Description
Three-necked round-bottom flask, 500 ml is a multi-neck glass vessel for laboratory reactions that need concurrent connection of several ground-joint components. It provides 500 ml capacity with a centre neck NS 24/29 and two side necks NS 19/26. The side necks are angled, which improves working space around the flask and limits interference between attached condensers, addition funnels or measurement probes. Made from DURAN® glass by manufacturer Lenz, the flask is part of the established range of round flasks with ground glass joints for synthesis and general laboratory use. Its round-bottom profile supports steady heating and stirring when paired with mantles, baths and overhead or magnetic stirrers. Offered as 1 pc at a weight of 0,100 kg, this three-neck design suits organic preparation, solvent handling and small process studies that benefit from one central port plus two auxiliary NS joints. Joint dimensions follow common European standards, easing integration into existing glassware sets and clamp systems on the laboratory bench.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Three-necked round-bottom flask, 500 ml, Centre neck 24/29, side neck 19/26
What is this article?
Three-necked round-bottom flask, 500 ml, Centre neck 24/29, side neck 19/26 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.
