High precision: The pycnometer is equipped with a tight lid, and excess sample material can overflow from the central vent hole to ensure the accuracy of measurement results. The measurement error is within 1 mg (0.001%) High quality: stainless steel material, good smoothness, effectively prevents liquid from adhering to the cup wall. The cup body is made of high-quality stainless steel and is protected from light inside and outside. Calculation method of density of pycnometer: P=(m2-m1)/v1; m1——weight of empty pycnometer (g), m2——total weight of sample and pycnometer (g), V1——volume of pycnometer ( g) Cylindrical design: The pycnometer is designed in a cylindrical shape with a large opening for easy use and cleaning. The pycnometer should be cleaned and dried immediately after use. Widely used: used to determine the density/specific gravitys of liquid paints, varnishes, test coatings, auxiliary materials, oils and other liquids at specified temperatures.
