Hanuo TYZD-IIIA Digital Syphilis Rotator

Overview

The Hanuo TYZD-IIIA Digital Syphilis Rotator is a precision-engineered rotary shaker specifically optimized for serological assay protocols requiring consistent, low-shear orbital motion. It operates on the principle of eccentric circular oscillation—driving a single flat platform through a fixed 22 mm stroke diameter at adjustable rotational speeds between 0 and 210 rpm. Unlike general-purpose incubator shakers or vortex mixers, this instrument is purpose-built for antigen-antibody agglutination assays, particularly Rapid Plasma Reagin (RPR) testing, latex agglutination, and complement fixation reactions. Its mechanical architecture prioritizes stability and reproducibility over wide speed ranges, minimizing sample splashing and ensuring uniform reagent mixing across multiple test cards placed simultaneously on the 314 × 218 mm platform. The device complies with basic electrical safety standards (IEC 61010-1) and is intended for use in clinical laboratories operating under Good Laboratory Practice (GLP) frameworks.

Key Features

• Digital LED display showing real-time rotational speed (rpm) and countdown timer—enabling precise protocol adherence without manual monitoring.
• Stepless speed control from 0 to 210 rpm via rotary encoder, allowing fine-tuned optimization for different assay kinetics (e.g., slower agitation for delicate complement binding vs. faster mixing for RPR card activation).
• Programmable timer with 0–24 hour countdown range; “0” setting enables uninterrupted operation for extended incubation-mixing cycles.
• Rigid aluminum alloy platform with non-slip rubber mat surface, engineered to secure standard RPR test cards (75 × 50 mm), latex slide assays, and microtiter strips without displacement.
• Low-power brushless motor (≤15 W) ensures thermal stability during prolonged operation and eliminates carbon brush wear—critical for maintenance-free deployment in high-throughput diagnostic labs.
• Compact footprint (approx. 350 × 260 × 140 mm) and silent operation (<45 dB(A)) support integration into laminar flow hoods, biosafety cabinets, or crowded benchtop environments.

Sample Compatibility & Compliance

The TYZD-IIIA accommodates up to 12 standard RPR test cards or eight 12-well latex agglutination slides per run, depending on layout configuration. Its 22 mm orbital stroke provides optimal shear profile for particle aggregation without disrupting immunocomplex integrity—a key requirement for qualitative serological interpretation. While not certified to ISO 13485 or FDA 21 CFR Part 11, the unit supports traceable assay execution when paired with lab-defined SOPs and manual log entries. It is routinely deployed in Chinese CDC-affiliated institutions, blood banks, dermatology & STD clinics, and hospital clinical laboratories where regulatory expectations align with WS/T 417–2013 (Clinical Laboratory Equipment Management Guidelines) and GB/T 27025–2019 (General Requirements for Competence of Testing and Calibration Laboratories).

Software & Data Management

This is a standalone electromechanical instrument with no embedded firmware, network interface, or data export capability. All operational parameters are set manually and retained only during active power supply. For auditability, users are advised to record speed, duration, and lot numbers in paper-based or LIMS-integrated electronic logs. The absence of digital storage or remote access ensures compliance with data sovereignty requirements in regulated environments where uncontrolled data transmission is prohibited.

Applications

• Rapid Plasma Reagin (RPR) and Venereal Disease Research Laboratory (VDRL) slide tests for syphilis screening.
• Latex agglutination assays for rheumatoid factor, CRP, ASO, and other autoantibody panels.
• Complement fixation tests requiring gentle, sustained agitation to promote immune complex formation.
• Antigen-coated bead mixing in point-of-care immunoassay development workflows.
• Controlled reagent homogenization prior to ELISA plate loading or lateral flow strip application.

FAQ

Is the TYZD-IIIA compatible with ISO/IEC 17025-accredited testing?
Yes—when operated within documented SOPs, with periodic speed verification using an external tachometer, and integrated into a laboratory’s internal calibration and maintenance schedule.
Can it be used for non-serological applications like cell suspension or enzyme assays?
Not recommended. Its fixed 22 mm stroke and lack of temperature control limit utility outside low-viscosity, room-temperature immunoassays.
Does the device include speed calibration certification?
No factory calibration certificate is supplied; users should verify rpm accuracy annually using a handheld optical tachometer traceable to national standards.
What maintenance is required?
Routine cleaning of the platform surface and inspection of fuse integrity; no lubrication or alignment adjustments are necessary due to sealed motor and bearing design.
Is there a CE or UL mark?
The unit meets basic EMC and safety requirements per GB 4793.1 but does not carry CE, UL, or UKCA marks—intended for domestic and export markets requiring self-declared conformity only.
