Questions about Funnels

Which funnel shelf do I open?

Open the shelf that matches the job. Vacuum and paper filtration: Büchner and filter funnels. Powders: powder funnels. Separating two liquid phases: separating funnels. Adding a reagent: dropping funnels. A small sample through a membrane: syringe filters.

Glass, polypropylene, PTFE or porcelain funnel?

The material is in the title. Glass and porcelain are the usual rigid funnels. Polypropylene is the plastic named as polypropylene. PTFE is for liquids that attack glass. Match the outlet and the top diameter to the receiving vessel. Questions: sales@luminixhealth.com.

Long or wide stem: which funnel for gravity filtration or powders?

Use an analytical funnel with a long stem for gravity filtration, and a powder funnel with a wide stem to transfer solids. Choose the funnel diameter to suit your filter paper. Unsure which one fits? Ask sales@luminixhealth.com.

Which funnel diameter suits my filter paper?

The folded filter should stay just below the rim of the funnel, so liquid cannot run past it. For a conical funnel, that means a round filter clearly larger than the funnel diameter; the product pages of the funnel and the filter paper list the sizes. For a Buchner funnel, pick a round filter that just covers the perforated plate without rising up the wall. See filter paper. Need advice for your set-up? Mail sales@luminixhealth.com.

Why Funnels?

A funnel guides a liquid or a powder into a narrower mouth. A filter funnel holds a paper. A Büchner funnel is the flat perforated plate used with vacuum. A separating funnel has a stopcock so two liquid layers can be run off one at a time. A dropping funnel adds a reagent slowly into a reaction. The bore and the stopcock are the parts that matter. This glassware is listed under ISO laboratory glassware.
