Split Tube Sampler

SPT Split tube sampler is designed for carrying out the standard penetration test (SPT) to BS 1377: Part 9: 1990 and ASTM standards. The top ball valve adaptor, pair of split spoons, and open SPT Shoe compose a complete set of split tube sampler. A basket retainer made from steel or plastic also is available as an option with the sampler. The ball valve adaptor prevents samples from being washed out of the sampler when it is withdrawn from the borehole. A 60 degree nose cone or long solid rod with 60 degree point is available for carrying out SPT(c) tests in gravel and loose material. The screw connection on the top adaptor depends on the type of drill rods being used to drive the sampler. Most frequently used rods are 1-1/2” B.S. Whitworth, NWY, BW or AW

The standard split tube sampler is 2” (50.8mm) OD * 1-3/8” (34.9mm) ID * (457mm) / 24” (610mm) long. For heavy driving conditions, the heavy-duty “Tuflok” design is available
