Description
Round-bottom flask, narrow neck, 20000 ml is a large-volume laboratory vessel for heating, reaction and distillation work where a spherical body supports even heat distribution and efficient mixing. The narrow-neck (Enghals) design helps limit evaporative losses, simplifies stoppering and supports secure clamping in stands or heating mantles during prolonged procedures. With a nominal capacity of 20000 ml, the flask is suited to bulk solvent handling, preparative chemistry, recovery steps and teaching or industrial workflows that need high working volume in a classic round-bottom format. It is offered as a single piece from manufacturer Dinkelberg and originates from the Czech Republic, placing it among standard laboratory materials used in research, quality control and production support labs. The simple geometry integrates readily into common glassware assemblies without specialised fittings being specified for this variant. Laboratories choosing this 20000 ml narrow-neck round-bottom flask obtain a straightforward high-capacity option for routine setups that call for durable, easy-to-position glassware with a conventional Enghals profile and clear volumetric designation for inventory and method documentation.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flask with round bottom, narrow-neck, 20000ml
What is this article?
Flask with round bottom, narrow-neck, 20000ml is the article on this page. Luminix Health distributes Dinkelberg 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.
