Lactometer, a cylindrical vessel made by blowing a glass tube. The instrument is graduated into a hundred parts. Lactometer is a device used for finding the purity of a milk sample. Define lactometer. The lactometer consists of a long graduated test tube with a cylindrical bulb with the graduation ranging from 15 at the top to 45 at the bottom. In lactometer the point up to which it sinks in the pure milk is marked after that put in water and marked at the point up to which it sinks in water. It is a special type of Hydrometer used only for milks Principle of working : Archimedes's principle. An early description of a hydrometer comes from a Latin poem, written in the 2nd century AD by Remnius, who compared the use of a hydrometer to the method of fluid displacement used by Archimedes to determine the gold content of Hiero II's crown.. Hypatia … According to the hydrostatic law, when an object is immersed in a liquid, a buoyant force acts on it. This principle states that any substance which is submerged partially, or completely, in a fluid, is acted upon by an upwards force. Amount of solids necessary. Dew point is the temperature at which a sample of moist air (or any other water vapor) at constant pressure reaches water vapor saturation. The liquids will rise/fall inside the tube depending upon the pressure and depth. Specifically— An instrument used in measuring the volume of cream in a sample of milk, and the probable amount of water, if any, which has been added to it. Answer: One form of hydrometer is a lactometer, an instrument used to check the purity of milk. It works on the principle of floatation. Answer . If soils with less than 20% of the above compounds are to exist, pre … The hydrometer probably dates back to the Greek philosopher Archimedes (3rd century BC) who used its principles to find the density of various liquids. The principle behind the working of hydrometers is based on the Archimedes principle, or the principle of flotation. The lactometer is based on the principle that a freely floating body displaces a quantity of liquid of the same weight as the floating body and that density of a solution depends on its total solids content. If the specific gravity of a sample of milk is within the approved ranges, the milk is pure. The lactometer is a special type of hydrometer.
