Description
Evaporating flask 12 ml NS 14/23 flat bottom is a pear-shaped laboratory vessel intended for small-scale rotary evaporation and concentration tasks. Made from clear borosilicate glass 3.3, it provides the chemical resistance and thermal performance expected in modern laboratories. The nominal volume of 12 ml together with the standard ground joint NS 14/23 ensures a secure fit to rotary evaporators and compatible glassware. Its flat-bottom design offers stable standing on the bench when not mounted and still supports efficient heat transfer during operation. This evaporating flask from manufacturer Witeg is supplied as a single piece, ideal for specialised or low-volume applications in organic synthesis, analytical chemistry and pharmaceutical research. The pear profile facilitates thorough drainage and easy cleaning after use. With a net weight of only 0,016 kg the flask is lightweight yet durable under typical laboratory conditions. It is particularly useful for micro-scale solvent removal, concentration of limited sample amounts and other evaporation work requiring precise joint sealing and small working volumes.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Evaporating flask 12 ml ST 14/23 flat bottom
What is this article?
Evaporating flask 12 ml ST 14/23 flat bottom 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.
