BOXUN HPX-9272MBE Electrically Heated Constant-Temperature Incubator

Overview

The BOXUN HPX-9272MBE 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 principles with forced-air convection—enabled by a high-efficiency imported motor and optimized airflow ducting—to ensure minimal thermal gradients across the chamber. Unlike humidified or CO₂-incorporated incubators, this model is purpose-built for applications requiring strictly controlled dry heat conditions, such as microbial culture maintenance, enzyme activity assays, cell line passaging at non-CO₂-dependent temperatures, and stability testing of pharmaceutical intermediates per ICH Q1A(R3) guidelines. Its microprocessor-based temperature controller delivers real-time regulation with 0.1°C resolution and maintains setpoint stability within ±0.2°C at 37°C—a performance benchmark aligned with ISO 13408-1 requirements for sterile processing equipment qualification.

Key Features

• Robust construction: Cold-rolled steel outer casing with electrostatic powder coating; mirror-finish 304 stainless steel interior chamber resistant to corrosion and routine disinfectants (e.g., 70% ethanol, 1% sodium hypochlorite)
• Precision thermal management: Digitally calibrated PID control algorithm with independent over-temperature safety cutoff (adjustable up to 70°C), preventing sample degradation during power anomalies
• Optimized air circulation: Asymmetric wind tunnel design and rear-mounted centrifugal blower ensure uniform heat distribution—verified at ±0.5°C across all shelf levels per ASTM E145-22 Annex A3 test protocol
• User-centric ergonomics: Full-view tempered glass door with magnetic silicone nanocomposite gasket (enhanced thermal resistance and seal longevity); three independently adjustable stainless steel shelves with load capacity ≥15 kg each
• Intelligent system resilience: Built-in parameter retention memory that preserves setpoints, timer values, and alarm thresholds during unexpected power loss; automatic recovery upon re-energization without manual reconfiguration
• Regulatory-ready operation: Compliant with IEC 61010-1:2010 for laboratory electrical safety; supports GLP-compliant documentation via optional RS232/USB data logging interface (firmware v2.4+)

Sample Compatibility & Compliance

The HPX-9272MBE 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—on its fully removable, autoclavable shelves. Its dry environment eliminates condensation-related contamination risks, making it suitable for applications governed by USP on environmental controls for non-sterile compounding. While not certified for GMP manufacturing use out-of-the-box, the unit meets foundational criteria for IQ/OQ validation per Annex 15 of the EU GMP Guide when paired with third-party calibration certificates (NIST-traceable RTD probes recommended). It does not support humidity control or CO₂ regulation; therefore, it is excluded from mammalian cell culture workflows requiring gas-phase modulation.

Software & Data Management

The embedded microcontroller supports standalone operation without external software dependency. All operational parameters—including current temperature, setpoint, elapsed time, remaining timer duration, and fault codes—are displayed on a high-contrast LED interface. For traceability, optional firmware upgrade enables timestamped event logging (power-on, setpoint change, alarm trigger, door open/close) stored internally for up to 30 days. When connected via USB-to-serial adapter, raw data exports as CSV-compatible ASCII streams compatible with LabArchives ELN, MATLAB, or custom Python-based analysis pipelines. Audit trail functionality satisfies FDA 21 CFR Part 11 requirements when deployed with validated electronic signature modules and role-based access controls.

Applications

• Bacterial and fungal culture incubation (e.g., E. coli, S. aureus, A. niger) per CLSI M02-A12 standards
• Enzyme kinetics studies requiring precise thermal ramping (e.g., Taq polymerase activation, restriction digest optimization)
• Seed germination and plant tissue culture pre-incubation under defined thermal regimes (ISTA Rule 5)
• Stability testing of diagnostic reagents, vaccines, and excipients under accelerated conditions (ICH Q1A–Q1E)
• Quality control of industrial biocatalysts and fermentation starters in food & beverage QA labs
• Pre-warming of media, buffers, and consumables prior to aseptic processing

FAQ

Is the HPX-9272MBE suitable for CO₂-dependent cell culture?
No. This is a dry, ambient-air incubator without CO₂ monitoring, humidification, or gas mixing capabilities.
Can the internal shelves be removed for cleaning or sterilization?
Yes. All three stainless steel shelves are fully detachable and withstand autoclaving at 121°C for 20 minutes.
Does the unit include NIST-traceable calibration documentation?
Factory calibration is performed using ISO/IEC 17025-accredited reference standards; full calibration certificate is available as an optional add-on at time of order.
What safety certifications does the incubator hold?
It complies with IEC 61010-1:2010 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and meets CE marking requirements under the Low Voltage Directive 2014/35/EU.
How is temperature uniformity verified across the working volume?
Uniformity is validated per ASTM E145-22 using nine-point thermocouple mapping (center + eight corners) at 37°C and 55°C, with results documented in the出厂检验报告 (Factory Test Report) provided with each unit.
