TAITEC M-230FN Medium-Sized Programmable Temperature-Controlled Chamber

Overview

The TAITEC M-230FN is a medium-capacity, microprocessor-controlled temperature chamber engineered for stable, energy-efficient environmental conditioning in research and quality control laboratories. Designed around a three-directional PID temperature regulation architecture, the chamber employs an on/off cycling strategy—activating either the dual 200 W heating elements or the 160 W hermetic air-cooled compressor (R134a refrigerant)—based on real-time deviation between setpoint and measured internal temperature. This intelligent thermal management significantly reduces standby power consumption compared to continuously operating compressor systems, making it suitable for extended unattended operation. The chamber maintains a uniform thermal environment across its 233 L interior volume (638 × 416 × 880 mm), with typical temperature stability of ±1.0–2.0°C under steady-state conditions. Its robust construction features corrosion-resistant interior panels composed of color-coated steel and SUS304 stainless steel, ensuring long-term integrity in humid or chemically exposed environments.

Key Features

• Integrated dual-purpose internal power outlets (2 × 100 V / 3 A) enabling in-chamber operation of compatible ancillary devices—including orbital shakers, rotators, and small incubation accessories—without external cable routing.
• Optional illumination module with four independently switchable 20 W fluorescent lamps; intensity adjustable via dimmer circuitry to deliver up to ~6800 lux at working height, supporting photobiological applications such as plant tissue culture or light-dependent microbial assays.
• Sliding door mechanism equipped with a mechanical key-operated lock and removable activity latch, providing physical access control compliant with laboratory security protocols for sensitive or regulated samples.
• Energy-optimized thermal control logic that eliminates continuous compressor runtime—reducing electrical load and thermal stress on refrigeration components while maintaining target stability within specification.
• Axial-flow internal fan ensures homogeneous air circulation without turbulent flow patterns, minimizing vibration transmission to placed equipment and supporting compatibility with precision instruments requiring low mechanical disturbance.

Sample Compatibility & Compliance

The M-230FN accommodates standard laboratory ware including stacked petri dishes, multi-well plates, conical tubes, and glassware up to 60 kg total shelf loading capacity. Its interior layout supports modular shelving (two adjustable shelves included) and optional accessory integration—e.g., mounting brackets for rotating mixers used in immunoprecipitation workflows or platform adapters for benchtop shakers employed in bacterial or suspension cell culture. The chamber complies with JIS Z 8701 (Japanese Industrial Standard for Environmental Test Equipment) and meets general safety requirements per IEC 61010-1 for laboratory electrical equipment. While not certified for medical device manufacturing, its temperature repeatability and traceable calibration support GLP-aligned documentation when paired with external NIST-traceable thermometers (supplied standard).

Software & Data Management

The M-230FN operates via an embedded digital controller with LED display and tactile keypad interface; no proprietary software or PC connectivity is provided. All operational parameters—including setpoint, actual temperature, lamp status, and alarm history—are retained in non-volatile memory during power interruption. The system logs overtemperature/undertemperature events and compressor cycle count for maintenance tracking. For regulatory environments requiring audit trails, users may integrate third-party data loggers (e.g., compliant with FDA 21 CFR Part 11) via the internal 100 V outlets or external sensor ports (available as optional accessories). Calibration verification is supported using the supplied calibrated mercury-in-glass thermometer (±0.5°C accuracy) and optional PT100 probe inputs.

Applications

• Long-term storage of temperature-sensitive reagents, antibodies, and biological standards at defined ambient or sub-ambient conditions (+3°C to +45°C).
• Controlled-environment incubation of microbial cultures, yeast, or plant callus tissues—particularly when combined with synchronized orbital shaking or end-over-end rotation for enhanced aeration and nutrient distribution.
• Immunoassay preparation workflows requiring consistent low-speed agitation during antibody–antigen binding phases, enabled by in-chamber integration of rotating mixers.
• Photoperiod-controlled experiments in plant physiology, algal growth studies, or circadian rhythm assays leveraging the programmable illumination subsystem.
• Stability testing of pharmaceutical intermediates or diagnostic kits under ICH Q1A-recommended storage conditions (e.g., 25°C/60% RH simulated via dry operation).

FAQ

Can external sensors be connected for remote monitoring?
Yes—optional analog voltage or RS-485 output modules are available from TAITEC for integration with building management systems or centralized lab monitoring platforms.
Is the chamber suitable for use with CO₂-sensitive cell cultures?
No—the M-230FN provides only temperature and optional light control; it does not regulate CO₂, O₂, or humidity. For such applications, a dedicated CO₂ incubator is required.
What maintenance is recommended for the refrigeration system?
Annual inspection of condenser coil cleanliness and verification of refrigerant charge integrity by authorized service personnel is advised; no user-serviceable components exist within the sealed compressor unit.
Are replacement shelves or custom interior configurations available?
Yes—SUS304 wire mesh shelves, reinforced load-bearing trays, and lamp diffuser kits can be ordered separately under TAITEC part numbers M-230-SH-SS and M-230-LAMP-DIFF.
Does the unit comply with electromagnetic compatibility (EMC) directives for EU laboratories?
The M-230FN meets EN 61326-1:2013 for EMC in laboratory environments and carries the CE marking for equipment placed on the European market prior to July 2023; updated declarations are available upon request from TAITEC’s EU technical support office.
