What is a hand refractometer used for?
What is a hand refractometer used for?
A traditional handheld refractometer is an analog instrument for measuring a liquid’s refractive index. It works on the critical angle principle by which lenses and prisms project a shadow line onto a small glass reticle inside the instrument, which is then viewed by the user through a magnifying eyepiece.
What is a refractometer and what is it used for?
Optical methods The refractometer is a well-established instrument used for measuring the water content of liquids. It measures the refractive index of the liquid, which changes according to the moisture content.
What are the two most common uses of the refractometer?
Types of refractometers In laboratory medicine, a refractometer is used to measure the total plasma protein in a blood sample and urine specific gravity in a urine sample. In drug diagnostics, a refractometer is used to measure the specific gravity of human urine.
What are the advantages of using a refractometer?
Refractometry brings several benefits as an analytic modality: Instruments are simple and relatively inexpensive, measurement is rapid, and quantitation is highly accurate. On the negative side, refractometry brings value only when the constituents of a solution are well-known.
How does an alcohol refractometer work?
How a Refractometer Works. A refractometer is an optical device that, like a hydrometer, measures the specific gravity of your beer or wort. It does so by sampling a small amount of liquid, and looking at its optically. The main advantage over a hydrometer is the small sample size needed – typically only a few drops.
What are the uses of refractive index?
Every material that interacts with light has a refractive index. In many industries, a refractive index measurement is used to check the purity and concentration of liquid, semi-liquid and solid samples. Liquids and semi-liquid samples can be measured with high accuracy (e.g. down to – / + 0.00002).
What are the applications of refractive index?
Generally it is used to measure the concentration of a solute in an aqueous solution. For a solution of sugar, the refractive index can be used to determine the sugar content (Brix degree). It can be used also in determination of drug concentration in pharmaceutical industry.
What is meant by refractometer?
: an instrument for measuring refractive indices (as for identification or the determination of sugar content)
