Once you pick up the new Thomas catalog, g----— you won't want to put ^ ^ ^ ^ • - - i it down.

The plot of this book is very interesting but it's no mystery. It's clearly to make lab apparatus shopping easier for you.

This 1980edition lists 19,192 apparatus items—3,344 new since the last catalog printing—and 2,868 reagents. There's a total of 1,512 pages of valuable purchasing information about products from many manufacturers, including our own brands.

The Thomas catalog format is similar to an encyclopedia's. Items are listed alphabetically and assigned numbers. The lowest number is the first item listed and the highest is the last item. Number, product name and price are on a single line.

In addition, the catalog has clear, detailed product descriptions

with photographs or sketches and, occasionally, a diagram to give you a better understanding of the item.

When you need laboratory apparatus, our catalog will provide the information you require to shop more intelligently. For your free copy, write us on your company letterhead. Arthur H. Thomas Company, Vine Street at Third, Philadelphia, PA 19106.
