Britesorb BK 75 is a non-macerating silicic acid hydrogel. Optimal grain distribution and pore volume in addition to a large surface area create the requirements for good protein adsorption in beer stabilization.

Britesorb BK 75 is chemically inert, dust-free and is not attacked by either water or beer or silicic acid. Its use therefore does not breach German beer purity regulations and is permitted  according to the provisional Beer Tax Law §9, section.

Britesorb BK 75 has a very short reaction time: protein adsorption is completed within a few minutes. Britesorb BK 75 can be used both for flow contact stabilization and for tank stabilization. Longer contact times have no disadvantageous effect. Britesorb BK 75 facilitates long filter life.

Britesorb BK 75 acts physically and chemically and is specially tailored to the complicated colloid-chemical relationships in beer. It removes irreversibly only the protein groups which may cause low-temperature clouding. The protein groups responsible for head formation and head retention are not removed.
Britesorb BK 75 has no effect on the character of the beer. Taste and color of matured beers, extract content, alcohol content, degree of fermentation, pH value and bitterns are not modified by Britesorb BK 75.

Irreversibly removes proteins responsible for shelf life haze

Does not affect foam positive proteins

Can be used for stabilization in the tank or in beer flow pre-filter

Since the ratios are stored differently in every operation, the dosing must be adapted to the individual character of the beer and calculated through trials. The following figures may serve as guide values.
