A modified beckman model du spectrophotometer for seagoing use


, : A modified beckman model du spectrophotometer for seagoing use. U S Fish And Wildlife Ser Spec Sci Rept Fish 382: 1-4

Several modifications of the Beckman DU Spectrophotometer are described which facilitate operation and maintenance on a seagoing vessel. These include the replacement of the desiccant holders in the instrument with readily accessible units of somewhat larger volume; the placement of the "C" battery supply in a separate compartment provided with a switch and meter jack, permitting rapid measurement of critical voltages; two trickle chargers for the 6-volt "A" batteries, provided with rate-of-charge meters; and a cell holder designed to accommodate as many as four 10 cm. semimicroabsorption cells.

In these simulations, we consider slip systems identifi...

Modifications led to a gain of MPEP site interaction through incorpor...
