Description
Three-necked round-bottom flask, 1000 ml is a laboratory glass vessel designed for multi-neck reaction, reflux and distillation assemblies. It features a large centre neck with ground joint 45/40 and two side necks with ground joints 29/32. The side necks are angled, giving practical clearance for condensers, addition funnels, probes or gas inlets while the flask is seated in a heating mantle or bath. Made from DURAN® glass and available from manufacturer Lenz, the product forms part of the standard range of round flasks with ground glass joints. The 1000 ml capacity suits medium-scale organic synthesis, multi-component reactions and preparative chemistry where three simultaneous ground-joint connections are needed. Round-bottom geometry promotes uniform heating and efficient stirring. Supplied as a single piece weighing 0,344 kg, the flask aligns with common NS joint standards and integrates with other DURAN® laboratory glassware. It is intended for research, process and teaching laboratories that build modular apparatus from interchangeable ground-glass components.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Three-necked round-bottom flask, 1000 ml, Centre neck 45/40, side neck 29/32
What is this article?
Three-necked round-bottom flask, 1000 ml, Centre neck 45/40, side neck 29/32 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.
