Description
Funnel with NS stopcock 24/29 is a larger laboratory glass funnel featuring a standard ground joint and integrated NS stopcock for controlled dispensing and filtration of liquids. It is constructed with a 60° cone angle, a diameter of 70 mm and a 4 mm bore, and includes a stopcock plug together with threaded stopcock security to maintain a secure seal during use. Supplied as a single unit weighing 0,101 kg net, the funnel is designed for analytical and preparative applications that require greater capacity while retaining precise flow regulation. The NS 24/29 joint ensures straightforward connection to complementary ground-joint glassware without extra adapters. Produced by Witeg, this analytical funnel supports efficient liquid handling in chemistry, biochemistry and quality-control laboratories. Its robust dimensions make it particularly useful for bulk sample work, solvent transfers and separations where both volume and reliable stopcock performance are important. The combination of standard joint sizing and integrated shut-off capability streamlines everyday laboratory procedures involving glass apparatus.
