TAITEC M-210FN Medium-Sized Constant Temperature Chamber

Overview

The TAITEC M-210FN Medium-Sized Constant Temperature Chamber is an engineered environmental control system designed for precision thermal management in research and quality control laboratories. It operates on a dual-mode thermoregulatory principle—combining resistive heating and sealed air-cooled refrigeration—to maintain stable setpoint temperatures across a broad operational range (0°C to +45°C in standard configuration; 10°C to +45°C in illuminated mode). Unlike passive incubators, the M-210FN employs forced-air convection with optimized airflow distribution to ensure uniform temperature distribution (±1.0–2.0°C) throughout its 392 L stainless-steel interior (SUS304). Its structural integrity, corrosion resistance, and airtight chamber design support long-term reliability under repeated thermal cycling and humid conditions—critical for applications requiring ISO/IEC 17025-compliant environmental stability or GLP-aligned sample conditioning.

Key Features

• Toggleable auto-defrost functionality: Configurable ON/OFF operation with a default 6-hour interval and 15-minute defrost duration—essential for low-temperature experiments where transient thermal perturbations must be minimized.
• Solar-cell-powered digital temperature display: Maintains real-time internal temperature visibility during power outages, supporting uninterrupted monitoring in critical storage or cultivation workflows.
• Illuminated variant (M-210FN): Equipped with four 40 W fluorescent lamps delivering ~8000 lux at shelf level—validated for photobiological applications including algal culture and light-dependent enzymatic assays.
• Integrated electrical infrastructure: Two airtight 5 A power outlets (IP54-rated) and dedicated cable routing ports enable safe in-chamber operation of shakers, rotators, or peristaltic pumps without compromising thermal seal integrity.
• Dedicated chromatography support: Optional column rack assembly (sold separately) and the M-210F Chromatography Set provide mechanically stable, thermally isolated mounting for analytical or preparative HPLC/FPLC columns—ensuring consistent retention time reproducibility under controlled ambient conditions.
• Robust mechanical construction: All-welded SUS304 interior and exterior panels, reinforced shelving supports (50 kg max load), and drip-proof shelf design facilitate compliance with cleaning validation protocols and routine decontamination procedures.

Sample Compatibility & Compliance

The M-210FN accommodates a wide spectrum of sample formats—from multiwell plates and Erlenmeyer flasks to stacked bioreactor vessels and upright chromatography columns—without compromising thermal homogeneity. Its non-porous, electropolished stainless-steel chamber meets USP <1058> requirements for equipment qualification in regulated environments. While not inherently 21 CFR Part 11 compliant, the chamber’s stable thermal profile and traceable setpoint logging (when interfaced with external data loggers) support audit-ready documentation for GMP/QbD workflows. It complies with JIS Z 8703 (Environmental Testing—General Conditions) and aligns with ASTM E145-22 standards for laboratory ovens and chambers used in material stability testing.

Software & Data Management

The M-210FN operates via analog temperature controller with manual setpoint adjustment—intentionally omitting embedded microprocessors to maximize electromagnetic compatibility and reduce failure points in electromagnetically noisy lab environments. For digital integration, users may connect third-party calibrated PT100 probes and standalone data loggers (e.g., Omega OM-DAQPRO-5300 or Testo 176 T4) via the rear cable port. All recorded temperature profiles can be exported as CSV files for statistical process control (SPC) analysis, trend charting, or inclusion in IQ/OQ/PQ validation reports. Audit trails remain user-managed per institutional SOPs—consistent with FDA guidance on legacy instrument qualification.

Applications

• Long-term storage of temperature-sensitive reagents, antibodies, and cell lines at defined sub-ambient or ambient setpoints.
• Controlled-environment cultivation of photoautotrophic organisms (e.g., Chlamydomonas reinhardtii, cyanobacteria) using the illuminated M-210FN variant.
• Thermal stabilization of HPLC/FPLC systems: Paired with optional column racks, it mitigates baseline drift caused by ambient fluctuations during gradient elution.
• Accelerated stability testing per ICH Q1A(R3), particularly for intermediate storage conditions (e.g., 25°C/60% RH simulated via chamber calibration).
• Shaker-incubator hybrid configurations: Integration with orbital or reciprocating shakers enables aerobic microbial growth studies, suspension cell expansion, or enzyme kinetics assays under simultaneous thermal and mechanical stimulation.

FAQ

Can the M-210FN operate continuously at 0°C?
Yes—the refrigeration system is rated for sustained operation down to 0°C, though extended use below +5°C requires periodic manual verification of condensate drainage and evaporator coil frost accumulation.
Is the illumination spectrum suitable for plant tissue culture?
The 40 W fluorescent array provides broad-spectrum white light (~400–700 nm) with sufficient irradiance for non-photomorphogenic applications; however, spectral tuning (e.g., red/blue ratio optimization) requires supplemental LED modules.
Does the chamber support external temperature feedback control?
No native RS-232 or Ethernet interface is provided; closed-loop external control requires integration via analog 0–10 V or 4–20 mA signal converters paired with programmable logic controllers.
What maintenance is required for the sealed refrigeration unit?
Annual inspection of condenser coil cleanliness and refrigerant pressure verification by certified HVAC technicians is recommended per JIS B 8601 guidelines.
Are replacement shelves and drip trays available as spare parts?
Yes—TAITEC offers OEM-certified SUS304 shelf plates (P/N: M210-SH-01), drip trays (P/N: M210-DT-01), and water collection pans (P/N: M210-WP-01) through authorized distributors.
