Description
Schlenk flask 500 ml with socket NS 14,5/23 is a single-neck laboratory vessel designed for inert-atmosphere and vacuum operations. Produced from borosilicate glass 3.3, it is fitted with one ground joint NS 14,5/23 for secure coupling to Schlenk lines and matching glassware. A lateral PTFE valve adjustable between 0 and 3 mm allows precise gas or vacuum metering, complemented by an 8 mm olive for hose attachment. Nominal volume is 500 ml and net weight is 0,189 kg. Belonging to the Schlenk apparatus category, the flask can be used as a round-bottom, ground-joint, distillation or receiving flask during air-sensitive reactions, solvent transfers and product isolation. This version from manufacturer Rettberg supports synthetic chemistry groups that perform frequent evacuation and inert-gas refill cycles. The single-neck arrangement remains practical at larger scale, and the side-arm valve facilitates efficient atmosphere control. Borosilicate glass 3.3 meets standard laboratory expectations for chemical and thermal performance in everyday Schlenk-line use.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Nitrogen flask, 500 ml, socket size 14,5/23, side PTFE-valve 0 - 3 mm,
What is this article?
Nitrogen flask, 500 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.
