Steam sterilization, or autoclaving, stands as a key defense against microbial contamination. Utilizing steam under pressure, this method effectively sterilizes a wide array of medical tools and supplies.

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. USG can be measured in the clinic by using either an analog or digital refractometer. Some refractometer scales apply to only 1 species; others, to multiple species. Measurement of specific gravity involves calibrating the refractometer, taking the reading, and interpreting the reading. The refractometer prism should be cleaned after every use.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 .
z The steps of refractometer use are calibration, reading, and interpretation. z Refractometer calibration varies by type of refractometer but should be done daily. z Refractometers should be cleaned between each use. z Small volumes of urine can yield valuable information regarding an animal’s health status. Inadequate sample volumeEnsure 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).
3.0 Calibration Reichert Hand-Held Refractometers rarely need adjustment. To check adjust- ment, make sure the temperature of the instrument is between 70°F (21°C) and 85°F (29°C) and take a reading with distilled water. If reading departs from 1.000, correction can be made by adjusting the screw on the bottom of the instrument.Why Veterinary Specific Scales? Although refractometers are used to determine specific gravity, that measurement is not made directly. Instead, the instrument measures the refractive index of the solution that is correlated to specific gravity using a calibration curve built into the unit.
“competent” calibration laboratory can confirm the that calibration of the upper end of the scale. In the future, select an instrument that is easy to calibrate at both ends of the scale. Tag the instrument case with a tag that indicates the date of the last calibration and when the next one is due. Do not use an uncalibrated instrument.The refractometer is a small hand-held device essential for any practice laboratory. It measures the refractive index of solutions containing a variety of solutes. Uses. In the veterinary laboratory it is most useful for providing results for urine specific gravity and the total protein concentration of serum/plasma, body fluids and effusions.Don't forget to calibrate your refractometer before you start.
