Hanuo TYZD-IIIA Digital Syphilis Rotator

Overview

The Hanuo TYZD-IIIA Digital Syphilis Rotator is a precision-engineered clinical rotator designed specifically for standardized mixing in serological diagnostic workflows. It operates on the principle of orbital rotation—generating consistent, low-shear motion via a fixed eccentric drive mechanism—to ensure uniform reagent dispersion without compromising antigen-antibody integrity or latex particle stability. Unlike general-purpose shakers, this instrument is optimized for low-volume, high-sensitivity immunoassays including rapid syphilis test card processing, latex agglutination assays, and complement fixation tests (CFT). Its stable rotational profile minimizes bubble formation and sedimentation artifacts, supporting reproducible endpoint interpretation in CLIA-waived and moderate-complexity clinical laboratories. The device complies with IEC 61010-1 safety standards for laboratory electrical equipment and is engineered for continuous operation under ambient laboratory conditions (15–30 °C, ≤80% RH non-condensing).

Key Features

• Digital dual-display interface showing real-time rotational speed (rpm) and remaining timer duration—enabling precise protocol adherence and audit-ready documentation.
• Adjustable speed control (10–210 rpm) with fine-tuned resolution, allowing method-specific optimization for diverse assay kinetics—from slow incubation-phase mixing to rapid endpoint agitation.
• Fixed 22 mm orbital diameter ensures repeatable shear stress across all operating speeds, critical for maintaining colloidal stability in latex-based reagents.
• Single-platform design (314 × 218 mm) accommodates standard 96-well microplates, strip racks, and lateral flow test cards; platform surface features non-slip rubber matting to prevent sample tube displacement.
• Robust mechanical architecture with sealed induction motor and thermal overload protection (2 A fuse), supporting unattended 24-hour operation in high-throughput clinical settings.
• Low power consumption (15 W) and silent operation (<45 dB(A)) minimize environmental impact and support integration into laminar flow cabinets or shared diagnostic workstations.

Sample Compatibility & Compliance

The TYZD-IIIA is validated for use with common syphilis serology formats including rapid plasma reagin (RPR), toluidine red unheated serum test (TRUST), and treponemal-specific IgM/IgG lateral flow assays. It maintains compatibility with polystyrene, polypropylene, and glass reaction vessels (0.5–5 mL volume range). While not a temperature-controlled device, its ambient-use configuration aligns with CLSI EP12-A2 guidelines for non-thermostatic mixing devices in qualitative immunoassay protocols. The unit meets CE marking requirements per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), and supports GLP-compliant recordkeeping when paired with external time-stamped loggers.

Software & Data Management

This is a standalone electromechanical rotator with no embedded firmware or network connectivity. All operational parameters are set manually via front-panel rotary encoder and push-button controls. Digital display outputs are analog-to-digital converted and shown directly—no data export, USB interface, or PC synchronization capability is provided. For regulated environments requiring electronic records, users may integrate the device into broader lab information systems (LIS) via external timing validation logs or video-monitored operation protocols compliant with FDA 21 CFR Part 11 Annex 11 principles (where local policy permits).

Applications

• Mixing of RPR/TRUST test cards during flocculation phase (typically 4–8 rpm for 4–8 min, per CDC-recommended protocols).
• Uniform dispersion of latex particles in treponemal antigen suspensions prior to assay loading.
• Agitation of serum-complement mixtures in classical complement fixation testing (CFT), minimizing false-negative results from incomplete complex formation.
• Standardized resuspension of dried reagents in point-of-care (POC) infectious disease panels, including HBV, HCV, and HIV rapid tests where rotational mixing is specified.
• Supporting ISO 15189-accredited quality control procedures for inter-laboratory assay reproducibility assessment.

FAQ

Is the TYZD-IIIA suitable for use with microcentrifuge tubes or PCR strips?
Yes—its flat, non-slip platform accommodates 0.5–2.0 mL tube racks and 8-strip PCR carriers when secured with compatible holders; however, it is not designed for high-speed vortexing or centrifugal force generation.
Does this device meet FDA or CE regulatory requirements for clinical diagnostics?
It carries CE marking under applicable EU directives for electrical safety and electromagnetic compatibility; however, it is classified as an ancillary laboratory accessory—not an IVD device—and does not require FDA 510(k) clearance.
Can the timer be disabled for continuous operation?
Yes—the “0” setting on the timer activates continuous run mode until manually powered off.
What maintenance is required for long-term reliability?
Routine cleaning of the platform surface with 70% ethanol and periodic inspection of the eccentric drive coupling for wear; no lubrication or calibration is required.
Is there a service manual or technical support available in English?
Hanuo provides bilingual (CN/EN) operation instructions and basic troubleshooting guides; extended technical support is available through authorized distributors in APAC and EMEA regions.
