ALDRICH
Since 1951 we have been
contributing our expertise as chemists helping chemists around the world.
A significant part of our promise to our customers includes continuous
improvement in production capacities and capabilities, allowing us to
manufacture products to the exacting standard you require. Recent
enhancements include a major expansion of capacity for the production of
capacity for the production of air-sensitive chemicals in Sheboygan,
Wisconsin; a cGMP facility in the UK; and expansion of facilities at our
sister company, Fluka, in Switzerland. The acquisition of Carbolabs in
1997 makes phosgenation and other high-hazard chemistries available to
you. Almost 50 years of manufacturing experience enables us to find
creative solutions to your Fine Chemical needs, whether they involve
complex asymmetric syntheses, air-sensitive organometallic catalysts or
ultra high purity inorganic for materials science. [Top]

SUPELCO
With the development of four column packings for drug screening analyses,
almost 30 years ago, Supelco introduced the concept of Guanranteed
Performance (GP) gas chromatography columns and packings-products
designed, manufactured, and tested to provide chromatograohers with
assured performance for specific applications. Those four packings have
been followed by dozens of other Guaranteed Performance packings and
columns, many of which derive their exceptional performance from our
proprietary SUPELCOPORT, Carbopack, and Carboxen supports. GP packed
columns such as our Petrocol (for SIMDIS), Fluorcol (for Freons), and
Chromosil (for sulfur gases) columns remain popular choices for many
analysts. [Top]
