Description
Distillation flask 250 ml with side arm 200/8 mm is a laboratory flask for distillation, separation and purification work. It has a nominal volume of 0,25 l and is manufactured from DURAN® tubing, providing the chemical and thermal resistance expected of quality borosilicate glassware. Principal dimensions are a flask diameter of 85 mm, overall height of 200 mm and neck diameter of 34 mm; the integrated side arm is specified as 200/8 mm for convenient connection to condensers, adapters or receiving apparatus. Supplied in packs of 10 pieces from manufacturer Witeg, the flask supports organic synthesis, solvent recovery, essential-oil isolation and analytical sample preparation under atmospheric or reduced-pressure conditions when used with suitable heating and vacuum equipment. The DURAN® construction maintains dimensional stability through repeated thermal cycling. Net weight is 0,118 kg. This item fits the range of round-bottom, ground-joint, distillation and receiving flasks routinely used in teaching laboratories and research facilities that require reliable glassware for separation workflows.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Distilling flasks 250 ml with side arm 200/8 mm
What is this article?
Distilling flasks 250 ml with side arm 200/8 mm is the article on this page. Luminix Health distributes Witeg 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.
