Beschrijving
Flat-bottom flask with standard ground joint NS 19/26 is a 50 ml laboratory vessel manufactured from borosilicate glass 3.3 (LBG 3.3). With a nominal volume of 0,05 l, it is suited to medium-small scale reactions, sample preparation, heating, and general laboratory procedures that require a stable standing base. The NS 19/26 ground joint offers a standardised interface for condensers, distillation heads, adapters, and stoppers, enabling reliable connections in reflux, distillation, or extraction work. Borosilicate glass 3.3 delivers the thermal shock resistance and chemical durability associated with this glass type for routine bench use. This single-piece flask from manufacturer Labbox has a net weight of 0,056 kg and fits research, teaching, and analytical environments that standardise on NS 19/26 jointware. The flat bottom permits placement on hot plates or magnetic stirrers with appropriate support. Clear specification of volume, joint size, and LBG 3.3 material helps laboratories integrate the flask into existing glassware sets without mismatch.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Kookkolf, vlakke bodem, LBG 3.3, hals 19/26, 50 ml
What is this article?
Kookkolf, vlakke bodem, LBG 3.3, hals 19/26, 50 ml is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Rondbodemkolven, inside Bekerglazen & kolven, in Labmateriaal.
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.
