Ratek RM4 Series Digital Rotary Mixer Descriptions

Application for Rotary Mixers

Perfect for diverse laboratory applications spanning biochemistry, molecular biology, clinical diagnostics, and histochemistry, while accommodating any research or analytical procedure requiring gentle yet thorough end-over-end mixing action.

  • End over end mixing action
  • Microprocessor controlled drive system
  • 3 user pre-set programs
  • Silent operation
  • Can be customised to suit your application

Ratek RM4 Medium Rotary Mixer Description:

The Ratek RM4 Medium Rotary Mixer represents the medium-capacity solution in this advanced mixing series, delivering thorough sample preparation through its signature end-over-end mixing action. This precision-engineered unit features a microprocessor-controlled drive system that ensures consistent performance, while the large digital display provides clear visibility of both set and actual speeds during operation. The RM4's versatility shines through its accommodation of various laboratory containers via adjustable 3-prong clamps that securely hold vessels ranging from 5-70mm diameter up to 250mm in length within their protective plastic-coated jaws. Enhanced user convenience comes from the comprehensive electronic timer system offering settings from 0-99 minutes or hours, complemented by three programmable memory buttons that store preferred speed and time combinations for repeated protocols.

Please Note - The RM4 & RM42P do not come with clamps or clip carrier.

 

Ratek RM42P Large Rotary Mixer Description:

The Ratek RM42P Large Rotary Mixer serves as the large-capacity variant, building upon the RM4's proven design with expanded mixing capabilities for higher-throughput applications. This robust mixer maintains the same precision ball bearing-mounted rotating bar and silent-belt drive system that characterizes the series, while incorporating the advanced brushless motor technology that ensures long-term reliability and whisper-quiet operation. The RM42P's sophisticated control interface features highly visible LED displays for both timing and tachometer functions, complete with an audible alarm system to alert operators when cycles are complete. Like its medium counterpart, the RM42P offers extensive customization options including interlocked safety covers and specialized clamping fixtures, making it adaptable to diverse laboratory requirements while maintaining the series' hallmark precision digital speed control and programmable operation capabilities.

Please Note - The RM4 & RM42P do not come with clamps or clip carrier.

 

Ratek RM4C Medium Mixer with Universal Carrier Description:

The RM4C Medium Mixer with Universal Carrier stands out as the ideal solution for laboratories requiring efficient mixing of multiple samples simultaneously, specifically engineered to accommodate entire loaded tube racks and specialized vessels without time-consuming sample transfer. This innovative mixer features sliding foam-covered clamp plates that adjust seamlessly to secure tubes and containers up to 200mm in height within its generous working area of 220mm width, 260mm depth, and 200mm height. The unit's universal clamping system eliminates the need for individual tube handling, allowing researchers to load complete racks and initiate mixing protocols immediately, making it exceptionally valuable in high-throughput environments where efficiency and sample integrity are paramount.

Built around the same reliable end-over-end mixing principle that defines the RM4 series, the RM4C incorporates sophisticated timing and programming capabilities through its large, user-friendly control panel that manages the comprehensive electronic timer system spanning 0-99 minutes or hours. The three programmable memory buttons enable storage of frequently used speed and time combinations, streamlining routine procedures while maintaining consistent results across different applications. This versatility, combined with the proven Ratek engineering excellence that has established the brand as Australia's leading laboratory mixer manufacturer, makes the RM4C an indispensable tool for laboratories requiring flexible, reliable mixing solutions across multiple research disciplines.
