Overview
The HTR-03 Vortex Mixer is a precision-engineered laboratory vortex shaker designed for reproducible, low-shear mixing of liquid samples in tubes, vials, and centrifuge containers. It operates on the principle of orbital oscillation—driving a horizontal circular motion at the base platform to induce controlled vortex formation in sample vessels placed on its adaptable roller assembly. Unlike high-speed centrifugal or magnetic stirrers, this device delivers gentle yet effective homogenization ideal for applications where sample integrity, bubble minimization, and consistent suspension are critical—such as immunoassay preparation, nucleic acid extraction, reagent resuspension, and solvent-based extractions in environmental and food safety workflows.
Key Features
- Adjustable rotational speed from 0 to 60 rpm with fine incremental control, enabling optimization across viscosity ranges—from aqueous buffers to moderately viscous organic extracts.
- Digital timer with 1-minute resolution and programmable range of 0–99 minutes, supporting unattended operation while maintaining traceability for GLP-compliant protocols.
- Modular roller drum configuration with variable inter-roller spacing, accommodating tube diameters from 10 mm to 18 mm—including standard 15 mL and 50 mL conical centrifuge tubes.
- Low-noise, brushless DC motor (30 W nominal power) ensures thermal stability during extended operation and contributes to long-term mechanical reliability under routine QC lab conditions.
- Sturdy aluminum-alloy chassis with non-slip rubber feet provides vibration damping and positional stability on benchtop surfaces—even during simultaneous multi-vessel agitation.
Sample Compatibility & Compliance
The HTR-03 supports common laboratory consumables including polypropylene and glass test tubes, Eppendorf-style microcentrifuge tubes (1.5–2.0 mL), and screw-cap vials up to 50 mL capacity. Its open-platform design allows rapid loading/unloading without lid interference. The device complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and meets CE marking requirements for electromagnetic compatibility (EMC Directive 2014/30/EU). While not certified for use in classified hazardous environments (e.g., ATEX Zone 1), it is suitable for general-purpose analytical labs operating under ISO/IEC 17025-accredited quality systems.
Software & Data Management
This unit operates via standalone hardware controls—no external software or PC interface is required. All operational parameters (speed setpoint, timer value, elapsed time) are displayed on a dual-digit LED screen with backlighting for ambient-lit or low-light bench environments. Though not equipped with USB or Ethernet connectivity, the timer function supports audit-ready documentation when integrated into SOP-driven workflows; timestamped logs can be manually recorded alongside sample IDs in LIMS or paper-based QA records. For laboratories requiring electronic record retention per FDA 21 CFR Part 11, external data capture via time-stamped video recording or integrated lab notebook platforms is recommended.
Applications
- Food safety testing: Homogenization of pesticide residue extracts prior to GC-MS or LC-MS analysis.
- Environmental monitoring: Uniform dispersion of suspended particulates in water or soil leachates for heavy metal quantification (e.g., EPA Method 200.8).
- Clinical diagnostics: Reconstitution of lyophilized calibrators and controls in immunochemistry assays.
- Pharmaceutical QC: Blending of excipients and active pharmaceutical ingredients (APIs) during early-stage formulation screening.
- Agricultural chemistry: Extraction of mycotoxins from grain matrices using acetonitrile/water solvents under AOAC-approved protocols.
FAQ
Is the HTR-03 compatible with 50 mL conical tubes?
Yes—the adjustable roller spacing accommodates tubes up to 18 mm in diameter and 120 mm in height, covering standard 50 mL polypropylene conical tubes.
Does the mixer include a safety interlock or lid sensor?
No. As a Class I open-platform vortex shaker, it does not feature automatic shutdown upon lid removal; users must follow standard lab PPE and procedural safeguards.
Can the timer be bypassed for continuous operation?
Yes—setting the timer to “0” enables indefinite run mode until manually stopped.
What maintenance is required for long-term performance?
Routine cleaning of the roller surface with 70% ethanol and periodic inspection of motor coupling integrity are sufficient; no scheduled lubrication or calibration is specified by the manufacturer.
Is technical support available outside mainland China?
Yes—authorized distributors provide multilingual documentation and remote troubleshooting assistance for international customers within 48 business hours.
