Scientists using liquid scintillation tech niques have long needed a reliable in strument that would reduce operating time and also the time spent processing raw data. The ANSITRON has been de signed with special emphasis on these objectives. Advanced logic design has reduced the number of controls thereby providing simplicity and speed of opera tion with no sacrifice in performance or flexibility. EXTERNAL STANDARDIZATION, de signed in as a basic part of the instru ment, permits accurate determination of quenching in single or dual-label ex periments. This eliminates the need for adding radioactivity to each sam ple thus reducing sample manipulation, eliminating pipetting errors, and leav ing the sample unaltered for possible future use. ELECTRONIC COMPUTATION reduces total data processing time to less than 12 microseconds per sample for a three channel instrument. Total print-out time never exceeds 5 seconds under any circumstances. LOGARITHMIC AMPLIFICATION com bined with pulse summation enables processing of beta pulses from 1 Kev to more than 10 Mev with no distortion, no overload, and no need for gain con trols or high voltage adjustment. β-Set plug-ins permit instant repetitive in strument settings. WHY A NEW LIQUID SCINTILLATION COUNTER? To supply you with the fea tures and reliability you need in an instrument: • • • • • • • • •
