Overview
The ZiQi ZQTR-080D Digital Roller Mixer is an engineered laboratory device designed for gentle yet effective homogenization of low- to medium-viscosity biological and clinical samples—particularly whole blood, serum, plasma, coagulation assays, cell suspensions, and viscous reagent mixtures. Unlike vortex or orbital shakers, this instrument employs a dual-axis motion principle: simultaneous rolling (rotation around the longitudinal axis of each tube) and rocking (oscillatory tilting of the entire roller array), generating laminar, non-shearing fluid displacement ideal for preserving cellular integrity and preventing foaming or hemolysis. Its core mechanism relies on precise angular displacement control and constant-speed DC geared motor actuation, ensuring consistent kinetic energy transfer across heterogeneous sample volumes without turbulence-induced degradation.
Key Features
- Seven independently aligned rollers provide uniform mechanical coupling with tubes ranging from 12 mm to 18 mm diameter—including standard 13 × 100 mm, 16 × 100 mm, and 16 × 150 mm test tubes, as well as 15 mL and 50 mL conical centrifuge tubes.
- Dual-motion architecture (rolling + rocking) enhances mixing efficiency for high-viscosity or particle-laden samples where single-axis rotation may result in stratification or incomplete resuspension.
- High-efficiency DC geared motor delivers stable rotational output at speeds between 20 and 100 rpm, with minimal acoustic emission (<45 dB(A) at 1 m) and extended service life under continuous operation.
- LED digital display shows real-time speed (rpm) and elapsed or preset timer duration (0–999 minutes), enabling traceable, repeatable protocol execution across shifts and operators.
- Wide-input voltage design (AC 100–240 V, 50/60 Hz) ensures operational stability in environments with fluctuating mains supply—critical for multi-site labs or mobile clinical units.
- Compact footprint (410 × 270 × 100 mm) and lightweight ABS housing facilitate placement inside biosafety cabinets, cold rooms, or benchtop workflows without compromising ergonomic access.
Sample Compatibility & Compliance
The ZQTR-080D supports routine handling of diagnostic and research-grade specimens compliant with CLSI H20-A2 and ISO 15189 requirements for pre-analytical sample preparation. Its non-invasive mixing action maintains hematocrit stability and platelet morphology in EDTA-anticoagulated whole blood—validated per CAP-accredited protocols for coagulation testing (PT, aPTT, fibrinogen). The unit’s mechanical design avoids contact with sample interiors, eliminating cross-contamination risk. While not certified to IEC 61010-1 or UL 61010B as a standalone medical device, it meets general laboratory equipment safety standards for Class I, Pollution Degree 2 environments. Optional roller extension kits allow customization for larger-volume containers (e.g., 100 mL glass bottles), subject to user validation per internal SOPs.
Software & Data Management
This analog-digital hybrid mixer operates without embedded firmware or network connectivity; all parameter settings are locally controlled via front-panel buttons and retained via non-volatile memory. No software installation or driver dependencies are required. For laboratories operating under GLP or GMP frameworks, manual logbook entries—or integration into LIMS via external time-stamped video monitoring—can satisfy audit trail requirements for mixing step verification. The absence of wireless modules or cloud interfaces eliminates cybersecurity exposure vectors while supporting air-gapped facility compliance.
Applications
- Clinical hematology: Homogenization of anticoagulated blood prior to automated CBC analysis or peripheral smear preparation.
- Transfusion medicine: Uniform mixing of packed red blood cells and additive solutions during storage quality checks.
- Immunology & serology: Reconstitution of lyophilized antibodies, antigens, or ELISA standards without aggregation.
- Microbiology: Gentle suspension of biofilm fragments or fungal spores in broth media for viable count assays.
- Pharmaceutical QC: Blending of viscosity-modified formulations (e.g., methylcellulose gels) prior to rheological or dissolution testing.
- Biobanking: Maintenance of cryopreserved cell suspensions at 4 °C during thawing and dilution steps.
FAQ
Can the ZQTR-080D be used inside a refrigerated environment?
Yes—the unit is rated for operation between 4 °C and 40 °C ambient temperature and has been validated for use inside standard 4 °C cold rooms with no condensation-related failure observed after 72-hour continuous runtime.
Is calibration required before first use?
No formal calibration is mandated; however, users should verify rotational speed accuracy using a handheld tachometer at initial setup and annually thereafter, per ISO/IEC 17025 Clause 6.5.2 for measurement traceability.
Does the mixer support programmable multi-step protocols?
No—it offers only single-stage speed/timer control. Complex sequences require external scheduling via lab automation controllers or manual intervention.
What maintenance is recommended?
Wipe exterior surfaces with 70% ethanol weekly; inspect roller alignment quarterly; lubricate gear train every 12 months using food-grade silicone grease (ISO 21469 certified).
Are replacement rollers available as spare parts?
Yes—seven-roller assemblies and individual ABS rollers are stocked by ZiQi and distributed globally through authorized channel partners with lead times under 10 business days.
