Overview
The WIGGENS V300B Vacuum Filtration Kit is a purpose-engineered, oil-free laboratory vacuum system designed specifically for standardized suspended solids (SS) determination in environmental, municipal, and industrial water quality analysis. Based on the principle of pressure-driven membrane filtration under controlled vacuum, the system enables quantitative recovery of particulate matter retained on high-efficiency 1 µm glass fiber filters. Its compliance with core regulatory methodologies—including ISO 5667-12, EPA Method 160.2, and ASTM D5907—makes it suitable for accredited laboratories performing routine SS testing in wastewater, surface water, drinking water, and effluent monitoring programs. The V300B integrates a corrosion-resistant, maintenance-free diaphragm vacuum pump with a magnetically coupled VF1 filtration assembly, eliminating mechanical clamps and minimizing operator intervention while ensuring reproducible filtration kinetics and minimal sample loss.
Key Features
- Oil-free diaphragm pump with PTFE-coated wetted parts and integrated inlet particulate/moisture filter—ensures zero hydrocarbon contamination and extends service life under continuous duty cycles.
- Magnetic coupling design between the VF1 glass funnel and collection flask—enables rapid, leak-tight assembly without clamps or O-rings, reducing setup time and cross-contamination risk during high-throughput SS analysis.
- Optimized filtration geometry: 9.6 cm² effective filter area (47/50 mm diameter), paired with a 300 mL borosilicate glass funnel and 1000 mL calibrated collection flask—meets volumetric accuracy requirements per ISO 5667-12 Annex A.
- Low-noise operation (<52 dB(A)) achieved via direct-drive motor architecture and vibration-damping base—maintains acoustic compatibility in shared analytical labs and QC environments.
- 60 W energy-efficient motor with thermal overload protection—designed for extended unattended operation during multi-sample batch processing.
Sample Compatibility & Compliance
The V300B accommodates aqueous samples across pH 2–12 and turbidities up to 500 NTU without membrane clogging or flow decay. It is validated for use with standard 1 µm glass fiber filters (e.g., Whatman GF/C, Pall BioTrace™ GF) and compatible with gravimetric SS protocols requiring pre- and post-drying at 103–105 °C. All wetted components comply with USP Class VI and FDA 21 CFR Part 177 for indirect food contact. System documentation supports GLP/GMP audit readiness, including traceable calibration certificates for vacuum gauge (±2 mbar accuracy) and flask volume certification (±0.5% tolerance). The kit meets CE marking requirements under the EU Machinery Directive 2006/42/EC and Electromagnetic Compatibility Directive 2014/30/EU.
Software & Data Management
While the V300B operates as a standalone analog instrument, its design facilitates seamless integration into digital lab workflows. Vacuum output is stable and repeatable (±3% variation over 8-hour operation), enabling reliable correlation with electronic balance readings and LIMS data entry. Optional analog-to-digital vacuum transducer modules (sold separately) support real-time logging via RS-485 or USB interfaces, generating timestamped pressure profiles compliant with 21 CFR Part 11 audit trails when paired with validated acquisition software. All accessories—including silicone tubing, filter holders, and spare glassware—are assigned unique catalog numbers aligned with ChemVak’s master inventory database for automated reordering and asset tracking.
Applications
- Regulatory suspended solids quantification per ISO 5667-12, EPA 160.2, and APHA 2540 D.
- Pre-filtration of environmental water samples prior to ICP-MS, IC, or TOC analysis.
- Clarification of biological suspensions in microbiology prep labs where oil-free conditions are mandatory.
- Removal of precipitates from titration reagents or buffer stock solutions in pharmaceutical QC labs.
- Supporting ASTM D3921 for total suspended particulates in stormwater runoff characterization.
FAQ
What filtration standards does the V300B support?
It is validated for ISO 5667-12 (water quality — sampling — part 12: guidance on filtration techniques), EPA Method 160.2 (suspended solids), and APHA Standard Method 2540 D.
Can the V300B be used with organic solvents?
No — for solvent-based applications, the C300A corrosion-resistant diaphragm pump variant with PTFE-wetted components is recommended.
Is the 1 µm glass fiber filter included in the kit certified for gravimetric analysis?
Yes — supplied filters meet ISO 9001-certified manufacturing specifications and are pre-ashed (550 °C, 2 h) with ash weight ≤0.0002 g per filter.
Does the magnetic coupling maintain vacuum integrity across temperature gradients?
Yes — borosilicate glass and NBR elastomer seals retain sealing force from 5 °C to 40 °C; no measurable leakage observed at 150 mbar under thermal cycling tests.
What maintenance intervals are required for the V300B pump?
None — the oil-free diaphragm design requires only periodic inlet filter replacement (every 6 months under typical lab use) and visual inspection of tubing integrity.
