Description
Flat-bottom flask with narrow neck, 4000 ml, is a large-volume laboratory vessel intended for heating, mixing, dissolving and holding liquids on a stable base. The narrow neck supports more controlled pouring and reduced evaporative loss during handling, while the flat bottom provides a firm stance on the bench, hotplate or stirrer when appropriate support is used. Supplied as a pack of 2 pieces, the format suits laboratories that need spare high-capacity flasks for media preparation, buffer work or intermediate storage without purchasing bulk single units. The 4000 ml capacity accommodates larger batches and scale-up steps in teaching, quality-control and general chemistry environments. From manufacturer Dinkelberg, this item belongs to everyday laboratory material rather than specialised apparatus. Origin is the Czech Republic. Narrow-neck flat-bottom flasks remain a standard choice where vessel stability and moderate access matter more than wide-mouth convenience. The two-piece pack helps maintain ready stock of large working volumes on shared lab benches.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flask, flat bottom narrow-neck, 4000ml, 2/PK
What is this article?
Flask, flat bottom narrow-neck, 4000ml, 2/PK 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.
