PERFORMS A WIDE VARIETY OF TITRATIONS—Neutralization, Oxidation-Reduction, Precipitation, Complex-Formation and other types. NO SPECIAL TRAINING IS REQUIRED-
Now—Simpler, Faster, Automatic Titrations!
automatic SIMPLE OPERATION: in a series of titrations, simply fill the burette, place the sample in the beaker—and the Beckman Automatic Titrator takes over from there. Raising the beaker holder into position automatically starts the stirrer motor and begins delivering titrating solution into the sample. A special circuit electrically anticipates the approaching end point, scaling down delivery of the titrating solution in progressively smaller increments to assure a highly accurate titration. When the end point is reached, delivery of the titrating solution stops and a light shows completion of the titration—all automatically and without attention from the operator. Whether your laboratory is large or small the Beckman Automatic Titrator provides important advantages in your titrating operations . . .
rapid and accurate titrations can readily be performed without special skill or technique. QUICK, SIMPLE OPERATION-completes many routine titrations in only 1-1 \\ minutes —even titrations to 0 . 1 % accuracy in 2 l/2 minutes or less. Change of sample is simple, rapid—a single motion raises, locates and secures new sample in operating position.
Here's another new Beckman advancement in instrumentation—an instrument that runs your titrations for you. It's the Beckman Automatic Titrator—the instrument that makes accurate titrations more rapidly and conveniently than by manual methods.
CONVENIENT, VERSATILE, ADAPTABLE0° to 100° C temperature compensation . . . adjustable holder accommodates 10 ml to 400 ml beakers or similar vessels . . . instrument may be used with all standard burettes down to 5 m l . . . as many as four delivery units accommodated by single amplifier control unit. . . . uses standard Beckman electrodes . . . electrode holders and delivery tip can be pivoted into any required position . . . ample provision for mounting heating devices or other special equipment.
such as preparing samples, or calculating results. • 7/ eliminates the fatigue caused by close observation required in manual procedures. • It gives objective, reproducible results... eliminates errors due to personal factors. • It provides time-saving conveniences for sample handling.
ALSO A RELIABLE pH METER-the Beckman Automatic Titrator can also be used as an AC-powered p H meter to give accurate readings over the range 0 to 14 pH, as well as millivolt readings from - 6 0 0 to + 1 4 0 0 mv.
