NALGENE® 140 Analytical Filter Funnels, polystyrene, Cellulose Nitrate membrane

Ideal for use with filtering flasks or manifolds. Upper chambers are graduated at 150mL. Particularly useful for large volume analytical applications (as long as the membrane continues to flow). Convenient snap-away design with removable membrane. Safer and easier to use than cumbersome glass and metal funnels. Each package contains a NALGENE® vacuum gasket to replace a stopper or adapter with 9/16 inch or larger opening.
