Description
Filter funnel of borosilicate glass 3.3 with 75 ml capacity, model 11 D and porosity 3, is intended for vacuum filtration work in chemical and analytical laboratories. This glass nutsche incorporates a fritted disc of porosity grade 3, suited to retaining medium-sized particles and crystalline precipitates during solid-liquid separations. Fabricated from durable Boro 3.3, the funnel offers strong chemical resistance and good thermal stability for repeated use with aqueous and many organic media. The compact 75 ml working volume supports small-batch preparations, sample clean-up and routine analytical filtrations where visual monitoring of the process is helpful. Supplied as a single piece, the unit pairs readily with standard laboratory vacuum apparatus and filtration flasks. From manufacturer Brand, the model 11 D design provides consistent flow characteristics through the sintered plate while the clear glass body allows easy observation of filtrate and residue. It is a practical choice for research, teaching and quality-control environments that require reliable glass frit filtration at this scale.
