Ν0W-S//n/?ter, Faster, Automatic Titrations! Here's another new Beckman ad vancement in instrumentation —an in strument that runs your titrations for you. It's the Beckman Automatic Titra tor—the instrument that makes accu rate titrations more rapidly and con veniently than by manual methods.
SIMPLE OPERATION: in a series of titrations, simply fill the burette, place the sample in the beaker—and the Beckman A u t o m a t i c Titrator takes over from there. Raising t h e beaker holder into posi tion automatically starts the stirrer m o t o r and begins delivering titrating solution into the sample. A special circuit electrically anticipates t h e a p p r o a c h i n g end point, scaling d o w n delivery of the titrating solution in progres sively smaller increments to assure a highly accurate titration. W h e n the end p o i n t is reached, delivery of the titrating solution stops and a light shows com p l e t i o n of t h e t i t r a t i o n — / » / / automatically and without at tention from the operator.

NO SPECIAL TRAINING IS REQUIRED rapid and accurate titrations can read ily be performed without special skill or technique. QUICK, SIMPLE OPERATION-completes many routine titrations in only 1-1 ^ minutes —even titrations to 0 . 1 % accu racy in 2 '/2 minutes or less. Change of sample is simple, rapid—a single motion raises, locates and secures new sample in operating position. CONVENIENT, VERSATILE, ADAPTAUf0 6 to 100° C temperature compensa tion . . . adjustable holder accommo dates 10 ml to 400 ml beakers or simi lar vessels . . . instrument may be used with all standard burettes down to 5 m l . . . as many as four delivery units accommodated by single amplifier conrrol 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.
