Refractometer FAQs What is a Refractometer? A refractometer is a simple instrument used for measuring concentrations of aqueous solutions such as gases, liquids, and translucent solids. Different types of refractometers are available depending on the application. Refractometers can be handheld, compact, benchtop, Abbe, and Brix as well as different .The appropriate cutoff point for Brix and STP refractometers and the transmission infrared (TIR) spectroscopy method was determined for low IgG concentrations (< 10 g/L). Serum samples were collected from alpacas (N = 169) and tested by both refractometers. The correlation between Brix % and STP was high [correlation coefficient (r) = 0.99 .
A Refractometer works because light travels at different velocities in different mediums, the light beam is bent at the interface between two adjoining materials.This is called “refraction”. There is an angle of light propagation at which refraction no longer occurs, the light beam instead being reflected back into the original material.Data on various species compiled and adapted in part from multiple sources, including Latimer KS, Duncan & Prasse’s Veterinary Laboratory Medicine: Clinical Pathology, 5th ed., Wiley-Blackwell, 2011; and Kaneko JJ, Harvey JW, Bruss ML, Clinical Biochemistry of Domestic Animals, 6th ed., Academic Press, 2008.Reference ranges vary between laboratories. Refractometers can be used to accurately measure the alcohol content of beer up to 20% ABV (alcohol by volume). Specific Features to Look for When Buying a Refractometer. When it comes to selecting a refractometer, there are a number of specific features to consider. Accuracy is likely the most important factor to consider when selecting any .
Refractometers are specialist environmental test and measurement devices used to measure the angle of refraction - the extent to which light changes direction when passing through a translucent substance such as an aqueous solution. Refractometry is a widely used technology because this angle can be used to accurately assess the concentration of any . Some refractometers contain a scale that estimates serum total protein in g/dL. If using this type of refractometer, a value greater than 5.5 g/dL is an indication that the calf absorbed adequate IgG from the colostrum. Other refractometers will have a scale for measuring %Brix. These refractometers are also commonly used to measure colostrum . This refractometer is designed for measuring sugar content in sugary liquids such as fruit juice, honey, maple syrup and other . The 0-80% large scale range makes it be suitable in wider field. This refractometer is almost equivalent to a regular brix plus a honey refractometer, but you just need to spend about half money.
