Terms and Conditions of Use


DDBST GmbH provides this online search service free of charge. The price of the full data sets are calculated as follows:

Each data set is priced according to the number of data lines (a line is typically a measured data point, see also the information page "Sets and Points in the Dortmund Data Bank"). The prices without value-added tax (VAT) are:

No. of linesPrice in €
1    12
2 - 5 25
6 - 19 50
20 - 39 80
40 + 120

Data sets from a single source and with a single property are normally combined. E. g. five isobaric VLE data sets for Ethanol/Water with each 10 data points at five different pressures from a single source can be sold as a single 50 points set. This would cost 120 € instead of 250 €. Special lower conditions can apply for bigger single orders when more data sets are bought together.

Important Note: The prices shown here are only valid for small amounts of data sets bought through this online service. Prices for data sets in partial or full data banks are much lower (as low as 1 €). Please contact DDBST for more information about prices and licenses.
