Zhicheng ZWYR-2112B Dual-Layer Full-Color Touchscreen Incubator Shaker

Overview

The Zhicheng ZWYR-2112B Dual-Layer Full-Color Touchscreen Incubator Shaker is an engineered platform for precise, reproducible, and programmable temperature-controlled orbital shaking in life science laboratories. It operates on the principle of forced-air convection combined with high-fidelity PID-regulated thermal control and digitally stabilized motor-driven oscillation. Designed for applications requiring strict adherence to incubation parameters—such as microbial culture expansion, protein expression optimization, enzymatic assays, and cell-based assay development—the ZWYR-2112B integrates dual independent shaking decks within a single large-volume chamber (582 L), enabling parallel processing of heterogeneous samples under identical environmental conditions. Its architecture supports GxP-aligned workflows through deterministic control logic, audit-ready parameter logging, and fail-safe hardware redundancies.

Key Features

• Dual-layer stainless-steel shaking platforms (970 × 560 mm each), supporting simultaneous multi-vessel experiments with uniform thermal and mechanical coupling.
• 5.6-inch 65K-color resistive touchscreen HMI with 640 × 480 resolution, delivering intuitive graphical navigation, real-time animated status visualization, and bilingual (English/Chinese) interface support—configured at factory default for international deployment.
• Advanced 9-segment × 18-step programmable protocol engine: each segment allows independent ramp rate (°C/min) and hold duration (0–999.9 min), enabling complex temperature-gradient incubations (e.g., cold shock → induction → harvest) and kinetic oscillation profiling.
• Triple-tier safety architecture: (1) Personnel protection via Class I grounded enclosure, leakage current detection (±2 °C or >±5 rpm from setpoint; (3) Equipment safeguarding via independent mechanical overtemperature cutoff (105 °C threshold), compressor overload sensing, and frost-free refrigeration management.
• R134a-based air-cooled refrigeration system with power-modulated compressor control—capable of sub-ambient operation down to 4 °C with <0.5 °C thermal drift across full load, verified per ISO 17025 calibration traceability protocols.
• Embedded thermal printer and RS-232 serial interface compliant with ASTM E2500-13 data capture requirements; supports timestamped printout of setpoints, actual values, alarms, and protocol execution logs.

Sample Compatibility & Compliance

The ZWYR-2112B accommodates standard laboratory vessels—including Erlenmeyer flasks (up to 5 L), Fernbach flasks, deep-well plates, and custom bioreactor sleeves—across both decks without mechanical interference. Its Φ35 mm orbital motion (30–300 rpm, ±1 rpm accuracy) ensures laminar fluid mixing suitable for aerobic microbial cultures, suspension-adapted mammalian cells, and viscous fermentation broths. The chamber’s interior (1106 × 625 × 850 mm, 304 stainless steel) meets ISO 14644-1 Class 7 cleanroom compatibility standards when operated under positive-pressure HEPA-filtered airflow (optional accessory). Regulatory alignment includes design conformity to IEC 61010-1:2010 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and electromagnetic compatibility per EN 61326-1:2013. For GLP/GMP environments, the device supports 21 CFR Part 11-compliant electronic record retention when paired with validated third-party LIMS integration software.

Software & Data Management

No proprietary PC software is required for basic operation; all configuration, monitoring, and reporting occur natively via the onboard HMI. However, the RS-232 interface enables bidirectional communication with external SCADA systems or laboratory informatics platforms using ASCII-based command protocols (e.g., “GET_TEMP”, “SET_RPM=180”). Timestamped thermal and rotational data are stored in non-volatile memory for ≥30 days (circular buffer) and exported in CSV format via printer or serial dump. Parameter encryption (AES-128) prevents unauthorized modification of critical settings—essential for multi-user core facilities. All alarm events—including door-open interruptions, temperature excursions, and power-loss recovery—are logged with ISO 8601 timestamps and severity codes (Level 1–3), facilitating root-cause analysis during internal audits.

Applications

• High-density bacterial culture (E. coli, Bacillus spp.) under controlled oxygen transfer rates and temperature gradients.
• Recombinant protein expression in autoinduction media, where phased thermal shifts optimize soluble yield.
• Enzyme kinetics studies requiring precise co-incubation of substrate/enzyme mixtures at defined agitation intensities.
• Mammalian cell line adaptation in serum-free suspension media, leveraging dual-deck capability for comparative passage experiments.
• Environmental microbiology assays—e.g., biodegradation rate testing of xenobiotics under regulated temperature-cycling regimes.
• Pharmaceutical stability testing per ICH Q1A(R2), including accelerated degradation studies at elevated temperatures with continuous agitation.

FAQ

Does the ZWYR-2112B support remote monitoring via Ethernet or Wi-Fi?
No—network connectivity is not integrated. Remote access requires external serial-to-Ethernet converters compatible with Modbus RTU or custom ASCII bridging firmware.

Can the two shaking decks operate at different temperatures or speeds?
No—the system maintains a single homogeneous chamber environment; both decks share identical temperature and oscillation parameters.

Is the refrigeration system serviceable in-field by authorized technicians?
Yes—R134a charging ports, compressor diagnostics pins, and evaporator coil access panels are standardized per AHRI 700 guidelines and documented in the service manual (available under NDA).

What calibration documentation is provided with shipment?
Each unit ships with a factory-issued calibration certificate traceable to NIM (National Institute of Metrology, China), covering temperature uniformity (9-point grid), speed accuracy (laser tachometer verification), and refrigeration performance (cool-down time from 25 °C to 4 °C).

How is power-loss recovery implemented?
Upon AC restoration, the device resumes the last active program step with original setpoints, provided the outage duration was <120 seconds; longer outages trigger a safe cooldown sequence before restart authorization.
