PYREX 47mm Microfiltration Glass Assembly with 300mL Funnel and 1L Flask – 33980-300

The PYREX 47mm Microfiltration All-Glass Assembly with 300mL Funnel and 1L Flask (33980-300) is a high-quality laboratory vacuum filtration apparatus designed for 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 300mL graduated glass funnel, a 1L Erlenmeyer collection flask, a 47mm fritted all-glass support base and an aluminum securing clamp. Constructed using durable PYREX borosilicate glass, the apparatus offers excellent chemical resistance to many organic solvents and laboratory reagents. Its coarse-porosity fritted glass support accommodates standard 47mm membrane filters, providing a stable filtration platform during vacuum-assisted filtration procedures. The assembly is suitable for pharmaceutical laboratories, research institutions, universities, analytical chemistry laboratories, environmental testing facilities and industrial quality control laboratories. Its reusable components and replaceable glassware make it a practical choice for laboratories requiring reliable sample preparation and liquid filtration.
