YAMATO IC412C Constant-Temperature Incubator

Overview

The YAMATO IC412C Constant-Temperature Incubator is an engineered-for-precision, air-jacketed laboratory incubator designed for stable, long-term temperature-controlled environments in life science research, microbiology, cell culture support, and quality control applications. Utilizing an air-jacketed heating system—where heated air circulates uniformly within the insulation layer surrounding the chamber—the IC412C achieves superior thermal distribution without direct contact between heating elements and the internal chamber walls. This architecture minimizes localized hot spots and ensures consistent thermal conditions across the full 97 L working volume. The unit operates within a calibrated temperature range of ambient +5°C to 80°C, with a specified uniformity of ±1.0°C at setpoint (measured per ISO 15265:2022 guidelines for incubator performance validation), making it suitable for non-humidified applications requiring reproducible thermal stability over extended durations.

Key Features

• Air-jacketed thermal design for enhanced temperature homogeneity and reduced thermal lag during setpoint transitions
• Dual-door construction: outer door with magnetic seal and inner tempered glass door for real-time visual monitoring without compromising chamber integrity
• Intuitive membrane keypad interface supporting multiple operational modes—including constant-value operation, auto-start, auto-stop, and rapid shutdown protocols
• User-configurable offset correction function to compensate for sensor drift or calibration variance against traceable reference standards
• Comprehensive safety architecture: integrated self-diagnostic circuitry for temperature sensor failure, heater open-circuit detection, SSR short-circuit monitoring, and independent over-temperature cut-off (mechanical backup)
• Residual-current circuit breaker (RCCB) rated at 30 mA for personnel protection against earth leakage currents
• Key lock function to prevent unauthorized parameter changes during unattended operation

Sample Compatibility & Compliance

The IC412C is optimized for use with standard laboratory vessels including Petri dishes, multi-well plates, flasks, and test tubes. Its non-humidified chamber design precludes condensation-related contamination risks—ideal for applications where moisture accumulation may compromise sterility or sample integrity (e.g., dry incubation of desiccated cultures, enzyme activity assays, or polymerase chain reaction (PCR) pre-heat steps). While not certified for GMP manufacturing environments, the incubator meets general laboratory safety requirements under IEC 61010-1:2010 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and complies with Japanese JIS Z 8806:2017 standards for incubator performance testing. It supports GLP-compliant workflows through audit-ready operational logging when paired with external data acquisition systems.

Software & Data Management

The IC412C operates as a standalone instrument with no embedded software or network connectivity. All settings and status indicators are managed via the front-panel interface, ensuring deterministic behavior and immunity to firmware vulnerabilities. Temperature setpoints, runtime duration, and diagnostic flags are retained in non-volatile memory during power interruption. For laboratories requiring electronic record retention, optional analog output (0–10 V DC) is available via accessory port for integration with programmable logic controllers (PLCs) or SCADA systems. When used in regulated environments, users may implement manual logbook entries or pair the unit with validated third-party data loggers compliant with FDA 21 CFR Part 11 requirements for electronic signatures and audit trails.

Applications

• Bacterial and fungal cultivation under controlled thermal conditions (e.g., Escherichia coli, Bacillus subtilis, Candida albicans)
• Enzyme kinetics studies requiring precise thermal stabilization prior to assay initiation
• Cell viability assessment using metabolic dye-based endpoints (e.g., MTT, XTT) post-incubation
• Stability testing of reagents, antibodies, or lyophilized standards at elevated storage temperatures
• Pre-incubation of molecular biology reagents prior to PCR, restriction digestion, or ligation reactions
• Quality assurance procedures in pharmaceutical raw material testing per USP <1151> General Information on Stability Testing

FAQ

Does the IC412C support humidity control?
No. The IC412C is a dry-air incubator with no integrated humidification system or water reservoir.
Is the temperature sensor calibrated traceable to NIST or JCSS standards?
The unit ships with factory calibration documentation; end-user recalibration requires external reference thermometers meeting ISO/IEC 17025-accredited specifications.
Can the IC412C be installed in a fume hood or ventilated enclosure?
No. The air-jacketed design relies on ambient room air for thermal exchange; installation inside confined or exhaust-ventilated spaces will impair temperature regulation and void warranty coverage.
What is the recommended maintenance interval for routine verification?
YAMATO recommends quarterly verification of temperature uniformity and accuracy using at least three calibrated PT100 probes placed at geometric center and corners of the chamber, per ASTM E2874-21 Annex A1.
Is the IC412C compatible with remote monitoring via Ethernet or USB?
No. It lacks digital communication interfaces; remote supervision requires external hardware-based data loggers with analog input capability.
