CALEX® Cap / CALEX® Valve Stool Extraction Devices

The BÜHLMANN CALEX® Cap has been introduced to fulfil the requirements of convenient and safe stool extraction. The optimized dilution of stool sample yields maximum extraction efficiency while offering a stability of the extracts for 3 days at room temperature. CALEX® Cap is the first and only stool extraction device suitable for safe air and land transportation according to IATA 650 (UN3373) regulations. The extraction using CALEX® Cap not only offers hygienic stool sampling, but is a highly precise stool extraction device characterized by an outstanding correlation to the gold standard manual extraction.

Furthermore, the design of the CALEX® Cap is fully compatible with automated procedures such as the newly introduced fCAL® turbo, the random access immunoturbidimetric calprotectin assay. Optimized dilution of stool extracts provides access to any of BÜHLMANN calprotectin assays such as Quantum Blue® and the calprotectin ELISA.

The CALEX® Valve Extraction device was introduced in combination with IBDoc® combining stool extraction and pipetting in one device, but can be used also with other BÜHLMANN calprotectin assays such as Quantum Blue®. It is based on the CALEX® Cap but features a valve that allows the release of a specified amount of stool extract directly onto a laminar flow test cassette. CALEX® Valve is intended for use in the BÜHLMANN calprotectin home testing application IBDoc® or in point-of-care settings using the Quantum Blue® Calprotectin Extended Lateral Flow Assay. Product launch of the CALEX® Valve kit is planned for early 2017.
