PYREX 47mm Fritted All-Glass Support Base with Tubulation – 33982-B

The PYREX 47mm Fritted All-Glass Support Base with Tubulation (33982-B) is a laboratory filtration component designed for assembling vacuum-assisted microfiltration systems. Manufactured by Corning under the PYREX brand, this support base features a coarse-porosity fritted glass disc that provides stable support for 47mm membrane filters during laboratory filtration procedures. The integrated glass tubulation enables connection to a suitable vacuum source, facilitating efficient filtration of liquid samples, laboratory solvents and analytical solutions. It is designed for use with PYREX 300mL graduated glass funnel (33971-300) and 1,000mL graduated glass funnel (33971-1L). The all-glass construction offers excellent chemical compatibility with many laboratory solvents, making it suitable for High-Performance Liquid Chromatography (HPLC) mobile phase preparation, pharmaceutical analysis, environmental testing and routine laboratory microfiltration. This component is suitable for research laboratories, pharmaceutical companies, diagnostic laboratories, universities and industrial quality control facilities.
