Description
Pointed flask 5 ml NS 14/23 is a small-volume laboratory flask with a tapered base, suited to micro-scale reactions, distillations and sample concentration where residual volumes must be minimised. Fabricated from clear borosilicate glass 3.3, it provides chemical resistance and thermal stability for routine laboratory use. The nominal volume is 5 ml (0,005 l) and the single neck carries a standardised NS 14/23 ground joint for connection to condensers, adapters or other glassware. External diameter is 22 mm and overall height is 64 mm, giving a compact footprint that fits common heating blocks and small clamps. This pointed flask from manufacturer Witeg is supplied as clear glass, allowing easy observation of contents and meniscus. The pointed geometry concentrates the last drops of liquid at the tip, which is advantageous for quantitative transfers and recovery of precious samples. Pack size is 10 pieces, supporting convenient replenishment in synthesis, analytical and teaching laboratories that regularly handle small volumes.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flask pear shaped 5 ml ST 14/23
What is this article?
Flask pear shaped 5 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.
