Description
Pycnometer according to Gay-Lussac, 100 ml, calibrated is a pear-shaped laboratory vessel intended for precise density determination of liquids. Fabricated from borosilicate glass 3.3 and fitted with a ground glass stopper, the instrument conforms to DIN ISO 3507 requirements for pycnometers. The calibrated nominal volume of 100 ml, equivalent to 0,1 l, supports accurate specific gravity and density measurements in analytical chemistry. Its classic Gay-Lussac design facilitates convenient filling, temperature equilibration and weighing steps typical of pycnometric procedures. Chemical resistance and thermal stability of borosilicate glass 3.3 make the vessel suitable for repeated use with a wide range of aqueous and organic liquids. Packaged as two pieces, this calibrated pycnometer is offered by manufacturer Marienfeld for research, quality-control and educational laboratories that require reliable volumetric glassware. The ground stopper provides a secure closure during handling and measurement cycles, helping maintain volumetric integrity throughout density assays. The pear-shaped body promotes complete drainage and reproducible filling for consistent results across successive determinations.
This article is part of Density meters & pycnometers, in Density & viscosity measurement.

Questions about Specific gravity bottles, 100 ml, calibrated
What is this article?
Specific gravity bottles, 100 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.
