Add 0.244 g of Potassium dihydrogen phosphate to the solution. Add 1.419 g of Sodium phosphate dibasic to the solution. Adjust the pH to 7.4. Add distilled water until the volume is 1 .In short, you can dilute the tris powder to MQ-water and adjust the pH with HCl or NaOH, and add some NaCl if you want a more physiological salt concentration. Yes, you can put it to autoclave or filter it if you need sterile buffer.

Coolants must operate within a specific concentration window to maintain the right amount of lubricity and additive content. Refractometers are instruments used to obtain a °Brix reading, which measures the oil content present in a coolant mixture. Refacractometers are used to analyze solutions. Learn what a refractometer is, the different types of refractometers, and how to calibrate and use them. Portable optical refractometers are typically used to measure the presence of dispersed oil in a number of emulsions and solutions that require precise mixtures to work properly and to avoid corrosion and hazardous fumes.A refractometer is used to determine a concentration of a particular substance within a given solution. It operates based on the principle of refraction. When rays of light pass from one medium into another, they are bent either toward or away from a normal line between the two media.

what does the refractometer measure
Thus, F0=2.33 min. Hence, 30 minutes of sterilization at 110°C is lethally equivalent to 2.33 min. of sterilization at 121.1°C. (Compare this sentence with the definition of F0 value for easy understanding).
