Overview
The Labotery ZQPZ-228A Precision Stackable Orbital Incubator Shaker is an engineered solution for laboratories requiring simultaneous temperature-controlled incubation and orbital agitation across multiple independent zones. Designed on the principle of forced-air convection combined with precise servo-driven orbital motion, it supports aerobic microbial growth, cell suspension culture, enzyme reaction kinetics, and biochemical assay development under tightly regulated thermal and mechanical conditions. Its modular three-tier stacking architecture enables scalable throughput without proportional footprint expansion—each tier operates as a thermally and dynamically isolated unit, allowing concurrent experiments at distinct temperatures (4–65 °C) and agitation speeds (10–300 rpm). The system integrates refrigeration via a non-CFC compressor and heating via PTC elements, regulated by a PID microprocessor with 0.1 °C resolution and ±0.5 °C uniformity (at 37 °C), meeting baseline performance expectations for GLP-compliant cell culture workflows.
Key Features
- Triple-layer stackable configuration with fully independent temperature and speed control per shelf—enabling parallel optimization of culture conditions.
- Orbital shaking mechanism driven by maintenance-free servo motor, delivering stable rotational output with ±1 rpm accuracy and programmable ramp profiles.
- IPX4-rated waterproof motor and dual-level liquid containment system: primary stainless-steel drip baffle beneath the chamber floor and secondary drain port in the lower housing compartment.
- 7-inch 16-bit true-color touchscreen interface supporting both fixed-setpoint and multi-step program modes; real-time curve plotting, screenshot capture, and timestamped data logging.
- Comprehensive safety architecture: door-interlocked motion stop, over-temperature cut-off with audible/visual alarm, automatic fault diagnostics, and operator-access encryption.
- Integrated UV germicidal lamp and adjustable LED illumination for sterile handling and visual inspection without opening the chamber.
- External ambient temperature sensor displayed on main UI to compensate for environmental drift during long-duration runs.
- USB port for data backup/export in CSV or graphical formats; optional thermal printer module and cloud-connected mobile application available as validated add-ons.
Sample Compatibility & Compliance
The ZQPZ-228A accommodates standard laboratory vessels including Erlenmeyer flasks (100–2000 mL), test tubes, and deep-well plates, secured via universal spring-loaded clamps or custom-configurable platforms. Its chamber design complies with ISO 13485-aligned manufacturing practices and incorporates features supporting audit-ready documentation: time-stamped event logs (power loss, door open, setpoint change), user-level access controls, and electronic signature-capable operation records. While not pre-certified to FDA 21 CFR Part 11, its data integrity framework—including immutable storage, checksum validation, and export traceability—facilitates internal validation for GMP-relevant applications such as bioprocess development and QC stability testing.
Software & Data Management
The embedded control firmware provides continuous acquisition of temperature, speed, and runtime parameters at 1-second intervals. All measurements are stored locally in non-volatile memory with cyclic overwrite protection and one-year retention capacity. Historical datasets can be exported via USB in CSV format for statistical analysis in MATLAB, JMP, or Python-based pipelines. Graphical outputs support PNG export and direct thermal printing (optional accessory). Audit trail functionality captures operator ID, timestamp, parameter changes, and system events—essential for laboratories maintaining ISO/IEC 17025 or CAP accreditation. Firmware updates are delivered via secure offline package installation to preserve regulatory continuity.
Applications
- Mammalian and insect cell suspension culture under controlled O2 exchange (enabled by pressure-balanced venting ports).
- Microbial fermentation studies requiring gradient temperature screening (e.g., E. coli, S. cerevisiae, B. subtilis).
- Enzyme activity assays where kinetic reproducibility depends on consistent shear input and thermal homogeneity.
- Antibiotic susceptibility testing and MIC determination using broth microdilution formats.
- Protein expression optimization in autoinduction media under varying agitation intensities.
- Environmental microbiology sample enrichment at sub-ambient temperatures (4–10 °C) with low-speed agitation.
FAQ
Can the ZQPZ-228A operate continuously for extended periods (e.g., >72 hours)?
Yes—the system is rated for unattended operation up to 999 hours 59 minutes, with built-in power-fail recovery that restores prior settings and resumes timing upon reconnection.
Is CO2 control available as a factory-installed option?
CO2 supplementation is supported through an optional retrofit kit, including gas inlet manifold, IR-based CO2 sensor, and modified control algorithm; validation documentation is provided separately.
What is the maximum allowable load per shelf when using 2 L flasks?
At 2000 mL × 12 configuration, total mass must not exceed 24 kg per shelf; dynamic imbalance correction is enforced by motor torque limiting below 100 rpm.
Does the system meet electromagnetic compatibility (EMC) requirements for laboratory environments?
It conforms to IEC 61326-1:2013 Class A emission limits and EN 61000-4-2/3/4/6 immunity standards, verified per manufacturer’s test report.
How is temperature uniformity verified during factory calibration?
Using nine NIST-traceable PT100 probes placed across the working volume per ISO 17025 procedures; results documented in the Certificate of Conformance shipped with each unit.
