Overview
The Hanuo TYMR-II Roller Mixer is a compact, benchtop mechanical mixing device engineered for consistent, low-shear rotational homogenization of liquid and semi-solid samples in clinical, diagnostic, and life science laboratories. Operating on the principle of continuous axial rolling—where tubes or vials are secured on a horizontally oriented rotating plate—the instrument induces gentle yet effective circumferential motion that promotes uniform suspension without foaming, phase separation, or cell lysis. Unlike orbital shakers or vortex mixers, roller mixers minimize shear stress and air entrapment, making them particularly suitable for sensitive biological matrices such as anticoagulated whole blood, coagulation controls, lyophilized reagents, and immunoassay calibrators. The TYMR-II is designed for routine, high-throughput sample preparation where reproducibility, operator independence, and hands-free operation are critical to assay integrity.
Key Features
- Digital LED display with real-time speed readout and intuitive push-button interface for precise speed selection across 0–80 rpm range
- Stepless electronic speed control ensures stable rotational output at any setpoint, eliminating mechanical gear slippage or torque drop-off
- Single-plate architecture with optimized roller geometry accommodates standard 12–17 mm diameter tubes (e.g., EDTA, citrate, or heparin vacutainers), microcentrifuge tubes, and small-volume glass vials
- Low-power 12 W brushless motor delivers quiet, maintenance-free operation with thermal protection and extended service life
- Compact footprint (394 × 266 × 98 mm) enables integration into biosafety cabinets, cold rooms, or crowded benchtop environments without compromising accessibility
- Robust ABS+PC housing with non-slip rubber feet ensures stability during prolonged operation and meets IEC 61010-1 electrical safety requirements for Class I laboratory equipment
Sample Compatibility & Compliance
The TYMR-II supports a wide range of primary and secondary containers used in hematology, clinical chemistry, and quality control workflows—including plastic and glass tubes up to 15 mL volume, snap-cap vials, and pre-filled reagent cartridges. Its 22 mm ±1 mm effective rolling amplitude (as verified per internal calibration protocol) provides sufficient lateral displacement to suspend particulates while preserving erythrocyte morphology and antigen integrity in whole blood specimens. The device complies with CE marking requirements under Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), and conforms to IEC 61010-1:2010 for safety in laboratory electrical equipment. While not certified for GMP or FDA 21 CFR Part 11 environments out-of-the-box, its design facilitates integration into GLP-compliant workflows when paired with documented SOPs and periodic performance verification (e.g., speed accuracy check using external tachometer).
Software & Data Management
The TYMR-II operates as a standalone analog-digital hybrid instrument with no embedded firmware, network interface, or data logging capability. All operational parameters—including speed setting and elapsed time—are manually configured and monitored via the front-panel digital display. This architecture eliminates software validation overhead and ensures deterministic behavior required in regulated settings where audit trails are managed externally. Users may record operational logs manually or integrate the unit into LIMS-controlled workflows via external timers or programmable relays. No proprietary drivers, cloud connectivity, or firmware updates are required or supported.
Applications
- Homogenization of anticoagulated whole blood prior to hematocrit, CBC, or coagulation testing (PT, APTT, fibrinogen)
- Reconstitution and mixing of lyophilized controls, calibrators, and enzyme-linked reagents in ELISA and CLIA platforms
- Uniform dispersion of insoluble standards in lipid panel assays or particle-based immunoassays
- Pre-analytical conditioning of CSF, synovial fluid, or pleural effusions to prevent cellular sedimentation
- QC batch mixing for proficiency testing programs requiring inter-laboratory consistency
- Supporting ISO 15189-accredited medical laboratories in fulfilling requirement 5.3.2 (equipment suitability and verification)
FAQ
Does the TYMR-II support timed operation?
No—the TYMR-II does not include a built-in timer function. Operation duration must be managed externally using a stopwatch or integrated laboratory timer system.
Can it accommodate 50 mL conical tubes?
No—its roller plate geometry is optimized for tubes ≤17 mm in diameter and ≤15 mL volume. Larger vessels exceed mechanical clearance and compromise rotational stability.
Is speed calibration traceable to national standards?
The unit ships with a factory calibration certificate verifying speed accuracy within ±3% of setpoint at 25 °C ambient; users may perform in-house verification using a NIST-traceable optical tachometer.
What maintenance is required?
No scheduled maintenance is needed. Wipe exterior surfaces with 70% ethanol; avoid solvents on display or housing. Motor and bearings are sealed and non-serviceable.
Is the TYMR-II suitable for use inside a refrigerated incubator?
It is rated for ambient operation between 5–40 °C and relative humidity ≤80% non-condensing. Extended use below 15 °C may affect display response and motor startup torque; consult application engineer before cold-room installation.
