Description
Three-necked round-bottom flask, 3000 ml is a multi-neck laboratory vessel for synthetic, preparative and teaching work that needs several ground-glass connections at once. The centre neck is NS 29/32 and the two side necks are NS 14/23; the side necks are angled to give clearer access for condensers, dropping funnels, gas inlets or thermometer adapters without crowding the centre joint. Made from DURAN® glass and offered by manufacturer Lenz, the flask suits common multi-neck setups such as simultaneous reagent addition, inert-gas blanketing, reflux and temperature monitoring during reactions or distillations. The 3000 ml working volume supports medium-scale preparations where even heating and efficient stirring matter. The round-bottom geometry promotes uniform heat transfer when used with heating mantles or oil baths, while the standardised joints mate with matching laboratory glassware. Pack size is one piece, with a net weight of 0,770 kg, making the item straightforward to stock as a dedicated reaction flask for organic and inorganic workflows that rely on angled side necks and mixed joint sizes.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Three-necked round-bottom flask, 3000 ml, Centre neck 29/32, side neck 14/23
What is this article?
Three-necked round-bottom flask, 3000 ml, Centre neck 29/32, 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.
