Funnels, disposable (polystyrene & polypropylene)

Polystyrene funnels are appropriate for use with mild acidic or alkali solutions. Polypropylene funnels are suitable for use with organic solvents and stronger acids and alkalis. Funnels measure approximately 60 mm (2½˝) wide at the top with a 60˚ taper to the funnel stem. Internal ribs promote faster flow and external ribs help prevent airlock. New material specifications now include up to 50% reused plastic.
