Build large t r a n s p a r e n t models like these polypeptide chains — and handle them with ease. The space filling Courtauld Atomic Models are the only system with elastically distortable bond angles. They are novo made of hollow plastic — strong and light. Brass connecting links are housed in a new plas tic turret — assembly is fast, easy and without tools. Molecules have open structures — bond lengths and directions can be studied and measured.

I GOOFED! (I didn't buy α Taylor Comparator the first time.) I thought comparators were pretty much the same, but, was I wrong! Broke two of those fragile, individual glass standards the first week . . . and things were really fouled up. Got a Taylor Comparator as soon as I could . . . and I'm reaHy sold on Taylor. You can't beat a slide with all the color standards right in it for convenience and easy use. Taylor Comparators — with guaran teed non-fading color standards in a single slide — let you make fast, easy, accurate tests for pH chlorine, phosphate, silica, nitrate and chro mâtes, etc. . . . right on the spot. You get dependable data to help you control chemical processing, water purification, waste treatment.
ALSO AVAILABLE Taylor Midget Iron Tester, Taylor Water Analyzer for colorimetric water analysis.
