Filter Flasks

Filtering liquid samples is simple when you have a filter flask and neoprene stopper on hand. Filter flasks are modified Erlenmeyer flasks with a small spout on the side to allow liquids to be suctioned out and separated. Neoprene stoppers are simple synthetic rubber corks that can be fitted into filter flasks and Erlenmeyer flasks.
