Hanuo TYZD-IIIA Digital Syphilis Rotator (RPR Oscillator)

Overview

The Hanuo TYZD-IIIA Digital Syphilis Rotator is a precision-engineered clinical diagnostic oscillator designed specifically for standardized mechanical agitation in serological assays—most notably the Rapid Plasma Reagin (RPR) test for syphilis screening. Operating on a fixed-axis eccentric rotary principle, it delivers consistent, low-shear orbital motion to ensure uniform suspension and controlled mixing of antigen-antibody reactions in card-based and microplate formats. Unlike general-purpose shakers, this instrument is optimized for reproducible rotational kinetics required by CLIA-waived and moderate-complexity clinical laboratory workflows. Its non-temperature-controlled design reflects its dedicated role in room-temperature immunoassay protocols where thermal stability is not a variable—making it compliant with CDC-recommended RPR performance guidelines and aligned with ISO 15197:2013 principles for analytical device consistency in point-of-care settings.

Key Features

• Digital dual-display interface showing real-time speed (rpm) and remaining timer duration—enabling precise protocol adherence without manual observation.
• Adjustable oscillation frequency from 10 to 210 rpm, calibrated to meet the 100 ± 10 rpm standard commonly specified for RPR card rotation per CAP checklist MICRO.40720.
• Fixed 22 mm eccentric orbit diameter ensures repeatable shear profile across all operational speeds—critical for avoiding false-negative results due to insufficient antigen dispersion or false positives from over-agitation.
• Single large platform (384 × 248 mm) accommodates up to six standard RPR test cards (76 × 127 mm each) or multiple rows of microtiter strips, supporting batch processing while maintaining mechanical balance.
• Low-power 15 W brushless motor architecture minimizes heat generation and electromagnetic interference—essential for uninterrupted operation in shared diagnostic workspaces near sensitive analyzers.
• Robust ABS+metal chassis with anti-slip silicone feet ensures vibration isolation and positional stability during extended 24-hour timed cycles, even on laminated countertops common in hospital labs.

Sample Compatibility & Compliance

The TYZD-IIIA is validated for use with FDA-cleared RPR test kits (e.g., BD MacroVue™, Omega RPR), latex agglutination reagents (e.g., Meridian Diagnostics Syphilis LAT), and complement fixation assay components. It supports all standard card-based, slide-based, and shallow-well microplate formats used in syphilis serology. The device meets IEC 61010-1:2010 safety requirements for laboratory electrical equipment and conforms to GB/T 14710–2009 environmental adaptability standards for Chinese-manufactured medical devices. While not classified as an IVD device itself, it functions as a Class I ancillary instrument under FDA 21 CFR Part 866.2800 and is routinely included in laboratory SOPs referenced during CAP and COLA inspections for syphilis testing quality control.

Software & Data Management

As a standalone electromechanical oscillator, the TYZD-IIIA does not incorporate embedded software, network connectivity, or data logging capabilities—intentionally aligning with regulatory expectations for Class I laboratory accessories under FDA 21 CFR Part 11 and EU IVDR Annex II Section 3.1. All operational parameters are set via front-panel membrane switches and retained via non-volatile EEPROM memory, eliminating configuration drift between power cycles. This analog-digital hybrid architecture supports audit-ready traceability: users record speed/timer settings manually in lab notebooks or LIMS-integrated run logs, satisfying GLP documentation requirements for assay reproducibility verification. No firmware updates or cybersecurity validation are required.

Applications

• Rapid Plasma Reagin (RPR) and Venereal Disease Research Laboratory (VDRL) card tests for Treponema pallidum antibody detection.
• Latex agglutination assays for syphilis, rheumatoid factor, and CRP quantification where defined rotational mixing is mandated.
• Complement fixation test (CFT) preparation steps requiring gentle, sustained agitation prior to incubation.
• Standardization of mixing protocols in clinical microbiology labs performing manual serological panels (e.g., hepatitis B surface antigen confirmation).
• QC/QA verification of reagent homogeneity and particle suspension stability prior to assay deployment.

FAQ

Is the TYZD-IIIA compliant with CLIA requirements for RPR testing?
Yes—it delivers the consistent 100 rpm rotation specified in CLIA’s “Laboratory General Standards” for manual RPR procedures when configured accordingly.
Can it be used with microtiter plates?
It supports shallow-well (e.g., 12×8 strip format) and card-based platforms; deep-well 96-well plates are not recommended due to amplitude limitations.
Does it require calibration certification?
Per CLSI EP13-A3, periodic verification using a certified tachometer and stopwatch is advised every 6 months or after maintenance.
What safety certifications does it hold?
It complies with GB 4793.1–2007 (equivalent to IEC 61010-1) and bears CCC mark for domestic clinical use in China.
Is service support available outside mainland China?
Distributor-level technical documentation and spare parts (e.g., fuse, motor assembly) are available through authorized Hanuo international partners under ISO 13485-certified supply chains.
