Using the Knowledge Base, customers can tap into Molecular Devices'
extensive knowledge of life science and drug discovery research in a single,
easy-to-navigate location. It is designed to benefit industry professionals
from a variety of sectors including laboratory managers, instrument users and
scientists performing research.

Researchers who conduct life science and drug discovery studies face
challenges staying up-to-date with developments in the industry. Information
in the Knowledge Base includes new application notes, technical guides,
manuals, software downloads, FAQs, installation guides, material safety data
sheets (MSDS) and articles from leading researchers within the fields of life
science, drug discovery, environmental toxicology and disease.

Mark Verheyden, President of Molecular Devices, commented: "By accessing
product information via the web, researchers are assured of obtaining the
most up-to-date information as quickly as possible."

Compared with the printed literature, the information available
electronically is much more extensive and will never become outdated. New
tools and technical advice in particular can reach the market more quickly
and we will no longer have to wait for the next publication before
researchers can obtain crucial new information.
