Geoprobe - Model LB - Large Bore Soil Sampling Systems
The LB Sampler is a solid barrel, piston-sealed, direct push device for collecting discrete interval samples of unconsolidated materials at depth. The sampler is approximately 30 in. (762 mm) long and has a 1.5 in. (38 mm) OD. The LB Sampler is capable of recovering a discrete sample core 22 in. long x 1.0 in. diameter (559 mm x 25 mm) contained inside a removable liner. Sample volume measures up to 283 mL. The liner is a removable / replaceable thin-walled tube that fits inside the LB sample tube. Liners facilitate retrieval of the sample and may be used for storage when applicable. All this without generating any drill cuttings! In today's marketplace it is primarily used for manual sampling applications.
