| Use: | Like augers, tubes can utilize a variety of tips depending on soil type. Tubes are considered better than augers for sampling VOCs. |
Description:
Tubes are similar to augers except that a tube with a cutting tip is attached to the drill rod. Instead of being rotated, the tube is pushed into the soil. Often, augers are used to drill the hole and tubes are used to collect the sample. A variety of tube samplers are available:
| Soil Probe: | Used for near surface sampling of cohesive, soft soils and silts. |
| Thin-Walled Tubes: | Used on wet or dry cohesive, soft soils. |
| Soil Recovery Probe: | Cores are collected in reusable liners to minimize contact with air. |
| Veihmayer Tubes: | Utilize pulley jacks and grips to sample at depths of 3 to 5 meters. |
| Peat Sampler: | Used for sampling of organic soils. |
