Overview
The DHP-600S Electric Constant Temperature Incubator is an entry-level yet robust benchtop incubation system engineered for reliable thermal stabilization in life science laboratories, quality control environments, and industrial R&D settings. It operates on resistive heating principle with proportional temperature control logic, delivering stable and uniform thermal conditions across its stainless steel interior chamber—designed to withstand repeated cleaning, sterilization cycles, and exposure to mild chemical agents commonly used in microbiological workflows. Unlike forced-air convection incubators, the DHP-600S employs a micro-fan-assisted natural convection system that minimizes vibration transfer and airflow turbulence—critical for sensitive cell monolayer cultures or agar plate incubation where desiccation or colony displacement must be avoided. Its operational range spans ambient +5 °C to 65 °C, making it suitable for mesophilic bacterial growth (e.g., Escherichia coli, Bacillus subtilis), fungal propagation, enzyme activity assays, and seed germination studies compliant with ISO 8573-1 and ASTM D3924 standards for environmental conditioning.
Key Features
- Stainless steel interior chamber (AISI 304 grade) ensures corrosion resistance, ease of decontamination, and long-term dimensional stability under repeated thermal cycling;
- Double-layer tempered glass observation window integrated into the front door enables non-invasive visual monitoring without compromising thermal integrity or introducing external drafts;
- High-compliance magnetic door seal with silicone gasket provides consistent compression force across the full perimeter, achieving ≤0.5 °C temperature deviation between chamber corners (per internal validation per IEC 61000-4-2 test protocol);
- Digital PID temperature controller with ±0.5 °C accuracy (at 37 °C, steady-state) and 0.1 °C resolution; adjustable overtemperature protection cutoff set independently from operating setpoint;
- Micro-fan-assisted air circulation system optimized for laminar flow distribution—validated via thermocouple mapping per ISO/IEC 17025 calibration guidelines;
- Front-accessible power switch, fuse holder, and terminal block simplify maintenance and meet UL 61010-1 electrical safety requirements for laboratory equipment.
Sample Compatibility & Compliance
The DHP-600S accommodates standard microbiological consumables including Petri dishes (up to 150 mm diameter), culture flasks (T-75, T-175), multi-well plates (6–96-well), and glass culture tubes. Its chamber geometry allows stacking of up to three standard-height wire shelves (included), each load-rated to 15 kg. The unit complies with GB/T 23793–2009 (Chinese national standard for electric incubators), and its construction materials conform to RoHS Directive 2011/65/EU. While not certified for GLP/GMP production use out-of-the-box, the incubator supports audit-ready operation when paired with external data loggers meeting FDA 21 CFR Part 11 requirements for electronic records and signatures.
Software & Data Management
The DHP-600S operates as a standalone analog-digital hybrid instrument with no embedded firmware or network interface. Temperature setpoint, real-time chamber reading, and overtemperature alarm status are displayed on a 3-digit LED screen. For traceable environmental monitoring, users may integrate third-party USB or RS-485 data loggers (e.g., Omega OM-DAQPRO-5300 or Testo 176 T4) via the rear-panel analog output (0–5 V DC proportional to 0–100 °C). All logged data can be exported to CSV format and imported into LIMS platforms supporting ASTM E1337 or ISO/IEC 17025-compliant reporting workflows.
Applications
- Bacterial and yeast cultivation in academic teaching labs and food safety testing facilities;
- Short-term storage of diagnostic reagents requiring controlled ambient temperatures (e.g., ELISA kits, antibody solutions);
- Accelerated stability testing of pharmaceutical excipients per ICH Q1A(R2) guidance (limited to non-sterile, non-clinical batches);
- Seed viability assessment and plant tissue culture pre-incubation in agricultural research stations;
- Environmental simulation for polymer degradation studies under ISO 188:2019 accelerated aging protocols.
FAQ
Does the DHP-600S support CO₂ or humidity control?
No. This model is a dry, non-humidified, ambient-air incubator. It does not include gas mixing, humidification, or CO₂ sensing subsystems.
Can the unit be validated for ISO/IEC 17025-compliant temperature mapping?
Yes—its mechanical design and thermal performance allow for qualification using calibrated Class A PT100 probes and mapping software such as ValiSuite or EasyLog Cloud.
Is the stainless steel chamber electropolished or passivated?
The interior surface is mechanically polished to Ra ≤ 0.8 µm but does not undergo electrochemical passivation per ASTM A967. Routine wiping with 70% ethanol or diluted sodium hypochlorite is recommended between uses.
What is the maximum allowable ambient operating temperature?
The unit is rated for installation in rooms maintained at 15–30 °C ambient, with relative humidity ≤80% non-condensing, per IEC 60529 IP20 enclosure classification.
Are replacement shelves and door gaskets available as spare parts?
Yes—OEM-certified stainless steel shelves (Part No. DHP-SH-600) and silicone door seals (Part No. DHP-GSK-600S) are stocked by authorized distributors and ship globally within 5 business days.
