A method of bone cement preparation from a polymeric powder and a liquid component including a polymerisable monomer or comonomer by the action of a catalytic system. Particles of the powder are packed in a powder container having an inlet and an outlet port, while the liquid component is held in a liquid container. The liquid container is connected to te inlet port and a vacuum source is connected to the outlet port. A voided space between the powder particles is flooded by the liquid component that flows form the inlet port toward the outlet port under the influence of the vacuum source.
