Beschrijving
Flat-bottom flask with standard ground joint NS 19/26 is a laboratory standing flask made from borosilicate glass LBG 3.3 with a nominal volume of 50 ml. The flat base provides stable placement on the bench or heating surface, while the standardised NS 19/26 joint allows secure, interchangeable connection to condensers, adapters, stoppers and other jointed glassware. Borosilicate glass 3.3 is widely used for everyday wet-chemistry work because of its thermal and chemical resistance relative to ordinary soda-lime glass. This pack contains 12 pieces, supporting parallel setups, teaching practicals and convenient stock replenishment in research, quality-control and educational laboratories. The vessels are produced in LBG 3.3 quality from manufacturer Labbox and suit general laboratory tasks such as reactions, sample handling and simple distillation or reflux arrangements when paired with matching ground-joint accessories. Nominal volume is 0,05 l; pack net weight is 0,680 kg. Clear glass construction aids visual monitoring of contents during routine procedures.
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, 12 stuks
What is this article?
Kookkolf, vlakke bodem, LBG 3.3, hals 19/26, 50 ml, 12 stuks 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.
