Abstract:
A cartridge for extracting and preserving a soil sample, the cartridge comprising:a cylindrical sampling barrel for insertion into soil for collecting a soil sample, the sampling barrel having a holder at the end of the sampling barrel, the holder having a bigger diameter than that of the sampling barrel, the sampling barrel having a rod-like ejector with a disk-like plunger to push the soil sample out from the sampling barrel; a first lid securable to a first threaded connection on the sampling barrel at a first side of the holder, the first lid having a concentrically located nipple component with a receptive hole in the middle of the top of the nipple component with a predetermined depth, the nipple component further having a locking slot for locking a detachable handle tool onto the first lid; and a second lid securable to a second threaded connection on the sampling barrel at a second side of the holder to seal the soil sample in the sampling barrel after it is collected by a septum positioned inside the second lid, wherein after the second lid is detached from the sampling barrel, the first lid is detached and reversed to put the ejector in the receptive hole of the first lid so that a force can be applied on to a rim of the first lid to push the ejector downwards, thereby retrieving the collected soil sample from the sampling barrel without the assistance of securing any handle to the cartridge.
