The Geonor thin wall stationary piston samplers are designed for taking undisturbed cores in very soft to stiff clayes. Excellent undisturbed samples are also obtained in loose to medium dense sands if the bore hole is filled with drilling mud. With a sampling cylinder in steel (model K-200), various sample diameters are available: 54, 75 and 100mm with lengths between 500 and 800mm. With a composite sampling cylinder, protected by a steel cylinder (model K-100) the sample diameter is 54mm and its length 700mm.
