Labonce Labonce-9402DHP Water-Jacketed Constant Temperature Incubator

Overview

The Labonce Labonce-9402DHP Water-Jacketed Constant Temperature Incubator is a precision-engineered environmental chamber designed for stable, uniform thermal control in life science laboratories and industrial R&D settings. Unlike forced-air (fan-assisted) incubators, the Labonce-9402DHP employs an air-jacketed heating architecture—where resistive heating elements surround the insulated chamber cavity—to deliver rapid temperature ramp-up, minimal internal airflow disturbance, and reduced moisture loss during prolonged culture periods. This configuration supports sensitive applications including mammalian cell propagation, microbial growth studies, enzyme activity assays, and stability testing of biologics under ISO 13485-aligned conditions. The unit operates across a controlled range of RT+5 °C to 65 °C, with temperature resolution of 0.1 °C and uniformity maintained within ±1.0 °C at 37 °C—a specification validated per YY 0027-1990, the Chinese national standard for electrically heated constant-temperature incubators.

Key Features

• Air-jacketed electric heating system ensures fast thermal response and minimizes internal convection-induced desiccation—critical for long-term cell monolayer maintenance.
• Mirror-finish 304 stainless steel interior chamber resists corrosion, facilitates cleaning validation, and complies with GLP-compatible surface requirements for traceability in regulated environments.
• Microcomputer-based digital controller with programmable timer function enables repeatable setpoint execution and unattended operation over extended cycles.
• Dual-layer door assembly includes an inner tempered glass window, enabling non-invasive visual monitoring without compromising chamber integrity or thermal stability.
• Three adjustable, load-rated stainless steel shelves (standard configuration) support flexible vessel stacking; all shelves are removable and autoclavable.
• Structural design incorporates rounded internal corners and seamless welds to eliminate microbial harborage points and simplify cleaning verification per FDA Aseptic Processing Guidance.

Sample Compatibility & Compliance

The Labonce-9402DHP accommodates standard laboratory vessels—including Petri dishes, multiwell plates, T-flasks (up to T225), roller bottles, and serum bottles—within its 400 L working volume. Its internal dimensions (640 × 585 × 1355 mm) allow vertical stacking of stacked flasks while preserving ergonomic access. The incubator meets YY 0027-1990 mechanical and safety specifications and conforms to IEC 61010-1 for electrical safety in laboratory equipment. When equipped with the optional HI touchscreen controller (sold separately), the system supports configurable user roles (Administrator, Supervisor, Operator), electronic audit trail logging, and password-protected parameter modification—features aligned with 21 CFR Part 11 readiness for GMP-regulated quality control labs.

Software & Data Management

The base microcontroller provides local real-time display of setpoint, actual temperature, elapsed time, and error status via a high-contrast LED interface. For advanced data governance, the optional HI touchscreen controller introduces embedded data logging (interval-adjustable from 1 min to 24 h), USB export of CSV-formatted temperature history, and event-triggered alerts (e.g., door-open duration exceedance, temperature deviation >±0.5 °C). All logged entries include timestamp, operator ID, and action type—enabling full traceability during internal audits or regulatory inspections under ISO/IEC 17025 or CAP accreditation frameworks.

Applications

• Bacterial and fungal culture maintenance in clinical microbiology and pharmaceutical QC labs.
• Long-duration incubation of primary human cells and stem cell lines requiring low-shear, low-dehydration environments.
• Thermal stability assessment of vaccines, monoclonal antibodies, and diagnostic reagents per ICH Q5C guidelines.
• Enzymatic reaction kinetics studies where precise temperature control directly impacts V_max and K_m reproducibility.
• Seed germination trials and plant tissue culture protocols governed by OECD Test Guidelines 208 and 227.

FAQ

What is the difference between air-jacketed and water-jacketed incubators?
Air-jacketed systems use insulated air gaps and electric heating elements around the chamber—offering faster warm-up, lower maintenance, and no risk of leakage. Water-jacketed units rely on circulating heated water; they provide superior thermal stability but require periodic refilling and antifreeze treatment.
Does the Labonce-9402DHP support remote monitoring or network connectivity?
The standard model does not include Ethernet or Wi-Fi interfaces. However, the optional HI controller supports RS-485 Modbus RTU communication for integration into centralized building management or LIMS platforms via third-party gateways.
Can the incubator be validated for IQ/OQ/PQ protocols?
Yes—the unit’s mechanical construction, sensor placement (PT100 class B), and documented calibration traceability enable full qualification per ASTM E2500 and EU Annex 15. Validation templates and factory calibration certificates are available upon request.
Is humidity control available on this model?
No—this is a dry-air incubator. Humidity management requires external humidification accessories or selection of Labonce’s dedicated CO₂/humidity-controlled incubator series (e.g., Labonce-9402CHP).
What is the warranty coverage and service support structure?
Labonce provides a 24-month limited warranty covering parts and labor for manufacturing defects. Field service engineers are available across major Chinese metropolitan areas; international distributors offer localized technical support and spare parts logistics.
