DRETOP ZSH.CP-500 Multi-Function CO₂ Incubator

Overview

The DRETOP ZSH.CP-500 Multi-Function CO₂ Incubator is an air-jacketed, microprocessor-controlled environmental chamber engineered for precision cell culture under controlled CO₂, temperature, and optional illumination conditions. Designed to meet the operational demands of academic research laboratories, biopharmaceutical QC units, and clinical cell therapy facilities, it integrates core CO₂ incubation functionality with configurable modular capabilities—including photobiological stimulation (via tunable LED arrays) and programmable diurnal cycling—without compromising thermal or gas stability. Its measurement architecture relies on a dual-path infrared (IR) CO₂ sensor, which delivers drift-free, humidity- and temperature-insensitive concentration monitoring essential for high-fidelity long-term experiments. The chamber employs a fully independent heating system based on nickel-chromium alloy heaters, coupled with a high-efficiency refrigeration module featuring optimized evaporator-condenser geometry and compressor protection logic (including start-delay and off-cycle intervals). Structural integrity is ensured by a seamless mirror-finish stainless-steel interior with radius-corner transitions, minimizing microbial harborage points while supporting ISO 14644-compliant cleaning protocols.

Key Features

• Air-jacketed thermal design with ceramic fiber insulation for superior heat retention and low energy consumption (1450 W nominal input)
• Infrared CO₂ sensor with <3-minute recovery to 5% setpoint after 30-second door opening—critical for multi-user lab environments
• Microcomputer-based P.I.D. temperature controller offering ±0.5 °C stability and 0.1 °C resolution across 0–65 °C range
• UV-C germicidal lamp (ozone-free) integrated into ceiling assembly for periodic sterilization of recirculated air and humidification reservoir vapor
• HEPA-grade inlet air filtration (99.998% efficiency at ≥0.3 µm) preventing particulate ingress during ambient air exchange
• Double-door configuration with tempered glass inner door and magnetic nano-composite gasket ensuring minimal thermal leakage and condensation-free viewing
• Modular illumination system supporting red/blue LED spectral bands (optional), enabling photomodulation studies without radiant heating artifacts
• Programmable multi-segment controller (99 cycles × 30 segments/cycle, up to 9999 minutes per segment) for simulating circadian or stress-response profiles
• Self-diagnostic firmware with automatic defrosting (non-energy-intensive), compressor runtime monitoring, and parameter memory retention during power interruption

Sample Compatibility & Compliance

The ZSH.CP-500 accommodates standard T-75, T-175, and multi-well plates within its 500 L chamber volume, with three adjustable stainless-steel shelves (load-rated to 15 kg/shelf). Its uncontrolled humidity architecture aligns with applications where aqueous evaporation is actively managed externally (e.g., via sealed culture vessels or supplemental humidification trays). While not certified to ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, the system supports GLP/GMP-aligned workflows through optional RS485/USB data logging interfaces (with timestamped audit trails), programmable alarm thresholds, and hardware-level over-temperature cut-off. All electrical components comply with IEC 61010-1 safety standards; refrigerant used meets EU F-Gas Regulation (EC) No 517/2014 requirements.

Software & Data Management

The incubator features embedded firmware with real-time display of CO₂ %, chamber temperature, and elapsed cycle time on either monochrome LCD (ZSH series) or full-color capacitive touchscreen (DCP variant). Optional connectivity modules enable integration with laboratory information management systems (LIMS): RS485 output supports Modbus RTU protocol for centralized monitoring, while USB export generates CSV-formatted logs compatible with Excel, MATLAB, or Python-based analysis pipelines. Firmware includes configurable alarm escalation (visual + audible), event-triggered data capture (e.g., door-open duration), and non-volatile memory preserving user-defined parameters across power cycles. No cloud dependency or proprietary software installation is required for basic operation.

Applications

This platform serves diverse life science use cases requiring stable CO₂-tensioned environments: mammalian cell line maintenance (HEK293, CHO, HeLa), primary neuronal culture, stem cell expansion under hypoxic or photo-stimulated conditions, and microbiological co-culture assays where gas-phase interference must be minimized. Its illumination-ready architecture supports chronobiology research (e.g., PER2::LUC reporter assays), photodynamic therapy screening, and plant tissue culture under defined spectral regimes. The absence of active humidity control makes it suitable for applications using gas-permeable membranes (e.g., Transwell inserts) or oil-overlay techniques where internal RH variability does not impact experimental outcomes.

FAQ

Does the ZSH.CP-500 include active humidity control?
No—it operates as a dry CO₂ incubator. Humidity must be managed externally via sealed vessels, water pans, or auxiliary humidification systems.
What is the CO₂ sensor calibration interval recommended by DRETOP?
Annual verification against NIST-traceable reference gas is advised; field recalibration requires IR sensor-specific zero/span gas and service technician access.
Can the incubator maintain sterility during frequent door openings in shared-core facilities?
Yes—the combination of HEPA filtration, rapid CO₂/temperature recovery, and UV sterilization cycles minimizes contamination risk in high-throughput settings.
Is the LED illumination system compatible with fluorescence microscopy workflows?
Red/blue LED arrays emit negligible IR radiation and do not interfere with standard FITC/TRITC filter sets; however, direct optical path alignment requires custom mounting fixtures.
What regulatory documentation is provided with shipment?
CE Declaration of Conformity, IEC 61010-1 test report, RoHS compliance certificate, and factory calibration record are included; ISO 17025 calibration certificates available upon request.
