Suction spectrophotometer cell.

A spectrophotometer cuvet is described which is emptied by suction without removal from the instrument. The use of this cuvet saves time and minimizes the chance of breakage. Data from C " measurements and absorbances of a dye solution show minimal retention error from successive specimens. expended in determining the absonbances of a large series of individual samples in a spectrophotometer can now be greatly reduced by the use of a rapidly emptying suction cuvet (Fig. 1). WiI.h the Beckman DTJ spectrophotometer, 50 samples were read by the Fit. 1. Spectrophotometer cell and sample collector; see text for explanation of parts. ID Sample tube usual procedure; use of the suction cuvet resulted in a 30% saving of time. The suction cell is designed to contain an internal small tube that reaches to the bottom of the cell and is placed so that it does not in-The suction cuvet was kimidly supplied by Echols
