Description
Pycnometer with thermometer 5 ml is a precision glass vessel for accurate density determination of liquids according to ISO 3507. It is equipped with an integrated thermometer carrying an NS 10/19 ground joint, a side capillary and a matching cap with NS 7/16 joint. The unit is adjusted and balanced to the third decimal place, and the thermometer uses organic filling. This compact 5 ml pycnometer from manufacturer Witeg supports density measurements in analytical laboratories, quality-control environments and research applications requiring small sample volumes. The side-capillary design permits controlled overflow and efficient temperature equilibration during filling and weighing. With a net weight of 0,022 kg the instrument is easy to handle on laboratory balances. It is suitable for solvents, oils, aqueous solutions and similar liquids under standard laboratory conditions. Delivered as a single piece, the adjusted pycnometer provides a ready-to-use density bottle for precise volumetric work with limited sample quantities.
This article is part of Density meters & pycnometers, in Density & viscosity measurement.

Questions about Pycnometer with thermometer, 5 ml, acc.
What is this article?
Pycnometer with thermometer, 5 ml, acc. is the article on this page. Luminix Health distributes Witeg 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.
