Description
Three-necked round-bottom flask, 50 ml, is a compact DURAN® vessel with centre neck 14/23 and side necks 14/23, the side necks angled for convenient multi-port access. The small working volume suits micro- and small-scale synthesis, where simultaneous connection of a condenser, addition funnel or sensor is still required. Angled side necks improve clearance around the centre joint and help keep apparatus compact on a heating mantle or stand. Uniform NS 14/23 joints on centre and side necks allow direct mating with matching ground-glass components. Supplied as 1 pc at a weight of 0,060 kg, the flask is easy to handle and store in teaching and research laboratories. This model from manufacturer Lenz belongs to the DURAN® range of round flasks with ground glass joints. The three-neck configuration supports reflux, controlled reagent addition and stirring on a single small vessel. Clear joint and capacity specification simplifies selection alongside other NS 14/23 glassware for preparative and analytical workflows.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Three-necked round-bottom flask, 50 ml, Centre neck 14/23, side neck 14/23
What is this article?
Three-necked round-bottom flask, 50 ml, Centre neck 14/23, side neck 14/23 is the article on this page. Luminix Health distributes Lenz for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, in Labware.
A round-bottom flask is the heating flask of a distillation or a reflux. The curved wall takes the heat, and the ground neck connects to a still head or a condenser. The joint size, not only the volume, has to match the rest of the set.
A beaker is an open working vessel: easy to pour, poor as a measure. An Erlenmeyer flask has a flat base and a conical wall so a liquid can be swirled without climbing out. A round-bottom flask is for heating under a condenser, because the heat meets a curved wall and the joint at the neck connects to the rest of the glassware. Borosilicate is the glass that survives the temperature change. These forms are listed under ISO laboratory glassware.
