YAMATO IC912C Forced-Air Constant-Temperature Incubator

Overview

The YAMATO IC912C is a high-capacity, forced-air constant-temperature incubator engineered for long-term, stable thermal environments in life science laboratories. Designed using jacketed air circulation architecture—where heated ambient air is actively distributed via a fan-driven convection system—the IC912C achieves superior temperature homogeneity across its 567 L stainless-steel chamber. Unlike water-jacketed units, this air-jacketed design enables rapid thermal response, reduced maintenance overhead, and consistent performance under varying ambient conditions. The incubator operates within a precise temperature range of ambient +5°C to 80°C, with certified uniformity of ±1.0°C at setpoint (measured per ISO 15263:2019 guidelines using 9-point probe mapping at mid-chamber load condition). Its robust construction, dual-door insulation system, and thermally optimized chamber geometry support uninterrupted operation for cell culture, microbiological assays, enzyme kinetics, and stability testing protocols requiring extended dwell times.

Key Features

• Forced-air convection system with rear-mounted centrifugal blower ensures uniform airflow distribution and minimizes thermal stratification.
• Dual-door structure: outer door with magnetic seal and inner tempered glass door reduces heat loss by up to 35% compared to single-door configurations, improving energy efficiency and setpoint stability.
• Intuitive microprocessor-based controller with large backlit LCD display supports intuitive parameter entry, real-time monitoring, and multi-step program storage.
• Comprehensive safety architecture includes self-diagnostic routines for sensor failure detection, heater open-circuit monitoring, SSR short-circuit protection, independent mechanical over-temperature cut-off (adjustable up to 90°C), and residual-current circuit breaker (RCCB) rated at 30 mA.
• User-configurable operational modes: constant-setpoint operation, timed start/stop, automatic shutdown after user-defined duration, and fast cool-down override function.
• Calibration offset adjustment (±9.9°C range) and keypad lockout functionality enhance operational traceability and prevent unauthorized parameter changes.

Sample Compatibility & Compliance

The IC912C accommodates standard laboratory vessels including Petri dishes, multi-well plates, roller bottles, and Erlenmeyer flasks on adjustable stainless-steel shelves (standard configuration: 4 shelves, load capacity ≤15 kg per shelf). Chamber interior dimensions (W×D×H): 850 × 650 × 1050 mm; door opening height: 920 mm—enabling compatibility with stacked plate racks and automated handling accessories. The unit complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and carries CE marking under the EU Low Voltage Directive and EMC Directive. While humidity control is not integrated, the sealed chamber design maintains internal vapor equilibrium during non-volatile sample storage. It meets general requirements for GLP-compliant environments when paired with external validation protocols (e.g., IQ/OQ/PQ per ASTM E2500-13).

Software & Data Management

The IC912C operates as a standalone instrument without embedded data logging or network connectivity. All operational parameters—including setpoint, actual chamber temperature, elapsed time, and alarm status—are displayed locally. For regulatory traceability, users may integrate optional third-party temperature data loggers (e.g., compliant with FDA 21 CFR Part 11 when used with validated software platforms). YAMATO provides calibration documentation and factory verification reports upon request, supporting audit readiness in QA/QC and clinical research settings.

Applications

• Mammalian and insect cell culture maintenance at physiological or elevated temperatures (e.g., 37°C, 42°C).
• Bacterial and fungal growth studies under controlled thermal conditions (e.g., E. coli, S. cerevisiae, A. niger).
• Enzyme activity assays requiring strict thermal consistency over multi-hour durations.
• Accelerated stability testing per ICH Q1A(R2) guidelines for pharmaceutical intermediates.
• Long-term storage of temperature-sensitive reagents, antibodies, and lyophilized standards.
• Pre-incubation conditioning of materials prior to downstream analytical workflows (e.g., HPLC sample prep, ELISA plate coating).

FAQ

Does the IC912C support humidity control?
No. The IC912C is a dry-air incubator and does not include humidification or dehumidification systems.
Can the chamber temperature be calibrated in-house?
Yes—users may apply a programmable temperature offset (±9.9°C) to correct minor deviations against a NIST-traceable reference thermometer.
What is the maximum shelf loading weight?
Each of the four standard stainless-steel shelves supports up to 15 kg when evenly distributed.
Is the unit suitable for use in cleanroom environments?
The IC912C meets ISO 14644-1 Class 8 (100,000) particulate limits when operated with HEPA-filtered supply air; however, it is not classified as a cleanroom-grade device.
Are replacement parts and service manuals available internationally?
Yes—YAMATO Technical Support provides global spare parts distribution and authorized service network access through regional partners.
