Description
Pointed flask 10 ml NS 19/26 Economy is a clear glass laboratory flask featuring a pointed bottom and a standard ground joint NS 19/26. Manufactured from borosilicate glass 3.3, it offers the chemical resistance and thermal stability expected for everyday laboratory use. With an outer diameter of 33 mm and a height of 75 mm, the flask keeps a compact footprint while the pointed base supports efficient drainage and recovery of small volumes. The NS 19/26 joint connects to standard laboratory glassware assemblies used in synthesis, concentration, and sample handling. Supplied in packs of 10 pieces from manufacturer Witeg, these economy pointed flasks suit analytical and preparative tasks where a 10 ml working volume is practical. Clear glass enables straightforward visual inspection of contents throughout use. The balance of capacity, joint compatibility, and pointed geometry makes this flask a reliable option for research, quality-control, and teaching laboratories working with limited sample amounts.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flask pear shaped 10 ml ST 19/26 Economy
What is this article?
Flask pear shaped 10 ml ST 19/26 Economy 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.
