Zhicheng ZWYR-200D Multi-Amplitude Orbital Shaker with Touchscreen Color LCD

Overview

The Zhicheng ZWYR-200D Multi-Amplitude Orbital Shaker with Touchscreen Color LCD is a precision-engineered laboratory instrument designed for controlled, reproducible orbital agitation under regulated temperature conditions. It operates on the principle of eccentric track-driven orbital motion—generating uniform, low-shear circular oscillation ideal for suspension cultures, microbial growth, enzyme kinetics, and hybridization protocols. Unlike basic shakers, the ZWYR-200D integrates active thermal regulation (4–60 °C) with forced-air convection, enabling simultaneous control of temperature and agitation parameters across extended durations. Its microprocessor-based PID control architecture continuously monitors chamber temperature and motor feedback to maintain stability within ±0.1 °C at 37 °C—a critical performance benchmark for mammalian cell culture and diagnostic assay development. The system’s robust stainless-steel interior, reinforced aluminum alloy frame, and vibration-dampened base ensure mechanical integrity during high-speed operation (up to 600 rpm), minimizing cross-contamination risk and preserving sample integrity in GxP-aligned environments.

Key Features

• 7-inch true-color TFT LCD touchscreen interface with intuitive graphical navigation, supporting multilingual UI overlays (English default) and real-time animated status visualization
• 9-stage, 18-step programmable sequence logic: each stage comprises independently configurable ramp (linear temperature/speed gradient) and hold segments, with time resolution down to 0.1 minute and up to 99 repeat cycles per program
• Continuously variable orbit diameter (Φ0–50 mm), allowing precise shear modulation for sensitive applications such as stem cell expansion or fragile protein complex assembly
• Dual-mode thermal control: selectable heating-only or full heating/cooling operation, optimized for ambient conditions between 5–25 °C
• RS-232 serial interface compliant with standard SCPI command sets, enabling integration into LIMS and automated lab workflows via ASCII protocol
• Embedded thermal printer (optional) provides timestamped audit trails for GLP/GMP documentation—supporting traceability requirements per FDA 21 CFR Part 11 when paired with validated software
• Six user-configurable operational modes: constant vs. programmed setpoint control; heating-only vs. thermoregulated cooling; power-failure auto-resume; door interlock activation; print output enable/disable; and silent mode for noise-sensitive facilities

Sample Compatibility & Compliance

The ZWYR-200D accommodates diverse vessel formats—including Erlenmeyer flasks (50–1000 mL), test tubes, deep-well plates, and custom bioreactor sleeves—via its 400 × 370 mm platform with non-slip silicone matting. Its 69 L chamber volume and uniform airflow design meet ISO 13408-1 (aseptic processing) spatial homogeneity criteria when operated within specified ambient limits. Temperature uniformity (≤±1.0 °C at 37 °C) and stability (≤±0.1 °C) are verified per ASTM E145-22 Annex A3 for laboratory ovens and incubators, ensuring compliance with USP for cell culture equipment qualification. The unit conforms to IEC 61010-1:2010 safety standards for electrical equipment used in laboratory settings and carries CE marking under the EU Low Voltage Directive.

Software & Data Management

While the ZWYR-200D operates autonomously via onboard firmware, its RS-232 port supports bidirectional communication with third-party data acquisition platforms (e.g., LabVIEW, MATLAB, or custom Python scripts using pySerial). All program parameters—including target temperature, speed profile, orbit setting, and timer values—are stored in non-volatile memory with write-cycle protection. Timestamped event logs (start/stop, alarm triggers, parameter changes) can be exported in CSV format for regulatory review. When used with validated external software, the system supports electronic signature capture, audit trail generation, and role-based access control—key prerequisites for FDA 21 CFR Part 11 compliance in pharmaceutical QC labs.

Applications

• Bacterial and yeast fermentation studies requiring precise oxygen transfer modulation via orbit adjustment
• Mammalian and insect cell suspension culture under tightly controlled thermal-agitation profiles
• Nucleic acid hybridization (e.g., Southern/Northern blotting), where consistent mixing prevents probe precipitation
• Enzymatic reaction kinetics assays demanding thermal stability across multi-hour time courses
• Antibiotic susceptibility testing (AST) using broth microdilution methods per CLSI M07-A11 guidelines
• Protein solubilization and refolding protocols sensitive to shear-induced aggregation
• Environmental microbiology sampling preparation, including waterborne pathogen enrichment per ISO 9308-1

FAQ

Does the ZWYR-200D support remote monitoring via Ethernet or Wi-Fi?
No—the device features only an RS-232 serial interface. Network connectivity requires an external RS-232-to-Ethernet converter with appropriate driver support.
Can multiple platforms be installed for parallel processing?
No—this model is configured with a single fixed platform. For multi-tier configurations, consider the ZWYR-300 series or custom OEM integration.
Is calibration certification included with shipment?
A factory-issued temperature and speed verification report is provided. Full IQ/OQ documentation and on-site calibration services are available as optional add-ons.
What refrigerant is used in the cooling system?
The unit employs R134a refrigerant, compliant with current EU F-Gas Regulation (EU) No 517/2014 and EPA SNAP program requirements.
How is door interlock functionality implemented?
A mechanical switch interrupts power to the drive motor and heater upon door opening, resuming operation only after confirmation via touchscreen prompt—preventing uncontrolled thermal drift or mechanical hazard.
