Automatic Sample Collector for Continuous Cultures

摘要

An automatic sample collector is described that samples growing cultures sequentially. It can be programmed to collect at preselected intervals (usually several hours apart) for a prescribed period (usually from minutes to hours). Samples are collected serially but during intermediate time periods; when the sample is not required, it is disposed of by diverting it into a discard reservoir. This device collects culture samples on a predetermined schedule and stores them under refrigeration for study at a later time.
