Manufacturer Description

The VWR Rotating Mixer XL is a versatile laboratory instrument engineered to provide both gentle and vigorous sample agitation. Designed for high-utility environments, this mixer features a digitally controlled interface for precise speed and timing, ensuring reproducible results across protocols. Unlike standard single-direction rotators, the Rotating Mixer XL offers a "Reverse Mode," which cycles the rotisserie 360° before automatically switching direction, providing superior homogenization for viscous samples. 

Technical Specifications

  • Capacity: 48 x 1.5/2.0 mL
  • Speed Range: 1 to 40 RPM (Digitally adjustable)
  • Mixing Angle: 0° to 90° (Adjustable to full horizontal)
  • Timer: 1 second to 9 hours, plus continuous operation mode
  • Mixing Modes: Standard Rotation & Reverse / Oscillating Mode
  • Footprint: 21 x 26.7 x 31.8 cm (8.25" x 10.5" x 12.5")
  • Electrical: 115V, 60Hz
  • Value-Add: Features rubber-coated steel tube clips that provide a secure, non-slip grip, preventing tube ejection even during vigorous reverse-cycling operations.

System Compatibility

The system accommodates the most common industry-standard centrifuge tubes:

  • Microcentrifuge Tubes: 1.5 mL and 2.0 mL
  • Conical Tubes: 15 mL and 50 mL (not included)
  • Note: The clips can be tensioned to hold similar-sized proprietary vials or glass test tubes.

Applications

Ideal for general lab workflows requiring controlled sample agitation:

  • Hematology: Keeping whole blood samples in suspension to prevent settling.
  • Molecular Biology: Mixing DNA/RNA extraction buffers and keeping beads in suspension during immunoprecipitation.
  • Chemistry: Preparation of homogeneous dispersions and dissolutions.
  • Clinical Diagnostics: Repeatable mixing for enzyme assays and titration protocols.
