BOXUN BXM-60EI Vertical Steam Autoclave

Overview

The BOXUN BXM-60EI Vertical Steam Autoclave is an engineered-for-precision Class B (EN 13060-compliant) sterilization system designed for routine and validation-critical applications in academic laboratories, clinical diagnostics, pharmaceutical QC labs, and biotechnology facilities. It operates on the fundamental principle of saturated steam under controlled pressure and temperature to achieve microbial inactivation—primarily through protein denaturation and nucleic acid disruption. With a validated working range of 105–135 °C at operating pressures up to 0.22 MPa (gauge), and a maximum design pressure of 0.38 MPa, the unit meets internationally recognized sterilization efficacy benchmarks including ISO 17665-1 and EN 285 for steam sterilizers. Its 60 L cylindrical chamber (Ø400 × 635 mm) accommodates standard laboratory loads—including culture media, surgical instruments, glassware, plastic containers, and biohazard waste—while maintaining temperature uniformity within ±0.5 °C and thermal stability better than +1 °C deviation across the load.

Key Features

• PMMA-I microprocessor-based control system with capacitive touchscreen interface (≥7″), enabling real-time visualization of cycle phase, chamber pressure, jacket temperature, and dynamic status graph
• Dual-stage air removal via programmable positive-pressure pulsing (6-level adjustable pre-vacuum sequence), ensuring complete cold-air evacuation prior to sterilization—critical for porous and wrapped loads
• Post-cycle depressurization with six selectable exhaust rates to balance safety, material compatibility, and throughput efficiency
• Triple-tier user access control: Engineer (full configuration & calibration), Administrator (cycle editing & audit log management), Operator (run-only mode)
• Integrated rapid cooling system combining forced-air convection, secondary water-cooling, and condenser assembly—reducing post-cycle wait time by up to 40% versus passive cooling
• 100-hour programmable start delay with ambient temperature compensation and altitude-adjustable boiling point setting (for operation at elevations >500 m ASL)
• Full mechanical interlock with dual-safety verification: pressure-actuated door lock + lid closure self-check sensor
• Comprehensive electrical and thermal protection suite: independent electronic overpressure cutoff, dry-run detection, overtemperature shutdown, ground-fault interruption, short-circuit isolation, and thermal insulation-rated housing

Sample Compatibility & Compliance

The BXM-60EI supports sterilization of liquids (media, buffers), solids (metal instruments, glassware), porous materials (textiles, filter units), and regulated waste streams. Chamber geometry and steam distribution pathways are optimized per EN 13060 Annex A requirements for Class B autoclaves. Standard compliance includes CE marking (2014/34/EU, 2014/68/EU), GB 8599–2008 (Chinese national standard for sterilizers), and alignment with ISO 13485 quality system expectations. Optional accessories—including a 0.2 µm high-temperature steam filter, calibrated F₀-capable thermocouple probe (IEC 60751 Class A), and validation port adapters—enable full GMP/GLP process qualification per FDA 21 CFR Part 11 and EU Annex 15 guidelines.

Software & Data Management

The embedded controller logs all critical parameters (time, temperature, pressure, phase transitions) with timestamped records stored internally (≥10,000 cycles) and exportable via USB 2.0. Optional thermal printer (SPR-80 series) provides real-time hardcopy output of sterilization curves, F₀ calculations, and cycle metadata—fully traceable and compliant with ALCOA+ data integrity principles. Audit trail functionality captures user ID, action timestamp, parameter changes, and alarm events. RS-485 Modbus RTU interface enables integration into centralized lab infrastructure monitoring systems (e.g., LabVantage, Thermo Fisher SampleManager).

Applications

• Routine sterilization of microbiological growth media (e.g., agar, broth) without excessive caramelization or pH shift
• Terminal sterilization of reusable surgical tools and dental handpieces under validated cycles
• Decontamination of infectious biological waste prior to disposal or incineration
• Preparation of sterile reagents and consumables for cell culture and molecular biology workflows
• Supporting ISO/IEC 17025-accredited testing laboratories requiring documented, repeatable sterilization processes
• High-altitude facility deployment (e.g., Tibetan research stations, Andean field labs) via adaptive boiling-point calibration

FAQ

What is the maximum allowable operating temperature and pressure?
The BXM-60EI is rated for continuous operation up to 135 °C at 0.22 MPa (gauge); its pressure vessel is certified to 0.38 MPa design pressure per ASME BPVC Section VIII Division 1.
Does it support F₀-based cycle validation?
Yes—when equipped with the optional PT100-class A sample temperature probe and compatible printer, the system calculates and prints real-time F₀ values per ISO 11138-1 and USP .

Is remote monitoring or network connectivity available?
Standard RS-485 Modbus RTU allows integration with SCADA or LIMS; Ethernet or Wi-Fi modules are not built-in but may be added via third-party gateways compliant with IEC 62443-3-3.

What safety certifications does the unit hold?
CE-marked per PED 2014/68/EU and EMC Directive 2014/30/EU; conforms to GB 4793.1–2019 (safety requirements for electrical equipment) and GB 8599–2008 (performance requirements for steam sterilizers).

Can it sterilize liquid loads without boil-over?
Yes—the microprocessor implements slow-heat ramping, pressure-modulated venting, and automatic hold-phase stabilization to prevent violent boiling and container rupture during liquid cycles.
