The shell of the P-K Type (LV) Lab Blender can be charged from either side by the quick removal of either of two dust- and watertight covers.
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.
This new P-K Type (LV) Lab Blender owes its versatility to the design of the removable, spring-loaded liquid-feed bar assembly. Liquids and solids are prevented from entering the bearing housings by an exclusive, patented seal. Standard (LV) Lab Blenders are available in 8 and 16 quart capacities, in transparent Lucite or stainless steel. Interior of shell and stain less steel bar assembly can be cleaned, clin ically, in minutes. Operates on 115 ν AC. Units can be shipped from stock.
