ZiQi DHP-9052 Electric Constant Temperature Incubator

Overview

The ZiQi DHP-9052 Electric Constant Temperature Incubator is a precision-engineered laboratory incubation system designed for stable, uniform thermal environments in microbiological, cell culture, and biochemical applications. It operates on the principle of forced-air convection combined with six-surface direct heating—ensuring rapid thermal equilibration and minimal spatial temperature gradients across the 50 L working chamber. Engineered for reliability in routine QC labs, academic research facilities, and clinical testing environments, the DHP-9052 maintains setpoint accuracy within ±0.5 °C under standard ambient conditions (30 °C, 50% RH, no vibration or electromagnetic interference), with digital PID control delivering consistent thermal regulation at 0.1 °C resolution. Its robust architecture supports continuous operation over extended periods while meeting fundamental safety and performance expectations for Class II general-purpose incubators per ISO 13485-aligned manufacturing practices.

Key Features

• Backlit LCD interface displaying real-time temperature, setpoint, timer status, and system diagnostics—all visible in a single view with intuitive menu navigation.
• Dual-door design with high-efficiency thermal insulation; outer door features tempered glass for observation without compromising internal thermal stability.
• Mirror-finish stainless steel interior with seamless, radius-corner construction (R ≥ 15 mm) to prevent microbial retention and simplify cleaning validation protocols.
• Electrostatically powder-coated cold-rolled steel exterior for corrosion resistance and mechanical durability in shared lab environments.
• Six-surface electric film heating elements ensure uniform heat distribution and reduce warm-up time by up to 40% compared to single-wall heated alternatives.
• Two independently adjustable stainless steel shelves accommodate varied vessel configurations—including Petri dishes, flasks, and multi-well plates—without tools.
• Optional independent over-temperature safety cutoff provides hardware-level protection compliant with IEC 61000-4-2 ESD immunity requirements.
• RS485 serial interface enables integration with external data loggers or LIMS platforms for audit-ready temperature traceability (optional configuration).

Sample Compatibility & Compliance

The DHP-9052 accommodates standard laboratory containers up to 150 mm in height and supports common sterilization methods including autoclaving of removable shelves and alcohol-based surface disinfection of interior surfaces. Its operating range (RT + 5 °C to 65 °C) aligns with ASTM E1545-19 for thermal stability verification of incubators used in pharmaceutical stability studies and USP recommendations for non-refrigerated storage simulation. While not certified for GMP production environments, the unit meets essential design criteria referenced in ISO 15195:2013 (laboratory incubator performance specifications) and supports GLP-compliant documentation when paired with validated external logging systems. No CO₂, humidity, or UV functionality is integrated—this is a dedicated dry-heat constant-temperature platform.

Software & Data Management

The DHP-9052 does not include embedded software or touchscreen OS; instead, it relies on firmware-controlled PID logic executed via microprocessor-based circuitry with EEPROM-stored calibration offsets. When equipped with the optional RS485 interface, users may connect third-party data acquisition systems (e.g., Campbell Scientific CR1000, Omega OM-DAQPRO-5300) to capture timestamped temperature logs at user-defined intervals. Raw output is ASCII-formatted serial data compatible with CSV import into Excel, MATLAB, or LabVIEW. For regulated environments requiring electronic record integrity, integration with 21 CFR Part 11-compliant platforms requires supplementary validation of the host logging system—not the incubator itself—as the device lacks onboard audit trail, user authentication, or electronic signature capability.

Applications

• Bacterial and fungal culture maintenance at standardized temperatures (e.g., 30 °C for Aspergillus niger, 37 °C for E. coli).
• Enzyme activity assays requiring precise thermal control during kinetic measurements.
• Seed germination and plant tissue culture pre-incubation steps where humidity control is managed externally.
• Stability testing of reagents, buffers, and diagnostic kits under accelerated thermal conditions.
• Quality control workflows in food safety labs (e.g., APC enumeration per ISO 4833-1:2013) and environmental monitoring programs.
• Pre-warming of media, pipette tips, and consumables prior to aseptic procedures.

FAQ

Is the DHP-9052 suitable for cell culture applications requiring CO₂ or humidity control?
No. This is a dry-heat, ambient-air incubator. It lacks CO₂ regulation, humidification, or condensation management systems required for mammalian cell culture.
What is the maximum load capacity for uniform temperature distribution?
Uniformity testing per ISO 15195 confirms ≤ ±0.8 °C deviation across the full chamber volume at 37 °C with 2 shelves loaded at 70% capacity (e.g., 12 × 100 mm Petri dishes per shelf).
Can the unit be validated using IQ/OQ protocols?
Yes—its mechanical and electrical design permits installation qualification (IQ) and operational qualification (OQ) using standard thermocouple mapping procedures and NIST-traceable reference probes.
Does the timer function power-cycle the unit upon completion?
No. The timer deactivates heating only; the fan remains operational, and the display stays active. Power interruption requires manual restart.
Are spare parts such as shelves and door gaskets available internationally?
Yes—ZiQi supplies OEM-certified replacement components globally through authorized distributors, with lead times averaging 4–6 weeks ex-warehouse Shanghai.
