Laboratory Glass Filtering Funnels are laboratory glassware used for filtering liquids and suspensions. They are equipped with a stem to allow them to be securely attached to a flask or container and are used in a variety of laboratory procedures.
Types of Laboratory Glass Filtering Funnels:
Büchner Funnel: It is a filtering funnel with a fritted disc at the bottom, used for filtering liquids with a high solid content.
Hirsch Funnel: It is a filtering funnel with a fritted disc at the bottom and a side arm, used for filtration under reduced pressure.
Buchner/Hirsch Funnel: It is a combination of Büchner and Hirsch funnels, used for both normal and vacuum filtration.
Separatory Funnel: It is a filtering funnel with a stopcock, used for separating liquids of different densities.
Each type of laboratory glass filtering funnel has its specific applications and is used based on the requirement of the laboratory procedure being performed. Proper cleaning and maintenance of filtering funnels is important to ensure accurate and consistent results in laboratory experiments.
