Description

Pointed flask 250 ml with NS 14/23 ground joint is a laboratory vessel made from heat-resistant, durable borosilicate glass in accordance with DIN standard 12383. Thick walls, a heavy base and a reinforced rim help prevent breakage during cleaning and transport. Perfectly ground NS necks with a smooth interior provide a reliable, leak-tight seal when connected to matching joints. White enamel markings remain clearly legible under normal laboratory use. This pointed flask from manufacturer ISOLAB Laborgeräte is well suited to evaporation, concentration and crystallisation work, where the conical tip supports complete recovery of small residual volumes. The 250 ml capacity and standard NS 14/23 joint integrate readily with condensers, adapters and other common ground-joint glassware. Robust construction and dimensional stability of the joint make the flask appropriate for repeated analytical and preparative procedures that demand dependable thermal and mechanical performance in everyday laboratory practice.

This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about flask - pear shape - socket : NS 14/23 - 250 ml

What is this article?

flask - pear shape - socket : NS 14/23 - 250 ml is the article on this page. Luminix Health distributes ISOLAB 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.
