SHELBY Tube Sampler
Product Code: Shelby_Tube_Samplers
Categories:
Thin-walled open tube samplers are designed for taking samples from soft and sticky soils.
These samplers have a much lower area ratio (approximately 10%) compared to U100 samplers and therefore provide less disturbed samples. However, some disturbance occurs due to the friction of the sample inside the sample tube.
The drive head is manufactured with a drill rod box connection according to customer requirements and has an air relief port and a simple arrangement for fixing the sample tubes with 3 set screws.
Sample tubes are available in cold drawn seamless carbon steel and stainless steel in various diameters and lengths. The cutting edge has a 30-degree chamfer feature.
