Oxygen Absorption Rates in Laboratory and Pilot Plant Equipment

Standardization of laboratory equipment.

Plant Culture Equipment.

A detailed description is presented in this paper of small sand and water culture equipment. A number of large out-of-doors sand cultures both for tree and annual crops have also been constructed at the U. S. Regional Salinity Laboratory, Riverside, California. In their general features these latter cultures are like those described in an earlier publication (3). The more significant modificati...

Diagnostic equipment outside the laboratory.

A questionnaire was circulated to clinical biochemistry laboratories in the North West Thames region of the United Kingdom requesting information on extralaboratory equipment. Data on the types and numbers of instruments in use, their relationship with the laboratory, and quality assurance procedures were obtained. Laboratories were prepared to maintain equipment over which they had no responsi...

Demonstration Plant Equipment Design and Scale-Up from Pilot Plant of a Leaching and Solvent Extraction Process

Germanium recovery from coal fly ash by hydrometallurgical procedures was studied at the pilot scale (5 kg of fly ash/h). Results were used to design the equipment of a demonstration-sized plant (200 kg of fly ash/h). The process is based on hydrometallurgical operations: firstly a germanium extraction from fly ash by leaching and a consequent Ge separation from the other elements present in th...

Whey Utilization III . Oxygen Absorption Rates and the Growth of Saccharornyces fragilis in Several Propagators AARON

could be scaled-up to apply to larger operations. Fifteen L of yeast-whey medium in a 40 L propagator were aerated at 30 L per min under conditions that assured an adequate supply of dissolved oxygen (Wasserman and Hampson, 1960). The oxygen consumption by the yeast was determined with the Beckman Oxygen Analyzer. To permit direct comparison with the values obtained in the smaller propagator, t...
