Overview
The ZWY-211G is a high-capacity, tall-profile orbital shaker engineered for precision-controlled, large-volume cultivation in bioprocessing, fermentation, and upstream R&D environments. Designed on the principle of orbital (circular) motion with a 70 mm diameter oscillation amplitude, it delivers uniform mixing and oxygen transfer across heterogeneous culture volumes—critical for aerobic microbial growth, suspension cell expansion, and biochemical reaction kinetics. Its reinforced structural architecture supports stable operation at elevated speeds (30–150 rpm) under sustained thermal load, while the forced-air convection system ensures ±0.5 °C temperature stability at 37 °C and ≤±1 °C uniformity across the full 237 L chamber volume. The unit complies with general laboratory safety standards for electrical equipment (IEC 61010-1) and is suitable for GLP-compliant workflows where traceable environmental control and reproducible agitation profiles are required.
Key Features
- Orbital shaking mechanism with Φ70 mm amplitude—optimized for high-oxygen-demand cultures including E. coli, yeast, and mammalian suspension cells
- Intelligent PID microprocessor controller with LCD backlit display showing real-time setpoints and measured values for temperature and speed
- Parameter lock function to prevent accidental modification during extended runs; memory retention for up to 500 h of programmable timing
- Brushless AC induction motor—maintenance-free, torque-stable across speed range, rated for continuous operation
- Dual-stage thermal protection: independent overtemperature alarm with automatic power cutoff for both chamber and motor circuits
- Power-fail recovery mode—resumes prior operational parameters upon grid restoration without manual reconfiguration
- Soft-start acceleration profile minimizes shear stress on sensitive biological samples during initiation
- Electrostatically coated steel chassis with tempered glass viewing window; ergonomic front-access design with manual lid opening
Sample Compatibility & Compliance
The ZWY-211G accommodates standard laboratory vessels from 100 mL to 5000 mL (up to six 5-L flasks simultaneously), supporting common configurations such as baffled Erlenmeyer flasks, spinner flasks, and custom bioreactor bottles. Its internal dimensions (870 × 600 × 455 mm) and reinforced shelf (770 × 500 mm, single-tier) allow flexible layout arrangements without compromising airflow distribution. While not certified to ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, the device’s parameter logging capability (via optional RS-232/USB interface) enables integration into validated systems meeting GMP documentation requirements. It operates within ambient conditions of 5–25 °C and maintains chamber temperatures between 4–60 °C with ±0.1 °C resolution and ≤±0.5 °C fluctuation at setpoint.
Software & Data Management
The embedded controller records runtime data—including actual temperature, speed, and elapsed time—at user-defined intervals. Though native software is not included, ASCII-formatted logs can be exported via serial communication for post-processing in MATLAB, Python (Pandas), or LIMS platforms. For regulated environments, third-party validation packages support IQ/OQ protocols, audit trail generation, and electronic signature compliance when paired with compatible SCADA or ELN systems. Firmware updates are performed locally via USB port, ensuring long-term maintainability without cloud dependency.
Applications
This shaker serves critical roles in academic and industrial life science laboratories: bacterial and fungal fermentation scale-up; recombinant protein expression in shake-flask bioreactors; hybridoma and CHO cell line development; enzymatic assay optimization; and environmental microbiology studies requiring controlled aeration. Its thermal and mechanical consistency makes it particularly suited for DOE-based process characterization, media optimization trials, and comparability studies preceding bioreactor transfer. Regulatory submissions referencing shake-flask data (e.g., ICH Q5D, USP ) benefit from its documented repeatability and environmental fidelity.
FAQ
What is the maximum flask size supported on the ZWY-211G?
The unit accommodates up to six 5000 mL baffled flasks or fifteen 1000 mL flasks simultaneously, subject to balanced loading and recommended fill ratios.
Does the ZWY-211G include refrigeration?
No—it is a heating-only system (4–60 °C range). Ambient cooling must be provided externally if sub-ambient operation is required.
Is the shaker compatible with sterile workflow practices?
Yes—the stainless steel interior and smooth-welded corners support routine disinfection with 70% ethanol or approved sporicidal agents; however, autoclaving of the chamber is not permitted.
Can multiple ZWY-211G units be synchronized for parallel experiments?
Synchronization is not natively supported; each unit operates independently, though identical parameter sets can be replicated manually or via batch configuration scripts using external controllers.
What maintenance is required for long-term reliability?
Annual verification of temperature calibration and speed accuracy is recommended; no lubrication or brush replacement is needed due to the brushless motor design.
