BOXUN BXM-85BE Vertical Steam Autoclave

Overview

The BOXUN BXM-85BE Vertical Steam Autoclave is a CE-compliant, Class B (EN 13060) laboratory-grade steam sterilizer engineered for precision, safety, and operational consistency in demanding microbiological, pharmaceutical, and clinical research environments. It operates on saturated steam under pressure—principally leveraging moist heat sterilization kinetics governed by the F₀ principle—to achieve a minimum SAL (Sterility Assurance Level) of 10⁻⁶ for wrapped and unwrapped instruments, culture media, liquids, and porous loads. Its vertical configuration optimizes floor space utilization while maintaining full compliance with ISO 17665-1 (sterilization of health care products — Moist heat), ASTM F1055 (standard specification for steam sterilizers), and relevant national medical device regulatory frameworks. The unit integrates dual-sensor temperature monitoring, real-time pressure feedback control, and a validated chamber geometry ensuring uniform steam penetration across all load configurations.

Key Features

• Intelligent BRIGHT I Control System: Adaptive algorithm compensates for ambient temperature and humidity fluctuations, dynamically adjusting cycle parameters to maintain thermal stability without manual recalibration.
• 10.1-inch HD Color Touchscreen: Ergonomically angled on the lid surface to minimize glare and optimize viewing angle; displays real-time chamber temperature, pressure, elapsed time, program status, and alarm logs simultaneously.
• Dual-Safety Lid Mechanism: Lever-actuated flip-top door with mechanical self-locking latch and redundant electronic interlock—prevents opening until pressure drops below 0.02 MPa and temperature falls below user-defined threshold (configurable down to 45 °C).
• Thermal Insulation & Surface Safety: Integrated high-molecular polymer jacket reduces external surface temperature to <45 °C during operation, meeting IEC 61010-1 touch-temperature requirements for operator protection.
• Optimized Chamber Architecture: Mirror-polished 304 stainless steel interior (Ra ≤ 0.4 µm), large-radius rolled edge at chamber mouth, and seamless welding eliminate crevices—reducing biofilm retention and simplifying cleaning validation per ISO 15883-1.
• Advanced Steam Management: Six-stage exhaust control, programmable positive-pressure pulse air removal (up to 6 cycles), and automatic post-cycle cooling reduce total cycle time by up to 35% versus conventional gravity-displacement units.
• Comprehensive Safety Architecture: Dual water-level detection (capacitive probe + dry-run thermistor), independent overpressure relief valve (0.28 MPa setpoint), thermal cutouts, ground-fault circuit interruption, and overload protection—all logged with timestamped event history.

Sample Compatibility & Compliance

The BXM-85BE accommodates standard sterilization loads including wrapped surgical kits, glassware, liquid media (with anti-boil-over mode), rubber tubing, and porous textiles. Its Class B classification confirms capability for vacuum-assisted air removal—essential for sterilizing hollow devices and lumened instruments per EN ISO 17664. The standard G1/2A validation port supports integration with third-party data loggers (e.g., Ellab, DeltaTRAK) for IQ/OQ/PQ documentation. Optional biological filter (0.22 µm hydrophobic PTFE), validation lead-through ports, and embedded thermal printer enable full traceability aligned with FDA 21 CFR Part 11 requirements for electronic records and signatures. All firmware operations retain audit trails compliant with GLP and GMP Annex 11 expectations.

Software & Data Management

The embedded controller stores ≥1,000 cycle records with full metadata: start/end timestamps, setpoints, actual temperature/pressure profiles, fault codes, and operator ID (when password-authenticated). User-modifiable programs support sample-temperature-triggered timing—critical for validating heat penetration in viscous or dense loads. Three-point temperature calibration (at 105 °C, 121 °C, and 135 °C) allows field correction against NIST-traceable reference probes. Altitude-adjustable boiling point setting ensures accurate temperature referencing at elevations up to 3,000 m. USB export (CSV format) enables offline analysis in Excel or statistical process control (SPC) platforms. Password-protected administrator mode restricts access to critical settings—including maximum pressure limits, door unlock thresholds, and calibration offsets.

Applications

This autoclave serves core sterilization workflows in academic laboratories, quality control units, hospital central sterile supply departments (CSSD), and contract manufacturing organizations (CMOs). Typical use cases include: terminal sterilization of agar plates and broth media; depyrogenation of glass vials prior to aseptic filling; pre-sterilization of bioreactor components; decontamination of BSL-2 waste; and routine instrument reprocessing in dental and veterinary clinics. Its 85 L capacity and triple-basket configuration (Ø360 × 200 mm × 3) support batch processing of up to 120 standard Petri dishes or 48 × 500 mL Erlenmeyer flasks per cycle—validated per ISO 11140-1 for chemical indicator performance.
