Boxun BXM-100M Vertical Steam Sterilizer

Overview

The Boxun BXM-100M Vertical Steam Sterilizer is an ISO-compliant, Class B vacuum-assisted steam sterilization system engineered for routine and validation-critical applications in clinical laboratories, pharmaceutical QC facilities, biomedical research centers, and academic institutions. It operates on the fundamental principle of saturated steam under controlled pressure and temperature to achieve microbial inactivation—including spores—via protein denaturation and nucleic acid disruption. Designed to meet EN 13060:2014 requirements for small steam sterilizers and aligned with key aspects of ISO 17665-1 (sterilization of health care products — moist heat), the BXM-100M delivers reproducible lethality (F₀) values across its 100 L chamber volume. Its vertical orientation optimizes floor space utilization while maintaining full accessibility for loading/unloading standard autoclave-compatible trays, glassware, and wrapped instruments. The unit integrates a dual-pressure safety architecture—mechanical overpressure lockout and electronic pressure interlock—to ensure compliance with IEC 61010-1 for laboratory equipment safety.

Key Features

• Intelligent microprocessor-based control system with 7-inch capacitive touch LCD interface supporting multilingual UI (English default), real-time parameter display, and intuitive navigation.
• 16 programmable user-defined cycles—each configurable for sterilization, drying, melting, or holding phases—with independent time/temperature setpoints and automatic phase sequencing.
• Dual independent water supply channels: one for deionized/purified water and another for municipal tap water—both equipped with level sensors and auto-refill logic to prevent dry-heating events.
• Integrated C.W.S. (Condensate Water Salvage) system recaptures and reuses sterilization condensate for pre-vacuum humidification and jacket heating, reducing total water consumption by up to 35% versus conventional systems.
• W.P.S. (Waste Purification System) employs multi-stage filtration—including activated carbon and hydrophobic membrane stages—to remove particulates, volatile organics, and bioaerosols from exhaust vapor prior to ambient release, supporting lab ventilation compliance.
• SUS304 stainless steel chamber and four-tier removable baskets provide corrosion resistance against repeated exposure to steam, cleaning agents, and biological residues; surface finish meets ASME BPE sanitary standards.
• Active forced-air cooling via high-efficiency axial fan reduces post-cycle cooldown time by ≥40% compared to passive methods—critical for throughput-sensitive environments such as hospital central sterile supply departments (CSSD).
• Standard single-point thermocouple probe enables real-time monitoring of load temperature during sterilization; optional wireless temperature sensors (validated to ±0.25°C at 121°C) support IQ/OQ/PQ documentation per FDA 21 CFR Part 11 and EU Annex 15 guidelines.

Sample Compatibility & Compliance

The BXM-100M accommodates a broad range of sterilizable loads: porous materials (e.g., gauze, linen packs), hollow devices (e.g., pipette tips, tubing), solid instruments (e.g., forceps, scalpels), and liquid media (in vented containers). Its pulse vacuum system achieves ≥99.5% air removal efficiency, enabling uniform steam penetration into complex geometries and ensuring compliance with EN 285:2015 for large sterilizers and EN 13060 for tabletop units. All operational logs—including cycle start/end timestamps, pressure/temperature profiles, alarm history, and user authentication—are timestamped, non-erasable, and exportable via USB to CSV or PDF formats. Data integrity conforms to ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) and supports audit readiness for GLP, GMP, and CAP-accredited labs.

Software & Data Management

Cycle data is stored onboard in non-volatile memory (≥10,000 cycles retained) with automatic overwrite protection for critical validation runs. Export functionality supports USB 2.0 mass storage devices; no proprietary drivers required. Optional thermal printer modules (Epson or domestic thermal ribbon models) generate hard-copy records with embedded cycle ID, operator ID, F₀ calculation, and pass/fail status—fully traceable and suitable for regulatory submissions. Firmware updates are performed via secure USB import with SHA-256 signature verification. Audit trail configuration includes mandatory user login, role-based access control (admin/operator), and change logging for all parameter modifications.

Applications

This sterilizer serves core functions across regulated and research settings: terminal sterilization of surgical kits and reusable labware in university core facilities; depyrogenation of glass vials and stoppers in biopharma pilot lines; preparation of agar plates and buffered solutions in microbiology teaching labs; decontamination of biohazardous waste prior to disposal per WHO biosafety guidelines; and validation of sterilization protocols using biological indicators (e.g., Geobacillus stearothermophilus spore strips). Its precise dwell-time control and low residual moisture (<1%) make it especially suitable for moisture-sensitive polymers and electronics-embedded medical devices requiring clean, dry post-sterilization handling.

FAQ

Does the BXM-100M support vacuum-assisted air removal?
Yes—it features a programmable pulse vacuum system (2–99 cycles) to evacuate air from porous and lumened loads prior to steam injection.
What validation support is available for regulatory audits?
Factory-calibrated temperature and pressure sensors include NIST-traceable certificates; optional wireless probes come with 3-point calibration reports (0°C, 60°C, 121°C) and software for generating IQ/OQ reports compliant with ISO 13485 and FDA 21 CFR Part 11.
Can the unit operate without a floor drain?
Yes—optional wastewater collection tank (WET-100) captures treated effluent for manual disposal where plumbing infrastructure is unavailable.
Is remote operation supported?
An optional IR remote control enables hands-free door actuation and emergency stop; Ethernet/Wi-Fi connectivity is not natively supported but may be added via third-party industrial gateways.
What maintenance intervals are recommended?
Daily: chamber wipe-down and door gasket inspection; quarterly: vacuum pump oil change and filter replacement; annually: full pressure vessel inspection and sensor recalibration by authorized service technician.
