Labonce Labonce-9162DHP Water-Jacketed Constant Temperature Incubator

Overview

The Labonce Labonce-9162DHP Water-Jacketed Constant Temperature Incubator is a rigorously engineered environmental chamber designed for precise, stable thermal control in life science laboratories and industrial quality control settings. Unlike forced-air incubators, the Labonce-9162DHP employs an air-jacketed heating architecture—where resistive heating elements surround the insulated chamber wall—to deliver rapid thermal response, minimal temperature overshoot, and high spatial uniformity across the full 160 L working volume. This design ensures consistent heat distribution without internal airflow turbulence, making it especially suitable for applications requiring undisturbed sample environments, such as microbial colony development, enzyme activity assays, and long-term cell maintenance where convection-induced desiccation or mechanical stress must be avoided. The unit operates within a controlled ambient range of +5 °C to +35 °C and maintains setpoints from RT+5 °C to 65 °C, supporting both standard bacteriological cultivation (e.g., at 30 °C or 37 °C) and elevated-temperature stability testing per ICH Q1A(R3) guidelines.

Key Features

• Air-jacketed electric heating system enabling fast warm-up times and reduced thermal lag compared to water-jacketed alternatives—without risk of leakage or maintenance-intensive fluid management.
• Mirror-finish 304 stainless steel interior chamber with seamless, quarter-radius corner welding and electropolished surface finish to prevent microbial adhesion and facilitate ISO 14644-compliant cleaning protocols.
• Microprocessor-based digital controller with 0.1 °C resolution, real-time temperature display, and programmable timer function (up to 999 hours), supporting unattended overnight or multi-day incubation cycles.
• Dual-layer door assembly incorporating a tempered glass inner window—optically clear, low-iron, and thermally insulated—to permit continuous visual monitoring without compromising chamber integrity or thermal stability.
• Six independently adjustable, load-rated stainless steel shelves (standard configuration), each rated for ≥15 kg uniformly distributed load; shelf positions can be reconfigured without tools to accommodate varied vessel heights (e.g., stacked Petri dishes, flasks, or multi-well plates).
• Robust external housing fabricated from cold-rolled steel with epoxy-polyester powder coating (film thickness ≥60 µm), providing corrosion resistance under routine laboratory chemical exposure and mechanical durability for high-traffic facility deployment.

Sample Compatibility & Compliance

The Labonce-9162DHP accommodates standard microbiological and cell culture formats including 100 mm Petri dishes (up to 48 per shelf), 250 mL Erlenmeyer flasks (up to 12 per shelf), and 96-well microtiter plates (up to 8 per shelf). Its static thermal environment meets critical requirements for CLSI M22-A3 and USP microbial recovery validation studies. The device conforms to YY 0027–1990, China’s national standard for electrically heated constant-temperature incubators, and supports alignment with broader international frameworks including ISO/IEC 17025:2017 (for accredited test labs) and GLP principles when operated with documented SOPs and calibrated traceable to NIM (National Institute of Metrology, China). Optional HI-series touchscreen controllers provide configurable user roles (administrator/operator/auditor), electronic signature capability, and time-stamped audit trails compliant with FDA 21 CFR Part 11 Annex 11 expectations.

Software & Data Management

While the base model features a standalone microcontroller interface, the optional HI-series touchscreen upgrade delivers comprehensive data governance functionality. It includes built-in non-volatile memory logging (≥30 days of 1-minute interval records), USB export for CSV-formatted temperature history, and configurable alarm thresholds with relay outputs for integration into BMS or centralized lab monitoring systems. All configuration changes, setpoint modifications, and alarm acknowledgments are immutably logged with user ID, timestamp, and action type—enabling full reconstruction of operational history during regulatory inspections. Data encryption (AES-128) and password-protected firmware updates further support cybersecurity best practices outlined in ISO/IEC 27001 Annex A.8.2.

Applications

• Bacterial and fungal cultivation per ISO 4833-1:2013 and GB 4789.2–2022 standards.
• Stability testing of pharmaceutical intermediates and excipients per ICH Q1A(R3) accelerated conditions (e.g., 40 °C/75% RH via external humidifier coupling).
• Enzyme kinetics assays requiring tight thermal control over extended durations (e.g., lipase or amylase activity profiling).
• Seed germination and plant tissue culture under defined thermoperiod regimes.
• Quality assurance of diagnostic reagents and rapid test kits during shelf-life verification.
• Pre-incubation conditioning of biosensors and electrochemical transducers prior to calibration.

FAQ

What is the difference between air-jacketed and water-jacketed incubation systems?

Air-jacketed designs use insulated perimeter heating elements to maintain chamber temperature, offering faster equilibration, no fluid maintenance, and lower risk of contamination versus water-jacketed units—while still delivering superior uniformity compared to fan-forced convection models.
Can this incubator be validated for GMP environments?

Yes—when equipped with the HI controller and operated with documented IQ/OQ protocols, temperature mapping (per ISO 14644-3), and annual calibration against NIST-traceable references, the Labonce-9162DHP supports compliance with EU GMP Annex 11 and PIC/S PI 007-6 requirements.
Is remote monitoring supported?

The HI controller variant provides RS485 Modbus RTU output and optional Ethernet/Wi-Fi modules for integration with SCADA, LabVantage, or custom MES platforms—enabling real-time status dashboards and automated alerting via SMTP or SNMP traps.
How often does the unit require preventive maintenance?

Annual inspection of heater continuity, door gasket compression force, and controller calibration is recommended; no scheduled lubrication or consumable replacement is required due to solid-state thermal architecture and sealed electronics.
Does the incubator meet electromagnetic compatibility (EMC) requirements for laboratory use?

Yes—the Labonce-9162DHP complies with GB/T 18268.1–2010 (equivalent to IEC 61326-1:2012), ensuring immunity to common lab-grade RF interference and minimal conducted emissions in shared electrical circuits.
