Bunsen funnels 100 mm Ø,

Bunsen funnel 100 mm Ø is a laboratory glass funnel produced from borosilicate glass 3.3 in line with DIN 12 446. It incorporates smooth surfaces and an approximately 150 mm long stem that facilitate controlled pouring and gravity filtration in analytical and preparative procedures. The 100 mm rim diameter supplies a generous opening for transferring larger sample volumes, solvents and reagents into receiving vessels or filtration assemblies, while the long stem ensures accurate delivery. Offered by manufacturer Marienfeld, the funnel unites the chemical durability and thermal stability of borosilicate glass 3.3 with precise geometry suited to daily laboratory practice. Delivered in packs of 10 pieces, these funnels serve research, educational and quality-control laboratories. Smooth internal and external finishes help limit residue build-up and ease cleaning between uses. The funnel is appropriate for routine decanting, filtration and general liquid handling of aqueous media and many organic solvents. Its robust construction provides consistent performance under normal laboratory conditions, making it a practical addition to standard glassware collections for reliable sample preparation.
