Description
Gay-Lussac pycnometers in borosilicate glass 3.3 are pear-shaped vessels intended for laboratory density and specific-gravity determinations within volumetric analysis. This model features a nominal capacity of 25 ml and is delivered as one piece, providing ample volume for liquid samples when larger aliquots are preferred. The pear-shaped geometry supports controlled filling and stable placement on the analytical balance during weighing. Borosilicate glass 3.3 offers the chemical and thermal resistance associated with durable laboratory glassware. Available from manufacturer Marienfeld, the pycnometer serves density measurements, liquid characterisation, and quality-control applications in research, educational, and industrial environments. Its unit weight of 0,030 kg keeps the vessel practical for balance use despite the higher capacity. Transparent construction enables clear observation of fill level and sample appearance throughout the procedure. Laboratories that rely on Gay-Lussac-type pycnometers among volumetric flasks and vessels will appreciate this 25 ml pear-shaped unit as a robust option for density work with larger sample volumes.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Gay-Lussac Pycnometers, borosilic. glass 3.3, pear-shaped, 25 ml, 1 unit(s)
What is this article?
Gay-Lussac Pycnometers, borosilic. glass 3.3, pear-shaped, 25 ml, 1 unit(s) is the article on this page. Luminix Health distributes Marienfeld 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.
