Description
Round-bottom flask with standard ground joint, LBG 3.3, NS 19/26, 500 ml is a laboratory vessel made from borosilicate glass 3.3 for synthesis, distillation and collection work. The spherical body is fitted with a precision NS 19/26 ground joint so that condensers, adapters and other standard ground-joint components can be connected securely for reflux, vacuum or atmospheric operation. Its nominal volume of 500 ml (0,5 l) suits medium-scale preparative chemistry, while the rounded base promotes even heat distribution when used with heating mantles or baths. Net weight is 0,174 kg. Offered as a single piece from manufacturer Labbox under the LBG product line, the flask belongs to the familiar categories of round-bottom, ground-joint, distillation and receiving flasks. Clear borosilicate glass 3.3 allows continuous visual monitoring of boiling, colour changes and phase behaviour. Typical uses include organic reactions under reflux, solvent recovery, fraction collection and general laboratory heating or cooling procedures where reliable NS 19/26 glassware is required.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Boiling flask round bottom, LBG 3.3, mouth 19/26, 500 ml
What is this article?
Boiling flask round bottom, LBG 3.3, mouth 19/26, 500 ml is the article on this page. Luminix Health distributes Labbox 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.
