Zhicheng ZWYR-D2402 Dual-Stackable Incubator Shaker with True-Color Touchscreen

Overview

The Zhicheng ZWYR-D2402 is a dual-stackable, microprocessor-controlled orbital incubator shaker engineered for high-density laboratory environments where spatial efficiency, thermal stability, and mechanical reproducibility are critical. It operates on the principle of controlled orbital motion—generating uniform circular agitation (Ø0–50 mm amplitude) to suspend and homogenize biological samples under precisely regulated temperature conditions (4–60 °C). Its dual-platform architecture enables independent or synchronized operation of two horizontally aligned shaking decks within a single footprint—effectively doubling usable incubation-shaking capacity without expanding floor space. The system integrates forced-air convection with P.I.D. feedback control, achieving ±0.5 °C temperature fluctuation (at 37 °C) and ±1 °C uniformity across each chamber. Designed for long-duration, unattended operation in GLP-compliant workflows, it supports continuous monitoring and programmable multi-step protocols essential for cell culture expansion, microbial fermentation, hybridization kinetics, and enzymatic assays.

Key Features

• 5.6-inch true-color TFT touchscreen (640 × 480 resolution, 65K color depth) with intuitive graphical interface for real-time parameter visualization and touch-based navigation.
• Dual independent shaking platforms (800 × 430 mm each), supporting up to 192 L total chamber volume per deck; fully stackable configuration allows vertical integration of up to three units (not included).
• Continuous amplitude adjustment from Ø0 to 50 mm via precision cam-driven mechanism—enabling optimization for viscous media, fragile suspension cultures, or high-density bioreactor inocula.
• Triple-layer safety architecture: (1) Personnel protection via isolated earth-leakage circuit breaker and overcurrent disconnection; (2) Sample integrity assurance through redundant emergency shutdown triggered by speed/temperature deviation; (3) Equipment safeguarding via independent over-temperature cut-off, refrigerant pressure monitoring, and frost-free dual-circuit cooling (R134a).
• 9-segment/18-step programmable protocol engine supporting ramp-hold profiles, temperature gradients, oscillation frequency sweeps, and timed start/stop sequences—each step configurable up to 999.9 minutes.
• Embedded thermal printer (miniature, direct-feed) and RS-232 serial interface for audit-ready data logging; optional integration with LIMS via ASCII command protocol.

Sample Compatibility & Compliance

The ZWYR-D2402 accommodates standard microbiological vessels—including Erlenmeyer flasks (up to 5 L), baffled bottles, deep-well plates, and custom bioreactor sleeves—secured via universal clamping trays or silicone matting. Its stainless-steel 304 interior (rounded corners, electropolished finish) ensures corrosion resistance against acidic/basic reagents and facilitates ISO 14644-1 Class 5 cleanroom-compatible decontamination. The unit complies with IEC 61010-1 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and meets electromagnetic compatibility (EMC) requirements per EN 61326-1. While not certified for ISO/IEC 17025 calibration traceability out-of-box, its temperature and speed sensors support external verification per ASTM E2252 (Standard Practice for Calibration of Laboratory Thermometers) and ISO 20957-3 (Fitness Equipment — Testing Methods).

Software & Data Management

All operational parameters—including setpoints, actual readings, alarm events, and runtime logs—are timestamped and stored internally (non-volatile memory, 10,000-entry capacity). The embedded RS-232 interface permits bidirectional communication using ASCII-based command syntax, enabling remote configuration, real-time data streaming, and automated report generation via third-party SCADA or ELN platforms. Audit trail functionality records user ID (via password-protected access levels), parameter changes, and safety interventions—supporting FDA 21 CFR Part 11 readiness when paired with validated electronic signature software. Temperature calibration offsets can be applied per chamber (±5.0 °C range, 0.1 °C resolution) to correct for sensor drift or vessel-specific thermal lag.

Applications

• Molecular biology: Plasmid amplification, PCR master mix equilibration, DNA/RNA hybridization, and restriction enzyme digestion under controlled thermal-agitation conditions.
• Cell culture: Suspension-adapted mammalian cell line propagation, insect cell expression systems (e.g., Sf9), and yeast fermentation (S. cerevisiae, P. pastoris) requiring precise O₂ transfer modulation.
• Pharmaceutical development: Stability testing of protein therapeutics under agitated thermal stress (ICH Q5C), excipient solubility screening, and dissolution kinetics modeling.
• Environmental microbiology: BOD incubation, activated sludge respirometry, and biodegradation rate studies with simultaneous aeration and temperature ramping.
• Food safety analytics: Pathogen enrichment (e.g., Salmonella, Listeria) in buffered peptone water, followed by immunomagnetic separation preparation.

FAQ

What is the maximum flask size supported per platform?
Each 800 × 430 mm platform accommodates standard 5 L Erlenmeyer flasks with side-arm orientation; load distribution must remain within 20 kg per deck to maintain mechanical stability at 300 rpm.
Does the unit support CO₂ or humidity control natively?
No—CO₂ and humidity modules are optional add-ons requiring factory installation and separate calibration; base configuration includes only temperature and orbital motion control.
Can the two decks operate at different temperatures and speeds simultaneously?
Yes—the ZWYR-D2402 features independent PID controllers and motor drivers for each chamber, allowing asynchronous programming of temperature, rpm, amplitude, and timing profiles.
Is firmware upgrade capability available?
Firmware updates are performed via RS-232 connection using Zhicheng-provided utility software; version history and release notes are accessible through authorized service partners.
What maintenance intervals are recommended for long-term reliability?
Biannual inspection of drive belt tension, fan filter cleaning, refrigerant pressure verification, and calibration validation against NIST-traceable references is advised per ISO/IEC 17025 Annex A.3 guidelines.
