Zhicheng ZWYR-200D Desktop High-Speed Incubated Orbital Shaker with 4.3″ Full-Color Touchscreen

Overview

The Zhicheng ZWYR-200D is a high-performance desktop incubated orbital shaker engineered for precision-controlled microbial cultivation, enzymatic assays, hybridization reactions, and cell-based studies requiring simultaneous regulation of temperature and oscillatory motion. It operates on the principle of orbital shaking—generating uniform circular motion via a track-driven platform—to ensure homogeneous suspension of cultures while minimizing shear stress on sensitive biological samples. Unlike basic shakers, the ZWYR-200D integrates active refrigeration (R134a-based, frost-free air cooling) and PID-controlled heating within a thermally insulated chamber, enabling stable operation from 4 °C to 60 °C—critical for low-temperature fermentation or high-yield protein expression workflows. Its sealed, forced-air convection system ensures rapid thermal equilibration and exceptional uniformity (≤±1 °C at 37 °C), meeting stringent requirements for reproducible bioprocess development and QC testing in regulated environments.

Key Features

• 4.3-inch full-color capacitive touchscreen (480 × 272 pixels, 65K colors) with intuitive graphical interface supporting animated status feedback and multilingual navigation (English default)
• PID microprocessor with environmental scanning algorithm for adaptive thermal and rotational control—reducing overshoot and improving long-term stability
• Advanced 9-segment × 18-step programmable logic: each segment supports independent ramp rate (°C/min) and hold duration (0–999.9 min), enabling complex temperature-gradient incubations (e.g., cold shock → induction → harvest)
• Dual-mode operation: fixed-parameter mode for routine runs; full-program mode for multi-stage protocols including speed ramps, temperature staircases, and conditional triggers
• Triple-layer safety architecture: (1) personnel protection via Class I insulation, earth-leakage circuit breaker (ELCB), and real-time current monitoring; (2) sample integrity safeguards including redundant temperature cutoffs (electronic + mechanical), automatic shutdown on lid opening or speed deviation >±5 rpm; (3) equipment/fire protection via independent overheat limiter on heating elements
• Built-in thermal printer and RS-232 serial interface for traceable data export—supports CSV-formatted logs with timestamps, setpoints, actual values, and alarm events

Sample Compatibility & Compliance

The ZWYR-200D accommodates standard labware including Erlenmeyer flasks (up to 2 L), culture tubes, deep-well plates, and custom trays mounted on its single 400 × 370 mm stainless-steel platform (Φ0–50 mm orbit diameter, infinitely adjustable). Its 69 L internal volume and optimized airflow path minimize condensation and cross-contamination risks during extended runs. The unit is constructed with medical-grade stainless steel interior and flame-retardant ABS housing, compliant with IEC 61010-1:2010 for laboratory electrical safety. While not CE-marked for EU distribution without local conformity assessment, its design aligns with core principles of ISO 13485 (for in vitro diagnostic support), USP (analytical instrument qualification), and FDA 21 CFR Part 11 when used with validated data management practices—including electronic signature enforcement, audit trail generation, and parameter lockout functions.

Software & Data Management

No proprietary PC software is bundled; however, the RS-232 interface enables integration with third-party laboratory information management systems (LIMS) or custom Python/Node-RED scripts using standard ASCII command protocol (e.g., “GET TEMP”, “SET RPM=350”). All operational parameters—including programs, calibration offsets, user access levels, and clock settings—are retained in non-volatile memory during power loss. The embedded printer outputs time-stamped records of start/stop events, temperature and speed profiles, and triggered alarms—essential for GLP documentation. Optional firmware updates (delivered via USB stick) maintain compatibility with evolving regulatory expectations around data integrity and cybersecurity (per NIST SP 800-53 Rev. 5 controls for lab instruments).

Applications

This shaker serves as a foundational platform in academic research labs studying bacterial growth kinetics under variable thermal regimes, industrial biotech facilities optimizing recombinant protein titers in shake-flask bioreactors, and clinical microbiology units performing AST (antibiotic susceptibility testing) with precise incubation timing. Its sub-ambient capability supports psychrophilic organism studies, while the wide speed range (30–600 rpm) accommodates both viscous media (e.g., Pichia pastoris methanol-fed batches) and low-density suspensions (e.g., mammalian cell transfection mixes). Regulatory users leverage its programmability for USP / microbial enumeration validations and ISO 21528-1 food pathogen enrichment protocols—where defined temperature ramps and dwell times are mandatory.

FAQ

Does the ZWYR-200D support remote monitoring or Ethernet connectivity?
No—only RS-232 serial communication is provided. Network-enabled variants require external hardware gateways.
Can multiple temperature zones be controlled independently within the chamber?
No—the unit maintains a single uniform temperature field across the entire 69 L workspace.
Is validation documentation (IQ/OQ/PQ protocols) available from the manufacturer?
Zhicheng provides basic factory test reports; site-specific IQ/OQ must be performed by qualified lab personnel per ISO/IEC 17025 guidelines.
What is the expected service life of the R134a refrigeration system under continuous 24/7 operation?
Rated for ≥20,000 hours of compressor runtime with annual preventive maintenance (filter drying, refrigerant pressure verification).
Are calibration certificates traceable to NIST or other national standards bodies included?
Certificates are issued upon request at additional cost; base configuration includes internal sensor self-test logs only.
