Description
Round-bottom flask with standard ground joint NS 14/23 is a laboratory glass vessel in borosilicate glass LBG 3.3 with a nominal volume of 100 ml. The spherical body is intended for heating, mixing, distillation and collection steps where uniform heat distribution and a stable liquid surface matter. Its standardised NS 14/23 ground joint provides a compatible connection to condensers, still heads, adapters and other jointed glassware used in organic synthesis, sample work-up and teaching experiments. Made from borosilicate glass 3.3 from manufacturer Labbox, the flask belongs to the LBG product line for routine laboratory glassware. It is supplied as a pack of 12 pieces, supporting multi-station setups, parallel reactions or stock replenishment in research, education and quality-control laboratories. Typical use categories include round-bottom flasks, ground-joint flasks, distillation flasks and receiving flasks. The pack has a net weight of 0,390 kg. With a compact joint size and a practical 100 ml working volume, this flask fits everyday preparative workflows that require interchangeable NS 14/23 connections and durable borosilicate construction without unnecessary complexity.

Questions about Ballon à ébullition à fond rond, LBG 3.3, embouchure 14/23, 100 ml, 12 pièces
What is this article?
Ballon à ébullition à fond rond, LBG 3.3, embouchure 14/23, 100 ml, 12 pièces is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Ballons à fond rond, inside Béchers & fioles, in Matériel de laboratoire.
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.
