This kit is designed to complement the book Investigating Chromosomes by Dr. A. F. Dyer of the Department of Botany, University of Edinburgh, by providing the necessary basic chemicals and equipment for ten students (or ten pairs of students) to make their own preparations from living organisms.

Chromosome Fixative. Additional items required are as follows (not included):. 10 x petri dishes. Filter paper (to line petri dishes). Access to a waterbath at 60°C.
