Zhongwei ZWY-211C High-Capacity Full-Temperature Orbital Incubator Shaker

Overview

The Zhongwei ZWY-211C High-Capacity Full-Temperature Orbital Incubator Shaker is an engineered platform for scalable bioprocess development and high-throughput cultivation under precisely controlled thermal and mechanical conditions. Designed around orbital (circular) motion dynamics—governed by a balanced multi-dimensional drive system—the instrument delivers consistent, low-shear mixing ideal for aerobic microbial growth, suspension cell culture, enzyme assays, and biochemical reaction kinetics. Its full-temperature range (4–60 °C), enabled by integrated refrigeration and forced convection airflow, ensures stable thermal environments across physiological, mesophilic, and thermotolerant operating regimes. The unit’s 256 L chamber volume and elevated internal height (465 mm) accommodate up to six 5 L Erlenmeyer flasks—making it uniquely suited for pilot-scale fermentation, seed train expansion, and GMP-aligned process qualification studies where volumetric scalability and parameter reproducibility are critical.

Key Features

• PID-controlled microprocessor with environmental scanning logic ensures dynamic compensation for ambient fluctuations and load-dependent thermal inertia
• LCD backlit display presents real-time values for temperature, speed, elapsed time, and remaining timer duration—alongside user-defined setpoints
• Parameter encryption lock prevents unauthorized modification of operational configurations—supporting audit-ready workflows in regulated environments
• Non-volatile memory retains all active settings after power loss; auto-restart functionality resumes pre-interruption protocols without manual reconfiguration
• Gradual acceleration ramp control minimizes mechanical shock to sensitive cultures during startup—preserving cell viability and metabolic synchrony
• Brushless AC induction motor delivers maintenance-free operation over extended duty cycles, with constant torque output across the full 30–300 rpm range
• Robust electrostatically coated steel chassis and tempered glass viewing window support long-term structural integrity and visual process monitoring
• Dual-stage safety architecture includes independent over-temperature cutoff, motor thermal protection, and audible/visual fault alerts compliant with IEC 61010-1

Sample Compatibility & Compliance

The ZWY-211C accommodates standard laboratory glassware—including baffled and non-baffled Erlenmeyer flasks (100–5000 mL), Fernbach vessels, and custom bioreactor bottles—via its reinforced 920 × 500 mm stainless-steel shelf. Flask distribution follows ISO 27874-compliant spacing guidelines to ensure uniform air exchange and convective heat transfer across the entire working volume. The system meets essential requirements for GLP-compliant microbiological testing (per ISO/IEC 17025:2017 Annex A.3), supports USP / microbial enumeration validation, and aligns with FDA 21 CFR Part 11 data integrity expectations when paired with validated electronic log export (see Software section). All thermal performance specifications—including uniformity (≤±1 °C at 37 °C) and stability (≤±0.1 °C)—are verified per ASTM E145-22 Annex A3 calibration protocols using NIST-traceable PT100 sensors.

Software & Data Management

While the ZWY-211C operates as a standalone hardware platform with embedded firmware, it supports external data capture via RS-485 serial interface (Modbus RTU protocol). When integrated with third-party SCADA or LIMS systems—including LabVantage, Thermo Fisher SampleManager, or custom Python-based acquisition tools—users can log timestamped temperature, speed, and runtime parameters at configurable intervals (1–60 s resolution). Audit trails generated through such integrations include operator ID, parameter change history, and event timestamps—enabling compliance with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available). Firmware updates are performed via secure USB dongle; version history and checksum verification are retained in device memory for regulatory review.

Applications

• Seed train expansion and inoculum preparation for upstream bioprocessing (mammalian, bacterial, yeast)
• Optimization of dissolved oxygen transfer rates (k_La) in aerobic cultivations
• Long-duration stability studies of therapeutic proteins under thermal stress conditions
• Enzyme kinetic profiling across defined temperature gradients (e.g., Q₁₀ analysis)
• Environmental microbiology assays requiring precise incubation of water, soil, or clinical isolates
• Preparation of competent cells, phage lysates, and plasmid propagation batches
• Food safety testing per ISO 6579 (Salmonella) and ISO 11290 (Listeria) enrichment protocols
• Agricultural biocontrol strain propagation and formulation development

FAQ

What is the maximum flask size supported on the ZWY-211C shelf?
The unit accommodates up to six 5000 mL Erlenmeyer flasks simultaneously—enabled by its 465 mm internal height and reinforced shelf design.
Does the system support programmable ramp-and-soak temperature profiles?
No—temperature is set manually via the PID controller; multi-step thermal programming requires external PLC integration via RS-485.
Is refrigeration capacity validated below 10 °C?
Yes—performance down to 4 °C is certified per manufacturer test reports using calibrated glycol baths and traceable thermistors.
Can the shaker operate continuously for >100 hours?
Yes—rated for unattended 24/7 operation; the 500-hour timer serves as a fail-safe endpoint, not a duty-cycle limit.
What documentation is supplied for IQ/OQ validation?
Factory calibration certificates (temperature, speed), electrical safety reports (IEC 61010), and dimensional drawings are provided; site-specific OQ protocols must be developed per user SOPs.
