BÜHLMANN fCAL® turbo + CALEX® Cap (K191718): FDA 510(k) cleared. For in vitro Diagnostic Use.
Health Canada License: 98839

CALEX® Cap Extraction- for fecal Calprotectin & fecal Pancreatic Elastase

The BÜHLMANN CALEX® Cap has been introduced to fulfill the requirements of convenient and safe stool extraction.  The optimized dilution of stool sample yields maximum extraction efficiency while offering a stability of the calprotectin extracts for up to 3.5 days (84 hours) at 2-8°C, and for pancreatic elastase for up to 12 days at 2-8°C.  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 also shows very good correlation to gold standard weighing method for stool extraction and is therefore characterized by high reliability.


The design of the CALEX® Cap is fully compatible with automated procedures such as the FDA 510(k) cleared, BÜHLMANN fCAL® turbo, as well as the FDA Exempt BÜHLMANN fPELA® turbo, the random access immunoturbidimetric assays for measuring fecal calprotectin & pancreatic elastase, respectively.

Just like the BÜHLMANN fCAL® turbo,  this FDA 510k cleared, fecal calprotectin extraction device is unique in speed, quality, and flexibility.

Combine BÜHLMANN fCAL® turbo & BÜHLMANN fPELA® turbo with CALEX® Cap for Total Laboratory Automation (TLA)
  • Designed for TLA to streamline workflow
  • Enhanced ergonometry for automated and manual handling
  • Fast and easy stool extraction
  • High correlation to gold standard manual extraction
  • Optimal dilution offers excellent efficiency in extraction

Delivering Speed, Quality, Flexibility in Stool Pre-analytics

CALEX® Cap is designed to facilitate stool extraction by following 5 simple steps, therefore allowing for fast and reliable stool pre-analytics – the key to reliable results.

Time savings in stool pre-analytics are essential to manage increasing sample volumes.

The fecal calprotectin & pancreatic elastase testing workflow is further simplified when using the CALEX® Cap extraction device, reducing hands on time by ~70%

The CALEX® Cap extraction device combines ease of use and high comparability to the gold standard manual weighing method for the extraction of fecal calprotectin.

A Passing-Bablok regression analysis of 175 patient samples shows an excellent coefficient of correlation of r = 0.932 between the two extraction methods (Fig. 1).
