Refractometric reading
WebFor 128 pleural fluids, the relationship between the protein content and the reading for the specific gravity obtained from a refractometer calibrated for urinary specific gravity was analyzed. The refractometer gave falsely high levels for the specific gravity of the pleural fluid. A reading for 1.019 (rather than 1.016) corresponded to a concentration of protein … WebMay 31, 2024 · 179K views 5 years ago BRStv Product How To In today's BRStv How-To episode, Randy shows you how to properly calibrate and use your refractometer.

WebA method is proposed for urine specific gravity determination by urine refractometric index reading. Only two-three drops are required. Abbe refractometer is used. The urine specific gravity is determined by the formula: (formula: see text), where y = urine specific gravity, x = the refraction read. … WebOG reading on 7th April: 1.043 SG reading on 13th April: 1.025 SG reading on 14th April: 1.025 So its day 7 of fermentation and my reading appears to be stable, I assume fermentation has all but stopped, but the ABV is around 2.36% which is much lower than the 4.6% it should be at?
