Description
Schlenk flask 100 ml with socket NS 14,5/23 is a single-neck laboratory vessel for inert-atmosphere and vacuum work. Made from borosilicate glass 3.3, it carries one ground joint NS 14,5/23 for connection to standard Schlenk lines and complementary glassware. A lateral PTFE valve adjustable from 0 to 3 mm permits controlled gas or vacuum access, while the 8 mm olive provides a secure hose connection. Nominal volume is 100 ml and net weight is 0,065 kg. Classed as Schlenk apparatus, the flask serves as a round-bottom, ground-joint, distillation or receiving flask for air-sensitive reactions, solvent transfers and sample isolation. This design from manufacturer Rettberg suits synthetic and organometallic laboratories that routinely perform evacuation and back-filling cycles. The compact single-neck layout keeps the assembly straightforward, and the side-arm valve supports efficient inert-gas manipulation on the bench or in a fume hood. Borosilicate glass 3.3 construction matches common laboratory requirements for chemical and thermal handling in everyday Schlenk-line practice.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Nitrogen flask, 100 ml, socket size 14,5/23, side PTFE-valve 0 - 3 mm,
What is this article?
Nitrogen flask, 100 ml, socket size 14,5/23, 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.
