Zhongke Aobo BX Series Portable Incubator

Overview

The Zhongke Aobo BX Series Portable Incubator is a compact, benchtop-controlled temperature chamber engineered for low-temperature biological incubation applications where space efficiency, transportability, and thermal stability are critical. Unlike conventional laboratory ovens or high-temperature drying cabinets, the BX series operates exclusively in the physiological range (5–45 °C), making it suitable for microbial culture maintenance, enzyme activity assays, cell viability studies, and short-term sample conditioning in non-sterile environments. Its design follows fundamental principles of convective heat transfer with perimeter-mounted tubular heaters and passive air circulation—ensuring predictable thermal response without forced-air fans that may disturb sensitive samples or introduce contamination risks. The unit is not intended for sterilization, lyophilization, or high-temperature drying; rather, it serves as a stable, low-power incubation platform for field-deployable labs, teaching laboratories, mobile diagnostic units, and satellite research stations requiring consistent ambient-equivalent or mildly elevated temperature control.

Key Features

• PID-based digital temperature controller with dual LED display showing setpoint and real-time chamber temperature, enabling precise manual adjustment and visual monitoring
• Programmable timer function with audible alarm output upon completion or thermal deviation beyond user-defined thresholds
• Auto-tuning capability for adaptive PID parameter optimization based on load conditions and ambient fluctuations
• Temperature offset calibration function to compensate for sensor drift or systematic measurement bias
• Over-temperature cutoff protection circuitry that deactivates heating elements if internal temperature exceeds the upper limit by >2 °C
• Seamless one-piece stainless steel inner chamber (SUS304) with radius-rounded corners for ease of cleaning and reduced microbial retention
• Perimeter-heating architecture with four-sided tubular heater placement to minimize vertical thermal gradients and improve spatial uniformity
• Magnetic gasket door seal ensuring repeatable closure force and minimal heat leakage during intermittent access
• Electrostatically powder-coated cold-rolled steel exterior for corrosion resistance and mechanical durability under routine handling
• Ergonomic top-mounted handle integrated into the lid structure, facilitating safe lifting and relocation between workstations or transport vehicles

Sample Compatibility & Compliance

The BX incubators accommodate standard microbiological vessels including Petri dishes (up to 150 mm diameter), test tubes (16–20 mm OD), multi-well plates (96-well format), and small-volume glass vials. Chamber geometry supports upright positioning of most common labware without interference from internal fixtures. Units comply with general electrical safety requirements per IEC 61010-1:2010 for laboratory equipment. While not certified to ISO 13485 or FDA 21 CFR Part 11, the BX series supports GLP-aligned documentation practices through manual logbook entries and external data logging via optional USB-connected thermocouple interfaces. It meets basic environmental operating specifications outlined in ISO 14644-1 Class 8 cleanroom-compatible usage when deployed in controlled indoor settings.

Software & Data Management

The BX series operates as a standalone hardware system with no embedded firmware update capability or native network connectivity. Temperature data logging requires external instrumentation: users may integrate calibrated Type-K thermocouples connected to third-party data acquisition systems (e.g., Keysight 34972A, NI USB-TC01) for time-stamped thermal profiling. All operational parameters—including setpoint, timer duration, and alarm status—are retained in volatile memory during power cycling but do not support non-volatile storage or audit trail generation. For regulated environments requiring electronic records, integration with validated LIMS or ELN platforms must be achieved via analog voltage output modules or RS-232/USB adapters (sold separately).

Applications

• Bacterial and fungal colony development in clinical microbiology screening workflows
• Enzyme kinetics studies requiring isothermal reaction conditions at 37 °C or ambient-adjusted temperatures
• Seed germination trials and plant tissue pre-conditioning in agricultural extension labs
• Short-term storage of temperature-sensitive reagents (e.g., restriction enzymes, antibodies) prior to assay execution
• Field-deployed quality control checks for pharmaceutical excipients or nutraceutical raw materials
• Student laboratory exercises in introductory microbiology, biochemistry, and biotechnology curricula
• Backup incubation capacity during maintenance of primary CO₂ or refrigerated incubators

FAQ

Is the BX incubator suitable for sterile cell culture?

No. It lacks HEPA filtration, humidity control, and CO₂ regulation; therefore, it is not appropriate for mammalian cell culture or aseptic techniques requiring Class II biosafety conditions.

Can the unit maintain temperature accuracy under varying ambient conditions?

Yes, within specified limits: performance validation assumes ambient temperature stability at 25 ±3 °C. Operation outside this range may affect settling time and uniformity, particularly above 30 °C ambient.

Does the incubator include calibration certification?

No factory-issued NIST-traceable calibration certificate is provided. Users are advised to perform initial verification using an independent, calibrated reference thermometer before first use.

What is the maximum permissible load volume inside the chamber?

For optimal thermal uniformity, loading should not exceed 70% of total chamber volume. Overloading impedes natural convection and increases temperature gradient magnitude.

Are replacement parts such as heaters or controllers available?

Yes—standardized tubular heaters, PID controllers, and magnetic gaskets are available as spare parts through authorized Zhongke Aobo distributors under part numbers aligned with each BX model variant.
