Description
Round-bottom flask 50 ml with standard ground joint NS 29/32 is a precision laboratory vessel intended for distillation, reaction and collection duties. Manufactured from borosilicate glass 3.3, the flask is fitted with a short neck and a female ground socket of size NS 29/32 according to DIN EN ISO 4797. This larger joint size provides robust, interchangeable connections to matching condensers and adapters. The product from manufacturer Marienfeld offers high chemical durability together with good thermal-shock resistance for routine laboratory heating and reflux operations. Its nominal volume of 50 ml is ideal for small-scale synthetic and analytical procedures, while the spherical shape promotes uniform heating in mantles or baths. Supplied in cartons of 10 pieces, the flasks are immediately ready for use. They serve effectively as round-bottom flasks, ground-joint flasks, distillation flasks and receiving flasks across organic chemistry, sample preparation and solvent-recovery workflows that require accurate joint dimensions and dependable glass performance under standard laboratory conditions.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

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.
