Description
Flat-bottom flask 1,000 ml with standard ground joint is a laboratory vessel manufactured from borosilicate glass 3.3 and fitted with an NS 29/32 socket. Designed with a short neck according to DIN EN ISO 4797, it offers excellent chemical resistance and thermal stability for routine heating, boiling and reaction work. The nominal volume of 1 l provides ample capacity for medium-scale preparations while the flat base ensures secure standing on hotplates or benches. Supplied in cartons of 10 pieces from manufacturer Marienfeld, these flasks are ideal for general chemistry, sample digestion and distillation setups where a robust, reusable glass container with a standardised ground joint is required. The borosilicate 3.3 material withstands typical laboratory temperature changes and aggressive media, making the flask a reliable choice for both teaching and research environments. Clear wall thickness and precise joint dimensions support leak-free connections to condensers, adapters and other ground-joint glassware.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Boiling flasks 1.000 ml with round bottom and ground joint
What is this article?
Boiling flasks 1.000 ml with round bottom and ground joint is the article on this page. Luminix Health distributes Marienfeld 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.
