Description
Pointed flask 10 ml NS 14/23 is a laboratory glassware item with a conical tip intended for collection, concentration and transfer of modest liquid volumes in analytical and preparative procedures. Produced from borosilicate glass 3.3 in clear glass quality, it combines chemical resistance with thermal stability suitable for everyday laboratory heating and cooling. Nominal volume is 10 ml (0,01 l), outer diameter 33 mm and height 70 mm; a single neck with standard ground joint NS 14/23 enables reliable coupling to condensers, adapters and complementary jointed glassware. The pointed base aids complete drainage and reduces residual hold-up, which is advantageous in small-scale distillations, solvent removal and sample preparation. Packs of 10 pieces from manufacturer Witeg equip teaching, research and quality-control laboratories with consistent borosilicate performance. Clear glass construction permits continuous visual inspection of the contents, and the material withstands typical laboratory reagents and cleaning routines. Compact proportions support convenient handling under fume hoods and on busy benches while retaining the functional advantages of a pointed-bottom flask.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flask pear shaped 10 ml ST 14/23
What is this article?
Flask pear shaped 10 ml ST 14/23 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.
