Abstract
A flow diverter, vacuum control and tilting of the liquid filtering system are used alternatively or in conjunction to reduce foam production in a filtered liquid sample. A liquid filtering system includes an upper sample reservoir, a filter and a lower storage bottle. A vacuum is applied below the sample filter to draw sample liquid through the sample filter into the storage bottle. A flow diverter may be used to direct flow of the filtered liquid sample onto a sidewall of the storage bottle or guide flow to a bottom of the storage bottle. The vacuum may be regulated to reduce foaming. The liquid filtering system may be tilted to direct fluid to the sidewall of the lower storage bottle and reduce foaming.
