PYREX 47mm Microfiltration Glass Assembly with 1L Funnel and 4L Flask – 33980-1L

The PYREX 47mm Microfiltration All-Glass Assembly with 1L Graduated Funnel and 4L Collection Flask (33980-1L) is a professional laboratory vacuum filtration apparatus designed for high-volume liquid filtration, High-Performance Liquid Chromatography (HPLC) mobile phase preparation, particulate contamination analysis and general laboratory microfiltration. Manufactured by Corning under the PYREX brand, this complete filtration assembly features a 1,000mL graduated glass funnel, a 4,000mL Erlenmeyer collection flask, a 47mm fritted glass support base and an aluminum securing clamp. The all-glass filtration design offers excellent chemical compatibility with many organic solvents, while the coarse-porosity fritted glass support accommodates standard 47mm membrane filters. The apparatus provides an effective solution for laboratories requiring consistent vacuum-assisted filtration, sample clarification and solvent preparation. It is suitable for pharmaceutical laboratories, analytical chemistry laboratories, research institutions, environmental testing facilities, universities and industrial quality control laboratories.
