Overview
The Zhongwei ZWYD-2402 Intelligent Stackable Dual-Chamber Orbital Shaker is an advanced laboratory platform engineered for precision-controlled, temperature-regulated orbital oscillation across two independent, vertically stackable chambers. It operates on the principle of single-axis orbital motion—generating uniform circular agitation (0–300 rpm, ±1 rpm accuracy) with continuously adjustable amplitude (Φ0–50 mm)—optimized for suspension culture integrity, oxygen transfer efficiency, and minimal shear stress in microbial, mammalian, and hybridoma cell cultures. Its dual-chamber architecture enables parallel yet isolated experimental conditions—ideal for comparative studies, process optimization, or staggered incubation protocols—while maintaining strict thermal uniformity (±1 °C at 37 °C) and stability (±0.1 °C fluctuation at 37 °C) via P.I.D.-controlled forced-air convection and dual-stage R134a refrigeration. Designed for continuous operation under ambient conditions of 10–35 °C, the system integrates microprocessor-based environmental scanning logic to monitor real-time deviations in temperature, speed, humidity (in optional configurations), and power supply—ensuring reproducible, GLP-aligned shaker performance in regulated life science environments.
Key Features
- Dual independent chambers (each 182 L capacity; internal dimensions 920 × 532 × 373 mm per layer) with fully segregated temperature and oscillation control
- P.I.D. microprocessor control with LCD backlit display showing setpoints and real-time values for temperature, speed, amplitude, time, and alarm status
- Multi-segment curve programming: up to 9 segments / 18 steps per chamber, supporting ramp-hold, stepwise temperature gradients, cyclic oscillation profiles, and fixed-parameter modes
- Comprehensive safety architecture: independent overtemperature cutoff (adjustable), over-speed protection, leakage current interruption, compressor overload safeguard, low-water-level detection with auto-refill, and power-failure recovery with parameter retention
- Brushless AC induction motor with soft-start acceleration profile—eliminating mechanical shock to sensitive cultures during startup
- Corrosion-resistant construction: electropolished stainless-steel interior, powder-coated steel exterior, tempered glass observation window, and removable stainless-steel trays with spring-loaded flask clamps
- Integrated RS-232 interface for external data logging and remote parameter synchronization; embedded thermal mini-printer for audit-ready hardcopy output
Sample Compatibility & Compliance
The ZWYD-2402 accommodates standard microbiological and bioprocess vessels—including Erlenmeyer flasks (50–5000 mL), baffled flasks, culture tubes, and multi-well plates—via interchangeable tray systems. Its orbital motion (Φ0–50 mm amplitude) ensures optimal mixing without foaming or splashing in low-viscosity aqueous media typical of bacterial fermentation, yeast propagation, and recombinant protein expression workflows. The system complies with general laboratory safety standards (IEC 61010-1) and supports traceability requirements through time-stamped parameter logging, password-protected configuration access, and non-volatile memory for protocol recall. While not certified to FDA 21 CFR Part 11 out-of-the-box, its RS-232 data export, parameter encryption, and audit trail-capable printer output facilitate integration into validated GxP environments when paired with compliant LIMS or ELN platforms.
Software & Data Management
No proprietary software is bundled; however, the RS-232 serial interface enables seamless integration with third-party laboratory data acquisition systems (e.g., LabVIEW, MATLAB, or custom Python scripts) for real-time monitoring and automated reporting. All user-defined programs—including temperature ramps, speed sequences, and dwell times—are stored in non-volatile memory and persist through power cycles. The embedded thermal printer provides immediate documentation of start/stop timestamps, setpoint history, and active alarm events—critical for method verification and batch record completeness. Parameter encryption prevents unauthorized modification, while “parameter memory” and “temperature calibration offset” functions support instrument qualification and routine maintenance compliance.
Applications
This shaker serves core workflows in academic research, pharmaceutical development, and quality control laboratories—including aerobic bacterial culture (E. coli, Bacillus spp.), fungal fermentation, hybridoma expansion, enzyme kinetics assays, solubility screening, and buffer equilibration. Its dual-chamber design is particularly valuable for DOE (Design of Experiments) setups—such as evaluating temperature–agitation interactions on monoclonal antibody titer—or for running control vs. test conditions simultaneously without cross-contamination risk. In biomanufacturing settings, it supports seed train scalability studies and media optimization under tightly controlled thermal–mechanical stress profiles aligned with ICH Q5C stability guidelines.
FAQ
Does the ZWYD-2402 support CO₂ control?
No—the ZWYD-2402 model does not include CO₂ regulation. For CO₂-enabled applications, refer to the ZWYD-C series variants.
What is the maximum flask size supported per chamber?
Each chamber accommodates up to four 2 L baffled flasks or eight 1 L flasks using the standard stainless-steel tray configuration.
Is the refrigeration system frost-free?
Yes—the dual-stage R134a cooling system operates in frost-free mode with intelligent defrost cycling to maintain uninterrupted temperature stability.
Can both chambers run at different temperatures and speeds simultaneously?
Yes—each chamber has fully independent PID controllers, enabling concurrent but distinct temperature (4–60 °C) and oscillation (0–300 rpm) profiles.
What calibration documentation is provided?
A factory calibration certificate covering temperature uniformity, speed accuracy, and alarm threshold verification is included with shipment. NIST-traceable recalibration services are available upon request.
