When you filter or separate...

...Kimble Funnels save you time Kimble " 5 8 " Chemical Funnels-Faster filtration because: Papers fit quickly and easily by simply folding in halves and then quarters. Only a narrow band at the top of the paper is sealed tightly to the bowl, leaving a large surface area of filter paper through which liquid can "bleed." There is a funnel for each of the sizes of commonly used filter paper.

Funnels can be used with suction in conjunction with filter cones without danger of paper tearing at high speeds. Inside stem diameter is as large as it

can be and still hold an unbroken column of liquid.

Kimble Squibb Separator/ Funnels-Faster separation because: They have 15% greater than nominal capacity which gives more shaking room for faster, more thorough mixing. Tight fitting stoppers and stopcocks prevent leaking during shaking. Larger neck openings make them easier to fill and clean. Taper of lower part of body has small inside diameter just above stopcock that permits accurate cut-off of liquid column . . . stem drains com­

pletely making quantitative separations easy and complete.

All Kimble funnels are fully annealed to effectively increase the mechanical strength.

Give your laboratory increased effi­ciency through faster filtration and sep­aration. Specify Kimble funnels when you order from your laboratory supply dealer. He'll be glad to give you latest information about prices, sizes and types. Or write Kimble Glass Company, subsidiary of Owens-Illinois, Toledo 1, Ohio.
