In Delivery In Purity In Price An independent survey was recently conducted without our prior knowledge by the school of business administration of a large, well known Eastern university. It revealed Aldrich's overall superiority. Among all those chemists who responded, the three criteria most often cited for supplier selection were availability of catalog listings, quality/purity, and price. Aldrich was listed Number One in all three of these categories. If you're not already an Aldrich customer, and you use organic chemicals, maybe you'd better take another look at the Aldrich Catalog/Handbook. If you don't have one, write for your free copy.
