Description
Pycnometer according to Gay-Lussac, 25 ml, adjusted is a pear-shaped density determination vessel made from borosilicate glass 3.3. It is fitted with a ground glass stopper and manufactured in accordance with DIN ISO 3507 for accurate volumetric work. The nominal volume of 25 ml supports precise density and specific-gravity measurements of liquids in analytical laboratories. Supplied in packs of two pieces from manufacturer Marienfeld, the instrument is ready for routine quality-control, research and teaching applications. The borosilicate glass 3.3 construction offers good chemical resistance and thermal stability during weighing and temperature-equilibration steps. Its classic Gay-Lussac design with ground joint stopper ensures a reliable seal, helping maintain measurement integrity throughout the determination process. This adjusted pycnometer provides a standardised solution for laboratories that require reproducible pycnometric results according to recognised norms.
This article is part of Density meters & pycnometers, in Density & viscosity measurement.

Questions about Specific gravity bottles, 25 ml, calibrated
What is this article?
Specific gravity bottles, 25 ml, calibrated is the article on this page. Luminix Health distributes Marienfeld for laboratory use. It sits in Density meters & pycnometers, inside Density & viscosity measurement, in Lab instruments.
A pycnometer is a vessel of known volume that is weighed full. An oscillating density meter infers density from how a tube vibrates when it is filled. Both need temperature control. Air bubbles are the ordinary error.
Density is mass divided by volume. A hydrometer floats at a depth that depends on the density of the liquid. A pycnometer is a vessel of known volume that is weighed full. Viscosity is the resistance to flow. A capillary viscometer times how long a volume takes to fall through a tube. Both measurements need a stated temperature, because liquids change density and viscosity as they warm. The units trace to the BIPM and to NIST.
