A powder funnel made of polypropylene (PP) is a laboratory apparatus used for transferring solid powders or granules into containers. The funnel is designed with a broad, flat bottom that helps to prevent spillages during transfer. Powder funnels are commonly used in laboratory settings for tasks such as transferring reagents, filling capsules or vials, or filling filter papers.

The use of a PP material makes the powder funnel durable, lightweight, and resistant to chemicals commonly used in the laboratory. Additionally, polypropylene is chemically resistant and can be used with a wide range of powders without risk of contamination or corrosion.
