BOXUN BPX-162 Electrically Heated Constant-Temperature Incubator

Overview

The BOXUN BPX-162 Electrically Heated Constant-Temperature Incubator is a precision-engineered dry incubation system designed for stable, reproducible thermal environments in life science laboratories. It operates on resistive heating with forced-air convection, delivering uniform temperature distribution across its 148 L stainless-steel chamber without humidity control—making it ideal for applications requiring strictly anhydrous or low-moisture conditions, such as bacterial culture maintenance, enzyme activity assays, cell line passaging at sub-humid conditions, and stability testing of reagents or pharmaceutical intermediates. Its microprocessor-based PID temperature controller ensures high repeatability and minimal thermal drift, with real-time monitoring via a backlit LCD interface. The unit complies with general laboratory safety standards for Class II electrical equipment (IEC 61010-1), and its structural design supports long-term operation under GLP-aligned workflows where environmental traceability and operational continuity are critical.

Key Features

• Stainless-steel mirror-finish interior chamber (550 × 490 × 550 mm) with three removable, height-adjustable shelves for flexible sample loading and cleaning accessibility
• Electrostatically coated cold-rolled steel exterior housing for mechanical durability and corrosion resistance
• High-efficiency axial fan with imported motor and optimized air duct geometry to achieve ±0.5°C temperature uniformity (measured per ISO 15272:2015 Annex B at 37°C)
• Intelligent airflow modulation: fan speed automatically adjusts based on setpoint deviation and door-opening events to minimize thermal recovery time (≤20 min from ambient to 37°C)
• Large-view tempered glass observation window with nano-composite magnetic door seal, providing enhanced thermal insulation and visual monitoring without compromising chamber integrity
• RS-485 serial interface supporting Modbus RTU protocol for integration into centralized lab monitoring systems or third-party data loggers
• 10-segment × 100-cycle programmable profile function enabling complex thermal ramp/soak sequences for method development and validation studies
• Non-volatile memory retention preserving all user-defined parameters—including setpoints, timers, alarms, and program steps—during power interruption or unexpected shutdown

Sample Compatibility & Compliance

The BPX-162 accommodates standard microbiological vessels including Petri dishes (up to 150 mm), test tubes (16 × 150 mm), flasks (up to 2 L), and multi-well plates. Its dry incubation architecture excludes condensation-related contamination risks, making it suitable for cultures sensitive to moisture-induced variability (e.g., Bacillus subtilis, Aspergillus niger). While not certified for medical device sterilization or ISO 13485 manufacturing, the incubator meets functional requirements referenced in USP (bacterial endotoxin testing environment control), CLSI M22-A3 (microbiological incubator performance criteria), and ASTM E171 (standard specifications for environmental chambers). It is compatible with IQ/OQ documentation templates and supports audit-ready operation when paired with optional GPRS alarm modules or external print-loggers.

Software & Data Management

The BPX-162 does not include embedded PC software but provides hardware-level interoperability through its RS-485 port. Users may deploy validated third-party SCADA platforms (e.g., LabVIEW, Ignition, or custom Python-based daemons using PySerial) to acquire real-time temperature readings, event logs (door open/close, overtemperature alerts), and program status. Optional accessories—including thermal printer modules (supporting time-stamped curve output) and GPRS-enabled SMS alert transmitters—extend compliance readiness for 21 CFR Part 11 environments when combined with appropriate electronic signature controls and audit trail configurations. All firmware updates are delivered via physical USB programmer; no cloud connectivity or remote firmware update capability is implemented.

Applications

• Maintenance of mesophilic bacterial and fungal stock cultures (e.g., E. coli, S. aureus, Candida albicans) at standardized temperatures (30–37°C)
• Enzyme kinetics studies requiring precise thermal control without vapor-phase interference
• Accelerated stability testing of diagnostic reagents, lyophilized proteins, and small-molecule APIs under dry storage protocols
• Pre-incubation of samples prior to PCR setup or ELISA plate coating to minimize thermal shock effects
• Environmental simulation for material compatibility testing (e.g., polymer degradation, adhesive curing)
• Teaching laboratories requiring robust, entry-level incubation platforms with transparent operational feedback and configurable timing logic

FAQ

Is the BPX-162 suitable for CO₂-dependent cell culture?

No. This is a dry, electrically heated convection incubator with no CO₂ regulation, humidity control, or gas-tight sealing. It is intended for non-CO₂-requiring organisms and biochemical assays.
Does the unit support validation documentation (IQ/OQ)?

Yes—its stable thermal performance, programmable profiles, RS-485 data export, and parameter retention align with common IQ/OQ protocol elements. Customers typically perform sensor mapping per ISO 15272 and generate calibration certificates using external NIST-traceable thermistors.
Can the incubator be operated continuously for extended periods?

Yes. Designed for 24/7 operation, the BPX-162 features thermal cut-off protection, reinforced insulation, and a duty-cycle-optimized heating element rated for >20,000 hours of continuous service under nominal load conditions.
What is the maximum ambient temperature for safe operation?

The unit is rated for ambient environments up to 32°C. Operation above this temperature may extend stabilization time and reduce long-term thermal accuracy; installation in air-conditioned labs is recommended for optimal performance.
Are spare parts and service manuals available internationally?

BOXUN provides English-language technical documentation, schematic diagrams, and consumables (door seals, shelf supports, fuses) through authorized regional distributors. Firmware binaries and service diagnostics tools are distributed under NDA upon request for qualified field engineers.
