The QS Fibre Beater can play an important role in pulp sample preparation. It has a thirty-second slurry function which effectively disintegrates and slurries slush pulp samples. It also has a five-minute mode to disintegrate AND condition dry lap pulp samples. Conditioning action rehydrates cellulose fibres, causing them to swell and lose some curl and reduce kinks. This results in more precise zero-span pulp strength measurement and AutoImager fibre size classification.
