Beschrijving
Evaporating flask 250 ml with standard ground joint NS 29/32 is laboratory glassware for rotary evaporators and related evaporation equipment. The vessel offers a 250 ml working volume and uses the widely established NS 29/32 joint as standard, giving a secure fit to compatible evaporator assemblies, condensers, and receiving setups. On request the same flask design is also available with ground joint NS 24/29, so laboratories can match alternative system configurations without changing capacity. This evaporating flask from manufacturer Heidolph is intended as a replaceable or supplementary vessel for concentration, solvent recovery, and sample preparation in chemical, pharmaceutical, and research workflows. Supplied as one piece per pack and with a net weight of 0,120 kg, the 250 ml format suits small- to medium-scale evaporations where controlled volume and a reliable ground-glass interface matter. It belongs to the accessory range for evaporation instruments and supports day-to-day distillation and concentration tasks on stations that specify NS 29/32 connections. Choose this capacity when moderate batch sizes and standard joint geometry are required for routine laboratory evaporation work.
This article is part of Evaporating dishes, in Dishes, crucibles & porcelain.

Questions about Evaporating flask 250 ml -- NS 29/32
What is this article?
Evaporating flask 250 ml -- NS 29/32 is the article on this page. Luminix Health distributes Heidolph for laboratory use. It sits in Evaporating dishes, inside Dishes, crucibles & porcelain, in Labmateriaal.
An evaporating dish is a shallow porcelain or glass dish used to drive off a liquid over heat. The flat form gives surface area. Porcelain takes a higher heat than borosilicate. It is not a crucible and it is not a volumetric vessel.
A dish is an open vessel for drying, evaporating or holding a solid. Porcelain and glazed ceramic take a higher temperature than borosilicate glass, which is why a crucible, not a beaker, goes into a furnace. A watch glass covers, or holds a small amount for drying. A mortar is for grinding. The temperature and the chemical, not the shape alone, choose the material. Laboratory ware of this family is listed under ISO laboratory ware.
