ZiQi DHP-9162 Electric Constant Temperature Incubator

Overview

The ZiQi DHP-9162 Electric Constant Temperature Incubator is an engineered solution for precise, stable, and reproducible thermal environments in microbiological, cell culture, and general life science applications. Designed around a six-surface direct heating architecture combined with forced-air convection, the unit ensures rapid thermal response and exceptional temperature homogeneity across its 160 L working chamber. Its operational range spans from ambient +5°C to 65°C—optimized for bacterial growth, enzyme activity assays, seed germination studies, and stability testing under non-humidified, non-CO₂ conditions. The incubator complies with fundamental design principles outlined in ISO 13408-1 (aseptic processing) and supports GLP-compliant workflows when integrated with optional data logging and audit-trail-capable software.

Key Features

• High-precision digital PID temperature control system delivering ±0.1°C setpoint accuracy and ±0.5°C uniformity across the full chamber volume under standard test conditions (empty load, 30°C ambient, 50% RH).
• Six-surface electric heating film configuration enables faster warm-up times and minimizes thermal gradients compared to single-wall or bottom-only heating designs.
• Forced convection airflow system with optimized fan placement and baffle geometry ensures consistent air velocity distribution and eliminates cold spots—critical for uniform sample development.
• Dual-door structure with insulated glass window and secondary sealing gasket maintains thermal integrity during observation, reducing heat loss by up to 30% versus single-door alternatives.
• Interior constructed from electropolished mirror-finish stainless steel (AISI 304), featuring radius-cornered walls and removable, height-adjustable shelves for easy cleaning and flexible load configuration.
• Exterior housing fabricated from cold-rolled steel with epoxy-polyester electrostatic powder coating—resistant to abrasion, corrosion, and routine laboratory disinfectants.
• Independent over-temperature safety cutoff circuit (optional) interrupts power if user-defined limit is exceeded—meeting IEC 61010-1 requirements for laboratory equipment safety.

Sample Compatibility & Compliance

The DHP-9162 accommodates standard-sized petri dishes (up to 150 mm), multi-well plates (6–96-well), culture flasks (T25–T225), and glassware up to 500 mL in volume. Its non-humidified chamber is suitable for applications where moisture condensation must be avoided—including dry incubation of desiccated samples, polymer curing validation, and accelerated aging tests per ASTM D3045. The unit meets CE marking requirements for electromagnetic compatibility (EN 61326-1) and low-voltage safety (EN 61010-1). Optional RS485 interface supports integration into centralized lab monitoring systems compliant with FDA 21 CFR Part 11 when paired with validated third-party data acquisition software.

Software & Data Management

While the DHP-9162 operates via standalone front-panel controls, its optional RS485 serial interface enables connection to external data loggers or PC-based supervision platforms. When configured with compliant software, the system supports time-stamped temperature logging, configurable alarm thresholds, electronic signature capture, and exportable CSV/Excel reports—facilitating traceability in QA/QC and regulatory submissions. Audit trail functionality, including user login history and parameter change logs, can be implemented through compatible SCADA or LIMS integrations aligned with ISO/IEC 17025 and GxP documentation standards.

Applications

• Bacterial and fungal colony isolation and enumeration (e.g., ISO 4833-1, AOAC 977.27)
• Enzyme kinetics and thermal stability profiling (e.g., USP <1058> Analytical Instrument Qualification)
• Seed viability and germination rate assessment (ISTA guidelines)
• Pharmaceutical stability testing under long-term and accelerated conditions (ICH Q1A)
• Material degradation studies requiring controlled dry-heat exposure (ASTM E1527)
• Quality assurance of diagnostic reagents and biologics during shelf-life verification

FAQ

What is the recommended calibration interval for the DHP-9162?

Annual calibration using NIST-traceable reference thermometers is advised for GLP/GMP environments; more frequent verification may be required based on internal SOPs or risk assessment.
Can this incubator be used for CO₂-dependent cell cultures?

No—the DHP-9162 is a non-humidified, ambient-air electric incubator without CO₂ regulation or humidity control. For mammalian cell work, consider ZiQi’s CO₂ incubator series (e.g., DHP-CO₂-160).
Is the interior lighting UV-compatible?

The standard model does not include UV sterilization capability; however, optional UV-C lamp modules (254 nm) can be retrofitted with proper safety interlocks and validation protocols.
Does the timer function retain settings after power interruption?

Yes—the embedded memory retains programmed timer values and setpoints following brief power loss, though continuous operation requires uninterruptible power supply (UPS) support for mission-critical runs.
Are spare shelves and door gaskets available as consumables?

Yes—ZiQi supplies certified replacement parts including AISI 304 stainless steel shelves (part #DHP-SH-160), silicone door gaskets (DHP-GSK-160), and calibrated PT100 sensors (DHP-SEN-PT100) with individual calibration certificates.
