Boxun BXM-85FI Vertical Steam Sterilizer

Overview

The Boxun BXM-85FI Vertical Steam Sterilizer is an ISO-compliant, Class B vacuum-assisted steam sterilization system engineered for laboratories, clinical facilities, and pharmaceutical R&D environments requiring reliable, repeatable, and traceable terminal sterilization of heat-stable materials. Operating on the fundamental principle of saturated steam under controlled pressure and temperature, the BXM-85FI achieves microbial inactivation—including spores of Geobacillus stearothermophilus—through moist heat denaturation of nucleic acids and proteins. Its design adheres to key international standards including EN 13060:2022 (small steam sterilizers), ISO 17665-1:2019 (sterilization by moist heat), and supports validation protocols aligned with FDA 21 CFR Part 11, EU Annex 15, and WHO TRS 977 requirements for sterilization process qualification.

Key Features

• PMMA II microcomputer control system with 7-inch capacitive touchscreen interface for real-time visualization of cycle phase, chamber pressure, jacket temperature, and dynamic status graphs
• Eight pre-programmed cycles (Sterilize, Dry, Melt, Hold, Vacuum Purge, Pre-vacuum, Liquid, Custom) plus six user-definable programs with adjustable parameters
• Positive-pressure pulsing with up to six-stage air removal sequences to ensure complete cold air evacuation—critical for dense loads such as wrapped instruments, textile packs, and large-volume liquid media
• Vacuum-assisted drying function (80–130 °C) enabling post-sterilization desiccation of metal instruments, gauze, and glassware without manual transfer—eliminating cross-contamination risk
• Three-tier access control (Engineer, Administrator, Operator) supporting role-based parameter restrictions, audit trail logging, and password-protected configuration changes
• Multi-stage pressure release (6 selectable rates) for safe, controlled depressurization following sterilization
• Integrated rapid cooling system combining forced-air convection, secondary water cooling, and condensate management—reducing lid-opening wait time by up to 40% vs. passive cooldown
• 100-hour programmable start delay and adjustable boiling point compensation for operation at altitudes up to 3,000 m above sea level
• Full thermal insulation housing with anti-scald surface finish and dual mechanical interlock + lid closure self-check safety architecture

Sample Compatibility & Compliance

The BXM-85FI accommodates a broad range of sterilizable materials: autoclavable culture media (liquid and solid), stainless-steel surgical instruments, borosilicate glassware, polymer labware (e.g., polypropylene centrifuge bottles), cotton gauze, and biohazard waste in approved autoclave bags. Its 85 L chamber (Ø400 × 725 mm) accepts two standard baskets (Ø370 × 285 mm each). The unit complies with EN 285:2015 for large steam sterilizers regarding temperature uniformity (±0.3 °C), thermal stability (<+1 °C deviation), and F₀ reproducibility. Optional accessories—including a 0.2 µm high-temp/pressure-rated exhaust filter, calibrated PT100 sample temperature probe (for F₀ calculation per ISO 11138-1), and validation port adapters—enable full IQ/OQ/PQ execution under GLP/GMP frameworks.

Software & Data Management

The embedded PMMA II OS records all operational events—including cycle initiation, phase transitions, pressure/temperature profiles, alarm triggers, and user logins—with timestamped, non-erasable entries stored locally (≥10,000-cycle capacity). Optional thermal printer (RS-485 interface) outputs validated hardcopy reports containing date/time, setpoints, actual curves, and calculated F₀ values when paired with a certified sample probe. Data export via USB flash drive supports CSV format for integration into LIMS or electronic batch record systems. All firmware updates are digitally signed and verified; audit trails meet FDA 21 CFR Part 11 requirements for electronic records and signatures.

Applications

• Terminal sterilization of microbiological growth media in academic and industrial labs
• Pre-sterilization of surgical kits and reusable diagnostic tools in outpatient clinics
• Decontamination of biohazardous waste prior to disposal in biosafety Level 2+ facilities
• Validation-grade sterilization for QC/QA labs performing compendial testing (USP , Ph. Eur. 5.1.1)
• Routine processing of glass and metal labware where post-sterilization dryness is required for immediate use
• High-altitude facility operations requiring altitude-compensated temperature control

FAQ

What sterilization standards does the BXM-85FI comply with?
It meets EN 13060:2022 (Class B small sterilizers), EN 285:2015 (large sterilizers), and ISO 17665-1:2019 for moist-heat sterilization process requirements.
Can the BXM-85FI perform F₀-based sterilization cycles?
Yes—when equipped with the optional calibrated sample temperature sensor and verification port adapter, it calculates and logs F₀ in real time per ISO 11138-1 and USP .
Is remote monitoring or network connectivity supported?
The unit provides two RS-485 ports for integration with building management systems or centralized lab monitoring platforms; Ethernet or Wi-Fi modules are not included but can be added via third-party gateways.
What safety certifications does the sterilizer hold?
It carries CE marking per Machinery Directive 2006/42/EC and Pressure Equipment Directive 2014/68/EU, with full documentation available upon request for regulatory submissions.
How is validation support provided for GMP environments?
Boxun supplies IQ/OQ protocol templates, factory acceptance test (FAT) reports, and DQ documentation packages; on-site PQ assistance is available through authorized service partners.
