records the output from a spectrophotometer directly in percent Transmittance or Absorbance units! One operating feature stands out: Any 10% part of the full scale output from the Spectrophotometer can be expanded to the full 10" chart width! This fine critical resolution is only one feature of the Model 11. Designed to provide flexibility for the widest possible variety of recording applications, the unit provides a five chart speed range from .05 to 20 in/min. and a built-in event and speed marker.

For Simultaneous Concentration or Evaporation of Ten Samples in 10 to 20 minutes BUCHLER
ROTARY EVAPO-MIX Π For the evaporation of multiple samples of solutions, the Buchler Rotary Evapo-Mix is indispensable. It evapo rates directly from test tubes or centrifuge tubes and is suitable for evaporation of acids, bases and organic sol vents. The Rotary Evapo-Mix is equipped with a tempera ture-controlled water bath; it may be operated with an efficient water aspirator or mechanical pump. Π Another outstanding feature of the Rotary Evapo-Mix is the swirling action in the test tubes which increases the surface ex posed to vacuum thus increasing the speed of evapora tion. Π The Buchler Rotary Evapo-Mix is simple to operate, easy to maintain and inexpensive to purchase.

Beckman Instruments, Inc., of Ful lerton, Calif., has acquired the assets of Markham Laboratories, a small Chi cago laboratory that has specialized in producing high-quality diagnostic re agents for 22 years. Beckman has also announced the formation of "Automa tion Products Activity." Automation products will operate as a corporate en gineering advisory group to all the com pany divisions in the development of specialized data reduction systems built around both small digital computers and commercial time-sharing comput ers. They will also develop software programs for the computerized control of processes in specific industries. Three of these programs will relate to the fields of textile color control, spec troscopy, and liquid scintillation count ing.
