The back of the holder is fitted with milky colour screen made of acrylic. Date. Procedure 1. It is black in colour. The device contains hemoglobin tube, pipette, stirrer, and a comparator. In Sahli’s method, hemoglobin in the blood sample is converted to acid hematin, which gives brown colour. The hemoglobin concentration is read directly from the calibration tube. Sahli’s manual hemoglobinometer operates based on the conversion of hemoglobin to acid hematin by the action of HCL. The acid hematin solution is diluted until its color matches exactly with that of the permanent standard of the comparator block. The hemoglobin concentration is read directly from the calibration tube.

The tube is then placed in the comparator, along with a tube Physical Object Item Type Metadata. Min. Since brown is more easily matched by the human eye than red (the colour of Hb), Sahli’s method for testing hemoglobin is one of the most acceptable visual methods. Acid Hematin Method Cyanmethemoglobin Method (CMG) a.k.a Drabkin’s Method The acid hematin solution is diluted until its color matches exactly with that of the permanent standard of the comparator block. In practice the hemoglobinometer proposed in 1902 by the Swiss scientist H. Sahli is used. A translucent white glass is Fitted at the back to provide uniform illumination for matching the color. If concentrated acid used in sahli's method for Hemoglobin test, it gives always the same color of any patients hb, so for different Hemoglobin concentration it can be used for Hemoglobin test. Sahli´s method. Simple rubber dropper: To add acid or water drop by drop. 1. Sahli's Haemoglobinometer. Product Details: Click to view more; Share Your Product: Ask A Question Send Inquiry. Place N/10 HCl into Hb tube upto 2 grams. With a medicine dropper, place 5 drops of the 0.lN HCl in the bottom of the graduated tube. Sahli’s hemoglobinometer . Comparator Block.
