Refractometer: What do they measure?
The refractometer is an optical device that serves to measure the percentage of soluble solids in a liquid solution, this instrument uses the physical principle of total refraction of light, which originates from the concentration and type of substance dissolved in a liquid solution.
How is Food Analyzed with the Refractometer?
The refractometer is an instrument that is used in laboratories to obtain sugar levels, sodium chloride, degrees Brix expressed in percentage (%), fructose, glucose in syrups, oils, juices, among others. This new equipment calculates the refractive index of light passing through the sample and correlates the values in scales, demonstrating that a certain amount dissolves in it, and converts it to dense, and its optical properties are altered, all this corresponds to the speed at which light passes through the substances and determines how much is refracted or bent.
How do I read the Refractometer?
The refractometer is an optical laboratory instrument designed to measure sugar, alcohol or salt content in Brix, depending on the type of sample. This type of measurement is usually applied in the food and beverage industries, among others., and constitutes the determination of sucrose in water, where 1gr Brix, is equal to 1gr sucrose / 100g solution.
Use of Micropipettes in Blood Tests
Micropipettes are small portable devices that can be used to measure and transfer small amounts of fluid. They are often used in laboratories to transfer small volumes of fluids, such as DNA, RNA, and blood samples. As micropipettes are increasingly used in blood tests, it is important to understand how they work and how they can be used effectively.
How can Pipettes be used to Transfer Liquids?
Pipettes are a very useful tool for transferring liquids from one container to another. They can be used to transfer liquids from one bottle to another, or to transfer liquids from one test piece to another. Also to take fluid samples for analysis.
Copper Ion Meters for Pool Disinfection
In recent years the use of chlorine for swimming pool disinfection has been replaced by ionization with copper or with the combination of copper and silver. This procedure is performed with copper ionizers. These devices use electrolysis to release copper ions into pool water, via an anode or electrode that is usually connected to the pipe that supplies water to the pool. These devices can be powered by a power supply or use solar panels to generate electricity.
Food Analysis Using the Potassium Ion Meter
The potassium meter is a portable, safe and easy-to-use device. This device is essential for laboratory professionals and field technicians. This tool allows food quality records and provides a quick estimate of potassium concentration in foods from many applications.
Functions of pH Ion Meters in the Cosmetic Industry
In the manufacture of cosmetic products there are three essential aspects that must be addressed, the first, the elaboration of products pleasant to the touch and to the smell. The second is that they are efficient, that is, that these products improve the condition of the skin or hair and do not cause unfavorable effects. The third, that the shelf life declared on the packaging is met.
What are the characteristics of an ion meter?
An ion meter is an electrochemical analytical device that is used to measure ion concentration in a solution. It is used with several ion electrodes (ISE).
The ion meters: what are they used for?
An ion meter is a device used in laboratories and industries to measure the concentration of ions in a solution, by using ion electrodes (ISE) thanks to its electrochemical activity. An ion selective electrode (ISE) is a kind of sensor that allows ion testing in various types of samples. The process that these electrodes work with is ion exchange, which measures the potential difference that is produced by the contact of the electrode with the ion being determined.
