Description
DURAN® funnel with long stem, also known as a Bunsen funnel, is laboratory glassware intended for transferring liquids and solids in routine analytical and preparative work. Featuring a rim diameter of 70 mm and fabricated from borosilicate glass 3.3, the funnel can accommodate a relatively large volume of material and direct it through a narrowed outlet into vessels with smaller openings. The elongated stem supports controlled pouring and filtration, helping to reduce spillage during transfer operations. A permanently fired white print provides durable, long-lasting identification that withstands repeated cleaning and laboratory use. Supplied as a single piece from manufacturer Duran/DWK Life Sciences, this Bunsen-style funnel is well suited to everyday substance transfer and filtration tasks. Its classic geometry and chemically resistant glass construction make it a practical choice for general laboratory workflows where reliable, reusable glassware is required for handling both liquid and solid samples without unnecessary loss or contamination.
This article is part of Funnels (plastic, glass & steel), in Funnels.
