Overview
The ZiQi ZQTR-080 Rolling-Rocking Mixer is an engineered laboratory device designed for gentle yet effective homogenization of sensitive biological and viscous samples—particularly whole blood, serum, plasma, coagulation assays, cell suspensions, and heterogeneous liquid-solid mixtures. Unlike vortex or orbital shakers that apply high-shear forces, this instrument operates on a dual-axis motion principle: simultaneous rolling (rotational displacement around horizontal axes) and rocking (oscillatory tilting about a central pivot), generating laminar, low-turbulence flow patterns ideal for preserving cellular integrity and preventing foaming or denaturation. Its core mechanism avoids centrifugal separation while ensuring uniform re-suspension of settled particles—critical for downstream analytical consistency in clinical chemistry, transfusion medicine, and hematology workflows.
Key Features
- Combined rolling and rocking motion: Enables thorough mixing of high-viscosity fluids and sediment-prone suspensions without shear-induced damage or bubble formation.
- Seven precision-aligned rollers: Optimized spacing accommodates standard tube formats—including 12 × 75 mm, 13 × 100 mm, 16 × 100 mm, and 16 × 150 mm culture tubes—as well as microcentrifuge tubes (0.5–15 mL) and glass vials.
- Adjustable roller length option: Modular roller extension capability allows users to increase sample capacity per run while maintaining mechanical stability and motion fidelity.
- Brushless DC geared motor: Delivers consistent torque across the full 20–80 rpm range, with minimal thermal drift and acoustic emissions (<45 dB(A) at 1 m), supporting unattended overnight operation in shared lab environments.
- Durable ABS housing: Chemically resistant, non-porous, and static-dissipative; rated for continuous duty under ISO 13485-aligned manufacturing conditions.
- Analog speed scale with tactile feedback: Provides intuitive, calibration-stable speed selection—no software dependency or firmware updates required.
Sample Compatibility & Compliance
The ZQTR-080 is validated for use with evacuated blood collection tubes (EDTA, citrate, heparin), serum separator tubes (SST), urine containers, and polymerase chain reaction (PCR) master mix vessels. It complies with general safety requirements outlined in IEC 61010-1:2010 (Safety of Laboratory Equipment) and meets electromagnetic compatibility (EMC) standards per EN 61326-1:2013. While not certified for GMP or FDA 21 CFR Part 11 environments out-of-the-box, its mechanical simplicity, absence of embedded memory or network interfaces, and traceable manufacturing origin support integration into GLP-compliant workflows when paired with documented operational qualification (OQ) protocols.
Software & Data Management
This mixer operates as a standalone analog instrument with no onboard digital control system, software interface, or data logging functionality. All operational parameters—including speed setting, runtime, and motion mode—are manually selected and visually confirmed via the calibrated analog scale. This architecture eliminates cybersecurity risks, firmware obsolescence, and validation overhead associated with digital controllers—making it suitable for regulated laboratories where audit trails are maintained externally (e.g., via electronic lab notebooks or LIMS entries). No drivers, cloud services, or proprietary applications are required.
Applications
- Clinical diagnostics: Homogenizing anticoagulated whole blood prior to hematocrit measurement, CBC analysis, or coagulation factor assays (e.g., PT/INR, aPTT).
- Blood bank operations: Ensuring uniform distribution of additives in stored RBC units and platelet concentrates before leukoreduction or pathogen reduction processing.
- Research laboratories: Re-suspending cryopreserved cell pellets, preparing agarose gels, and conditioning hydrogel-based scaffolds for tissue engineering studies.
- Pharmaceutical QA/QC: Mixing viscosity-modified formulations (e.g., suspensions, emulsions) during stability testing per ICH Q5C guidelines.
- Environmental microbiology: Homogenizing soil-water slurries and biofilm-containing wastewater samples prior to membrane filtration or MPN enumeration.
FAQ
Is the ZQTR-080 suitable for mixing serum separator tubes (SSTs)?
Yes—the low-shear rolling-rocking motion prevents premature clot disruption and maintains gel barrier integrity during pre-centrifugation mixing.
Can the unit be operated inside a cold room or incubator?
It is rated for ambient operation between 5 °C and 40 °C and relative humidity ≤80% non-condensing; extended low-temperature use requires verification of motor lubricant performance and ABS dimensional stability.
Does the mixer include overload or thermal protection?
Yes—the integrated DC motor driver incorporates automatic current limiting and thermal cutoff circuitry compliant with IEC 60335-1 Annex BB.
What maintenance is required?
No scheduled maintenance is specified; periodic visual inspection of roller alignment and cleaning of the ABS chassis with 70% isopropyl alcohol is recommended.
Is CE marking applied to this device?
CE marking is not affixed; however, technical documentation confirms conformity with essential requirements of the Low Voltage Directive (2014/35/EU) and EMC Directive (2014/30/EU) for self-declaration by end-user institutions.
