CD CO Have we told you about two newly available materials in the field of synthetic nitrogen chemistry? They're Pyrrole and N-Methyl Pyrrole. Both are highly reactive and have application in organic synthesis. We could set down here some physical characteristics, but instead we invite you to write for our latest technical bulletins. In them, we point out such salient facts as molecular weight, solubility, boiling point and many other interesting data designed to help you

determine whether you
may have applications. If you desire, we'll send sample quantities, too— no charge, of course. Should one of these chemicals seem to meet your needs, we'd be delighted to get together to discuss possibilities and problems.

..in Insecticides ., ,. , .. _____ ™™_Jthe problems of the insecticide chemist just begin when he finds a good insecticide. Then he must feed a tiny droplet to each b u g . . . or spread a thin layer on the bug or plant. The micron-sized drops from Sonic h o m o g e n i z e r s will get m o r e bugs "plastered" with more droplets from the same amount of insecticide than ever before. Sonic Homogenizers develop and use all the energy right in the liquids with only 1/6 to 1/10 the power, and at a fraction of the first cost, of conventional equipment . . . maintenance-negligible.
