DRETOP ZRQ-150 Artificial Climate Incubator

Overview

The DRETOP ZRQ-150 Artificial Climate Incubator is a precision-engineered environmental simulation system designed for reproducible, long-term biological experimentation under tightly controlled temperature, humidity, and photoperiod conditions. It operates on a dual-mode thermal management principle—combining P.I.D.-regulated resistive heating with a hermetically sealed, CFC-free vapor-compression refrigeration cycle—to maintain stable setpoints across dynamic lighting states. Unlike standard incubators, the ZRQ-150 integrates full-spectrum LED illumination with programmable spectral composition (red, blue, green, white, violet), enabling wavelength-specific physiological studies in plant physiology, photomorphogenesis, and circadian rhythm research. Its chamber architecture supports ISO 14644-1 Class 8 cleanroom-compatible operation when used with appropriate sterilization protocols, making it suitable for GLP-compliant seed germination assays, microbial culture stability testing, BOD incubation per ASTM D5210, and small-animal acclimation studies.

Key Features

• Triple-side full-spectrum LED illumination system with 6-level intensity adjustment (0–12,000 lx), supporting red:blue ratios from 4:1 to 9:1 for optimized phytochrome and cryptochrome activation
• Microprocessor-based P.I.D. climate control with independent regulation of temperature (±0.1 °C resolution), humidity (30–95% RH), and light timing—synchronized to simulate diurnal cycles or extended photoperiods
• 30-segment programmable controller enabling multi-step environmental profiles (e.g., ramp-hold-cool cycles), with automatic transition between day/night modes based on light sensor input
• Stainless steel interior chamber (304 grade) with removable, height-adjustable shelves; double-glazed tempered glass inner door and magnetic nano-seal outer door for thermal integrity and visual monitoring without disturbance
• Eco-optimized refrigeration: high-efficiency rotary compressor, auto-defrost evaporator, and cross-flow air circulation system ensuring ±0.5 °C temperature uniformity and ±0.5% RH humidity uniformity throughout the 150 L working volume
• Robust safety architecture including over-temperature/over-humidity alarms, power-fail data retention, compressor delay protection, and manual/auto defrost selection

Sample Compatibility & Compliance

The ZRQ-150 accommodates a broad range of biological specimens—from Petri dishes, multi-well plates, and tissue culture flasks to small vertebrate models (e.g., zebrafish larvae, Drosophila vials, rodent pups) and potted seedlings up to 30 cm tall. Its non-UV-emitting LED array eliminates phototoxic stress during prolonged exposure, satisfying ICH Q5C guidelines for biopharmaceutical stability testing under light. The unit complies with IEC 61000-4 electromagnetic compatibility standards and meets structural safety requirements per GB/T 14710 (Chinese national standard equivalent to IEC 61010-1). While not certified for FDA 21 CFR Part 11 out-of-the-box, its data logging interface supports third-party audit-trail integration for GxP environments when paired with validated software.

Software & Data Management

The ZRQ-150 features an embedded LCD interface with real-time parameter display and local event logging (up to 10,000 entries), including timestamped deviations, alarm triggers, and operational mode transitions. Optional RS-485 Modbus RTU output enables connection to SCADA systems or centralized lab monitoring platforms (e.g., LabArchives, DeltaV). For advanced protocol development, the incubator supports CSV export of logged data via USB port—compatible with Python/Pandas analysis pipelines and MATLAB-based growth curve modeling. All firmware updates are delivered via secure offline package to preserve network isolation in regulated laboratories.

Applications

• Plant science: Controlled-environment phenotyping, seed germination kinetics (ISTA-certified protocols), tissue culture acclimatization, and LED spectral optimization trials for vertical farming R&D
• Microbiology: BOD₅ determination per APHA Standard Methods 5210B, fungal sporulation studies, and antibiotic susceptibility testing under variable humidity regimes
• Entomology & developmental biology: Diapause induction in lepidopteran species, embryonic staging in Drosophila, and metamorphosis synchronization in aquatic invertebrates
• Environmental toxicology: OECD 202 and 211 compliant algal growth inhibition assays requiring precise light:temperature coupling
• Biomedical research: Hypoxia-reoxygenation preconditioning of primary cells, stem cell differentiation under circadian-mimetic lighting, and microbiome culture stability assessment

FAQ

Does the ZRQ-150 support remote monitoring via Ethernet or Wi-Fi?
No—network connectivity is intentionally omitted to ensure electromagnetic isolation and regulatory compliance in GMP labs; data transfer occurs exclusively via USB or RS-485.
Can the LED spectrum be customized beyond RGBWV configurations?
Yes—DRETOP offers OEM spectral tuning using SMD aluminum-core PCBs with narrow-band LEDs (e.g., 660 nm ±5 nm red, 450 nm ±5 nm blue); lead time applies for custom optical designs.
Is the unit suitable for continuous 24/7 operation at 4 °C with 95% RH?
Yes—the compressor cooling system and condensate management design enable uninterrupted operation across the full specified range, validated for ≥6-month mean time between failures (MTBF) under load.
What calibration documentation is provided with shipment?
Each unit ships with a factory calibration certificate traceable to NIM (National Institute of Metrology, China), covering temperature (at three points), humidity (at two RH levels), and illuminance (at center and corners of chamber).
Are spare parts such as LED modules and humidity sensors available separately?
Yes—DRETOP maintains a 5-year spare parts inventory for all ZRQ-series components, including field-replaceable LED light bars, capacitive RH sensors, and PTC heating elements.
