It does not store any personal data. This should give a reading of zero; clean and calibrate the device if this value is not obtained. Step 3: Place a small amount of the solution to be tested onto the prism. A couple of drops is enough. Step 4: Look through the eyepiece while you point the prism toward a light source. Do not look at the sun. Step 5: Focus the eyepiece, and take a reading where the base of the blue color meets the scale.

Use a digital refractometer for an easier and more accurate measurement that will increase the productivity of your lab and save time and money.

In general, the terms degrees Brix , degrees Plato and degrees Balling are all interchangeable. All three scales express the weight percentage of sugar solutions and relate this weight to specific gravity.

Specific gravity relates the weight of a given volume of liquid to the same volume of water. Liquids heavier than water like must or wort have a specific gravity greater than 1. Liquids lighter than water, such as alcohol, have a specific gravity less than 1. The oldest scale, Balling, was established in A bit later Brix corrected some of the calculation errors in the Balling scale and introduced the Brix table. Essentially, they are the same. The tables differ in their conversion from weight percentage to specific gravity in the fifth and sixth decimal places of the specific gravity scale.

HFCS is used to replace sucrose in the beverage and food industries. As a sweetener, HFCS is often compared to granulated sugar, but manufacturing advantages of HFCS over sugar include its ease of handling and cost-effectiveness. With both methods, the results obtained are identical when measuring pure sucrose or pure HFCS and can be compared with each other.

A Brix acid ratio is the ratio of the degrees Brix of the juice to the grams of anhydrous citric acid per grams of the juice. It is one of the most commonly used indicators of juice quality as well as fruit maturity. Then, make sure your method is set to measure Brix at your desired temperature. Add approx.

The following table shows Brix measurement results for a variety of samples measured once with a Density meter and a Refractometer So which method is the correct one? Sample Brix by density Brix by refrac. Top of page. Download our free application note. Type of Instrument. Hydrometer, learn how to choose it, the definition, advantages and more.

Main Applications. Quick checking of Brix by density value in quality control laboratories Suitable for repeated measurements of similar kinds of samples wine, beer, juices due to the limited measuring range Not suitable for expensive samples large volume required.

Learn how to choose, use and calibrate hydrometers. Simple, inexpensive Quick check of an approximate value. User-dependent results Takes a long time for temperature equilibration Small measuring range, typically takes 20 hydrometers to cover a wide measuring range Large sample volume required mL to mL Difficult to clean Breakable.

When light enters a liquid it changes direction; this is called refraction. Refractometers measure the degree to which the light changes direction, called the angle of refraction.

A refractometer takes the refraction angles and correlates them to refractive index nD values that have been established. Using these values, you can determine the concentrations of solutions. For example, solutions have different refractive indexes depending on their concentration in water.
