Zhicheng ZWY-100H Classic Multi-Amplitude Orbital Shaker

Overview

The Zhicheng ZWY-100H Classic Multi-Amplitude Orbital Shaker is an engineered platform for precise, reproducible orbital agitation in life science laboratories. Designed around a single-axis eccentric cam drive system, it delivers true continuous amplitude modulation—enabling users to dynamically adjust oscillation diameter from 0 to 50 mm while maintaining stable rotational frequency across the full 30–400 rpm range. This dual-parameter control architecture directly addresses oxygen transfer rate (OTR) variability in microbial cultures, suspension cell expansions, and enzymatic assays where dissolved oxygen concentration is a critical process variable. Unlike fixed-amplitude shakers, the ZWY-100H supports both low-speed, high-amplitude orbital motion for gentle mixing and high-speed, low-amplitude agitation for enhanced aeration—without mechanical reconfiguration. Its forced convection temperature control system (RT+5 to 60 °C, ±0.1 °C stability at 37 °C) ensures thermal uniformity across the 340 × 370 mm stainless-steel shelf, making it suitable for incubated shaking applications requiring simultaneous thermal and mechanical precision.

Key Features

• Continuously variable orbital amplitude (Φ0–50 mm) via precision eccentric cam mechanism—enabling fine-tuned control over shear stress and mass transfer rates
• PID microprocessor controller with environmental scanning algorithm for real-time compensation of ambient fluctuations and load-dependent thermal drift
• LCD backlit display showing setpoints and real-time values for temperature, speed, amplitude, and remaining time—with password-protected parameter locking
• Soft-start acceleration circuitry that eliminates torque shock during motor startup, ensuring sample integrity during inoculation-sensitive protocols
• Brushless AC induction motor with constant torque delivery across the entire speed range—no carbon brushes, zero maintenance, and extended service life
• Dual safety architecture: independent overtemperature cutoff (motor winding & chamber), audible/visual alarm, and automatic power isolation upon fault detection
• Power failure recovery function: resumes operation at pre-interruption settings—including elapsed time, temperature, and speed—after grid restoration
• Ergonomic design with electrostatically coated steel chassis, tempered glass viewing window, and vibration-damped feet for stable benchtop operation

Sample Compatibility & Compliance

The ZWY-100H accommodates standard laboratory vessels up to 1000 mL per position, supporting configurations including 18 × 50 mL tubes, 10 × 250 mL Erlenmeyer flasks, or 4 × 1000 mL bottles on its single-tier platform. Its chamber geometry (445 × 450 × 315 mm internal) permits use of stackable multi-layer racks for high-throughput screening. The device complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and meets EMC requirements per EN 61326-1:2013. While not certified for GLP/GMP environments out-of-the-box, its parameter logging, user access control, and audit-ready timer functionality support alignment with ISO/IEC 17025 quality management systems when integrated into validated workflows. Temperature and speed calibration points are traceable to NIST-certified references via optional third-party certification services.

Software & Data Management

The ZWY-100H operates autonomously via embedded firmware—no external PC or proprietary software is required for routine operation. All setpoints and real-time parameters are stored in non-volatile memory with timestamped runtime logs accessible via the front-panel interface. For integration into centralized lab data systems, RS-232 serial output (optional adapter) enables ASCII-formatted telemetry transmission—including temperature, speed, amplitude, timer status, and alarm events—to LIMS or ELN platforms. The device supports configurable data export intervals (1–60 min) and includes checksum validation to ensure transmission integrity. Though not natively 21 CFR Part 11 compliant, its parameter lockout, operator ID prompts (via optional keypad), and immutable session logs provide foundational elements for regulated environments undergoing qualification (IQ/OQ/PQ).

Applications

• Bacterial and yeast culture expansion under controlled aeration and thermal conditions (e.g., E. coli, S. cerevisiae)
• Enzyme kinetics studies requiring defined shear environments and consistent O₂ supply
• Cell suspension culture of mammalian and insect lines in serum-free or low-serum media
• Molecular biology protocols including plasmid preparation, phage propagation, and hybridization buffer equilibration
• Environmental microbiology assays involving soil slurry agitation or biofilm disruption studies
• Quality control testing of biopharmaceutical intermediates where mixing homogeneity impacts analytical reproducibility

FAQ

What is the maximum flask size supported on the ZWY-100H platform?
The unit accommodates up to four 1000 mL Erlenmeyer flasks simultaneously—or nine 500 mL flasks—within its 340 × 370 mm shelf area.
Does the shaker support remote monitoring or network connectivity?
It features RS-232 serial output for basic telemetry; Ethernet or Wi-Fi connectivity is not built-in but may be added via third-party industrial gateways compatible with Modbus RTU.
Is calibration documentation included with shipment?
Factory calibration certificates for temperature and speed are provided. NIST-traceable recalibration services are available through authorized Zhicheng service partners.
Can the amplitude be changed during active operation?
Yes—amplitude adjustment is fully dynamic and does not require pausing or resetting the shaker.
What safety certifications does the ZWY-100H hold?
It conforms to IEC 61010-1:2010 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and EN 61326-1:2013 (EMC for Laboratory Equipment).
