How to use haematoxylin in a sentence
The stain which brought out the cells with greatest clearness was copper haematoxylin.
By this means the colouring principle haematoxylin which logwood contains is changed into the true colouring matter haematen.
This reaction of haematoxylin is exceedingly rapid and delicate, rendering that body a laboratory test for alkalis.
By the action of hydrogen and sulphurous acid, haematein is easily reduced to haematoxylin.
