Description
Kjeldahl flask with NS ground joint neck, manufactured from borosilicate glass 3.3, is intended for nitrogen determination and related laboratory digestion work. This 500 ml version has a white inscription for easy reading and a female ground joint NS29/32 on the neck, allowing reliable coupling to condensers, adapters, and other standard joint glassware. Borosilicate 3.3 provides the thermal shock and chemical resistance needed for routine wet chemistry and Kjeldahl protocols. Offered as a pack of 2 pc(s) from manufacturer Hecht, the flask fits analytical and teaching laboratories that use standardized jointed apparatus. Defined 500 ml capacity, durable Boro 3.3 construction, and the NS29/32 joint together support stable setups for digestion, distillation, and sample preparation whenever a clearly marked, robust Kjeldahl flask is required.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flasks, Kjeldahl with socket, Boro 3.3, Capacity: 500 ml, Socket: NS29/32
What is this article?
Flasks, Kjeldahl with socket, Boro 3.3, Capacity: 500 ml, Socket: NS29/32 is the article on this page. Luminix Health distributes Hecht 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.
