Description
Dosing funnel for solids 250 ml NS 29/32 is a laboratory dosing funnel built for the metered addition of pulverulent substances. With a working volume of 250 ml and a core-and-sleeve ground joint NS 29/32, it connects readily to common reaction vessels and apparatus. A vertical screw conveyor paired with a cooled lower section enables controlled, continuous delivery of powdery materials while assisting temperature management during transfer. This arrangement suits organic synthesis, formulation work and other experimental sequences that demand accurate solid dosing under closed conditions. The funnel is offered by manufacturer Witeg and has a net weight of 0,8 kg; it is supplied as one piece for immediate laboratory use. Its standardised NS 29/32 joint and vertical feed design simplify integration into existing glassware trains. Researchers handling fine solids will appreciate the combination of capacity, screw feed and cooled base for reliable powder introduction without compromising joint compatibility or process control.
This article is part of Funnels (plastic, glass & steel), in Funnels.
