Description
Pycnometer Gay-Lussac 25 ml is a classic glass instrument designed for precise density and specific-gravity determination of liquids by gravimetric methods. This unadjusted model conforms to ISO 3507 and is fitted with a ground capillary stopper that defines the exact working volume through capillary overflow of excess liquid. The 25 ml nominal capacity supports accurate mass-to-volume measurements of solvents, solutions, oils and other free-flowing liquids in analytical chemistry, quality-control and educational laboratories. High-quality glass construction ensures chemical resistance, optical clarity and straightforward cleaning between runs. Available as a single unit from manufacturer Witeg, the pycnometer offers a simple, reliable and economical solution for routine density work without complex instrumentation. Its compact Gay-Lussac design minimises evaporation losses and facilitates reproducible filling to the calibration mark. Typical applications include characterisation of liquid samples where high volumetric precision is required for research, process monitoring or teaching demonstrations.

Questions about Pycnometer acc. to Gay-Lussac, unadjuste
What is this article?
Pycnometer acc. to Gay-Lussac, unadjuste 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 laboratoire.
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.
