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 ( L V ) L a b 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 ( L V ) L a b 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.

PURE DE-IONIZED WATER
"ON TAP" WITH LABORATORY-SIZE CARTRIDGE DE-IONIZER ILLCO-WAY Throw-Away Cartridge De-Ionizer consists of a clear plastic column con taining mixed-bed ionXchange resins. Produces an effluent pure enough for the finest analytical purposes, and can be used to reduce interfering ions often found in distilled water. Can be clamped in a special bracket (see above) or mounted on a regular stand (see left) and connected by tubing to nearest tap or other water supply. ILLCO-WAY Resins contain color indicator showing clearly when Cartridge is exhausted and needs replacement.
