Guide to the Homogenization of Biological Samples

samples mechanical and physical methods that rely on grinding, shearing, beating and shocking are used. Mechanical homogenizers, manual homogenizers, mortar and pestles, sonicators, mixer mills, and vortexers are several of the more common tools used for mechanical and physical disruption. Sample disruption, or homogenization, is

Undisturbed sampling techniques

diameter samples is used. When the soil is sufficiently stiff or cemented to stand up under its own weight, a block sample may be taken. The normal technique is to cut a column of soil about 300mm cube, so that it will fit inside a box with a clearance of 10—20 mm on all sides. A box with a detachable lid and bottom is used for storage.
