Abstract

A pipette has a male cone on which a pointed nozzle can be pushed on with its female cone. This point includes a filter which rests with its lower face on three internal bosses. This filter can be made partly of inorganic material, topped by a layer of Kieselguhr or by a layer of polyester or acetate fibres. This filter is pref. coated with bacterial, fungicidal, or viricidal agents.
