ZWY-322C Single-Layer High-Amplitude High-Capacity Orbital Shaker

Overview

The ZWY-322C Single-Layer High-Amplitude High-Capacity Orbital Shaker is an industrial-grade laboratory shaker engineered for continuous, stable, and reproducible orbital motion in controlled ambient environments. Designed for integration into centralized incubation rooms or shared facility spaces, it operates via eccentric-drive orbital oscillation—generating uniform circular motion with a fixed 50 mm diameter orbit (Φ50). This mechanical configuration ensures consistent mixing, suspension, and aeration across large-volume culture vessels (e.g., 5–10 L baffled flasks), minimizing shear stress while maximizing oxygen transfer efficiency—critical for aerobic microbial cultivation, recombinant protein expression, and cell-based bioprocess development. Unlike compact benchtop units, the ZWY-322C features a reinforced cast-iron chassis and die-cast aluminum structural components, supporting sustained operation under full load at speeds ranging from 30 to 300 rpm with ±1 rpm speed stability. Its natural convection design makes it suitable for use inside temperature-stabilized rooms (5–50 °C), eliminating internal heating elements that could interfere with external environmental control.

Key Features

• Brushless AC induction motor with maintenance-free operation, delivering constant torque and speed across the full 30–300 rpm range
• PID-controlled microprocessor system with environmental scanning capability, enabling real-time adaptive regulation of oscillation parameters
• Backlit LCD interface displaying setpoints and real-time values for speed, timer, and operational status
• Parameter encryption function to prevent unauthorized modification—essential for GLP-compliant workflows and multi-user facilities
• Power-fail recovery mode: automatically resumes pre-interruption settings upon restoration of AC supply
• Soft-start acceleration circuitry ensures gradual ramp-up to target speed, protecting fragile cultures and minimizing flask slippage
• One-piece precision-machined platform (920 × 640 mm) with non-slip rubber matting and universal flask clamping compatibility
• Electrostatically applied powder-coated steel enclosure for corrosion resistance and long-term structural integrity

Sample Compatibility & Compliance

The ZWY-322C accommodates standard Erlenmeyer flasks (up to 10 L), Fernbach flasks, and custom bioreactor vessels mounted directly on its single large-format tray. Its orbital motion profile meets common requirements for bacterial growth (e.g., E. coli, Bacillus spp.), yeast fermentation (e.g., S. cerevisiae), and mammalian suspension cultures where gentle yet thorough mixing is required. The device complies with IEC 61000-6-3 (EMC emission standards) and IEC 61010-1 (safety requirements for laboratory equipment). While not intrinsically rated for use inside CO₂ incubators or humidified chambers, its natural convection architecture enables safe deployment in ISO Class 7/8 cleanroom-adjacent environments when paired with external temperature and humidity monitoring per ISO 14644-1. All firmware operations support audit trail readiness for FDA 21 CFR Part 11–aligned documentation protocols when integrated with validated LIMS or ELN systems.

Software & Data Management

The ZWY-322C operates as a standalone hardware platform with no embedded operating system or network interface. All operational parameters—including speed, timer duration, and alarm thresholds—are configured locally via the front-panel LCD and stored in non-volatile memory. The parameter memory function retains up to five user-defined protocols, reducing repetitive setup in high-throughput labs. For traceability, the unit logs power-on cycles and timer-initiated events internally; however, external data logging requires integration with third-party RS-232 or analog output modules (sold separately). When deployed in regulated environments (e.g., pharmaceutical QC labs), users may implement manual logbooks or electronic batch records aligned with USP , ISO/IEC 17025, or EU GMP Annex 11 requirements—leveraging the device’s parameter encryption and auto-restart features to enforce procedural consistency.

Applications

This shaker serves core functions across academic, clinical, and industrial life science laboratories. In upstream bioprocessing, it supports seed train expansion and small-scale fermentation optimization prior to bioreactor scale-up. In molecular biology labs, it facilitates plasmid amplification, phage propagation, and enzymatic reaction mixing under defined aeration conditions. Regulatory-compliant applications include media preparation validation (per USP ), antimicrobial susceptibility testing (AST) broth agitation, and immunological assay plate coating steps requiring uniform liquid distribution. Environmental microbiology labs utilize the ZWY-322C for waterborne pathogen enrichment (e.g., Legionella culture per ISO 11731) and soil extract homogenization. Its robust construction also supports long-duration stability studies (e.g., 500-hour continuous runs) in formulation development and excipient compatibility screening.

FAQ

Is the ZWY-322C compatible with refrigerated or heated enclosures?
No—the unit relies on natural convection and is designed for use in externally temperature-controlled rooms (5–50 °C). It lacks internal heating/cooling elements and should not be placed inside insulated cabinets without verified airflow clearance.
Can multiple ZWY-322C units be synchronized for parallel operation?
Not natively. Each unit operates independently with no master-slave or network synchronization capability. Synchronization must be achieved externally via programmable logic controllers (PLCs) or time-based relay triggers.
What safety certifications does the ZWY-322C hold?
It conforms to IEC 61010-1 (Safety of Electrical Equipment for Measurement, Control, and Laboratory Use) and IEC 61000-6-3 (EMC Emission Standard). CE marking is available upon request for EU shipment compliance.
Does the shaker support flask clamps for varying neck diameters?
Yes—the standard tray accepts universal adjustable clamp sets (sold separately) compatible with 24–50 mm neck diameters, including ISO metric and ASTM-standard flask geometries.
Is firmware update capability available?
Firmware is factory-programmed and not field-upgradable. Functional updates are implemented only through hardware revision (e.g., ZWY-322C → next-generation model) and require formal technical documentation from the authorized distributor.
