Description
Ribbed funnel with 70 mm diameter is a laboratory glass funnel manufactured from DURAN tubing for reliable transfer and filtration work. Formed at a 60° angle with an overall height of 125 mm, the ribbed inner surface promotes even filter-paper seating and steady liquid flow during gravity filtration. The body is made from borosilicate glass 3.3, giving the funnel the thermal and chemical resistance expected in routine analytical and preparative chemistry. DURAN® glass construction supports clear observation of the filtrate and residue while maintaining dimensional stability under typical laboratory heating and cooling cycles. Offered in a pack of ten pieces from manufacturer Witeg, this funnel is suited to sample preparation, solvent transfer, and solid–liquid separations on the bench. The 70 mm opening balances capacity with a compact footprint, making it convenient for standard conical flasks and receiving vessels. Net weight is approximately 0,055 kg per piece, reflecting a lightweight yet sturdy glassware item for daily use in research, teaching, and quality-control laboratories handling aqueous and many organic media.

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.
