Description
Three-necked round-bottom flask, 100 ml provides a compact multi-port vessel for laboratory synthesis, reflux and distillation where matched joint sizes simplify apparatus assembly. The centre neck is NS 29/32 and both side necks are likewise NS 29/32 and angled, allowing condensers, addition funnels, stirrer guides or gas inlets to be fitted with a consistent joint standard. The round-bottom geometry promotes uniform heating and mixing during organic reactions and multi-step preparations. Produced in DURAN® glass from manufacturer Lenz, the item is supplied as 1 pc and weighs 0,160 kg, fitting common laboratory supports, heating mantles and clamps. Angled side necks reduce interference between attached glassware and improve handling when several connections are active at the same time. The 100 ml volume is well suited to small-scale preparative work, process scouting and teaching environments that rely on durable ground-glass joints. This flask belongs to the range of round flasks and flasks with ground glass joints used throughout general chemistry laboratories.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Three-necked round-bottom flask, 100 ml, Centre neck 29/32, side neck 29/32
What is this article?
Three-necked round-bottom flask, 100 ml, Centre neck 29/32, 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.
