P-K's NEW (LV) LAB , BLENDER. YOU GET THESE 3 DIFFERENT MIXING ACTIONS... LIQUID-SOLIDS TYPE - To disperse and blend, uniformly, liquids of any viscosity with dry solids, just Insert the wire cage liquidfeed bar assembly. Handles liquids from mi nute quantities up to 40% of total weight. Liquid is introduced through hollow shaft of bar. Even critical formulations blended in 5 to 10 minutes.
INTENSIFIER TYPE — To get
intensive mix ing of hard-to-blend dry solids, or to break up agglomerates, use wire cage bar assembly. Average blending time for dry formulations· 3 to 5 minutes.
FOR GENTLE PRECISION BLENDING — Simply remove wire cage bar. Unique blend ing action will not cause attrition or break down even the most delicate crystals. Average blending time: 3 to 5 minutes.
