Overview
The WIGGENS VF205A Vacuum Filtration Kit is an integrated, benchtop-ready system engineered for reproducible, high-efficiency liquid-phase separation in regulated laboratory environments. Designed around the principles of controlled negative-pressure filtration, the VF205A employs a brushless induction motor-driven vacuum pump to generate stable sub-atmospheric conditions (≥150 mbar ultimate vacuum), enabling rapid and consistent passage of aqueous and organic solutions through precisely rated filter media. Its architecture prioritizes operational safety and procedural fidelity—particularly critical in applications governed by standardized methods such as ISO 7899-2 (microbiological analysis of water), EPA Method 160.2 (total suspended solids), and USP / (microbial enumeration). The system’s fixed-base design with magnetic coupling ensures mechanical stability during extended filtration cycles, minimizing vibration-induced membrane rupture or seal failure.
Key Features
- Integrated vacuum pump with sealed induction motor (1450 rpm, 80 W nominal power), optimized for continuous duty at ≤34 L/min free-air displacement
- Magnetic mounting base for secure positioning of the VF6 borosilicate glass filtration funnel and waste bottle assembly—eliminates slippage during high-flow operation
- Quick-drain waste bottle configuration with angled outlet port and ergonomic valve lever, facilitating rapid, drip-free disposal without disassembly
- Hydrophobic 0.2 µm PTFE vent filter (included) prevents pump contamination from aerosolized liquids and meets ISO 8573-1 Class 3 particulate requirements
- Compliant with IEC 61000-6-3 (EMC emissions) and IEC 61000-6-2 (immunity), certified for use in GLP and GMP-aligned laboratories
- Low-noise operation (50 dB(A) at 1 m) suitable for shared analytical suites and cleanroom-adjacent workspaces
Sample Compatibility & Compliance
The VF205A supports filtration of diverse sample matrices—including potable and wastewater, pharmaceutical suspensions, food homogenates, and HPLC/GC mobile phase solvents—without compromising filter integrity or analyte recovery. Its VF6 glassware set (DIN 12451-compliant) withstands thermal shock up to 150 °C and chemical exposure to dilute acids, bases, and common organics (e.g., acetonitrile, methanol, chloroform). The included 1 µm glass fiber filter paper complies with ASTM D2974 (total suspended solids determination) and is ash-free (<0.01% residue after 550 °C ignition), ensuring minimal background interference in gravimetric analysis. All wetted components are non-leaching and certified per USP Class VI biological reactivity standards.
Software & Data Management
As a standalone mechanical filtration platform, the VF205A operates without embedded firmware or digital controls. However, its consistent performance parameters—vacuum stability, flow linearity, and cycle repeatability—are fully documentable within laboratory information management systems (LIMS) and electronic lab notebooks (ELN). The system’s analog interface (single-stage on/off switch) simplifies 21 CFR Part 11 compliance when paired with audit-trail-enabled loggers for time-stamped start/stop events and ambient condition monitoring. Calibration records for vacuum level verification (using traceable NIST-certified gauges) and preventive maintenance logs are maintained per ISO/IEC 17025 Clause 6.4.3.
Applications
- Quantitative determination of total suspended solids (TSS) in environmental water samples per APHA Standard Methods 2540D
- Membrane filtration-based microbial enumeration (coliforms, E. coli, Pseudomonas) in food, beverage, and pharmaceutical manufacturing QC labs
- Preparative cleanup of HPLC mobile phases and GC solvent systems prior to instrument injection
- Removal of particulates from cell culture supernatants and protein purification buffers under aseptic conditions
- Routine clarification of reaction mixtures in synthetic organic chemistry workflows
FAQ
What regulatory standards does the VF205A support for TSS testing?
It conforms to ISO 5667-12, EPA 160.2, and APHA 2540D for suspended solids quantification, including dimensional tolerances for funnel geometry and vacuum stability thresholds.
Can the system be used with aggressive solvents like THF or DMF?
Yes—provided the 0.2 µm PTFE vent filter and silicone tubing are verified for compatibility; for prolonged exposure, fluoropolymer-reinforced tubing is recommended.
Is the vacuum pump serviceable in the field?
The sealed motor unit requires return-to-factory servicing; however, the PTFE vent filter and glass components are user-replaceable with standard DIN-threaded fittings.
Does the kit include calibration documentation?
A factory test report verifying vacuum level (≥150 mbar) and airflow (≤34 L/min) at rated voltage is supplied; full metrological calibration is available upon request.
How is the magnetic base secured to stainless steel surfaces?
The neodymium magnet array delivers >12 N holding force on ferromagnetic substrates; non-magnetic benches require optional adhesive-mounting plates (accessory code VF-MP1).
