how to calibrate a urine refractometer|refractometer labelled diagram : maker To calibrate the. Place a small volume (one or refractometer, firstly ensure that it is clean. Wipe the surface with a clean tissue and distilled water. two drops) of distilled water onto the reading surface and close the lid. Look through the eye piece and ensure that the line. Technically, you can autoclave everything on this list, but the plastic will either melt or weaken. Only autoclave these types of plastic when you need to dispose of them, and make sure you .

Bottles, closures, plugs and gaskets can be autoclaved. Wash and dry thoroughly all bottles, closures, plugs and gaskets prior to autoclaving. The recommended parameter for autoclaving .
Calibrate the refractometer by placing distilled water on the glass as the sample, and adjusting the scale to read 1.000. This should be done before you begin testing, and after every ten samples .
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.Calibrate the refractometer by placing distilled water on the glass as the sample, and adjusting the scale to read 1.000. This should be done before you begin testing, and after every ten samples or so to ensure that the calibration remains accurate.

Wipe the surface with a clean tissue and distilled water. two drops) of distilled water onto the reading surface and close the lid. Look through the eye piece and ensure that the line.In this video, an Instrument Choice scientist demonstrates use an optical refractometer for urine (specific gravity).This video shows Dr. Evan Matthews explaining how to assess specific gravity of urine using a refractometer.In this video, an Instrument Choice scientist demonstrates how to use a digital refractometer for urine (specific gravity). In this video we use the Digital Hand-Held Pocket Urine.
Measurement of specific gravity involves calibrating the refractometer, taking the reading, and interpreting the reading. The refractometer prism should be cleaned after every use. Calibrate the refractometer with a standard solution before use. Since the reading will be affected by temperature changes, it's best to calibrate at the temperature of the test environment. If this is not possible, correction charts may be used.This includes thoroughly cleaning the prism and well after each sample and routinely calibrating the instrument. Always store the instrument with the well clean and dry. 2.0 SPECIFICATIONS.

Several types of refractometers are suitable for measuring specific gravity. For this demonstration, we have chosen the IC300005 clinical refractometer to showcase the technique required using an optical refractometer to measure urine's specific gravity (and refractive index). 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.
