内容説明
An important introduction to the use of the centrifuge in the biology laboratory, Biological Centrifugation is also useful for more experienced workers. The book describes the background and the principles behind centrifugation, including sedimentation theory. The book also considers the different types of centrifuge and other centrifuge hardware available, density gradient media and gradient technology. Although aimed primarily at the novice, this title also provides information to allow more experienced workers to modify and update existing techniques.
