Refractometer Vials - Abbe, circa 1935 Object Reg. No: HT 3501

Box of vials for use with Abbe refractometer, about 1935. Used by Commonwealth Serum Laboratories (CSL) Limited, Parkville, Victoria. Abbe refractometer measures refractive index (RI) and thus the concentration of liquids like serum. A drop is placed between prism and ground glass wedge. The RI is the number for the quadrant position when a black boundary lines up with a cross hair in the main eyepiece. Monobromonaphthalene is used to calibrate the Abbe refractometer.
