Facts about LTP


  • The Laboratory for Thermophysical Properties (LTP) was founded in 1999 as an independent research organization and associate institute at the University of Oldenburg
  • LTP is a privately owned and managed company independed from any other company, institute or government department.
  • Our expertise in the field of experimental work for chemical engineering, chemical thermodynamics, and reaction engineering is based on longtime experience in consulting for chemical industry.
  • Since 2005 the LTP laboratories and office are located in the Marie-Curie-Str. 10 in Oldenburg together with the partner company DDBST GmbH.
  • Since 2018 the owners and managers of LTP are also involved in the management of the DDBST GmbH. This enhanced involvement of DDBST and LTP result in an improved service in the fields of thermophysical property data, consulting and supply, from literature data over experimental determinations to prediction methods.
  • LTP has more than 200 customers from industry and institutes worldwide
  • The customers are from more than 20 countries
  • Main customers are chemical and petrochemical companies, car and automotive manufacturer and supplier companies, aerospace and food industry, engineering companies and patent law firms.
  • More than the half of the global top 50 chemical producers are LTP customers.
  • About 100 small, medium, and large scale projects are completed every year.
  • LTP is very experienced in phase equilibrium measurements, e.g., vapor-liquid, liquid-liquid, or solid-liquid, also at high pressures over a broad temperature range. The laboratory works since many years on transport and caloric properties and PVT data at elevated pressures.
  • With more than 40 set-ups for thermodynamic measurements LTP covers a broad range in temperature (from about 180 to 870 K) and pressure (up to 1200 bar).
  • LTP can measure more than 20 thermophysical properties for gases, liquids, and solids.
  • LTP has about 15 employees including scientific researchers, laboratory, technical and administrative assistants.
