Description
Pear shape flasks, DURAN®, with standard ground joint 29/32 and a nominal capacity of 100 ml are laboratory glass vessels intended for work that needs a pear-shaped body together with a larger conical joint. The pear form keeps liquid toward the lower section of the flask, which is useful for modest sample volumes, gentle concentration steps, and recovery of material after heating or solvent removal. The standard ground joint 29/32 mates with matching condensers, still heads, adapters, and stoppers in jointed glass apparatus. Each item is supplied as one piece, giving a clear single-unit pack for bench use, method setup, or replacement stock. These pear shape flasks from manufacturer Lenz carry the DURAN® designation and belong to the group of round flasks and flasks with ground glass joints used in everyday laboratory glassware. Unit quantity is 1 pc, and the stated weight is 0,066 kg per piece, which helps with handling and storage planning. With 100 ml capacity and an NS 29/32 joint, the flask suits assemblies that specify a small pear flask paired with a wider standard ground joint for secure, leak-resistant connections in preparative or analytical workflows.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Pear shape flasks, DURAN®, standard ground joint 29/32, 100 ml, 1 unit(s)
What is this article?
Pear shape flasks, DURAN®, standard ground joint 29/32, 100 ml, 1 unit(s) is the article on this page. Luminix Health distributes Lenz 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.
