Zhicheng ZWYR-211D Horizontal Foot-Operated Door Benchtop Incubator Shaker with 4.3″ True-Color Touchscreen

Overview

The Zhicheng ZWYR-211D is a horizontally configured, foot-actuated door incubator shaker engineered for high-precision, long-duration orbital cultivation under tightly controlled thermal and mechanical conditions. It operates on the principle of forced-air convection combined with precise PID-regulated orbital motion (30–300 rpm, Φ26 mm orbit), enabling reproducible suspension culture of microbial, mammalian, and hybridoma cell lines across temperature ranges from 4 °C to 60 °C. Designed for GxP-aligned laboratories, its architecture integrates dual-loop thermal control—primary PID feedback from multiple internal sensors plus an independent mechanical overtemperature limiter—to meet fundamental safety requirements outlined in ISO 13485 Annex A and IEC 61010-1 for laboratory equipment. The unit’s 304 L chamber volume and large 940 × 584 mm stainless-steel platform support multi-vessel configurations (e.g., stacked flasks, deep-well plates, or bioreactor bags), making it suitable for scale-up workflows in upstream bioprocessing and QC microbiology.

Key Features

• 4.3-inch capacitive touchscreen HMI with 480×272 resolution and 65K-color rendering, supporting intuitive graphical navigation, real-time trend visualization, and animated status feedback
• 9-segment, 18-step programmable protocol engine with ramp-and-hold capability; each segment supports independent temperature setpoint, speed, duration (0–999.9 min), and logic flags (e.g., refrigeration enable, door lock override)
• Foot-operated pneumatic-assisted door mechanism—designed to minimize manual contact during aseptic operations and reduce ergonomic strain during high-frequency access
• Dual-stage cooling system using R134a refrigerant with adaptive load compensation and frost-free evaporator management for uninterrupted low-temperature operation down to 4 °C
• Triple-layer safety architecture: (1) personnel protection via Class I insulation, earth-leakage circuit breaker (ELCB), and ±2 °C or >±5 rpm; (3) asset protection via independent mechanical overtemperature cutout (non-PID) and compressor thermal overload relay
• RS-232 interface compliant with ASTM E1382-95 data logging standards; embedded thermal printer supports GLP-compliant timestamped output of setpoints, actuals, alarms, and event logs

Sample Compatibility & Compliance

The ZWYR-211D accommodates standard labware including Erlenmeyer flasks (up to 5 L), roller bottles, microtiter plates (with adapter), and custom bioreactor vessels secured via universal clamping rails. Its uniform airflow distribution (validated per ISO 15197:2013 Annex D methodology) ensures ≤±1 °C spatial temperature deviation at 37 °C across the full shelf surface. The unit conforms to electromagnetic compatibility requirements per EN 61326-1:2013 and carries CE marking under the Low Voltage Directive 2014/35/EU and EMC Directive 2014/30/EU. While not FDA 510(k)-cleared, its firmware architecture supports audit-trail generation and parameter encryption—features aligned with ALCOA+ principles for data integrity under 21 CFR Part 11 when integrated with validated third-party LIMS or ELN systems.

Software & Data Management

No proprietary PC software is bundled; all configuration, monitoring, and reporting occur locally via the embedded HMI. The RS-232 port transmits ASCII-formatted telemetry (timestamp, setpoint, PV, rpm, alarm status) at user-defined intervals (1–60 s), compatible with industry-standard SCADA platforms (e.g., Ignition, WinCC) and CSV ingestion into Python/Pandas or MATLAB for kinetic modeling. Thermal printouts include device ID, operator ID (if entered), start/stop timestamps, and checksum-verified parameter snapshots—enabling traceability per ISO/IEC 17025:2017 clause 7.7. Firmware updates are performed via USB flash drive with SHA-256 signature verification to prevent unauthorized modification.

Applications

This shaker serves core functions in regulated and research-intensive environments: aerobic bacterial culture (E. coli, Bacillus spp.) under controlled O₂ transfer conditions; yeast fermentation kinetics studies requiring sub-ambient temperature modulation; hybridoma expansion for monoclonal antibody production; enzymatic assay development where thermal drift must remain <0.1 °C/h; and environmental microbiology testing (e.g., ISO 6222:2021 water coliform enumeration). Its wide operating range also supports plant tissue culture (22–28 °C), psychrophilic organism propagation (4–12 °C), and accelerated stability protocols per ICH Q1A(R2).

FAQ

Does the ZWYR-211D support network connectivity (Ethernet/Wi-Fi)?
No—only isolated RS-232 serial communication is provided to maintain electromagnetic isolation and simplify validation in regulated labs.
Can the built-in printer generate PDF reports?
No—the thermal printer produces continuous-feed paper logs only; digital export requires external serial capture.
Is the refrigeration system serviceable in-field?
Yes—R134a service ports and modular compressor assembly allow certified technicians to perform leak testing, recharge, and replacement without chamber disassembly.
What calibration certificates are supplied?
A factory-issued temperature and speed calibration report (traceable to NIM, China) is included; users must perform periodic in-house verification per their SOPs using accredited reference probes.
How is door-open safety enforced?
Mechanical microswitches interrupt motor power and disable heating/cooling circuits within 5 mm—complying with EN 61010-1 Clause 10.3.2.
