MikroWin is a complete package for the flexible evaluation of all microplate test kits. The software can control a reading process for every microplate orientated reader. After the raw data is saved it is processed by a test specific parameter file. The results may be printed or exported. MikroWin uses a driver system in order to connect to the different istruments like mikroplate readers, automated liquid handling devices or host systems. Drivers for most of the photometric, fkuorometric, luminometric, LS/Gamma counter and multilabel microplate reader are already available. MikroWin provides the ability to evaluate any kind of screening assays using controls, classifications and calculation groups. It provides a large amount of curve fitting routines (linear or nonlinear), that can be used for the calculation of concetrations. It is also able to perform kinetic measurements and includes comprehensive data reduction algorithms.
