Overview
The DRETOP ZDP-9272 Electric Constant Temperature Incubator is a precision-engineered laboratory incubation system designed for stable, long-term thermal conditioning of biological samples under controlled ambient conditions. Utilizing direct-heated air-jacketed architecture with natural convection airflow, the unit maintains uniform thermal distribution without forced-air turbulence—critical for sensitive cell cultures, microbial growth studies, and enzymatic assays where mechanical agitation or airflow-induced desiccation must be avoided. Its operational range spans from ambient +2°C to 65°C, making it suitable for both mesophilic bacterial cultivation (e.g., E. coli at 37°C) and thermotolerant applications such as fungal propagation or accelerated stability testing. The incubator complies with fundamental design principles outlined in ISO 13408-1 (sterile processing of medical devices) and supports GLP-aligned workflows through traceable temperature control and parameter retention.
Key Features
- Intelligent digital PID temperature controller with 0.1°C resolution and real-time display of setpoint, actual temperature, and elapsed time on a large-backlit LCD interface.
- Air-jacketed heating system with embedded electric heating film uniformly distributed across inner chamber walls—enabling rapid warm-up (<15 min to reach 37°C from 25°C) and minimal thermal overshoot.
- Stainless steel interior chamber (304 grade) with fully removable, height-adjustable stainless steel shelves; seamless corners and smooth welds prevent microbial entrapment and simplify autoclave-compatible cleaning.
- Dual-door observation window: outer magnetic seal door with thermal insulation foam core; inner tempered glass door providing visual monitoring without compromising chamber integrity.
- Robust safety architecture including over-temperature alarm (user-definable threshold), automatic power recovery after outage, and non-volatile memory retaining all settings during power interruption.
- Electrostatically coated cold-rolled steel exterior with rounded corner design enhancing structural rigidity and resistance to impact damage in shared lab environments.
Sample Compatibility & Compliance
The ZDP-9272 accommodates standard microbiological vessels—including Petri dishes (up to 150 mm), culture flasks (T75–T225), test tubes, and multi-well plates—without spatial interference. Its natural convection design eliminates airflow shear stress, preserving fragile monolayer cultures and minimizing evaporation from open containers. The unit meets essential electrical safety requirements per IEC 61010-1 and incorporates grounding continuity verification. While not certified for sterile barrier applications per ISO 14644, its sealed construction and optional UV germicidal lamp (accessory) support ISO 14698-1 compliant biocontamination control protocols. Temperature validation reports may be generated using external calibrated loggers aligned with ASTM E2874 practices.
Software & Data Management
The base configuration operates via standalone hardware control; however, optional RS485 serial interface enables integration into centralized lab monitoring systems (e.g., LabVantage, Siemens Desigo CC). When paired with DRETOP’s optional programmable controller, users can define up to 30 segmented temperature profiles with ramp/soak logic and timestamped event logging. All parameter changes are recorded with operator ID (via keypad entry) and time stamp—supporting audit trails required under FDA 21 CFR Part 11 when used in regulated QC/QA environments. Data export is supported via USB or RS485-to-USB adapter for CSV-formatted temperature history files compatible with Excel or statistical process control (SPC) platforms.
Applications
- Bacterial and yeast culture maintenance in academic and industrial microbiology labs.
- Enzyme activity assays requiring precise thermal stabilization between 30–60°C.
- Seed germination and plant tissue culture under non-photoperiodic conditions.
- Long-term stability testing of pharmaceutical intermediates per ICH Q1A(R2).
- Environmental simulation for aquatic microbiota studies (e.g., wastewater treatment bioassays).
- Pre-incubation of ELISA plates and Western blot transfer membranes prior to hybridization steps.
FAQ
What is the recommended calibration frequency for this incubator?
Annual calibration against NIST-traceable reference thermometers is advised; internal sensor verification should occur before each critical experiment using a calibrated handheld probe.
Can the ZDP-9272 operate continuously for 72+ hours?
Yes—the unit is rated for unattended 24/7 operation with thermal cut-off protection and continuous duty-cycle-rated heating elements.
Is humidity control available as an option?
No; the ZDP series is strictly temperature-controlled. For humidified incubation, consider DRETOP’s HZP-series CO₂ incubators with integrated humidity management.
Does the incubator meet CE or UL certification standards?
It carries CCC (China Compulsory Certification); CE marking is available upon request for EU-distributed units with modified power supply compliance.
How many shelf levels can be installed simultaneously?
Up to four adjustable stainless steel shelves (included) fit within the 270 L chamber, with minimum vertical spacing of 120 mm between levels.
