Every precipitate will be collected using a Hirsch funnel. Make definite that the plastic frit disc is firmly snapped in place in your focus. Replacement frit discs are available in case it become clogged or otherwise broken. Attach the funnel to a filter flask, using the neoprene adapter to ensure a good seal among the funnel and the flask. Attach the filter flask to your vacuum line and turn the vacuum on.
