stabifix smart solutions

This is where we use insights to power ideas and develop smarter tools that add new value for brewers. Here you will find STABIVAC®, a dust protection system for dust-free handling. The FILTERCHECK that helps predict beer filterability. And a smart solution based on a biochemical test is StabiProlin®, a method that can detect proteolytic enzyme activity in packaged beer.


Stabivac® is a device that provides dust-free handling of silica gels. It connects to kieselguhr dosing units used for the vacuum extraction of dust from filter aids. It uses waterjet assisted technology to contain dust. Stabivac® is made of stainless steel for safe sterilisation, it has no moving parts, and can be easily adapted for most dosing units for efficient and cost-effective dust control.


The Raible-Test, or the Raible Filtertest as it is often known, is now the most reliable method used to predict beer filterability. It gives brewers a definitive indication of how a beer will behave in filtration. The Filtercheck was developed as an easy-to-use, cost-effective filtration kit for the Raible Filtertest. Using only 200ml of beer the Filtercheck will predict a filter’s shelf-life and optimise kieselguhr usage. It will also detect variations in raw material quality, brewhouse processing, fermentation performance, and more.


StabiProlin® is a biochemical test that detects and quantifies proteolytic enzyme activity in packaged beers. It is often the case that a combination of high inactivation temperatures (including at pasteurisation) and dosing proteases after the boiling process the enzyme is present in the packaged beer. An enzyme without its substrate will remain inactive. That is why the basis of this assay is to supply any residual enzyme with its substrate. StabiProlin® is a proline-rich substrate that is catalysed by enzymes which act on proline containing proteins. This assay, as described in the technical paper ‘Assay for detecting technical proteolytic enzymes in beer’ by Kupetz et al. 2021, allows brewers to optimise the dosage of proteolytic enzymes.
