Haemoglobinometer
About this object
Also known as a Sahli, after its inventor, this piece of equipment was used to test haemoglobin, or Hb, which carries oxygen around the body. A small amount of blood (from a pin-prick on the finger) was drawn up in the curved pipette, then moved by dropper into a tube holding 10ml of dilute hydrochloric acid. While water was added slowly it was carefully stirred with the glass rod, until a standard colour (in the window on the left) appeared. The level of Hb was found by measuring the amount of water used: high Hb needed more water to meet the standard, but low Hb (indicating anaemia) needed less
