BOXUN BXM-60FI Vertical Steam Sterilizer

Overview

The BOXUN BXM-60FI Vertical Steam Sterilizer is a CE-compliant, Class B vacuum-assisted steam sterilization system engineered for laboratories, clinical research facilities, and pharmaceutical QC environments requiring validated, repeatable terminal sterilization of heat-stable materials. It operates on the fundamental principle of saturated steam under pressure—leveraging the lethal effect of moist heat at temperatures exceeding 121 °C (typically 121–135 °C) to irreversibly denature microbial proteins and nucleic acids. Unlike gravity-displacement sterilizers, the BXM-60FI integrates programmable positive-pressure pulsing and vacuum drying cycles, enabling full air removal from porous loads (e.g., wrapped instruments, textile packs, large-volume culture media) and eliminating cold spots that compromise sterility assurance. Its 60 L chamber accommodates standard ISO/EN 285-compliant load configurations—including up to two 370 × 245 mm trays—and supports F₀-based cycle validation when paired with optional probe sensors.

Key Features

• PMMA II microprocessor control system with 7-inch capacitive touchscreen interface, displaying real-time temperature, pressure, time, phase status, and graphical cycle progress
• Eight pre-programmed cycles (sterilize, dry, melt, hold, liquid, slow exhaust, fast exhaust, custom) plus six user-definable protocols with adjustable parameters
• 6-stage positive-pressure pulse sequence for complete air removal—critical for achieving >99.999% microbial log reduction in dense or wrapped loads per ISO 17665-1
• Vacuum-assisted drying mode (80–130 °C) with selectable vacuum level and duration, minimizing post-cycle handling and preventing recontamination of sterile instruments or textiles
• Three-tier access control (Engineer, Administrator, Operator) supporting audit-ready role-based permissions and password protection
• Integrated rapid cooling system combining forced-air convection, secondary water cooling, and condensate management—reducing chamber cooldown time by up to 40% versus passive cooling
• Comprehensive safety architecture: independent electronic overpressure cutoff, mechanical pressure lock, lid self-check interlock, dry-run protection, ground-fault circuit interruption, thermal cutout, and real-time fault diagnostics with error code logging

Sample Compatibility & Compliance

The BXM-60FI is validated for sterilizing a broad range of laboratory and biomedical materials, including but not limited to: autoclavable glassware (flasks, pipettes, Petri dishes), stainless-steel surgical instruments, cotton gauze and linen packs, agar and broth media (in vented containers), and regulated biohazard waste (in autoclave bags). Its chamber geometry and steam distribution design conform to EN 285:2015 requirements for large sterilizers, while its temperature uniformity (±0.3 °C) and stability (<+1 °C fluctuation) meet ISO 17665-1 Annex A validation criteria. Optional accessories—including a 0.2 µm sterilizing-grade exhaust filter, calibrated PT100 sample temperature probes for F₀ calculation, and a GLP/GMP-compliant thermal printer with USB storage—enable full compliance with FDA 21 CFR Part 11, EU Annex 1, and WHO TRS 992 Annex 5 documentation standards.

Software & Data Management

Cycle execution, parameter logging, and event history are managed via the embedded PMMA II OS, which records timestamped temperature, pressure, and phase data at 1-second intervals. All logs are exportable via USB to CSV or PDF formats. The optional thermal printer provides hard-copy output of cycle ID, start/end times, peak temperature, dwell time, F₀ value (when probe-equipped), and real-time temperature curve—fully traceable for internal audits or regulatory submissions. System firmware supports secure remote diagnostics via RS-485 ports (two standard), and the G1/2A validation port enables integration with third-party data loggers for IQ/OQ/PQ verification per VDI/VDE 2646 and ISO 13485 requirements.

Applications

• Terminal sterilization of microbiological growth media in academic and industrial labs
• Pre-sterilization of reusable surgical tools and implantable device components in R&D cleanrooms
• Decontamination of Category B biological waste prior to disposal (per WHO Biosafety Manual guidelines)
• Moist-heat validation studies supporting ISO 11134 and ISO 11140-1 bioburden reduction claims
• Process development for steam sterilization of lyophilized product containers and primary packaging
• Calibration and qualification of temperature sensors and pressure transducers using reference-grade validation ports

FAQ

What sterilization standards does the BXM-60FI comply with?
It meets EN 285:2015 for large steam sterilizers and supports validation per ISO 17665-1, ISO 11134, and FDA 21 CFR Part 11 when configured with optional probes and printer.
Can it sterilize liquids safely without boil-over?
Yes—the “Liquid” program employs slow heating and controlled exhaust to prevent violent boiling; optional pressure-controlled exhaust further minimizes container rupture risk.
Is altitude compensation supported?
Yes—the built-in boiling point adjustment function allows manual input of local atmospheric pressure or elevation to ensure accurate temperature setpoint delivery at high-altitude sites.
What safety certifications does the unit carry?
It carries CE marking per Machinery Directive 2006/42/EC and Pressure Equipment Directive 2014/68/EU; electrical safety complies with IEC 61010-1.
How is maintenance and service performed?
All critical components—including door seal, safety valves, and steam generator—are accessible without specialized tools; service logs and calibration records are retained internally and exportable via USB.
