WPA, Biochrom
®
Ltd
and UV/Visible Spectrophotometry
WPA Ltd was acquired by Biochrom
®
Ltd in 2002 because their range of colorimeters and innovative spectrophotometers provided
a perfect extension for the Ultrospec and Libra range of UV/Visible spectrophotometers. Together, these brands address the
market from hand-held colorimeters up to Pharmacopoeia compliant high-resolution products. The products are now designed
and manufactured at the Biochrom
®
factory on the famous Cambridge Science Park in the UK.
UV/Visible Spectrophotometry is a popular analytical technique used in most laboratories for a whole host of applications and
across the Biochrom
®
group there are products for every occasion. The guide below will assist with your WPA brand selection.
