Whatman™ 3-piece Filter Funnel, 400 ml Reservoir Volume

The increased use of high-efficiency glass microfiber filters in modern laboratories has created a demand for simple and effective filter-holding systems. Whatman™ 3-piece filter funnels have been designed to complement the range of Whatman™ fine particle retention, rapid flow rate glass microfiber filters.

• Functional design: Three-piece construction; the funnel is quickly dismantled, ready for the insertion of a new filter; the glass sealing flanges of the funnel and reservoir are ground flat to ensure a good filter seal
• Positive filter clamping: All retained solids are deposited within the filter circle; edge clamping prevents peripheral loss and possible passage of solution around, rather than through, the filter circle
• Simple to clean The parts can be quickly and efficiently cleaned because of the simplicity of the design
• For quick and easy filtration, Whatman™ 3-piece filter funnels are available with a choice of plates; they also come in several sizes to match your needs
• Acrylic plate: Supplied as standard; suitable for filtration of most aqueous solutions; maximum working temperature 65°C
• Polypropylene plate: Optional extra; recommended for most acids (except concentrated nitric acid and fuming sulfuric acid) at room temperature; suitable for most alcohols, glycols, ethers, and ketones; maximum working temperature 100°C
• PTFE plate: Optional extra; for virtually all common acids, alkalis and solvents at temperatures up to 100°C; maximum working temperature 200°C
• Application: For quick and easy filtration
