HVE-61-000 High Voltage Electrophoresis system is for high speed analytical separations of low molecular weight ions including amino acids, peptides, amines, sugars, pharmaceuticals, steroids, inorganic ions, and proteins. The unit features a unique, highly efficient cooling system which uses tap water as the coolant eliminating the need for a refrigeration unit. The complete HVE-61-000 system includes the HVE cell, safety case, and a 5000-volt power supply. Camag Inc., 1 1 8 3 0 W. Ripley Ave., Milwaukee, Wis. 5 3 2 2 6 415

ANALYTICAL CHEMISTRY
Model 3 3 0 spectrophotometer provides both the accuracy required in research work and the simplicity and convenience desirable for teaching and routine use. Narrowing of the bandwidth to 10 nanometers and reducing the stray light to a maximum of 0 . 5 % have helped to provide the required accuracy. The precision grating monochromator coupled with electronic design and solid-state circuitry provide precise output for use with an external recorder or digital display device. Standard range of Model 3 3 0 is 3 3 5 - 7 1 0 n m . With an IR accessory, range is 6 8 0 - 1 0 0 0 nm; with an external deuterium lamp, 2 1 0 - 4 0 0 n m . G. K.
