Sartorius Airport MD8 Portable Airborne Microbial Sampler

Overview

The Sartorius Airport MD8 Portable Airborne Microbial Sampler is a CE-marked, ISO 14698-1 compliant instrument engineered for quantitative assessment of viable airborne microorganisms in controlled environments. It operates on the principle of isokinetic membrane filtration—drawing air through a sterile, replaceable gelatin or pre-poured Bactair™ agar membrane under precisely regulated volumetric flow. Unlike impactor-based samplers, the MD8 employs low-shear aspiration to preserve microbial viability during collection, ensuring high recovery rates of sensitive organisms such as Aspergillus, Bacillus, and Pseudomonas species. Designed for use in Grade A–D cleanrooms per EU GMP Annex 1 and ISO 14644-1 classifications, the MD8 delivers traceable, reproducible sampling data essential for environmental monitoring programs in pharmaceutical manufacturing, biotechnology R&D, hospital isolation units, public health laboratories, and food safety QA/QC facilities.

Key Features

• Battery-powered portable architecture enabling unrestricted deployment across cleanroom suites, isolators, laminar flow hoods, and field-based environmental surveys.
• Four discrete, user-selectable flow rates (30, 40, 50, and 125 L/min) with integrated thermal mass flow sensor calibrated to ±2% full-scale accuracy across 1–16 m³/h range.
• Intelligent power management system displaying real-time battery status; supports continuous operation up to 4.5 hours at 50 L/min (typical usage profile).
• Ergonomic housing constructed from medical-grade, non-porous polymer—designed for rapid wipe-down with ethanol or sporicidal agents without compromising structural integrity.
• Non-volatile memory retains last-used parameters—including flow rate, sampling duration, and language selection—even after automatic shutdown or battery depletion.
• Multi-language interface (English, French, German, Italian, Spanish) compliant with multinational facility SOPs and operator training requirements.
• Integrated calibration verification port compatible with NIST-traceable primary standards for routine in-house performance checks per ISO/IEC 17025 guidelines.

Sample Compatibility & Compliance

The Airport MD8 accepts standardized 80 mm diameter gelatin membranes or Sartorius-certified Bactair™ pre-filled agar discs (e.g., Tryptic Soy Agar, Sabouraud Dextrose Agar), eliminating manual pouring and reducing contamination risk. All consumables are gamma-irradiated and supplied with CoA documentation. The system complies with critical regulatory frameworks including EU GMP Annex 1 (2022), ISO 14698-1:2003 (Biocontamination control), ISO 14644-1:2015 (Cleanroom classification), and ASTM D6329-98 (Standard Guide for Assessing Microbial Contamination in Cleanrooms). Its design supports 21 CFR Part 11–ready data integrity when paired with validated Sartorius LabX® Environmental Monitoring software.

Software & Data Management

While the MD8 operates as a standalone instrument, it integrates seamlessly with Sartorius LabX Environmental Monitoring Suite for centralized data acquisition, audit trail generation, and electronic signature enforcement. LabX provides automated calculation of CFU/m³, trend analysis across sampling locations, and configurable alerts for out-of-specification events. All raw sampling metadata—including timestamp, flow rate, volume, operator ID, and location tag—are cryptographically signed and stored with immutable audit trails satisfying GLP/GMP and FDA 21 CFR Part 11 requirements. Export formats include CSV, PDF reports, and XML for LIMS interoperability.

Applications

• Environmental monitoring of aseptic processing lines and isolator glove ports during sterile drug manufacturing.
• Baseline qualification and periodic requalification of cleanroom classifications per ISO 14644-2.
• Investigation of microbial excursions in HVAC systems and critical utility points (e.g., compressed air, nitrogen).
• Validation of disinfection efficacy following terminal sterilization cycles or hydrogen peroxide vapor (HPV) decontamination.
• Public health surveillance in hospitals, clinics, and pandemic response field labs requiring rapid, field-deployable bioaerosol assessment.
• Microbial load profiling in food production environments—especially dairy, beverage, and ready-to-eat meal facilities governed by HACCP and FSMA requirements.

FAQ

Is the Airport MD8 suitable for ISO Class 5 (Grade A) environments?
Yes—the MD8’s low-vibration motor, laminar airflow path, and certified filter compatibility meet the stringent particle and microbiological recovery requirements for Grade A zones when operated with appropriate sampling protocols.
Can I perform on-site calibration without sending the unit to a service center?
Yes—using a NIST-traceable dry calibrator (e.g., Bioscience Instruments FlowCal™), users can execute full-range flow verification and adjustment via the built-in calibration mode.
Does the device support integration with existing LIMS or MES platforms?
Yes—via LabX middleware or direct API access, the MD8 exports structured metadata compliant with ASTM E1482 and HL7 FHIR standards for seamless ingestion into enterprise quality systems.
What is the recommended maintenance interval for the internal pump and flow sensor?
Sartorius recommends preventive maintenance every 12 months or after 1,000 operating hours, whichever occurs first—per the documented service schedule in the IQ/OQ/PQ validation package.
Are Bactair™ agar discs validated for specific pharmacopoeial methods?
Yes—TSA-based Bactair™ discs are qualified for USP , EP 2.6.12, and JP 4.06 microbial enumeration tests when used with the MD8 under validated sampling volumes and incubation conditions.
