Description
Pointed flask 25 ml with two necks MH + SH NS 14/23 angled is a compact multi-neck laboratory vessel for small-scale reactions, distillations and sample concentration. Fabricated from clear borosilicate glass 3.3, it offers chemical durability and thermal stability suited to controlled heating. The centre neck and the angled side neck both carry standard ground joints NS 14/23, enabling simultaneous connection of condensers, dropping funnels, thermometers or gas inlets. Outer diameter is 43 mm and height 90 mm, keeping the assembly space-efficient on the bench or in a small heating bath. The pointed base aids complete drainage of the 25 ml nominal volume and reduces product loss during transfer. Supplied as a single piece from manufacturer Witeg, this two-neck design supports flexible set-ups in organic synthesis, micro-scale work and analytical sample preparation where dual access and a tapered bottom are advantageous.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flask pear shaped 25 ml two necks CN + SN ST 14/23
What is this article?
Flask pear shaped 25 ml two necks CN + SN 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.
