Zefon Z-LITE-DMKIT230 Deluxe Air Sampling Kit

Overview

The Zefon Z-LITE-DMKIT230 Deluxe Air Sampling Kit is a CE-compliant, field-deployable indoor air quality (IAQ) and occupational hygiene sampling system engineered for precision, repeatability, and regulatory traceability. Built around the Z-Lite™ IAQ sampling pump—a compact, brushless DC motor-driven unit with integrated analog flow meter and calibrated needle valve—the kit delivers stable, user-adjustable airflow up to 30 L/min, optimized for gravimetric, microbiological, and spore-trap-based aerosol collection. Unlike fixed-flow passive samplers, this active sampling platform enables controlled volumetric sampling across variable environmental conditions (e.g., temperature gradients, static pressure differentials), ensuring compliance with standardized methods including ASTM D5755 (for mold spore analysis), ISO 16000-8 (indoor air—determination of aldehydes and ketones), and ACGIH® recommended practices for bioaerosol assessment. The system operates on 230 VAC power with low thermal drift and minimal vibration, minimizing particle resuspension during extended-duration sampling (up to 8 hours per battery-assisted operation when paired with optional external power banks).

Key Features

• Z-Lite™ IAQ pump with built-in analog flow meter and fine-tuning needle valve—enables real-time visual flow verification and precise calibration against primary standards (e.g., bubble flowmeter or electronic calibrator)
• Deluxe configuration includes 20 Air-O-Cell® cassettes—disposable, two-stage impactor-style collection devices validated for simultaneous capture of viable and non-viable airborne particles ≥0.8 µm aerodynamic diameter
• 25 Bio-Tape™ adhesive slides and 10 sterile swabs—certified for surface microbiological sampling per ISO 14698-1; compatible with direct microscopic enumeration or culture-based analysis
• Integrated biological filter (0.3 µm pore size, hydrophobic PTFE membrane)—installed upstream of pump to prevent microbial contamination of internal components and ensure operator safety during high-bio-load environments
• Rugged, injection-molded carrying case with custom-cut foam inserts—meets IATA Section II packaging requirements for transport of biological samples under UN3373 guidelines
• No firmware or embedded software—eliminates validation burden under FDA 21 CFR Part 11; all operational parameters are manually set and documented in hardcopy field logs

Sample Compatibility & Compliance

The Z-LITE-DMKIT230 supports a defined suite of Zefon-certified consumables, each traceably manufactured under ISO 9001-controlled processes. Air-O-Cell® cassettes comply with NIOSH Method 5522 for fungal spore quantification and are validated for use with light microscopy (400× magnification) and digital image analysis platforms. Bio-Tape™ slides meet ASTM E2993-15 specifications for surface bioburden recovery efficiency (≥85% for Aspergillus niger spores on stainless steel). All consumables carry lot-specific CoA documentation, including sterility assurance levels (SAL 10⁻⁶) and endotoxin testing (<0.03 EU/mL). The complete kit aligns with GLP audit requirements for environmental monitoring programs in pharmaceutical cleanrooms (ISO 14644-1 Class 5–8), hospital HVAC validation, and post-remediation clearance testing per IICRC S520.

Software & Data Management

This is a hardware-only, analog-operated sampling system—no proprietary software, cloud connectivity, or data logging is included or required. Flow rate, sampling duration, location ID, and cassette lot numbers are recorded manually on Zefon-supplied chain-of-custody forms (Form Z-AIR-01 Rev. D), which satisfy ALTA (American Industrial Hygiene Association) Field Documentation Standards. Laboratories receiving samples are provided with a standardized submission sheet indicating pump calibration date (traceable to NIST), flow verification method used onsite, and environmental conditions logged at start/end of sampling. For clients requiring electronic records, integration with LIMS systems is achieved via scanned PDF uploads of completed field forms—fully compliant with 21 CFR Part 11 when paired with organizational electronic signature policies.

Applications

• Indoor air quality investigations in schools, office buildings, and residential structures following water intrusion or HVAC complaints
• Occupational exposure assessments for mold, dust mites, pollen, and industrial bioaerosols in food processing, pharmaceutical manufacturing, and agricultural facilities
• Post-remediation verification per EPA Mold Remediation in Schools and Commercial Buildings guidance
• Surface contamination mapping in cleanroom environments using Bio-Tape™ for ISO 14644-1 particle class verification
• Baseline environmental monitoring prior to commissioning of critical infrastructure (e.g., data centers, hospitals, laboratories)

FAQ

Is the Z-LITE-DMKIT230 suitable for outdoor ambient air sampling?

No—it is specifically engineered for indoor and occupational settings where controlled flow rates (≤30 L/min) and short-duration sampling (typically 5–30 min) are required. Outdoor applications demand higher flow capacity, weatherproof enclosures, and isokinetic inlets not present in this configuration.
Can the Z-Lite™ pump be calibrated in-house?

Yes—using a NIST-traceable primary standard (e.g., dry cal gas meter or electronic flow calibrator), users may perform field calibration per Zefon Technical Bulletin TB-023. Calibration certificates must reference the specific pump serial number and date of verification.
Are Air-O-Cell® cassettes compatible with PCR-based analysis?

Yes—validated extraction protocols exist for DNA recovery from Air-O-Cell® filters using commercial kits (e.g., QIAGEN DNeasy PowerSoil Pro); however, users must validate extraction efficiency for their target organisms and downstream assay.
Does the kit include pump calibration documentation?

Each Z-Lite™ pump ships with a factory calibration certificate (valid for 12 months), listing initial flow accuracy ±5% of setpoint at 23°C and 1 atm. Recalibration is recommended annually or after 200 operating hours.
What is the maximum continuous runtime on AC power?

Unlimited—when connected to stable 230 VAC supply, the pump operates continuously without thermal shutdown. Duty cycle limitations apply only when using optional portable battery packs (not included in DMKIT230).
