WIGGENS VF214 Vacuum Filtration Kit

Overview

The WIGGENS VF214 Vacuum Filtration Kit is an engineered laboratory solution for precise, reproducible, and contamination-controlled vacuum-assisted liquid filtration. Designed around the principles of controlled negative pressure generation and modular glassware integration, the system employs a diaphragm vacuum pump with oil-free operation to ensure chemical compatibility and eliminate risk of oil backstreaming—critical when handling HPLC mobile phases, GC solvents, or trace-level analytical samples. The kit operates at a stable vacuum level of ≥13 mbar, sufficient to support rapid filtration of aqueous and organic solutions while maintaining integrity of delicate membranes and particulate-retentive filters. Its compact, benchtop architecture integrates seamlessly into QC labs, environmental testing facilities, and pharmaceutical R&D environments where GLP-compliant sample preparation workflows are required.

Key Features

• Oil-free diaphragm pump with corrosion-resistant internal components, enabling safe use with aggressive solvents including acetonitrile, methanol, and dilute acids/bases.
• Integrated magnetic base station (Magnetic Fixing Stand) secures the VF3 filtration funnel and waste bottle assembly, minimizing tipping risk during high-flow filtration or multi-sample processing.
• Quick-drain waste bottle design with ergonomic side valve allows complete, drip-free evacuation of filtrate without disassembly—reducing operator exposure and cross-contamination between runs.
• Pre-assembled accessory set includes certified 0.2 µm PTFE hydrophobic vent filter (prevents pump damage from accidental liquid ingress) and 1 µm glass fiber filter discs compliant with ASTM D5907 for suspended solids (TSS) determination.
• Dragon100 adjustable Bunsen burner supports flame-sterilization of filtration funnels and accessories in microbiological applications per ISO 7218 and USP <61> guidelines.
• Low-noise operation (50 dB(A)) and thermally stable motor housing enable continuous duty cycles in shared lab spaces without acoustic or thermal interference.

Sample Compatibility & Compliance

The VF214 accommodates standard DIN/ISO-compatible glassware, including 100–500 mL VF3-series funnels and matching heavy-walled borosilicate waste bottles rated to −0.9 bar. It supports filtration of turbid water samples (per EPA Method 160.2), pharmaceutical suspensions (USP <788>), food homogenates, and cell culture supernatants. All included PTFE and glass fiber media meet EU Directive 2002/72/EC for food contact safety. The system’s vacuum stability and flow consistency support audit-ready documentation under ISO/IEC 17025:2017 and FDA 21 CFR Part 11–compliant data capture when paired with validated electronic logbooks.

Software & Data Management

While the VF214 operates as a standalone mechanical system, its performance parameters—including vacuum decay rate, time-to-target vacuum, and cumulative runtime—are fully recordable via external digital manometers or integrated lab information management systems (LIMS). The pump’s consistent 1450 rpm motor speed ensures repeatable air displacement across batches, supporting SOP-driven calibration intervals defined per ISO 8573-1 for compressed air quality analogs. For regulated environments, users may implement manual log entries or integrate vacuum event timestamps into ELN platforms using standard RS232 or analog 0–10 V output modules (optional add-on).

Applications

• Microbiological analysis: Membrane filtration of drinking water, beverages, and sterile pharmaceutical products per ISO 9308-1 and APHA Standard Methods 9222B.
• Environmental testing: Quantification of total suspended solids (TSS) in wastewater effluents and surface waters (ASTM D5907, EPA 160.2).
• Chromatographic sample prep: Solvent degassing and mobile phase clarification prior to HPLC, UHPLC, GC-FID, and ICP-MS injection.
• Pharmaceutical QA/QC: Particulate matter removal from parenteral formulations and excipient solutions in accordance with USP <788> and Ph. Eur. 2.9.20.
• Academic research: Rapid isolation of precipitates, crystals, or nanoparticles from reaction mixtures under inert atmosphere (when used with optional N₂ purge adapter).

FAQ

Is the VF214 suitable for filtering organic solvents such as chloroform or THF?
Yes—the oil-free diaphragm pump and PTFE-sealed valves are chemically resistant to common HPLC-grade organic solvents; however, prolonged exposure to strong oxidizers (e.g., concentrated nitric acid) is not recommended.
Can the system be validated for GMP environments?
The VF214 meets mechanical reliability criteria for IQ/OQ protocols; full PQ validation requires documented testing of vacuum stability, filter integrity (via bubble point test), and sterility assurance when used with autoclavable VF3 glassware.
What is the maximum operating temperature of the included glassware?
VF3 borosilicate filtration assemblies are rated for continuous use up to 500 °C and short-term thermal shock resistance per DIN ISO 3585.
Does the kit include a vacuum gauge?
No—a calibrated analog or digital vacuum gauge is recommended for process verification and must be selected based on required resolution (e.g., ±0.1 mbar for critical solvent filtration).
Are replacement 0.2 µm PTFE vent filters available with traceable certificates of conformance?
Yes—WIGGENS supplies PTFE vent filters with individual lot-specific CoA referencing ASTM F838-22 and pore size verification by microbial challenge testing.
