U.S. Patent No. 5,186,263

Discrete Soil Sampling... The LB Sampler remains completely sealed while being pushed or driven to depth for... Site Investigations. Brownfield Assessments, Remedial Investigations/Feasibility Studies, RCRA Facility Assessments/Investigations, Corrective Actions, UST Investigations and Removal, ASTM and USCS Soil Classification.

The Geoprobe® LB Soil Sampler is a closed piston sampler for soil sampling at discrete depths. Its patented design allows the sampler to remain completely sealed while driven to depth. Simply drive it to depth, open it, and retrieve a core. Easy driving, fast operation, minimal disturbance, no cuttings.

LB Sampling System Advantages:

• Patented design allows sampler to remain completely sealed while driven to depth.
• Recovers 22-inch long x 1.0625-inch diameter (559 mm x 27 mm) core, 320 mL in volume to depths of over 60 feet (18 mm).
• Samplers are pushed or driven to depth.
• Generates no cuttings during sampling.
• Liners available in CAB (clear plastic), brass, stainless steel, and PTFE (Teflon®).

The LB Soil Sampler collects discrete soil samples from depths of over 60 feet (18 m) depending on probing conditions. The sampler remains sealed (closed) by a piston tip as it is driven to depth. The LB Sampler recovers a 22-inch long x 1.0-inch diameter (559 mm x 25 mm) core. Maximum core volume is 283 ml.
