Clay Adams 421105 Nutator Rotating Platform Mixer

Clay Adams 421105 Nutator Rotating Platform Mixer. This benchtop instrument provides a continuous, three-dimensional nutating (combined rocking and rotating) motion to facilitate the gentle but thorough mixing of fluid samples. Its specialized figure-eight mechanical drive prevents sample foaming and cellular shear stress, making it an essential asset for maintaining the homogeneity of sensitive biological and hematological suspensions.

• MPN / Catalog Model: 421105
• Manufacturer & Line: Clay Adams (historically a specialized laboratory equipment brand of BD Diagnostics)
• Quantity & Packaging / Form Factor: Single compact benchtop unit (approximately 10" W x 5" D x 6" H) weighing roughly 2 lbs, featuring an open-access platform design.
• Material Construction / Metallurgy: Outfitted with an elastomeric rubber dimpled mat engineered to securely grip and retain smooth cylindrical tubes via friction, eliminating the need for mechanical clamps or racks.
• Technical Specifications & Tolerances: Operates on 115-117V AC, 50/60Hz (0.03A) with a steady, fixed rotational speed between 12 and 24 RPM depending on the regional electrical frequency. The platform can securely hold up to 15 standard analytical tubes of 7 mL, 10 mL, or 15 mL volumetric capacities simultaneously.
• Hardware & System Compatibility: Universally compatible with BD Vacutainers, clinical blood collection tubes, microcentrifuge tubes, and standard glass or polymer laboratory vials. The open design allows operators to dynamically add or remove hardware during operation without pausing the motor.
• Standards, Cleanliness & Purity: Electrical components carry CSA (Canadian Standards Association) safety certification.
• Primary Application: Pre-analytical hematology workflows, continuous agitation of whole blood samples, biological pellet resuspension, and rapid tissue fixation processes where continuous, non-foaming mixing is critically required.
