Abstract
A vacuum pipette has a filter grid that is shifted into its extended interior and whose cross section is considerably greater than the cross section of an end-side suction opening. The gaps formed in the filter grid can be so narrow that even very small components are reliably retained. Nevertheless, the entire passage cross section available is considerably greater than in the case of a filter grid arranged at the end side. As a result, favorable suction forces are generated under constant suction conditions.
