The paper presents a model of a microfiltration filter for separation of biological microparticles from body fluids, including peripheral blood. The model used a single membrane filter with a homogeneous 2D transmission structure. In the model, the individual sieve with a uniform transmission structure in 2D space was applied. Because of the required survival of biological particles, the presented model was limited to the narrow filtration conditions that guarantee biological activity of these particles. In this model, the filtration process proceeds in the gravitational field without the involvement of external forces forcing or inhibiting the filtration process. Based on this model there were given basic dependencies describing the required filtration process conditions, such as filtration time and internal forces for particle migration in the filtered body fluid. The basic relationships between the height of the filtered column, duration of the process, and average fluid expenditure of the filtration process for different shapes of the channels molecular drainage lines filter have been determined. Based on this data, the directions of further works on improving the presented model of molecular filtration of biological particles for enriching selected biological fractions have been described.Keywords: micro filtration, filter sieves, filter membranes, filtration of biological particles, filtration membrane
