The shell of the P-K Type (IV) Lab Blender can be charged from either side by the quick removal of either of two dust- and watertight covers.
NEW PRODUCTS down to 0.005 gram. Both dials can be turned without arresting t h e balance, so that quick readings are obtained. Accuracy of t h e balance is said to be 0.01 gram. T h e fine weighing dial has graduations of 0.02 gram from zero to one gram. T h e second dial for weight loading is graduated in one-gram increments from one to nine grams. Oscillations are oil damped for qtiick reading. T h e left side weighing p a n is removable to aid in transferring materials from t h e balance. T h e Torsion Balance Co.

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 minute 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 mixing 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 blending action will not cause attrition or break down even the most delicate crystals. Average blending time: 3 to 5 minutes.
This new P-K Type ( L V ) L a b Blender owes its versatility to the design of t h e removable, spring-loaded liquid-feed bar assembly. Liquids and solids are prevented from entering the bearing housings by an exclusive, patented seal.
