Overview
The WIGGENS VF204 Vacuum Filtration Kit is a purpose-engineered laboratory system designed for reliable, efficient, and contamination-controlled vacuum-assisted filtration across diverse analytical and quality control workflows. Built upon the principles of controlled negative pressure generation and gravity-assisted liquid-phase separation, the VF204 integrates a high-efficiency diaphragm vacuum pump with a modular borosilicate glass filtration assembly (VF3 series), enabling consistent performance in both routine and regulated environments. Its design prioritizes operator safety, sample integrity, and procedural reproducibility—critical requirements in microbiological testing, environmental water analysis, and chromatographic sample preparation. The system operates under a stable vacuum level of ≥100 mbar, sufficient to support rapid filtration of low-viscosity aqueous and organic solutions while maintaining compatibility with delicate membranes and fragile filter media.
Key Features
- Robust diaphragm pump architecture with oil-free operation, ensuring zero risk of hydrocarbon contamination in filtrates—essential for HPLC mobile phase purification and trace-level elemental analysis (e.g., AA).
- Integrated quick-drain waste bottle with magnetic base mount, minimizing manual handling and reducing spill risk during high-throughput filtration sequences.
- VF3-series borosilicate glass filtration funnel and receiving flask (DIN 12567-compliant), resistant to thermal shock and chemical corrosion from common solvents including acetonitrile, methanol, and dilute acids/bases.
- Hydrophobic 0.2 µm PTFE vent filter prevents backstreaming of moisture or vapors into the pump head, extending service life and maintaining vacuum stability over extended duty cycles.
- Low-noise operation (50 dB(A)) and compact footprint (7.1 kg total mass) enable deployment on shared benchtops without compromising acoustic comfort or spatial efficiency.
- Included 1 µm glass fiber filter paper provides high particle retention for suspended solids (TSS) quantification per ISO 5667-12 and EPA Method 160.2.
Sample Compatibility & Compliance
The VF204 supports filtration of aqueous matrices (drinking water, wastewater, food extracts, pharmaceutical suspensions) and organic solvent mixtures commonly used in LC/GC sample cleanup. Its components comply with DIN 12567 (laboratory glassware), ISO 8573-1 (compressed air purity classes, by analogy for clean vacuum delivery), and USP for extractables testing of glassware. When used with certified filter media, the system meets method requirements for ASTM D5907 (total suspended solids), ISO 7894 (microbiological membrane filtration), and pharmacopeial standards for sterility testing (USP , Ph. Eur. 2.6.1). All wetted parts are non-leaching and autoclavable (glass components up to 121 °C), supporting GLP/GMP-aligned documentation of cleaning validation.
Software & Data Management
The VF204 is a standalone mechanical system with no embedded firmware or digital interface. As such, it requires no software installation, network connectivity, or cybersecurity configuration—reducing validation burden in regulated laboratories. Vacuum performance is monitored via analog gauge (optional add-on); all operational parameters—including run duration, filter type, lot number, and sample ID—are documented manually or integrated into existing LIMS/ELN platforms via standardized SOP templates. The absence of electronic controls ensures full compliance with FDA 21 CFR Part 11 when paired with audit-trail-enabled lab notebooks or validated electronic records systems.
Applications
- Microbial enumeration in food, beverage, and pharmaceutical products using membrane filtration (ISO 7894, AOAC 991.14).
- Determination of total suspended solids (TSS) in surface water, wastewater, and drinking water per ISO 5667-12 and EPA 160.2.
- Purification of HPLC mobile phases and GC carrier gases through particulate removal and moisture scavenging.
- Pre-concentration of analytes prior to atomic absorption (AA) or ICP-MS analysis, especially in environmental monitoring programs.
- Removal of catalyst residues or precipitates during synthetic chemistry workups under inert atmosphere (when coupled with Dragon100 Bunsen burner for flame sterilization).
FAQ
Is the VF204 suitable for filtering corrosive solvents such as concentrated HCl or HF?
No. While the VF3 glass components resist mild acids and bases, hydrofluoric acid and fuming sulfuric acid are incompatible. Use only with solvents listed in Corning PYREX® chemical resistance charts.
Can the system be validated for GMP environments?
Yes—its mechanical design, material traceability (DIN/ISO-certified glass), and absence of undocumented firmware simplify IQ/OQ/PQ execution. Documentation templates are available upon request.
What is the recommended maintenance interval for the diaphragm pump?
Inspect inlet filters quarterly; replace diaphragm and valves every 12 months under continuous use, per WIGGENS Service Bulletin SB-VF204-2023.
Does the kit include calibration certificates?
No. Calibration of vacuum gauges or flow meters must be performed externally using NIST-traceable standards; WIGGENS provides metrology-ready mounting interfaces.
Is the Dragon100 Bunsen burner compatible with natural gas supply?
It is configured for propane or butane. Conversion to natural gas requires an approved regulator and pressure adjustment—contact WIGGENS Technical Support before modification.
