Description
Schlenk flask 1000 ml with socket NS 29/32 is a single-neck laboratory vessel fitted with a lateral PTFE valve adjustable from 0 to 3 mm and an 8 mm olive. Produced from borosilicate glass 3.3, it belongs to the Schlenk apparatus family and serves as a round-bottom, ground-joint, distillation or receiving flask. The precision ground joint ensures leak-tight connections in vacuum or inert-gas systems, while the side PTFE valve permits accurate regulation of gas flow or vacuum via the olive. Nominal volume reaches 1000 ml and net weight is 0,316 kg. The configuration is well suited to larger-scale handling of air-sensitive reagents in synthetic chemistry. Offered as a single unit and manufactured in Germany under the Rettberg ® trademark, the flask from manufacturer Rettberg delivers the chemical durability and thermal stability expected of borosilicate glass 3.3 together with convenient valve control for routine Schlenk-line operations. Its sturdy build supports repeated use in research and preparative laboratories that rely on high-quality ground-joint glassware.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Nitrogen flask, 1000 ml, socket size 29/32, side PTFE-valve 0 - 3 mm,
What is this article?
Nitrogen flask, 1000 ml, socket size 29/32, side PTFE-valve 0 - 3 mm, is the article on this page. Luminix Health distributes Rettberg 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.
