The apparatus consists of an iron plate, 33 X 33 X 0.6 cm, fitted with three upright iron rods, each 4 4 c m long (Fig. 1). Two aluminum rods clamped across the upright rods near the top ...

Novel apparatus for the automationof solvent extraction

greater than the monochromator's specification, it should be noted that the monochromator used in this study is over ten years old. Because this error is a rather smooth and stable function of wavelength, it is possible to calculate the wavelength of an unknown emission line in a complex sample to an accuracy better than the monochromator specification. The measured wavelength is slightly depen...

Continuous-Culture Apparatus for Long-Term Use1

The continuous production and harvest of uncontaminated cells for periods of several months are a major requirement inthe design of a suitable culture system. Many continuous-culture units have been reported previously (1, 2), and some units are now commercially available. However, in these units, rubber, metals, and other sources of potentially toxic extractives are not prevented from direct c...
