    Notes: Abstract Many microbial fermentation processes exhibit different phases (e.g. adaption phase, main growth phase, main production phase). The process variables e.g. the biomass vary randomly about their mean. The experimentalist is interested to know the break points of the different phases, and a tolerance region, i.e. a range of possible values of the process variable that can be considered as normal. This paper deals with statistical methods for determining break points and tolerance regions.

    Notes: As a part of the Autoselect-system an eightfold diluter is described. Cassettes with 64 tubes are placed on the carriage of the machine and moved automatically in eight steps. One of the cassettes is loaded with separated samples in 64 tubes and the other one with 64 empty tubes. When the carriage stops, a defined volume of samples is exhausted by eight pipettes, mounted on a bridge spanning over the ground unit from left to right, and after beeing moved to the second cassette the pipettes deliver the samples into a row of empty tubes. At the same time by eight syringes mounted on both sides of the machine a defined volume of buffer is delivered through tubes and canules. By this way all samples can be diluted in two minutes.

    Notes: An automatic eightfold-pipetter has been developed with the same basic unit as the diluter of the Autoselect-system. The pipetter is fitted with eight pipettes on a bridge over the basic unit. By means of the pipettes a volume of 0.05 ml from eight tubes is exhauseted and delivered in the holes of a test plate. Both the test plate and a cassette with 64 tubes are located on a moving carriage. the test plate on the first floor and the cassette on the ground floor. If the pipettes transfer the samples from the tubes to the holes the distance between the pipettes must be changed by a special device from 20 to 30 mm, because the distance between the holes on the test plate differs from that of the tubes.For the transfer of 64 samples 2 minutes only are needed.
