Geoprobe® Interlocking Split Spoon Sampler

Geoprobe® Interlocking Split Spoon Sampler

Tired of struggling to open your split spoon sampler, resorting to gripping with bench vises and beating with wrenches? Then you're ready to try the simplicity and speed of the patented interlocking split spoon sampler - a unique geotechnical innovation from Geoprobe® engineered to greatly benefit your field team. It is built to be stronger, last longer, and save both money and field time compared to a conventional split spoon sampler. Additionally, it meets ASTM Standard D1586 (see diagram).

The interlocking design provides axial alignment of the tube halves, making for a quicker assembly of the split spoon sampler. Each time it goes together it self aligns, creating a perfect fit. With the threads aligned, the cutting shoe and drive head can be threaded to the split spoon sampler. The threads are a multi-lead, which requires fewer turns during assembly and disassembly over conventional spoons. Less time is spent during assembly and disassembly, which speeds up each test interval.

In addition to time savings, the interlocking split sheath has two times the strength and durability of conventional spoons. Enhanced material properties and manufacturing result in greater longevity. Design plays an important role as well. Each interlocking point keeps the two tube halves engaged throughout the split spoon sampling process. The strength of these connections prevents the split spoon sampler from bulging in dense materials. It also keeps the tube halves tightly engaged even when over-filling of the sampler occurs.

We’ve been redefining the drilling industry for 30 years by producing solutions to meet or exceed our clients’ needs. That’s why our mission as a drilling rig and tooling manufacturer remains steadfast: Geoprobe Systems® pioneers and delivers innovative, cutting-edge products for technical drillers.

The shoes don't round off like traditional spoons and they don't get bent in rubble fill like traditional spoons. The very first two we had lasted a year-and-a-half of everyday use. The durability and workmanship is as good or better than anything else I've seen.
