Labonce Labonce-9052DHP Water-Jacketed Constant Temperature Incubator

Overview

The Labonce Labonce-9052DHP Water-Jacketed Constant Temperature Incubator is an air-jacketed, microprocessor-controlled laboratory incubation system engineered for stable thermal environments in life science research, pharmaceutical quality control, and biotechnological process development. Unlike water-jacketed designs—which rely on thermal mass from surrounding water layers—the Labonce-9052DHP employs an air-jacketed heating architecture: a thermally insulated chamber envelope with electric heating elements distributed across the outer wall surface. This configuration enables rapid temperature ramp-up, reduced energy consumption during steady-state operation, and improved resistance to ambient fluctuations—particularly valuable in non-climate-controlled lab spaces. Designed to meet YY 0027–1990 (Chinese industry standard for electric constant-temperature incubators), the unit delivers precise, repeatable thermal performance across its full operating range of RT+5 °C to 65 °C, supporting applications including microbial culture, enzyme activity assays, cell line maintenance, and stability testing under accelerated conditions.

Key Features

• Air-jacketed electric heating system with optimized heat distribution for fast equilibration and low thermal inertia
• Mirror-finish 304 stainless steel interior chamber—corrosion-resistant, non-porous, and compliant with ISO 14644-1 Class 7 cleanroom-compatible cleaning protocols
• Powder-coated cold-rolled steel exterior with reinforced structural rigidity and chemical-resistant finish
• Microcomputer-based digital temperature controller featuring 0.1 °C resolution, real-time deviation display, and programmable timer (up to 999 hours)
• Dual-layer door assembly with internal tempered glass viewport—minimizes heat loss while enabling non-invasive visual monitoring without door opening
• Two independently adjustable stainless steel shelving units; load capacity per shelf: ≤15 kg (evenly distributed)
• Thermal uniformity validated at ±1.0 °C (measured per ISO 13843:2017 Annex B at 37 °C using 9-point sensor mapping)

Sample Compatibility & Compliance

The Labonce-9052DHP accommodates standard microbiological vessels—including Petri dishes (up to 150 mm diameter), test tubes (16–25 mm OD), Erlenmeyer flasks (up to 1000 mL), and multi-well plates—without interference from shelf geometry or airflow obstruction. Its internal chamber geometry (415 × 360 × 355 mm) supports vertical stacking of stacked plate racks and modular incubation trays. The unit conforms to YY 0027–1990 requirements for temperature accuracy, insulation integrity, and electrical safety. While not certified to IEC 61010-1 or UL 61010-1 out-of-the-box, its design principles align with risk-based validation frameworks used in GLP and GMP environments. When equipped with the optional HI-series touchscreen controller, the system supports electronic record retention, user-level access control (Administrator/Operator/Viewer), and time-stamped audit trail generation—facilitating compliance with FDA 21 CFR Part 11 and EU Annex 11 data integrity expectations.

Software & Data Management

The base model features a standalone microcontroller with LED display and tactile keypad interface—requiring no external software or drivers. For enhanced traceability, the optional HI-series touchscreen controller provides a web-enabled embedded OS with local data logging (CSV export via USB), configurable alarm thresholds (high/low/temp deviation), and event-driven notifications (audible alert + visual indicator). All parameter changes, door openings, and temperature excursions are timestamped and stored in a tamper-evident binary log file. The controller firmware supports periodic calibration verification prompts and allows manual entry of calibration offset values—supporting routine IQ/OQ/PQ documentation workflows. No cloud connectivity or remote access is enabled by default; all data remains resident on-device unless explicitly exported.

Applications

• Bacterial and fungal culture propagation in clinical microbiology and food safety labs
• Short-term mammalian cell passaging where CO₂ control is unnecessary (e.g., HEK293, CHO-K1 suspension cultures)
• Enzymatic reaction kinetics studies requiring isothermal conditions between 25–60 °C
• Accelerated stability testing per ICH Q1A(R2) guidelines (e.g., 40 °C/75% RH stress chambers when paired with external humidity module)
• Seed germination and plant tissue culture pre-incubation in agricultural research
• Quality assurance of raw materials and intermediates in non-sterile pharmaceutical manufacturing

FAQ

What is the difference between air-jacketed and water-jacketed incubators?
Air-jacketed systems use insulated air gaps and electric heating elements for thermal regulation—offering faster warm-up times and lower maintenance than water-jacketed units, which rely on circulating heated water around the chamber.
Does the Labonce-9052DHP support humidity control?
No—this model is designed exclusively for dry-heat incubation. Humidity management requires integration with external humidification accessories or selection of a dedicated humidified incubator platform.
Can the incubator be validated for GMP use?
Yes—when configured with the HI-series controller and operated within documented SOPs, it supports IQ/OQ execution per ASTM E2500 and ISPE Baseline Guide principles. Calibration certificates and probe mapping reports must be generated using NIST-traceable equipment.
Is the stainless steel interior electropolished?
No—the interior uses mechanically polished 304 stainless steel with Ra ≤ 0.8 µm surface roughness, suitable for routine disinfection with 70% ethanol or quaternary ammonium compounds.
What is the maximum ambient temperature for safe operation?
The unit is rated for continuous operation in ambient environments between +5 °C and +35 °C. Operation above 35 °C may compromise temperature uniformity and controller longevity.
