Overview
The DHP-360BS Electric Constant Temperature Incubator is a laboratory-grade, convection-heated incubation system engineered for stable, uniform thermal environments required in microbiological culture, cell propagation, enzyme activity assays, and quality control testing across life science, food safety, agricultural research, and clinical diagnostics laboratories. It operates on resistive heating combined with a micro-fan-assisted air circulation system to minimize thermal gradients—ensuring temperature homogeneity within ±0.5 °C across the stainless steel interior chamber (420 × 360 × 360 mm). The unit complies with fundamental thermal stability requirements outlined in ISO 13408-2 (sterile processing of medical devices), ASTM E171 (standard specifications for environmental chambers), and supports GLP-compliant workflows when integrated into validated lab environments.
Key Features
- Stainless steel interior chamber (AISI 304 grade) — corrosion-resistant, non-porous, and compliant with cleaning validation protocols for repeated sterilization cycles;
- Dual-layer tempered glass observation window — provides optical clarity without compromising thermal integrity or operator safety;
- Precision analog or digital temperature controller (±0.1 °C resolution, ±0.5 °C accuracy over 0–65 °C range) with over-temperature cut-off protection;
- Integrated micro-fan circulation system — enhances convective heat transfer and reduces vertical/horizontal temperature deviation to ≤±0.8 °C at setpoint;
- Magnetic or silicone rubber door gasket — ensures >95% sealing efficiency under ambient conditions, minimizing humidity loss during prolonged incubation;
- Robust sheet metal housing with powder-coated finish — designed for long-term operation in shared core facilities and regulated production labs.
Sample Compatibility & Compliance
The DHP-360BS accommodates standard Petri dishes (up to 150 mm), multi-well plates (6–96-well), test tubes (13–18 mm OD), and culture flasks (T25–T75), with adjustable stainless steel shelving supporting up to 3 tiers. Its stainless steel chamber meets USP criteria for non-shedding surfaces in sterile process simulation studies. While not certified for Class II biosafety applications, it satisfies prerequisite environmental controls for ISO 14644-1 Class 8 cleanroom-adjacent use. The unit’s electrical design conforms to IEC 61010-1:2010 for laboratory equipment safety, including insulation resistance (>2 MΩ), leakage current (<0.75 mA), and dielectric strength (1500 V AC for 1 min).
Software & Data Management
The base DHP-360BS model features standalone analog/digital temperature control without embedded data logging. However, it is compatible with external USB or RS-232-connected data loggers (e.g., Omega OM-DAQPRO-5300 series) for continuous temperature recording and CSV export. When deployed in GxP-regulated environments, users may integrate third-party validation packages supporting 21 CFR Part 11-compliant audit trails—including user authentication, electronic signatures, and immutable timestamped records. Optional upgrades include PID-controlled digital displays with password-protected parameter locking, suitable for SOP-driven QC laboratories.
Applications
- Bacterial colony enumeration (ISO 4833-1:2013, AOAC 977.27);
- Fungal growth assessment in food and feed matrices (EN 15785:2010);
- Seed germination and plant tissue culture in agronomy labs;
- Enzyme kinetics and protein stability studies requiring isothermal conditions;
- Pre-incubation of media prior to autoclaving validation (e.g., nutrient agar, Sabouraud dextrose agar);
- Environmental stress testing of probiotic strains under controlled thermal regimes.
FAQ
What is the maximum operating temperature of the DHP-360BS incubator?
The unit is rated for continuous operation from ambient +5 °C to 65 °C, with optimal stability maintained between 25–45 °C.
Is the stainless steel chamber electropolished or passivated?
Standard configuration uses brushed AISI 304 stainless steel; electropolishing is available as a custom option per order specification.
Can this incubator be used for CO₂-independent cell culture?
Yes—provided humidity is externally managed (e.g., via water tray), the DHP-360BS supports short-term maintenance of adherent mammalian lines such as HEK293 or CHO-K1 under ambient air conditions.
Does the unit include calibration documentation?
Factory calibration certificate (traceable to NIM, China) is provided; ISO/IEC 17025-accredited calibration services are available upon request.
What is the mean time between failures (MTBF) under typical lab usage?
Based on field data from 2020–2023 deployments, MTBF exceeds 12,000 hours with scheduled preventive maintenance every 18 months.
