Labonce Labonce-9050GHP Water-Jacketed Constant Temperature Incubator

Overview

The Labonce Labonce-9050GHP Water-Jacketed Constant Temperature Incubator is engineered for precise, stable thermal environments required in microbiological culture, cell line maintenance, enzyme activity assays, and long-term biological storage. Unlike forced-air incubators, its water-jacketed design provides superior thermal mass and passive heat retention—minimizing temperature overshoot, reducing recovery time after door openings, and delivering exceptional spatial uniformity across the entire chamber. This architecture is especially critical for sensitive applications such as primary cell culture, mycobacterial growth, or anaerobic organism propagation where even transient thermal gradients can compromise viability or experimental reproducibility. The unit operates within a controlled range of RT+5°C to 65°C, making it suitable for both standard mammalian cell culture (e.g., 37°C) and higher-temperature applications including fungal cultivation or thermal stability testing.

Key Features

• Water-jacketed thermal insulation system ensures minimal temperature fluctuation (±0.3°C) and high uniformity (±0.5°C at 37°C), validated per ISO 13408-2 and ASTM E1255 protocols for incubator performance verification.
• Double-door configuration with tempered inner glass door enables real-time observation without compromising chamber integrity or thermal stability.
• Electropolished mirror-finish stainless steel interior (304 grade) with seamless quarter-radius corners facilitates complete decontamination and prevents microbial harborage—meeting GLP-compliant cleaning validation requirements.
• Microprocessor-based digital controller with PID algorithm and programmable timer supports up to 999-hour operation cycles; optional WHI-series touchscreen interface adds role-based access control (administrator/operator/user), electronic signatures, and immutable audit trails compliant with FDA 21 CFR Part 11.
• Exterior housing constructed from cold-rolled steel with epoxy-polyester powder coating resists corrosion and mechanical abrasion in shared laboratory environments.
• Two independently adjustable, load-rated stainless steel shelves included as standard; additional shelves available for modular capacity expansion.

Sample Compatibility & Compliance

The Labonce-9050GHP accommodates standard microbiological vessels—including Petri dishes (up to 150 mm), multi-well plates (6–96-well), culture flasks (T25–T175), and test tubes—without airflow-induced desiccation. Its static thermal environment eliminates convective drying effects common in fan-assisted units, preserving media hydration and preventing edge-effect artifacts in colony isolation studies. The incubator conforms to IEC 61010-1:2010 safety standards for laboratory equipment and incorporates over-temperature protection with independent mechanical backup cutoff. For regulated environments, optional WHI controller firmware supports IQ/OQ documentation templates aligned with ISO/IEC 17025 and EU Annex 11 expectations.

Software & Data Management

While the base model features a stand-alone microcontroller with local display and keypad input, the WHI touchscreen upgrade transforms the system into a network-ready platform. It logs timestamped temperature readings at user-defined intervals (1 s to 60 min), stores ≥12 months of data internally, and exports CSV files via USB or Ethernet. All configuration changes, user logins, alarm events, and calibration actions are recorded in a tamper-evident audit trail with cryptographic hashing. Role-based permissions enforce separation of duties: administrators configure system parameters, operators execute runs, and reviewers validate outputs—fulfilling ALCOA+ data integrity principles for GMP and clinical trial support laboratories.

Applications

• Maintenance of bacterial cultures (e.g., E. coli, S. aureus) and fastidious pathogens requiring tightly buffered thermal conditions.
• Long-term storage of cryopreserved cell stocks post-thaw recovery under non-stressful ambient re-equilibration.
• Enzyme kinetics studies where reaction rates are highly temperature-dependent (e.g., polymerase activity assays).
• Quality control testing of sterile medical devices using biological indicators (e.g., Geobacillus stearothermophilus spore strips).
• Stability assessment of biopharmaceutical intermediates during accelerated aging protocols per ICH Q1A(R2).

FAQ

What is the difference between water-jacketed and air-jacketed incubators?
Water-jacketed incubators use a surrounding layer of heated water to buffer temperature changes, offering slower but more stable thermal response—ideal for uninterrupted long-duration experiments. Air-jacketed units heat air directly, enabling faster setpoint attainment but greater susceptibility to ambient fluctuations.
Can this incubator be used for CO₂-sensitive applications?
No—the Labonce-9050GHP is a non-CO₂, ambient-air incubator. It does not regulate gas composition; users requiring pH-controlled environments must integrate external CO₂ supply systems or select a dedicated CO₂ incubator model.
Is calibration certification available?
Yes—NIST-traceable temperature calibration reports (including as-found/as-left data at three points: 25°C, 37°C, and 55°C) can be provided upon request, supporting ISO/IEC 17025-accredited lab compliance.
Does the unit meet electromagnetic compatibility (EMC) requirements for European laboratories?
Yes—it complies with EN 61326-1:2013 for EMC emissions and immunity, and carries CE marking for unrestricted use within the European Economic Area.
