1) Dissovle 250 g of polyethylene glycol in 300 ml of ddH2O by stirring. 2) Add ddH2O until final volume is 500 mL. 3) Autoclave to sterilize. 4) Store at 4°C.

Refractometer Calibration Made Easy with RODI Water
Refractometers need calibration from time to time and in this video I am going to walk you through adjusting the calibration on your refractometer.
I was using R/O water to calibrate my refractometer. I wasn't having any issues with the tank but I thought it would be a good idea to buy some calibration fluid from BRS just to make sure it was fine. I thought my salinity was at 1.026, when in reality it was close to 1.022.
The BRS refractometer comes with calibration fluid and a big orange card telling you to ignore the instructions and use the fluid to calibrate. Also make sure you have a quality refractometer that is temperature correcting, and give it 1 .
The standard for a refractometer is pure water and RO/DI qualifies. However, just to let you know, I just ran tap water on two refractometers here in the laboratory and both read 1.000. Even though the tap water is over 300 ppm TDS.
yes you can use rodi to calibrate the meter as long as you are sure that you have zero tds. It is good lab practice to always use a standard when calibrating any type of equipment. The standard for a refractometer is pure water and RO/DI qualifies. Follow these simple steps to calibrate your refractometer: Step 1: Prepare a calibration liquid – Start by obtaining a calibration liquid with a known refractive index. Typically, distilled water is used for this purpose.
For most functioning, non-damaged refractometers, RO/DI water is a sufficient calibration fluid. Now if you dropped it or suspect something isn't right, then invest in a calibration fluid. Or make your own (35 grams NaCl into 1 liter DI water = 35 ppt saltwater ~ 1.026)
Lesson learned about using R/O for refractometer calibration
If there is a discrepancy with the reading and the value you know to be true, then you will need to calibrate your refractometer. The reading error (or tolerance) taken at a set point (most commonly zero) can be corrected by dialling in the instrument using the capabilities of .Point the refractometer toward a natural light source since artificial lighting can cause the reading to be inaccurate. Look into the eyepiece and adjust it so that the scale is in focus. Adjust the calibration screw so that the refractometer reads exactly zero.Proper calibration requires a pure water source and testing solutions of known sucrose concentration. Water allows the user to “zero” the refracto-meter so fruit juices can be correctly measured. An ideal water source is deionized (DI) or distilled water - water that has been filtered to remove ions such as sodium, calcium, iron Refractometers need calibration from time to time and in this video I am going to walk you through adjusting the calibration on your refractometer.
