CZGY GYGZ-2FHS Dual-Shelf Illuminated Temperature- and Humidity-Controlled Shaking Incubator

Overview

The CZGY GYGZ-2FHS Dual-Shelf Illuminated Temperature- and Humidity-Controlled Shaking Incubator is a precision-engineered platform for simultaneous environmental control and orbital agitation of biological samples. It integrates three critical environmental parameters—temperature, relative humidity, and photoperiodic illumination—within a dual-tier shaking chamber, enabling reproducible simulation of physiological or ecological growth conditions. The instrument operates on the principle of forced-air convection for uniform thermal distribution and employs a brushless DC motor to deliver stable, low-vibration orbital motion (26 mm orbit diameter) across a wide speed range (30–300 rpm). Its microprocessor-based control system utilizes advanced fuzzy PID algorithms to maintain temperature stability within ±0.5 °C and humidity within ±5 %RH—parameters essential for sensitive applications such as microbial fermentation kinetics, plant tissue culture under diurnal cycles, and light-dependent enzyme expression studies.

Key Features

• Dual independent stainless-steel shaking platforms (490 × 490 mm each), configured in stacked arrangement for high-density sample processing without cross-tier interference.
• Triple-face (left, right, front) LED-based illumination system delivering ≥12,000 lx intensity; supports 6-level manual adjustment and 30-segment programmable light/dark scheduling to emulate natural photoperiods.
• Brushless DC motor drive ensures maintenance-free operation, consistent torque delivery at all speeds, and long-term rotational stability with ±1 rpm accuracy—critical for kinetic assays requiring precise shear input.
• High-efficiency refrigeration-compression system (360 W) coupled with 1200 W PTC heating enables rapid thermal response and stable setpoint maintenance across the full 4–60 °C operating range.
• Segmented LCD interface with intuitive menu navigation displays real-time values for temperature, humidity, speed, illumination level, and timer; supports password-protected parameter locking for GLP-compliant workflows.
• Insulated double-wall construction with stainless-steel interior and seamless welding minimizes thermal bridging and condensation risk, enhancing long-term reliability in high-humidity environments.

Sample Compatibility & Compliance

The GYGZ-2FHS accommodates standard microbiological and cell culture vessels—including Erlenmeyer flasks (up to 5 L), test tubes, Petri dishes, and multi-well plates—via its universal stainless-steel spring clamps. Its humidity control (50–90 %RH) supports hygroscopic cultures such as filamentous fungi and mosses, while the illuminated chamber meets ASTM D4329 (plastic exposure testing) and ISO 8513 (photobiological safety classification) foundational requirements for light-controlled incubation. Though not certified for IEC 61000-6-3 EMC or UL 61010-1 out-of-box, the unit conforms to general laboratory equipment safety expectations per GB 4793.1 (China’s equivalent to IEC 61010-1) and includes over-temperature, over-humidity, and motor stall protection circuits.

Software & Data Management

The onboard controller logs time-stamped operational data—including setpoints, actual readings, alarm events, and runtime hours—for up to 30 days. While no proprietary PC software is bundled, data export is supported via RS-232 serial interface (optional USB-to-serial adapter) for integration into third-party LIMS or ELN systems. All parameter changes are timestamped and retain audit trail metadata, satisfying basic FDA 21 CFR Part 11 requirements for electronic records when used with validated external software. Firmware updates are performed via USB flash drive, ensuring traceability and version control.

Applications

• Photoperiod-regulated plant seedling development and circadian rhythm studies under controlled RH and temperature gradients.
• Aerobic microbial cultivation for bioprocess optimization, including recombinant protein expression in E. coli and Pichia pastoris under variable light intensities.
• Environmental microbiology assays involving soil slurry enrichment or wastewater biofilm formation under simulated diurnal illumination.
• Enzyme activity profiling where light activation (e.g., photolyases) or inhibition (e.g., light-sensitive oxidoreductases) must be decoupled from thermal effects.
• Stability testing of probiotic formulations and fermented dairy products under combined thermal, humid, and photic stress conditions.

FAQ

What is the maximum flask capacity supported per shelf?
Each 490 × 490 mm shelf accommodates up to four 2 L Erlenmeyer flasks or eight 1 L flasks using the included universal spring clamps.
Is remote monitoring or Ethernet connectivity available?
No native Ethernet or Wi-Fi interface is integrated; however, RS-232 output enables connection to industrial PLCs or custom SCADA nodes via serial-to-Ethernet gateways.
Can the humidity system operate independently of temperature control?
Yes—the humidity module functions across the full 4–60 °C temperature range and can be activated or deactivated regardless of active heating or cooling mode.
Does the instrument comply with ISO/IEC 17025 calibration requirements?
The unit includes factory calibration certificates for temperature and speed sensors; users must perform periodic verification using NIST-traceable reference standards per their internal quality procedures.
Are custom shelving configurations or CO₂ supplementation options available?
CZGY offers OEM customization—including single-shelf variants, extended height enclosures, and CO₂ inlet ports—but these require minimum order quantities and separate validation documentation.
