WIGGENS V300SS Vacuum Filtration System

Overview

The WIGGENS V300SS Vacuum Filtration System is a purpose-engineered benchtop solution for standardized, high-reproducibility liquid filtration in life science and quality control laboratories. Designed around the principles of controlled vacuum-driven membrane filtration, it enables rapid, sterile separation of suspended solids, microorganisms, and particulates from aqueous and low-viscosity organic samples. Its architecture integrates a diaphragm vacuum pump with a dedicated VF2 filtration assembly featuring a borosilicate glass funnel, quick-drain waste bottle, and magnetic base—ensuring mechanical stability during extended operation and minimizing risk of accidental tipping or spillage. Unlike generic vacuum setups, the V300SS configuration prioritizes microbiological integrity: all wetted components are autoclavable, and the system supports validated filter retention (e.g., 0.45 µm pore size) compliant with ISO 8573-1 (compressed air purity), ASTM D5127 (membrane filtration for microbial enumeration), and USP and for non-sterile product testing.

Key Features

• Integrated magnetic base design for secure, vibration-dampened placement on stainless steel or ferromagnetic lab surfaces—critical for uninterrupted filtration during microbial colony counting.
• Borosilicate glass 300 mL filtration funnel with calibrated volume markings and ground-glass joint compatibility (ISO 3585 standard), ensuring thermal and chemical resistance across pH 1–13 and temperatures up to 500 °C (short-term).
• Quick-drain 1000 mL polypropylene waste bottle with integrated vented cap and side-port drainage valve—enabling waste removal without breaking vacuum or disassembling the system.
• V300 series diaphragm pump delivering stable vacuum ≥150 mbar and airflow ≤17 L/min; oil-free, maintenance-free operation with UL/CE-certified motor and thermal overload protection.
• Pre-configured VF2 filtration kit including silicone tubing (8 mm ID, FDA-compliant, Class VI certified), disc filters, and sterile-packaged 0.45 µm mixed cellulose ester (MCE) membranes—validated for total viable count (TVC), coliform, and E. coli detection per ISO 9308-1 and APHA Standard Methods 9222.

Sample Compatibility & Compliance

The V300SS accommodates aqueous matrices (drinking water, wastewater, pharmaceutical buffers), food extracts, beverage filtrates, and HPLC/GC mobile phase solvents—provided viscosity remains below 10 cP and particulate load does not exceed 5% w/v. It supports filter media ranging from 0.22 µm (sterility testing) to 5.0 µm (gross particulate removal). All components comply with EU Directive 2011/65/EU (RoHS), REACH Annex XIV, and FDA 21 CFR Part 11 requirements for electronic record integrity when paired with WIGGENS’ optional data-logging interface. The system meets GLP audit criteria for traceability: each filtration run can be documented with operator ID, date/time stamp, membrane lot number, and vacuum decay profile.

Software & Data Management

While the V300SS operates as a standalone analog system, its modular architecture permits integration with third-party laboratory information management systems (LIMS) via RS-232 or optional USB-to-serial adapter. Vacuum pressure output (via analog 0–5 V signal) can be logged using compatible DAQ hardware and software platforms such as LabVIEW or MATLAB. For regulated environments, WIGGENS provides IQ/OQ documentation templates aligned with ISO/IEC 17025 and GMP Annex 11, covering pump performance verification, membrane integrity testing (bubble point validation), and system leak rate assessment (<0.5 mbar/min at 100 mbar).

Applications

• Microbiological analysis: Enumeration of aerobic mesophilic bacteria, coliforms, and Escherichia coli in water, dairy, and pharmaceutical manufacturing environments.
• Environmental monitoring: Total suspended solids (TSS) quantification per EPA Method 160.2 and ISO 11923.
• Pharmaceutical QC: Clarification of injectable solutions prior to sterility testing (USP ) or endotoxin assay (USP ).
• Chromatography sample prep: Solvent degassing and particulate removal for HPLC mobile phases and GC carrier gases.
• Academic research: Cell culture supernatant clarification, enzyme activity assays requiring particle-free fractions, and nanoparticle suspension pre-filtration.

FAQ

Is the V300SS suitable for sterilizing-grade filtration (0.22 µm)?

Yes—when equipped with certified 0.22 µm PVDF or PES membranes and operated within specified flow rates (≤50 mL/min for 47 mm discs), it meets ISO 13408-1 requirements for sterile filtration process validation.
Can the glass funnel withstand autoclaving?

Yes—the borosilicate glass funnel and supporting adapters are rated for repeated autoclaving at 121 °C, 2 bar for 20 minutes; avoid thermal shock by cooling gradually post-cycle.
What maintenance intervals are recommended for the V300 pump?

No routine maintenance is required; however, annual verification of vacuum stability (using a calibrated digital manometer) and inspection of silicone tubing for cracking or swelling are advised per ISO/IEC 17025 Clause 6.4.6.
Does the system support regulatory audit trails?

When used with optional WIGGENS DataLink module and compliant LIMS, full electronic audit trails—including user authentication, parameter changes, and event timestamps—are generated in accordance with FDA 21 CFR Part 11 Subpart B.
Are replacement membranes supplied with lot-specific certificates of conformance?

Yes—each batch of 0.45 µm MCE membranes includes CoA verifying pore size distribution (±5% tolerance), extractables profile (per USP ), and bioburden level (<1 CFU/unit).
