DWK Wheaton Vacuum Filter Holder Assembly, 90 mm, with 40/35 Joint Connection is designed for general laboratory filtration applications requiring precision and reliability. Made from high-quality borosilicate glass, it provides excellent chemical resistance and durability under vacuum conditions. The removable fritted glass support funnel ensures smooth, consistent filtration of liquids and gases, while the coarse porosity (40–60 µm) frit allows efficient particle retention. Its 1000 mL capacity enables larger volume processing, and the 40/35 joint connection ensures a tight, leak-proof seal during operation.
