how to calculate refractometer factor|refractometer chart : sourcing What is a Refractometer? Refractometers are handheld, lightweight, portable instruments used to determine the concentration of water soluble fluids such as machine tool coolants, heat treating fluids, hydraulic fluids, plating baths, detergents, antifreeze, battery acid, etc.

The autoclave is a sealed device (similar to a pressure cooker) that kills microorganisms using saturated steam under pressure.
Digital refractometers are becoming more and more common to the industry. They rely on digital optics to obtain a °Brix reading. These can also be purchased from Lube-Tech. See more
Each coolant has its own refractometer factor which can be found on a product data sheet or determined using known sample concentrations. This refractometer . See moreRefractometer Calculator Converts refractometer readings taken of wort (Brix WRI) to their actual value in Brix / Plato and Specific Gravity. Supports alcohol correction of refractometer readings when calculating FG (which requires OG).
We have a complete guide with spreadsheet for finding your refractometer’s wort correction factor. A refractometer is a nifty brewing instrument that allows a gravity reading to . Each coolant has its own refractometer factor which can be found on a product data sheet or determined using known sample concentrations. This refractometer factor can be multiplied by the °Brix reading taken from the refractometer to .What is a Refractometer? Refractometers are handheld, lightweight, portable instruments used to determine the concentration of water soluble fluids such as machine tool coolants, heat treating fluids, hydraulic fluids, plating baths, detergents, antifreeze, battery acid, etc.How refractometers provide highly accurate results by considering all relevant factors is summarized in this video: Figure 9: Refractive index (λ = 589.3nm) of water at temperature T relative to vacuum, calculated according to Tilton & Taylor (1938)
Refractometers provide a quick, easy, and accurate way of testing and controlling coolant concentration. Watch Kurt Repsher demonstrate the correct way to use refractometers in our latest video.1. If the concentrate has a refractometer factor of 2, the refractometer will read 5%. Multiply the reading on the refractometer by the correction factor to get the true concentration (5 x 2 = 10%). 2. If the concentrate has a refractometer factor of 1.2, the refractometer will read 8.33%. Multiply the reading on the refractometer by the . Refacractometers are used to analyze solutions. Learn what a refractometer is, the different types of refractometers, and how to calibrate and use them.

Refractive index measurement checks the purity and concentration of liquid, semi-liquid and solid samples. Refractive index values can also be determined for gases. When using a digital refractometer, liquids and semi-liquid samples can be measured with high accuracy (e.g. down to .The reading on the measuring scale, recognizable by a clear color separation on the scale, indicates the concentration level of the emulsion. For some metalworking fluids, the reading on the measuring scale needs to be multiplied with the product-specific “refractometer factor”.
Place the water on the prism or lens of the refractometer. Close the cover and hold the refractometer up to a light source. Read the scale or digital display to get the refractive index. Convert the refractive index to salinity using a conversion chart or formula.
Using a Refractometer: Check the calibration of your refractometer. Water at 68° F should read 0.0 percent Brix. Open the cover plate and place a drop of plain water (no coolant) on the prism surface (see Figure 1). Close the cover plate to spread water over surface. Each coolant has its own refractometer factor which can be found on a product data sheet or determined using known sample concentrations. This refractometer factor can be multiplied by the °Brix reading taken from the refractometer to .What is a Refractometer?

If you just let them sit in the autoclave to cool off, tips will dry on their own. You can speed this process along by transferring your tip boxes to a heated drying cabinet (or even a spare incubator set at 55ºC).
