The present status and problems of refrigeration and thermometry at microkelvin temperatures will be discussed. It will be shown that a better understanding of internal, time dependent heat leaks and of thermal boundary resistances as well as further progress in thermometry are necessary to reduce the present minimum temperature of about 10 ΜK to which matter has been refrigerated.
