Overview
The BOXUN BXH-130G is a precision forced-air convection oven engineered for laboratory-grade thermal processing applications requiring high temperature stability, uniform heat distribution, and operational reliability. Unlike basic gravity convection ovens, the BXH-130G integrates active air circulation via a multi-stage variable-speed fan and motorized air damper—enabling precise control over airflow dynamics within the chamber. This architecture supports consistent thermal profiles across the full 129 L working volume, critical for applications governed by pharmacopeial standards such as USP (Sterile Processing), EP 2.6.1 (Dry Heat Sterilization), and ISO 17025-accredited drying protocols. The oven operates across a calibrated range from ambient +2°C to 300°C, with temperature fluctuation maintained at ±0.3°C (at 150°C) and uniformity of ±1.9°C (at 150°C), verified per ASTM E2203–21 Annex A2 methodology. Its stainless steel (SUS304) interior, rounded internal corners, and tool-free removable shelving support rapid decontamination and compliance with GLP/GMP cleaning validation requirements.
Key Features
- Intelligent BRIGHT I control system with auto-compensation logic—dynamically adjusts PID parameters in response to ambient temperature drift and load variance.
- Backlit capacitive touch panel with real-time dual-display of setpoint/actual temperature, fan speed stage, timer status, and system diagnostics.
- Programmable 10-segment × 100-cycle profile capability, supporting complex thermal ramps, holds, and cooldown sequences for method-driven workflows.
- Dual independent overtemperature protection: primary sensor-based cut-off and secondary mechanical thermal limiter—fully compliant with IEC 61010-1 safety requirements for unattended operation.
- Motorized adjustable air damper and six-step fan speed control enable optimization of air exchange rate for dust-sensitive samples (e.g., lyophilized powders, API intermediates) or rapid equilibration during sterilization cycles.
- Preheated air inlet design directs thermally homogenized air directly into the chamber—reducing thermal lag and improving spatial uniformity per ISO 15504-2 test criteria.
- Two-point locking door mechanism with dual compression gasket ensures >95% seal integrity under thermal cycling; validated for sustained operation at 250°C without leakage.
Sample Compatibility & Compliance
The BXH-130G accommodates a broad spectrum of sample formats—including Petri dishes, weighing boats, glass vials, stainless steel trays, and borosilicate glassware—up to 25 kg per shelf. Its stainless steel chamber and smooth-welded seams prevent particle shedding and meet ISO 14644-1 Class 8 cleanroom compatibility when operated in filtered-air mode (standard inlet/outlet particulate filters included). The unit satisfies key regulatory prerequisites for pharmaceutical and biotech labs: it supports dry-heat depyrogenation per USP , residual solvent removal per ICH Q5C, moisture content determination per AOAC 950.46, and equipment qualification per ASTM E2500–22. Optional FDA 21 CFR Part 11–compliant monitoring software provides electronic audit trails, user access controls, and signature-enabled report generation—fully traceable for regulatory inspections.
Software & Data Management
Equipped with standard RS-485 communication (Modbus RTU protocol), the BXH-130G integrates seamlessly into centralized lab infrastructure. The optional FDA Edition monitoring software delivers real-time remote supervision, automated calibration log archiving, deviation alerting, and PDF report export with digital signatures. GMP Edition extends functionality with role-based permissions, electronic batch records, and change control tracking aligned with Annex 11 expectations. All data—including temperature logs, program execution history, and alarm events—are timestamped, non-erasable, and stored locally on embedded flash memory (16 GB) with optional cloud backup via Ethernet gateway (not included). Printer interfaces support both domestic thermal and Epson-compatible units for hard-copy SOP adherence.
Applications
- Pharmaceutical: Dry-heat sterilization of glassware and stainless steel components; endotoxin removal from pyrogen-sensitive devices; moisture loss testing per USP .
- Academic & Industrial Research: Polymer curing, catalyst activation, ash content determination (ASTM D3174), and gravimetric analysis of volatile residues.
- Food & Agriculture: Moisture content quantification (AOAC 930.15), fat extraction pre-drying, and mycotoxin stability studies.
- Materials Science: Pre-baking of ceramic green bodies, binder burnout in powder metallurgy, and thermal aging of composites.
- Quality Control Labs: Stability-indicating assay preparation, reference standard conditioning, and environmental stress screening per IEC 60068-2-2.
FAQ
What is the maximum operating temperature and its certified accuracy?
The BXH-130G is rated for continuous operation up to 300°C. Temperature accuracy is ±0.5°C (full scale) when calibrated against NIST-traceable reference probes per ISO/IEC 17025 procedures.
Does the oven support IQ/OQ/PQ documentation packages?
Yes—qualified installation, operational, and performance qualification templates are provided with purchase. Optional third-party validation support is available through BOXUN’s global partner network.
Can the unit be integrated into a LIMS or MES environment?
Via RS-485 Modbus RTU or optional Ethernet-to-Modbus gateway, the oven transmits real-time temperature, status flags, and event logs to enterprise systems compatible with ASTM E1384 or HL7 messaging standards.
Is the chamber pressure-rated for inert gas purging?
No—the BXH-130G is not designed for pressurized or vacuum operation. For nitrogen-purged drying, external gas manifold integration with flow-controlled inlet/outlet ports is required and must be validated separately.
What maintenance intervals are recommended for long-term reliability?
Fan motor lubrication every 12 months; gasket inspection and replacement every 24 months; annual verification of thermal uniformity and controller calibration using accredited metrology services.
