The PITCHER SAMPLER is designed to recover accurate samples from formations that are too hard for thin-wall shelby samplers or too brittle, soft or water-sensitive to permit satisfactory recovery by conventional core barrel type samplers. Several years of successful application in virtually every type of “problem” formation proves that PITCHER SAMPLER saves time and money, and ensures exceptional accuracy. Now uses standard 3x36” shelby tube as well as an NWJ connection. Call Acker at 800-752-2537 or visit to find out more.
