Ratek RPM5 and ERPM4 Medium Rocking Mixer Descriptions

Applications for Rocking Mixers

The variable speed control system enables effortless adjustment between gentle and vigorous agitation levels, providing optimal versatility for a comprehensive range of laboratory tasks. This precise speed control is particularly valuable for applications such as blot washing procedures, gel staining and de-staining protocols, and various hybridization techniques where different agitation intensities are required for optimal results.

Ratek RPM5 Digital Rocking Mixer Description:

The Ratek RPM5 Digital Rocking Mixer delivers exceptional versatility for various mixing and washing applications through its precise variable speed control and adjustable tilt action capabilities. The digital speed control system operates across a range of 4-57 RPM, managed through an intuitive front panel interface featuring a large LED display that shows both set and actual speeds for accurate monitoring. Advanced slow acceleration technology is integrated into the drive system to minimize spillage risk during startup, while the comprehensive timer function can be programmed from 0-99 in either minutes or hours to accommodate diverse protocol requirements. Three memory buttons provide convenient storage of frequently used time and speed combinations, enabling consistent reproducibility across repeated experiments.

Engineered for reliability and extended operation, the RPM5 features super-quiet solid-state mixer control with optical feedback, allowing for unattended operation during lengthy procedures without laboratory disruption. The mechanically adjustable tilt angle ranges from +/-7° to +/-15° from horizontal (factory preset at 10°), providing optimal agitation characteristics for different sample types and container configurations. With a maximum capacity of 6kg, the unit accommodates substantial workloads while maintaining stable performance. The included nitrile mat provides secure container positioning for low-speed applications, while optional racks such as the RR5 Universal rack offer enhanced versatility with adjustable rubber-covered bars that can secure various container types including test tube racks, trays, and flasks for higher-speed operations.

  • Max. capacity of 6kg
  • Super-quiet operation
  • Solid-state mixer control with optical feedback
  • Tilt angle mechanically adjustable +/-7° to +/-15° from horizontal (factory preset at 10°)

This general-purpose benchtop rocking platform operates across a speed range of 5-50 RPM with solid-state speed control, incorporating slow acceleration technology to minimize spillage risks during startup sequences. The super-quiet operation enables extended unattended use without disrupting the laboratory environment, while the robust construction supports a maximum capacity of 5kg for substantial sample loads.

Designed for versatility and ease of use, the ERPM4 features a mechanically adjustable tilt angle ranging from +/-7° to +/-15° from horizontal (factory preset at 10°) to optimize mixing characteristics for different applications. The included nitrile mat provides adequate container security for low-speed operations, while optional accessories expand the unit's capabilities significantly. The RR5 Universal rack offers adjustable rubber-covered horizontal bars that accommodate various container types including test tube racks, trays, and flasks, while dedicated stainless steel Tulip clips are available for securing conical flasks ranging from 50ml to 2 liters. This combination of affordability, reliability, and accessory compatibility makes the ERPM4 an ideal choice for laboratories requiring dependable rocking mixer performance without complex controls.
