Description
Powder flask 500 ml with NS 29/32 ground joint is a larger DURAN® laboratory flask for storing and transferring substantial quantities of powdered reagents and dry solids. The wide NS 29/32 joint eases filling from scoops or funnels and pairs with standard stoppers and adapters used in jointed glass apparatus. Provided as one piece weighing 0,186 kg, it supports preparative chemistry, bulk sample handling, and teaching demonstrations that require a dedicated powder vessel rather than a narrow-neck flask. Manufactured by Lenz in DURAN® glass, the flask combines clear visibility of contents with the joint geometry laboratories rely on for secure connections. The 500 ml capacity is practical when working with larger solid charges, intermediate storage of dried products, or repeated dispensing into smaller vessels. Deploy it wherever a robust powder flask with a defined NS 29/32 opening streamlines solids workflow and keeps powdered materials accessible yet compatible with the rest of the ground-glass setup.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Powder flasks 500 ml, 29/32, DURAN®, 1 unit(s)
What is this article?
Powder flasks 500 ml, 29/32, DURAN®, 1 unit(s) is the article on this page. Luminix Health distributes Lenz 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.
