offers four outstanding advantages: This instrument

Easier, faster preoperation setup. Cuts accurate flow-adjustment time from 60 minutes to 60 seconds. Eliminates knob twiddling. And, the GC-45 has the most accessible column oven available. You don’t have to be a rubberarmed acrobat to change those delicate glass columns. In fact, you can turn the entire preoperation setup over to your technician, who can do the job in just moments.

High sensitivity for demanding applications. Despite its ease of setup and operation, the instru-

ment can handle the most critical

applications. Advanced temperature-control techniques enhance the GC-45’s available sensitivity and repeatability. New design and concept. The GC-45 all-solid-state circuitry increases sensitivity and reliability. Its newly developed components are the most dependable on today’s market. The new, one-piece, solid-cast detector compartment and heater also increases reliability. Service backup. This instrument, like all those manufactured by Beckman, is backed by an outstanding service organization and

by prompt, personalized application engineering consultation available from your local representative. Beckman’s leadership in scientific instrumentation has produced this highly reliable, totally new, laboratory gas chromatograph, and it all adds up to your spending more time on research.

If you’d rather spend time on research than setup, meet the new Beckman GC-45 gas chromatograph.

Briefly, this new gas chromatograph consists of a freestanding column oven with detector

and pneumatics, and a benchmounted, electronic control console. Various accessories are also available. Pneumatics. Time-consuming flow adjustments are reduced

through use of direct-reading pneumatic controllers. Carrier

gas flow is regulated with a reproducibility of 1%. Calibrated flowmeters are available for a variety of gases. Gas-flow toggle valves permit operation to be interrupted and later continued without need for recalibration or readjustment of flow. Column Oven. The column oven
