HUXI HTG-6D Orbital-Rolling Shaker

Overview

The HUXI HTG-6D Orbital-Rolling Shaker is an engineered solution for gentle, uniform mixing of viscous, particulate-laden, and shear-sensitive samples in clinical, diagnostic, and research laboratories. Unlike conventional vortex mixers that rely on high-speed orbital agitation, the HTG-6D employs a dual-mode mechanical oscillation system—combining controlled orbital rolling with programmable bidirectional rolling—to generate laminar, low-shear motion across multiple tubes simultaneously. This principle ensures effective homogenization without cavitation, foaming, or cellular disruption—critical for whole blood handling, immunoassay preparation, sediment resuspension, and suspension-based cell culture workflows. Designed for compliance with routine laboratory quality systems, the unit operates within defined environmental tolerances (5–40 °C, ≤80% RH) and meets IP21 ingress protection standards for dust resistance and limited vertical drip protection.

Key Features

• Microprocessor-controlled DC brushless motor delivering stable speed output from 20 to 100 rpm with ±2 rpm repeatability under full load;
• Dual oscillation modes: standard unidirectional orbital rolling and programmable alternating-direction rolling for enhanced sample dispersion;
• Large-format 6-roller configuration (280 mm roller length) accommodating tubes ranging from 10 mL to 50 mL conical centrifuge tubes, glass vials, and PCR strips;
• LCD interface displaying real-time speed (rpm), elapsed time, and remaining timer duration; intuitive rotary encoder for parameter input;
• Extended timer range from 1 minute to 99 hours and 59 minutes, supporting both timed and continuous operation protocols;
• Low-power consumption (15 W) and silent operation (<45 dB(A)) suitable for shared lab environments and overnight incubation-compatible workflows;
• Rugged powder-coated steel housing with reinforced roller axle supports ensuring mechanical stability during prolonged use at maximum amplitude (24 mm).

Sample Compatibility & Compliance

The HTG-6D is validated for use with whole blood, serum, plasma, bacterial suspensions, polymer solutions, and heterogeneous solid–liquid dispersions where preservation of structural integrity is essential. Its gentle rolling action prevents hemolysis and maintains platelet morphology—enabling anticoagulant-free blood sample processing per CLSI H20-A2 guidelines. The device conforms to IEC 61010-1:2010 safety requirements for electrical equipment used in laboratory settings. While not certified for GMP or ISO 13485 manufacturing environments, its design supports traceable operation when integrated into GLP-aligned SOPs—including manual log entries for run parameters, duration, and operator ID. No internal data storage or electronic audit trail is provided; all operational records must be maintained externally.

Software & Data Management

The HTG-6D operates as a standalone hardware platform with no embedded firmware update capability or PC connectivity options (e.g., USB, RS-232, or Bluetooth). All configuration—including speed selection, timer setup, and mode activation—is performed locally via the front-panel LCD and rotary encoder. No proprietary software, drivers, or cloud services are required or supported. Users are advised to document operational parameters manually or integrate the shaker into existing LIMS or ELN platforms using external timestamped logs. For regulated environments requiring electronic record integrity, the unit may be operated under 21 CFR Part 11-compliant procedures only when paired with validated third-party data capture tools and procedural controls.

Applications

• Anticoagulant-free blood sample homogenization prior to hematocrit measurement or peripheral blood smear preparation;
• Resuspension of pelleted cells, precipitated proteins, or microbial colonies without mechanical shearing;
• Uniform mixing of high-viscosity reagents such as agarose gels, hydrogels, and magnetic bead suspensions;
• Stabilization of immunoassay plates during incubation steps to minimize edge effects and improve inter-well reproducibility;
• Pre-analytical processing in clinical chemistry and transfusion medicine labs adhering to CAP or COLA accreditation standards;
• Long-duration mixing of slow-reacting enzymatic assays or ligand-binding reactions requiring uninterrupted agitation over several hours.

FAQ

Does the HTG-6D support external triggering or remote start/stop commands?
No. The unit has no digital I/O ports or communication interfaces. All operations must be initiated and monitored locally.
Can the roller angle or tilt be adjusted?
No. The six rollers are fixed at a standardized horizontal orientation optimized for tube stability and fluid dynamics consistency.
Is calibration documentation available from the manufacturer?
HUXI provides factory-set speed verification reports upon request, but does not supply NIST-traceable calibration certificates or user-accessible calibration routines.
What maintenance is required for long-term reliability?
The brushless motor requires no lubrication or scheduled servicing. Routine cleaning of the roller surface and housing with 70% ethanol is recommended between uses.
Are replacement rollers or custom tube holders available?
Standard replacement rollers (Part No. HTG-ROL-280) and universal silicone tube clamps are offered by HUXI as optional accessories.
