Description
Pycnometer Gay-Lussac 50 ml is an unadjusted glass density vessel manufactured to ISO 3507 and equipped with a precision ground capillary stopper. The classic Gay-Lussac geometry allows accurate determination of liquid density by mass difference after temperature equilibration. With a nominal capacity of 50 ml and a net weight of 0,036 kg, the instrument is supplied as a single piece ready for laboratory calibration. The ground capillary stopper ensures overflow of excess liquid and a reproducible meniscus, supporting high-precision weighing on analytical balances. Produced by Witeg, this pycnometer is intended for routine densitometry, quality-control checks and research applications in analytical chemistry, materials science and process laboratories. Because the vessel is supplied unadjusted, the exact internal volume is established by the user with a reference liquid of known density, guaranteeing traceability to local standards. The robust borosilicate construction withstands repeated thermal cycling in water baths while the capillary design minimises evaporation losses during handling. Ideal for density measurements of solvents, oils, aqueous solutions and other free-flowing liquids, the 50 ml Gay-Lussac pycnometer remains a fundamental tool for physical-property characterisation.
This article belongs on Density meters & pycnometers, in Density & viscosity measurement.

Questions about Pycnometer Gay-Lussac 50 ml
What is this article?
Pycnometer Gay-Lussac 50 ml is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Density meters & pycnometers, inside Density & viscosity measurement, in Instruments de précision.
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.
