CONTACT MISCOThe Abbe refractometer is a classic optical instrument used to measure the refractive index of liquids or solids. Abbe refractometers are routinely used in modern chemistry labs for . accurate, requires little maintenance or calibration, uses small sample volumes, is easy to use, and lasts indefinitely with reasonable care. It is aCalibrating the instrument The calibration of all Abbe 60 refractometers can be adjusted to accurately set the scale relative to a test piece with known refractive index. This adjustment should only need to be made at infrequent intervals, but it is recommended that the test piece be applied as a daily routine to check that all is in order and .%PDF-1.5 %âãÏÓ 21 0 obj > endobj 38 0 obj >/Filter/FlateDecode/ID[4BEC58B7ACF35148A04DE5F4BB8A9676>]/Index[21 22]/Info 20 0 R/Length 98/Prev 443415/Root 22 0 R .
standard operating procedure for refractometer
Prior to any kind of measuring procedure a calibration should be effected. Zero point calibration may be carried out by using distilled water. This is the more convenient way to calibrate the refractometer, but not as accurate as the calibration with block, described under 7.2. Open the illumination prism [5], apply some drops of distilled waterThis reference manual provides full instructions and technical guidance the for safe and correct usage of the Excellence Refractometers R4 and R5. Our Excellence refractometers are easy-to-operate, high-performance instruments for measuring the refractive index of liquid samples. Learn how to calibrate a portable refractometer with an easy step-by-step guide in this video.
Adjust the calibration screw so that the refractometer reads exactly zero. Clean the daylight plate and the main prism assembly with a soft, damp cloth. Place 2 to 3 drops of the test solution and take a reading as before. Interpret the refractometer reading. This type of refractometer typically measures the concentration of the sugar in the .REICHERTTS METER Refractometer ... 8 1.0 INTRODUCTION The REICHERT TS METER Model 1310400A Total Solids Refractometer has been designed for simple, rapid microanalysis in biomedical, chemistry and classroom laborato-ries. The determination of concentrations of solutions is one of the oldest uses of refractometry. The TS METER RefractometerThe UR24 digital refractometer is a stand-alone unit designed for simple installation in-line or in a tank or vessel. It continuously measures concentration and displays and outputs the result in Brix or nD or % concentration with high accuracy.
Refractometer calibration materials are available with up to 5 decimal place RI and up to 2 decimal place Brix. Calibration Oils Calibration Oils are organic compounds that cover the range 1.47 -1.56 RI at the upper end of the Brix scale and beyond. Calibration Oils have a shelf life of 12-months. When calibrating the refractometer, you need to make sure that you use a reference solution that is suitable for your particular instrument. For instance, if you are using a honey refractometer with a reduced Brix scale, such as 90-60 Brix (or 10-30% water) which is common for honey refractometers, you may have problems calibrating it accurately if your .
