Stabilisers & Clarifiers

Hydrated Xerogels | Stabiquick Select

Stabiquick Select is a less dusting hydrated silica gel for the adsorption of haze forming protein compounds, with selected filtration properties. 
Stabiquick Select enables the brewer to meet all protein stabilization requirements and it achieves a higher filter through-put due to its selected particle size.
It allows less dusting handling conditions due to its moisture of approx. 39%.
