Overview
The Labotery ZQPZ-228A Precision Stackable Orbital Incubator Shaker is an engineered solution for controlled microbial growth, cell culture expansion, enzyme kinetics, and biochemical reaction studies requiring simultaneous temperature regulation and orbital agitation. It operates on the principle of horizontal orbital shaking—generating consistent, low-shear fluid motion ideal for aerobic suspension cultures—while maintaining precise thermal environments across a broad operational range (4–65°C). Its stackable three-layer architecture enables modular laboratory scalability without compromising footprint efficiency, supporting independent parameter control per layer to accommodate heterogeneous experimental conditions within a single unit. Designed for compliance-driven life science workflows, the ZQPZ-228A integrates hardware-level safeguards—including triple-stage liquid containment, IPX4-rated motor protection, and door-actuated motion interlock—to meet GLP-aligned operational integrity requirements in academic, pharmaceutical, and contract research settings.
Key Features
- Triple-layer stackable configuration with individual temperature and speed control per shelf—enabling parallel experiments under divergent conditions.
- Orbital motion driven by high-efficiency servo motor with ±1 rpm accuracy and maintenance-free operation over extended duty cycles.
- Robust triple liquid protection system: (1) stainless steel drip shield beneath chamber floor; (2) sealed, corrosion-resistant waterproof motor; (3) rear-mounted drainage port for incidental spill evacuation.
- 7-inch 16-bit true-color touchscreen interface with intuitive navigation, real-time data visualization, and dual-mode control (constant-value and multi-step programmable).
- PID-based microprocessor temperature control with 0.1°C resolution and ≤±0.5°C uniformity at 37°C, validated under ISO 17025-aligned test conditions (20°C ambient, 50% RH).
- Integrated UV-C germicidal lamp and adjustable LED illumination for sterile handling and visual monitoring without opening the chamber.
- Environmental temperature sensor mounted externally to compensate for ambient drift—critical for reproducible incubation in non-climate-controlled labs.
- Comprehensive data management: on-device storage of 12 months’ continuous logging, USB export (CSV/PNG), real-time curve printing, and encrypted user-access controls compliant with FDA 21 CFR Part 11 audit trail prerequisites.
Sample Compatibility & Compliance
The ZQPZ-228A accommodates standard Erlenmeyer flasks (100–3000 mL), culture tubes, and deep-well plates via interchangeable clamping fixtures. Its 26 mm and 50 mm orbit options support both high-density microbial propagation and low-shear mammalian cell suspension protocols. Chamber geometry—featuring rounded interior corners and smooth electropolished stainless steel surfaces—ensures cleanability per USP analytical instrument qualification guidelines. All electrical components conform to IEC 61010-1 safety standards for laboratory equipment. The unit’s thermal performance validation protocol aligns with ASTM E2500-13 (Guide for Specification, Design, and Verification of Pharmaceutical and Biopharmaceutical Manufacturing Systems) and supports IQ/OQ documentation packages for GMP-regulated facilities.
Software & Data Management
The embedded control firmware supports two operational modes: constant-value (single-setpoint) and programmable (up to 20 segments with ramp/soak profiles). Real-time graphs display temperature, speed, and elapsed time synchronously; historical trends are archived with timestamped metadata. Data export functions include CSV for LIMS integration and PNG for regulatory submission appendices. USB backup preserves full session logs—including alarm events, parameter changes, and user logins—facilitating traceability during internal audits or regulatory inspections. Optional remote monitoring via secure HTTPS-enabled mobile application extends operational oversight beyond the lab boundary while preserving network isolation protocols.
Applications
- Microbial cultivation (E. coli, yeast, Bacillus spp.) under aerobic or microaerophilic conditions.
- Recombinant protein expression in shake-flask bioreactors with temperature-inducible promoters (e.g., pET systems).
- Antibiotic susceptibility testing and minimum inhibitory concentration (MIC) assays per CLSI M07-A10 standards.
- Enzyme activity profiling across thermal gradients (e.g., thermostability screening of engineered lipases).
- Stem cell expansion and organoid formation requiring precise oxygenation and shear stress modulation.
- Biodegradation studies of xenobiotics in liquid-phase enrichment cultures.
FAQ
What is the maximum flask size supported per shelf?
The ZQPZ-228A accommodates up to thirty 3000 mL flasks or one hundred four 100 mL flasks per shelf, depending on selected clamp configuration.
Does the unit comply with FDA 21 CFR Part 11 requirements?
Yes—the system provides electronic signature capability, audit-trail logging, and role-based access control when configured with password-protected administrator mode.
Can the shaker operate continuously for 999 hours?
Yes; the timer supports uninterrupted runs up to 999 h 59 min, with automatic restart after power recovery enabled by non-volatile memory retention.
Is CO₂ supplementation available as a factory-installed option?
CO₂ integration is offered as an optional upgrade kit, including mass flow controller, gas inlet manifold, and recalibrated humidity compensation algorithms.
How is temperature uniformity verified during installation qualification?
Uniformity is assessed using nine calibrated PT100 probes positioned per ISO 17025-recommended grid pattern; results are documented in the provided IQ/OQ report template.
