Unique Magnetic Seal Allows Easy,
One-Handed Vacuum Filtration of Liquids

• No-leak magnetic seal allows one-hand operation.  
• Polyphenylsulfone construction is compatible with anti-foaming agents and many other solvents.
• Convenient.  150 mL size allows for easy fit into small autoclaves and 500 mL size is ideal for filtration of large samples.
• Sturdy and safe. Polyphenylsulfone construction provides durability and added safety at a cost less than most glass funnels.
• Forceps access point allows easy filter retrieval.
• Graduated at 50 mL increments for accurate sample measurement.

Applications

• Use for the Membrane Filter (MF) Technique
• Municipal water treatment testing
• Surface water analysis
• Plant process water testing
• Drinking water analysis
