WIGGENS VF203B Portable Vacuum Filtration Kit

Overview

The WIGGENS VF203B Portable Vacuum Filtration Kit is an engineered solution for rapid, field-deployable or benchtop vacuum-assisted liquid filtration in regulated and research laboratory environments. Designed around the Couette-type diaphragm vacuum pump principle, the system generates stable sub-atmospheric pressure (≥150 mbar) to drive controlled fluid passage through microporous media—enabling precise particulate capture, microbial retention, or solvent clarification without thermal degradation. Its compact architecture integrates a corrosion-resistant borosilicate glass VF2 filtration funnel assembly with a quick-drain waste bottle and magnetic base mount, ensuring mechanical stability during operation and minimizing risk of tipping during high-volume or unattended filtration cycles. The kit meets fundamental functional requirements for gravimetric suspended solids (TSS) analysis per ISO 5667-12 and ASTM D5907, and supports membrane-based microbiological enumeration protocols aligned with ISO 9308-1 (E. coli), ISO 6222 (total coliforms), and USP .

Key Features

• Integrated magnetic base station for secure, vibration-damped positioning on stainless steel or ferromagnetic work surfaces—critical for uninterrupted filtration during transport or mobile lab deployment.
• Borosilicate glass VF2 filtration funnel set rated to Class A volumetric accuracy (DIN EN ISO 1042), resistant to thermal shock and chemical attack from organic solvents, acids, and bases commonly used in HPLC mobile phase preparation or AA sample digestion.
• Hydrophobic 0.2 µm PTFE vent filter prevents backstreaming of moisture or aerosols into the vacuum pump head—extending service life and maintaining consistent vacuum performance across repeated sterilization cycles.
• Modular silicone tubing (included) complies with USP Class VI and FDA 21 CFR 177.2300 specifications, ensuring extractables-free operation during pharmaceutical or clinical sample processing.
• Dragon100 Bunsen burner enables on-site flame sterilization of filtration apparatus prior to environmental or food microbiology assays—supporting GLP-compliant workflow integrity.
• Low-noise (50 dB(A)) operation allows continuous use in shared analytical laboratories without acoustic interference to adjacent instrumentation such as balances or autosamplers.

Sample Compatibility & Compliance

The VF203B accommodates standard 47 mm and 90 mm diameter membrane filters—including mixed cellulose ester (MCE), polycarbonate (PC), polyethersulfone (PES), and the supplied 1 µm glass fiber pre-filters—across aqueous, alcoholic, and mildly acidic matrices. It is routinely validated for use in drinking water analysis (EPA Method 1603), beverage turbidity screening (AOAC 971.25), and pharmaceutical parenteral filter integrity testing (ASTM F838). All glass components conform to DIN 12331 and ISO 3585 standards for laboratory glassware. The vacuum pump’s electrical design complies with IEC 61010-1 for safety in laboratory equipment, and the full system supports audit-ready documentation under GMP Annex 11 and FDA 21 CFR Part 11 when paired with compliant electronic logbooks.

Software & Data Management

As a manually operated mechanical system, the VF203B does not incorporate embedded firmware or digital control interfaces. However, its operational parameters—including vacuum level (monitored via external analog gauge), filtration duration, and filter type—are fully traceable within laboratory information management systems (LIMS) when recorded using standardized SOP templates. The kit is compatible with digital vacuum gauges (e.g., MKS Baratron series) and time-stamped video documentation workflows required for ISO/IEC 17025 accreditation. All supplied consumables bear batch-specific traceability codes for raw material verification and expiry tracking.

Applications

• Microbiological membrane filtration for total viable count (TVC), coliform, and pathogen enumeration in water, dairy, and beverage samples.
• Gravimetric determination of total suspended solids (TSS) and settleable solids in wastewater and surface water per ISO 11923.
• Pre-filtration of HPLC mobile phases, GC sample extracts, and atomic absorption standards to eliminate particulates >1 µm.
• Solvent purification for trace-metal analysis, including acid digestion blanks and calibration stock preparation.
• Field-based environmental monitoring where mains-powered vacuum manifolds are impractical—enabled by its 7.1 kg portable mass and universal AC input.

FAQ

Is the VF203B suitable for sterile filtration of culture media?
Yes—when used with 0.22 µm sterilizing-grade membranes (not included) and flame-sterilized via the integrated Dragon100 burner, it satisfies ISO 13408-1 requirements for aseptic processing validation.
Can the vacuum pump be operated continuously for >8 hours?
The diaphragm pump is rated for intermittent duty (max. 60 min ON / 30 min OFF); extended operation requires thermal monitoring and ambient temperature ≤25 °C to maintain ≥150 mbar vacuum stability.
Does the kit include calibration certificates for the glassware?
Class A volumetric certification is available upon request (additional lead time and fee apply); standard delivery includes DIN-compliant dimensional conformity without individual calibration documentation.
What maintenance is required for long-term reliability?
Biannual inspection of diaphragm integrity, replacement of PTFE vent filter after 50 sterilization cycles, and silicone tubing replacement every 12 months under continuous use.
Is the system compatible with vacuum controllers for automated pressure regulation?
Yes—the 9 mm hose barb interface supports integration with third-party PID-controlled vacuum regulators (e.g., Vacuubrand VRV series) for programmable stepwise filtration profiles.
