Effective integration of scientific instruments in the Grid

The paper presents a framework for Virtual Laboratory (VLab). Authors focus their attention on the application structure, which can make it possible to remotely use very expensive devices. It is important that this structure is universal and can be used with every device and every simulation. Therefore the framework is a critical issue in that concept. To prove the concept we plan to put into practice the Virtual Laboratory of Nuclear Magnetic Resonance Spectroscopy (NMR), which bases on this general structure. Another significant issue is to handle remote facilities like other Grid resources. This assumption generates new requirements concerning e.g. resource scheduling and global accounting.
