Description
Two-necked flask, DURAN®, 100 ml is a compact round-bottom laboratory flask with an angled side neck for small-scale multi-port chemistry. The centre neck is NS 29/32 and the angled side neck is NS 14/23, providing a common combination of joint sizes for condensers, stoppers, thermometers or small addition funnels. This DURAN® two-necked flask from manufacturer Lenz is supplied as 1 pc and has a stated weight of 0,083 kg, making it easy to handle on micro- and mini-scale setups. The 100 ml capacity is well suited to exploratory synthesis, teaching experiments and analytical sample preparation where two simultaneous connections are required. The angled side-neck arrangement improves access beside the main joint and helps keep clamps and stands clear of the working zone. Standard ground joints support interchange with existing European glassware inventories. Typical applications include reflux with side-arm sampling, inert-gas blanketing during addition, and other routines that rely on round flasks with ground glass joints in research and quality-control laboratories.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Double neck round bottom flasks, 100 ml, 24/29, 14/23
What is this article?
Double neck round bottom flasks, 100 ml, 24/29, 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.
