ECT Manufacturing supplies high-performance metal vibracore soil liners engineered for efficient vibrational energy transfer during sediment core sampling. Thin-walled aluminum core tubes feature a standard 3 to 4-inch outside diameter with a 1/8-inch wall thickness, delivering optimal penetration depths in silty sediments up to 20 feet. For heavy-duty offshore soil sampling and hard substrates, heavy-wall steel core barrels provide maximum structural strength for core retrievals up to 30 feet.
To prevent cross-contamination and protect field personnel when sampling hazardous sediments, metal core tubes can be fitted with disposable inner liners. Options include flexible lay-flat polyethylene tubing or rigid polycarbonate and CAB (cellulose acetate butyrate) plastic tubes. These clear plastic liners allow immediate visual inspection and sample processing while meeting U.S. Environmental Protection Agency guidelines for low-level contaminant analysis.
Ensure maximum sample retention during retrieval by pairing core barrels with stainless steel or flexible CAB leaf-type core catchers. Core catchers are securely attached with rivets at the lower end of the metal tube or cutter nose piece to prevent sediment loss. For fluid, oily, or highly cohesive clays, overlapping double catchers maintain sample integrity without inverting. Browse aluminum vibracore tubes, disposable inner liners, and retention accessories to optimize your environmental sediment sampling equipment.
