Description. Used for determining the particle size distribution of very fine materials such as silt and clay. The test set can be completed with the 22-T0058/A Constant temperature water bath. In order to obtain a better temperature control, the water bath can be fit with the 22-T0058/3 Cooling coil for mains water circulation.

Basic characteristics of soils Size range of grains. Aids to size identification; The range of particle sizes encountered in soil is very large: from boulderswith a controlling dimension of over 200mm down to clayparticles less than 0.002mm (2mm). Some clays contain particles less than 1 mmin size which behave as colloids, i.e. do not settle in water due solely to gravity.
