WIGGENS V300B Integrated Vacuum Filtration System

Overview

The WIGGENS V300B Integrated Vacuum Filtration System is an engineered laboratory solution for reliable, repeatable, and operator-safe vacuum-assisted filtration across environmental, pharmaceutical, food & beverage, and analytical chemistry applications. Based on the principle of pressure-driven liquid-phase separation through microporous membranes, the system utilizes a diaphragm-type vacuum pump to generate stable negative pressure—enabling efficient removal of liquid phase while retaining suspended particulates or microorganisms on the filter surface. Its modular architecture integrates a 300 mL borosilicate glass filtration funnel, a 1000 mL quick-drain waste bottle with magnetic base stabilization, and a compact, oil-free V300 vacuum pump—designed to minimize footprint while maximizing operational stability during extended use. The system is optimized for routine compliance-driven workflows including ISO 9308-1 (E. coli detection), ASTM D5907 (suspended solids in water), USP microbiological enumeration, and EPA Method 160.1 (total suspended solids in drinking water).

Key Features

• Stable vacuum performance with ≥150 mbar ultimate vacuum level and ≤17 L/min free-air flow rate—sufficient for rapid filtration of low-to-medium viscosity aqueous samples without membrane rupture or channeling.
• Magnetic base assembly ensures secure positioning of the waste bottle during active filtration and enables one-handed, spill-resistant waste drainage—critical for high-throughput labs processing multiple samples per shift.
• Borosilicate glass filtration funnel (300 mL capacity) with 9.6 cm² effective filtration area and standardized 47/50 mm filter support—compatible with common sterile and non-sterile membrane types (e.g., cellulose ester, polyethersulfone, glass fiber).
• Oil-free, maintenance-light V300 diaphragm pump meets ISO 8573-1 Class 0 air purity requirements—eliminating risk of hydrocarbon contamination in sensitive analytical sample preparation (e.g., HPLC mobile phase filtration, GC solvent purification).
• Integrated VF1 glass filtration kit includes silicone tubing (ID 8 mm), 1 µm glass fiber filter discs, and all necessary adapters—pre-configured for immediate deployment under GLP-compliant documentation protocols.
• CE-marked power supply (220–240 V / 50 Hz, 60 W) ensures compatibility with standard European and international lab electrical infrastructure.

Sample Compatibility & Compliance

The V300B supports filtration of aqueous, mildly acidic/basic, and low-organic-content solutions typical in environmental monitoring (e.g., wastewater, surface water), pharmaceutical QC (sterility testing filtrates), and food safety assays (coliform enumeration). It is not intended for strong oxidizers, halogenated solvents, or highly viscous suspensions (>500 cP). All wetted components—including funnel, waste bottle, and silicone tubing—are chemically resistant per ISO 10993-5 cytotoxicity screening guidelines. The system facilitates adherence to regulatory data integrity standards: vacuum pump operation logs (via optional external timer or lab notebook entry) support traceability for ISO/IEC 17025-accredited laboratories; its fixed configuration minimizes setup variability required for method validation per ICH Q2(R2).

Software & Data Management

The V300B operates as a standalone analog instrument without embedded firmware or digital interfaces. However, its consistent mechanical design enables seamless integration into documented manual workflows. Users may pair it with validated electronic lab notebooks (ELNs) such as LabArchives or Benchling to record filtration parameters (start/end time, membrane lot number, sample ID, observed flow behavior). For audit readiness, the absence of programmable logic eliminates 21 CFR Part 11 validation burden—making it suitable for GMP environments where simplicity, reproducibility, and paper-based SOP execution are prioritized.

Applications

• Determination of total suspended solids (TSS) in potable water, wastewater, and industrial effluents per EPA 160.1 and ISO 11923.
• Microbiological membrane filtration for coliform, E. coli, and Pseudomonas aeruginosa enumeration in food, beverages, and pharmaceutical waters.
• Pre-filtration of HPLC mobile phases and GC injection solvents to prevent column fouling and detector contamination.
• Clarification of cell culture supernatants or antibody-containing buffers prior to ultrafiltration or chromatography.
• Routine particulate removal from reagent-grade chemicals and calibration standards used in trace elemental analysis (e.g., ICP-MS sample prep).

FAQ

Is the V300B suitable for filtering organic solvents such as acetone or chloroform?
No. The silicone tubing and diaphragm pump materials are not chemically compatible with aggressive organics. Use only with aqueous or low-concentration alcohol/water mixtures.
Can I replace the 1 µm glass fiber filters with other pore sizes?
Yes—provided the replacement membrane fits the 47/50 mm support and maintains flat seating. Common alternatives include 0.45 µm mixed cellulose ester (for microbiology) or 0.22 µm PVDF (for sterile filtration).
Does the system include vacuum gauge or pressure regulation?
No. The V300B delivers fixed vacuum output. For applications requiring adjustable pressure control, an external vacuum regulator or electronic controller must be added upstream.
What is the expected service life of the V300 pump under continuous operation?
Rated for >10,000 hours of intermittent use. Diaphragm replacement is recommended every 2–3 years in high-frequency labs; no scheduled lubrication is required.
Is the VF1 glassware autoclavable?
Yes—all VF1 components (funnel, waste bottle, adapter) are borosilicate 3.3 glass and withstand standard autoclave cycles (121 °C, 20 min, saturated steam).
