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. Swirl the precipitate in solution and quickly pour the mixture onto the filter (while the solids are still suspended). Rinse the precipitate with a minimal amount of ice-cold water. Leave the space on until the precipitate is dry (~5 min.), and take note of the mass.
