Description
Rotilabo® flat bottom flask is a laboratory vessel with a standard ground joint, offered here in a 250 ml capacity with NS 45/40 joint size. The flat base supports stable placement on the bench during preparation, holding, or connection work, while the ground joint enables defined coupling to matching glassware components in jointed assemblies. This configuration belongs to the familiar range of round flasks and flasks with ground glass joints used across general laboratory practice. Packaged as 10 pc(s), the set helps standardise glassware stocks where several identical 250 ml flasks with NS 45/40 joints are required at once. The Rotilabo® line from manufacturer ROTH SELECTION presents a clear volume and joint specification so apparatus layouts remain consistent between workstations. Listed pack weight is 1,700 kg. Joint sizing and nominal capacity are stated explicitly to simplify selection beside other flat-bottom and ground-joint flasks in the same series.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Rotilabo®flat bottom flask, w. stand. ground joint, 250 ml, NS 45/40, 10 unit(s)
What is this article?
Rotilabo®flat bottom flask, w. stand. ground joint, 250 ml, NS 45/40, 10 unit(s) is the article on this page. Luminix Health distributes Carl Roth 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.
