Description
Flat-bottom flask 50 ml with standard ground joint is a compact laboratory vessel equipped with a socket NS 24/29 and short neck. Fabricated from borosilicate glass 3.3 according to DIN EN ISO 4797, it provides a nominal volume of 0,05 l suitable for small-scale reactions, sample preparation or storage on the bench. The flat base allows stable standing without additional supports, while the ground joint ensures secure, interchangeable connections to condensers, stoppers or adapters. Supplied in packs of 10 pieces packed in cartons from manufacturer Marienfeld, these flasks streamline routine laboratory workflows. Borosilicate glass 3.3 confers good resistance to chemical attack and thermal stress, supporting repeated autoclaving or heating cycles under normal conditions. Short-neck construction simplifies handling and minimises hold-up volume. Compliance with DIN EN ISO 4797 guarantees dimensional accuracy and compatibility within standardised glassware systems used for synthesis, titration or general analytical work.

Questions about Boiling flasks 50 ml with round bottom and ground joint
What is this article?
Boiling flasks 50 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.
