Overview
The ZiQi XW-80A Vortex Mixer is a compact, benchtop orbital shaker engineered for rapid and reproducible homogenization of small-volume samples in life science and clinical laboratories. It operates on the principle of orbital motion—generating controlled circular displacement of the platform at a fixed frequency—to induce vigorous vortex formation within tubes and vials. This mechanism ensures efficient mixing of heterogeneous systems including liquid–liquid solutions, liquid–solid suspensions, and fine powdered solids without requiring mechanical clamping or adjustable speed ramps. Designed for routine use in molecular biology, immunoassays, cell culture preparation, and diagnostic sample processing, the XW-80A delivers consistent performance under continuous operation while maintaining low thermal load and minimal acoustic emission—critical attributes for shared lab environments and noise-sensitive facilities.
Key Features
- Stable 2800 rpm orbital motion with high mechanical reproducibility across extended duty cycles
- Brushless AC motor with imported components, delivering quiet operation (<45 dB(A) at 1 m) and extended service life
- Monolithic ABS housing fabricated via precision injection molding—chemically resistant to common laboratory solvents, dilute acids and bases, and mechanically robust against incidental impact
- Non-painted surface finish eliminates flaking, chipping, or VOC off-gassing—supporting ISO 14644-compliant cleanroom-adjacent workflows
- 100 mm diameter elastomeric foam platform provides secure grip for 0.2–50 mL tubes, microcentrifuge tubes, PCR strips, and small Erlenmeyer flasks; accommodates both conical and round-bottom vessels
- Fixed-speed architecture optimized for simplicity, reliability, and regulatory traceability—no firmware, no calibration drift, no user-configurable parameters requiring validation
Sample Compatibility & Compliance
The XW-80A supports standard ANSI/SLAS-format tubes (including 1.5 mL and 2.0 mL microcentrifuge tubes), snap-cap vials, and low-profile PCR plates. Its vibration profile is compatible with viscous buffers (e.g., glycerol-containing lysis reagents), dense cell pellets, and lyophilized reagent resuspension protocols. While not certified to IEC 61010-1 or UL 61010B as a standalone safety-certified device, its electrical design complies with GB 4793.1–2007 (Chinese equivalent of IEC 61010-1), and its material composition meets RoHS Directive 2011/65/EU requirements for restricted substances. For GLP/GMP-aligned labs, the absence of programmable logic or data logging simplifies qualification (IQ/OQ) and reduces documentation burden during audit preparation.
Software & Data Management
The XW-80A is a fully analog, hardware-only instrument with no embedded software, firmware, or digital interface. It requires no driver installation, network configuration, or cybersecurity controls. All operational parameters—including speed, runtime, and power state—are controlled manually via a single toggle switch. This architecture eliminates risks associated with software obsolescence, firmware corruption, or time-stamp synchronization failures. For laboratories operating under FDA 21 CFR Part 11 or Annex 11 requirements, the lack of electronic records means no audit trail generation is needed—reducing validation scope and supporting straightforward equipment qualification using basic functional testing per SOP-LAB-VM-001.
Applications
- Rapid resuspension of DNA/RNA pellets post-ethanol precipitation
- Homogenization of bacterial lysates prior to centrifugation
- Uniform dispersion of antibody–bead conjugates in immunoprecipitation workflows
- Mixing of multi-component master mixes for qPCR and NGS library preparation
- Reconstitution of lyophilized enzyme standards and calibrators
- Pre-analytical agitation of whole blood or serum samples to prevent phase separation prior to aliquoting
FAQ
Is the XW-80A suitable for mixing viscous samples such as glycerol stocks or agarose solutions?
Yes—the orbital motion generates sufficient shear to initiate vortexing in fluids up to ~150 mPa·s viscosity when loaded in standard 1.5 mL tubes. For higher-viscosity media, pre-warming or dilution is recommended.
Can the unit be operated inside a cold room or refrigerated incubator?
It is rated for ambient operation between 5 °C and 40 °C and relative humidity ≤80% non-condensing. Prolonged exposure below 10 °C may affect foam platform elasticity and motor startup torque.
Does the mixer include tube holders or adapters?
No—platform design relies on friction-based retention. Optional universal silicone inserts (sold separately) are available for enhanced stability with low-volume tubes.
What maintenance is required?
None beyond periodic wiping of the platform with 70% ethanol. The sealed motor and ABS housing require no lubrication or internal servicing over its expected 5+ year service life.
Is CE marking or FDA listing applicable?
The device is not CE-marked or FDA-listed, as it falls outside the scope of IVDR, MDR, or 21 CFR 807 due to its general-purpose laboratory function and absence of diagnostic claims.
