I have a haemocytometer made by e.cogit & cie paris, itīs made entirely of brass, an arrangement with ring is lowered onto the glass disc which contains the grating, much like a compresorium. The case is in poor condition but there are two pipettes signed e. cogit etc. Anyone any idea of age price? Many thanks, Aline.
