Description
Pear shape flasks, DURAN®, with standard ground joint 19/26 and a nominal capacity of 100 ml are laboratory glass vessels for preparative and analytical work where a pear-shaped body and a defined conical joint are required. The pear profile concentrates liquid toward the base, which supports small working volumes, controlled heating, and efficient recovery of residues after evaporation or reaction steps. The standard ground joint 19/26 provides a reproducible connection to condensers, adapters, stoppers, and other jointed glassware in common laboratory assemblies. Supplied as a single piece, each flask is a compact unit suited to bench-scale setups, teaching laboratories, and routine synthesis or distillation trains. These pear shape flasks from manufacturer Lenz are offered under the DURAN® designation and fall within the category of round flasks and flasks with ground glass joints used across general labware applications. Unit quantity is 1 pc, with a stated weight of 0,049 kg per piece, supporting clear identification for inventory and workstation planning. The combination of pear geometry, 100 ml capacity, and NS 19/26 joint makes the item a practical choice whenever a small pear flask with a mid-size ground joint is specified in a method or apparatus list.
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 19/26, 100 ml, 1 unit(s)
What is this article?
Pear shape flasks, DURAN®, standard ground joint 19/26, 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.
