molecular biology, microbiology, immunology, cell culture, and general laboratory workflows. The controlled rocking action also supports staining, destaining, hybridisation, and blotting procedures where consistent sample movement is important. The compact benchtop design fits comfortably into research laboratories, universities, quality control facilities, and industrial testing environments throughout South Africa.

Applications

The gentle motion of a tilting shaker helps maintain sample suspension while reducing splashing. Therefore, laboratories can achieve effective mixing without introducing unnecessary mechanical stress. Many users also refer to this type of instrument as a see-saw shaker or laboratory wave shaker, depending on the application and industry terminology. These Rocking Shakers support a wide range of scientific and industrial applications. Common uses include:
  • Western blot washing
  • Membrane staining and destaining
  • Immunoassay procedures
  • Cell culture applications
  • DNA and RNA sample preparation
  • Hybridization protocols
  • Protein analysis workflows
  • Reagent mixing
  • Quality control testing

Performance and Convenience

The adjustable speed range allows users to tailor mixing intensity to specific protocols. Consequently, delicate biological samples can receive gentle agitation, while routine laboratory tasks can benefit from faster mixing speeds. The digital interface simplifies operation and improves reproducibility between runs. Moreover, the timer function enables unattended operation, which helps laboratory staff manage multiple tasks efficiently. Because the RS-20 Pro has a practical 250 × 250 mm platform, users can process multiple containers simultaneously. This feature improves workflow efficiency while maintaining a compact footprint. Furthermore, the instrument’s straightforward design reduces training requirements, making it suitable for both experienced researchers and new laboratory personnel.

Safety and Reliability

The brushless DC motor delivers stable operation while reducing wear associated with traditional brushed motors. Therefore, laboratories benefit from reduced maintenance requirements and dependable day-to-day performance. In addition, the balanced rocking mechanism helps maintain smooth movement across the speed range. The stable platform design also assists with container security during operation. Because the unit operates quietly, it fits comfortably into research, teaching, and industrial laboratory environments where excessive noise can become disruptive.
