Culture flask, accession no. 270; 1976
A special culture vessel was created to permit a shallow stationary layer of red cells remain undisturbed while providing them with a shallow layer of medium that flowed slowly and continuously over the settled cells. The culture was maintained at a constant temperature and under an atmosphere containing fixed percentages of carbon dioxide and oxygen.
