WIGGENS V300A Vacuum Filtration System with Magnetic Drain Bottle

Overview

The WIGGENS V300A Vacuum Filtration System is an integrated, modular liquid aspiration platform engineered for reproducible, operator-safe vacuum-assisted filtration in regulated and research laboratory environments. It operates on the principle of controlled negative pressure generation via a diaphragm vacuum pump, enabling rapid separation of suspended solids from aqueous and organic solutions across diverse sample matrices. The system’s core architecture comprises three interoperable subsystems: a low-noise, oil-free V300-series vacuum pump; a VF6-configured filtration assembly featuring a 300 mL borosilicate glass filter funnel, precision-ground 47/50 mm glass frit base, and PTFE-sealed silicone stopper; and a 1000 mL drain-type collection bottle with magnetic base and integrated quick-release valve for hands-free waste disposal. This design eliminates manual decanting, reduces cross-contamination risk, and maintains consistent vacuum integrity during sequential filtrations—critical for microbiological membrane filtration (e.g., EPA Method 1603), total suspended solids (TSS) quantification (ASTM D5907), and preparatory sample cleanup prior to HPLC, GC, or atomic absorption analysis.

Key Features

• Oil-free diaphragm pump delivering stable vacuum ≥150 mbar and maximum flow rate of 17 L/min—optimized for high-throughput filtration without vapor lock or solvent degradation.
• Magnetic-base drain bottle with ergonomic lever-actuated valve enables rapid, drip-free waste evacuation while maintaining vacuum continuity—eliminating downtime between samples.
• VF6 filtration kit includes borosilicate glass components (filter cup, base, and collection bottle) compliant with USP and ISO 3585 standards for chemical resistance and thermal stability (−20 °C to +150 °C).
• Universal 8 mm ID silicone tubing interface compatible with all WIGGENS VF-series accessories—including stainless steel (VF9/VF11), PES-lined (VF30), and micro-volume (VF5/VF8) configurations.
• Modular compatibility with 12 standardized VF filtration kits (VF1–VF12, VF30–VF33), supporting filter diameters from 25 mm to 47 mm, volumes from 15 mL to 1000 mL, and materials including PES, stainless steel 316L, and borosilicate glass.
• CE-marked and RoHS-compliant construction; manufactured under ISO 9001 quality management system with full traceability of component sourcing and final assembly in Germany.

Sample Compatibility & Compliance

The V300A system accommodates a broad range of sample types—including potable water, wastewater, pharmaceutical suspensions, food extracts, and chromatographic mobile phases—without compromising membrane integrity or filtrate purity. Its inert borosilicate glass and PTFE-silicone wetted path ensure compatibility with aggressive solvents (e.g., acetone, methanol, 0.1 M NaOH) and acidic/basic aqueous media (pH 1–14). For regulatory applications, the system supports GLP/GMP workflows: vacuum stability meets ASTM D2974 (TSS), ISO 9308-1 (coliform enumeration), and USP sterility testing requirements. Optional VF-series accessories enable method-specific validation—e.g., VF11 (500 mL stainless steel) for heavy metal digestion residues, VF5 (15 mL glass) for trace-level HPLC vial prep, and VF30 (PES-lined magnetic funnel) for protein-rich biologics filtration.

Software & Data Management

While the V300A is a manually operated analog system, its mechanical design supports full auditability in regulated settings. All components carry engraved serial numbers and material certifications (e.g., DIN ISO 3585 glass, EN 10088-1 stainless steel 316L). The magnetic drain mechanism permits timed filtration cycles (recorded manually or via external stopwatch), and vacuum consistency can be verified using calibrated digital manometers (e.g., WIGGENS VP-100 series). Documentation packages include CE Declaration of Conformity, RoHS compliance statements, ISO 9001 manufacturing certificates, and material safety data sheets (MSDS) for all wetted parts—facilitating FDA 21 CFR Part 11 readiness when paired with validated lab notebooks or LIMS-integrated logging procedures.

Applications

• Environmental testing: Standardized TSS determination per EPA 160.2 and ISO 11923; microbial recovery (coliforms, E. coli) using 47 mm membranes in accordance with ISO 9308-1 and APHA 9222B.
• Pharmaceutical QC: Sterility testing filtration (USP ), particulate matter analysis (USP ), and active pharmaceutical ingredient (API) crystallization workups.
• Food & beverage: Yeast/mold enumeration (AOAC 977.27), turbidity reduction in juice clarification, and pesticide residue pre-concentration prior to GC-MS.
• Academic research: Solvent exchange in nanoparticle synthesis, cell culture supernatant clarification, and polymer solution degassing prior to rheological characterization.
• Chemical labs: Removal of catalyst residues after Grignard or Suzuki couplings; drying of hygroscopic reagents via solvent wash/filtration sequences.

FAQ

What vacuum level does the V300A maintain during continuous operation?
The pump sustains ≥150 mbar ultimate vacuum under load, with typical operating range between 180–220 mbar depending on tubing length, filter clogging, and ambient temperature.
Can the V300A be used with corrosive solvents such as concentrated HCl or HF?
No—while borosilicate glass and silicone are resistant to many acids, hydrofluoric acid (HF) etches glass and must be handled exclusively with PTFE or polypropylene systems (e.g., VF32/VF33 with PP components).
Is the magnetic drain bottle autoclavable?
The 1000 mL borosilicate glass bottle is autoclavable at 121 °C for 20 min; however, the magnetic base assembly (including neodymium magnets and silicone gasket) is not autoclave-rated and must be sterilized separately via ethanol wipe or UV exposure.
How often should the pump’s diaphragm be replaced?
Under normal use (≤4 h/day, non-aggressive vapors), the diaphragm requires replacement every 12–18 months; service intervals are extended with optional inline condensate traps (WIGGENS VT-100) for high-volatility solvents.
Does the system comply with EU Medical Device Regulation (MDR) requirements?
The V300A is classified as Class I general laboratory equipment—not a medical device—and therefore falls outside MDR scope; it is CE-marked under the Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU.
