Overview
The DHP-50 Precision Temperature-Controlled Incubator is a laboratory-grade, convection-heated incubation system engineered for stable, repeatable thermal environments in life science applications. Designed around resistive external heating elements and microprocessor-based PID temperature regulation, the unit maintains setpoint accuracy without overshoot—critical for sensitive biological samples such as microbial cultures, cell lines, and enzyme assays. Unlike forced-air humidified incubators, the DHP-50 operates as a dry, non-humidified thermal chamber, eliminating condensation-related contamination risks and simplifying maintenance protocols. Its structural architecture prioritizes thermal stability over rapid ramping, making it suitable for long-term static incubation where precision and consistency outweigh dynamic control requirements. The device complies with general safety standards for Class II electrical laboratory equipment (IEC 61010-1) and supports routine validation procedures aligned with GLP-compliant workflows.
Key Features
- Microprocessor-controlled digital temperature display with PID algorithm for high reproducibility and minimal drift (±0.5 °C typical stability at 37 °C)
- Externally mounted heating elements to prevent direct radiant exposure of samples—reducing thermal stress on culture vessels and minimizing localized hot spots
- Dual-layer tempered glass observation door with silicone-sealed perimeter, enabling visual monitoring without significant thermal disturbance or ambient air intrusion
- Stainless steel interior chamber with rounded corners and seamless welds for ease of cleaning and reduced microbial retention
- Independent over-temperature protection circuit (mechanical backup thermostat) meeting IEC 60730-1 safety requirements
- Compact footprint (W × D × H ≈ 450 × 450 × 500 mm) optimized for benchtop integration in QC labs, teaching facilities, and field-deployable research units
Sample Compatibility & Compliance
The DHP-50 accommodates standard-sized Petri dishes (90–100 mm), multi-well plates (6–96-well), test tubes (13–16 mm OD), and flasks up to 500 mL. Its uniform airflow design—achieved via natural convection and strategically positioned heat distribution channels—ensures consistent thermal exposure across vertically stacked sample layers. While not certified for ISO 14644-1 cleanroom operation, the unit meets baseline biosafety requirements for BSL-1 and BSL-2 support functions when used in conjunction with appropriate containment practices. It supports calibration traceability per ISO/IEC 17025 guidelines when paired with NIST-traceable reference thermometers. Documentation packages include factory calibration reports and electrical safety test certificates.
Software & Data Management
The DHP-50 operates via embedded firmware with no external software dependency—ensuring operational continuity during network outages or IT policy restrictions. Temperature setpoints, real-time readings, and alarm status are displayed on a 3-digit LED interface with backlighting for low-light environments. Optional RS-232 or USB-to-serial adapters (sold separately) enable connection to data loggers or LIMS platforms for time-stamped temperature recording. Audit trail functionality is limited to manual logbook entries; for full 21 CFR Part 11 compliance—including electronic signatures and immutable records—integration with third-party validated logging systems is recommended.
Applications
- Maintenance of bacterial and fungal stock cultures (e.g., E. coli, S. cerevisiae) at defined temperatures (4 °C to 60 °C range)
- Enzyme activity assays requiring strict thermal control during kinetic measurements
- Seed germination studies in agricultural research under standardized thermal conditions
- Pharmaceutical stability testing per ICH Q1A(R2) guidelines for short-term accelerated conditions (e.g., 40 °C/75% RH alternatives using desiccant-controlled environments)
- Training laboratories for microbiology and molecular biology courses where cost-effective, reliable incubation is essential
FAQ
Does the DHP-50 include humidity control capability?
No—the DHP-50 is a temperature-only incubator. Humidity regulation requires separate humidification modules or alternative models (e.g., DHG series) designed for combined T/RH control.
What is the maximum operating temperature?
The unit is rated for continuous operation up to 60 °C, with factory-set upper limit protection at 65 °C.
Can this incubator be validated for GMP environments?
Yes—though it lacks built-in data logging, its thermal performance, mechanical safety features, and construction materials permit IQ/OQ/PQ qualification when supported by external calibration and documentation protocols.
Is the chamber interior autoclavable?
No—the stainless steel chamber is not designed for autoclave exposure; cleaning is performed using 70% ethanol or approved laboratory disinfectants.
What power supply does the DHP-50 require?
Standard single-phase 220 V AC ±10%, 50 Hz, with a nominal power draw of 350 W.
