sets, digital readouts, built-in diagnostics, and a vacuum-encased induction drive system. Beckman 412 Moisture detection. KFS-186 Karl Fischer aquametry system can be used with any pH meter for detecting moisture in food; grain; paint; paper and petroleum products; drugs; and chemicals. The system uses a solid-state circuit that generates its own polarizing current and displays the end point directly on a pH meter. Lazar 408 HPLC detector. Spectromonitor 3100 variable wavelength LC detector features linear operation from 2.0 to 0.001 AUFS. Absorbance can be measured throughout the UV-vis range (190-700 nm). A 10-mm path length high-efficiency and pressure maxN series fluid cell is included. LDC/Milton Roy 409
