BOXUN BSC-400 Temperature and Humidity Controlled Incubator

Overview

The BOXUN BSC-400 Temperature and Humidity Controlled Incubator is an engineered environmental simulation system designed for precise, long-term maintenance of temperature and relative humidity conditions in life science laboratories and industrial quality assurance settings. It operates on a dual-control principle: air-jacketed heating ensures rapid thermal response and stability, while a high-efficiency compressor-based refrigeration system enables active cooling across the full operational range. Humidification is achieved via a finned electric heating tube integrated with a large-capacity, user-accessible reservoir—eliminating frequent refills and minimizing operational interruption. The chamber’s microprocessor-controlled environment supports ISO 14644 cleanroom-compatible applications, USP stability testing protocols, and ICH Q1–Q5 guideline-compliant storage conditions for pharmaceutical intermediates and finished dosage forms.

Key Features

• Air-jacketed heating architecture with independent compressor-driven cooling—enabling simultaneous, non-interfering control of temperature and humidity
• Integrated large-volume water reservoir with automatic level monitoring and low-water alarm; humidification system utilizes corrosion-resistant finned heating elements for uniform vapor distribution
• Intelligent microcontroller with backlit LCD interface displaying real-time temperature, humidity, elapsed time, and programmable cycle status
• Optimized airflow design featuring centrifugal blower and proprietary multi-directional ducting—ensuring ±1 °C temperature uniformity at 37 °C (per ASTM E171 validation methodology)
• Stainless steel mirror-finish interior (304 grade), cold-rolled steel exterior with epoxy electrostatic coating, and four adjustable stainless steel shelves with load rating ≥15 kg per shelf
• RS-485 serial interface compliant with Modbus RTU protocol for integration into LIMS or centralized monitoring systems; optional data logging via external recorder or PC software
• Power-loss recovery function with non-volatile memory preserving setpoints, program sequences, and alarm history; auto-resume operation upon power restoration
• Mechanical door lock standard; optional GPRS-based SMS alert module for out-of-range condition notification (temperature/humidity deviation, door open, power failure)

Sample Compatibility & Compliance

The BSC-400 accommodates a broad spectrum of sample types including cell culture flasks (T25–T225), Petri dishes, stability test chambers (ICH trays), textile swatches, polymer packaging specimens, and accelerated aging test units. Its sealed chamber design meets Class II biological safety requirements for non-sterile environmental incubation. The unit complies with GB/T 2423.3–2016 (equivalent to IEC 60068-2-78) for damp heat testing, and supports GLP/GMP documentation workflows through configurable audit trails, user access levels, and electronic signature-ready event logs when paired with validated third-party software. Humidity sensor calibration traceability aligns with NIST-traceable standards via optional annual service certification.

Software & Data Management

The embedded controller supports up to 30 programmable segments per cycle, with 99 repeat cycles—ideal for simulating diurnal temperature/humidity profiles or multi-stage stability protocols. All parameters—including setpoints, deviations, alarm triggers, and runtime statistics—are stored in internal flash memory with timestamping. The RS-485 interface enables bidirectional communication using industry-standard Modbus registers, allowing seamless integration with LabVIEW, MATLAB, or custom SCADA platforms. Optional printer module provides real-time strip-chart recording of temperature and humidity trends; CSV export capability supports statistical process control (SPC) analysis per ISO 13485 Annex A.

Applications

• Pharmaceutical stability studies (long-term, accelerated, intermediate conditions per ICH Q1A–Q1E)
• Biological reagent and vaccine storage validation under controlled humidity
• Polymer and composite material aging tests per ASTM D3045 and ISO 4892-2
• Textile moisture regain and dimensional stability evaluation (AATCC Test Method 20A)
• Food product shelf-life modeling under variable RH conditions (e.g., cracker crispness, chocolate bloom inhibition)
• Electronics component preconditioning prior to thermal cycling (JEDEC JESD22-A110)
• Microbial growth kinetics under defined hygrothermal stress (ISO 21527-1 for yeast/mold enumeration)

FAQ

What is the maximum allowable ambient operating temperature for the BSC-400?

The unit is rated for continuous operation in ambient environments up to 32 °C with ≤70 %RH, as specified in its technical datasheet.
Does the BSC-400 support 21 CFR Part 11 compliance?

Out-of-the-box, it provides audit trail-ready event logging; full Part 11 compliance requires deployment with validated third-party software and administrative controls.
Can the internal humidity be maintained below 50 %RH?

No—the humidification system is designed for 50–90 %RH; dehumidification is not implemented; users requiring sub-50 %RH must employ external desiccant systems.
Is the stainless steel interior electropolished?

The inner chamber uses standard mirror-finish 304 stainless steel; electropolishing is available as a custom-order option.
How often does the humidification system require maintenance?

Under normal use (60 %RH, 25 °C), the integrated reservoir supports >72 hours of continuous operation; quarterly descaling of the heating tube is recommended using 5 % citric acid solution.
