how to calibrate a veterinary refractometer schuco|urine refractometer : tv shopping Don't forget to calibrate your refractometer before you start. In this video Johan explains how to do that. With a practical tip to reset your refractometer . Always use a secondary container to place your autoclave load into. the container will help to capture anything in the event of a spill or boil over check to ensure the secondary container is .

Sterilab centrifuge tubes that are autoclave compatible should be autoclaved for 20 minutes at 121 °C. For more help on how to use an autoclave, read this helpful guide created by the University of Washington.
Pressing the flap down with your finger may also help to obtain a clearer image. There is an adjustable screw behind the stage. This moves the bimetallic strip and so allows the refractometer to be correctly calibrated with distilled water before it is used to test a urine (or plasma) sample. To calibrate the refractometer, first gather the necessary supplies (BOX 2, FIGURE 6). Then place a sample-equivalent volume of distilled water on the prism and close the cover before checking the reading.

Read the refractometer to determine the plasma protein. If the distinction between the blue and the white is blurry this can mean that there is insufficient plasma on the reading plate. Try pressing the lid down firmly as this can make the line clearer. Refractometers may have 2 .
Measurement of specific gravity involves calibrating the refractometer, taking the reading, and interpreting the reading. The refractometer prism should be cleaned after every use.Ensure the refractometer is correctly calibrated before use by ensuring that distilled water gives a reading of 1.000 on the S.G. scale. Pat the prism dry with paper towel to remove the water before adding the urine (otherwise your sample will be diluted and so give an artifically low result).Hold the refractometer up to natural light or an incandes-cent bulb to obtain the reading. Looking into the eyepiece, one should see a distinct separation between a blue and white sec-tion, often called a “contrast” line. If the contrast line is not directly at zero, then adjust by turning the screw on the top of the refractometer until it .This refractometer is specifically designed for the veterinary market with measuring scales based on animal chemistries. Scales include Urine Specific Gravity for Canine/Large Animals, Urine Specific Gravity for Feline, and Serum Protein for all Animals. View More
Direct reading – no charts or calculations. Easily cleaned between each measurement by flushing the plate with distilled water. Includes soft carry case and screwdriver. A single drop is efficient for rapid, accurate measurements of serum protein concentration, urine specific gravity and refractive index. See products. New. Schuco Clinical Refractometer. SHU2020. This model reads both serum protein concentration and urinary specific gravity. Will read refractive index of any solution. Gives direct reading, no charts or calculations.
