A covering for apertures of reaction receptacles formed in a microtitration plate, including a hermetic, elastically deforming mat or foil, a frame, and connecting elements. The mat or foil, upon planar deposition on the microtitration plate and following compression, seals the apertures. The connecting elements are fitted onto at least one of the mat or foil and frame and detachably secure the mat or foil to the frame while creating a tension in the mat or foil implementing the connection. The frame () is dimensioned so as to permit the frame to be deposited on the microtitration plate (), such that the mat () or foil rests in a planar manner on the microtitration plate, and such that the frame is accessible from above to a pressure and/or heat applying device.

Covering for the apertures of reaction receptacles constituted in microtitration plates

A liquid proportioning method using a chamber for a gas and a reception volume connectable thereto for a liquid with an aperture to the environment, wherein a desired volume is predetermined for the liquid to be taken up by the reception volume, a chamber negative pressure is determined which has to exist in the chamber to cause the desired liquid volume to be taken up in the reception volume after the aperture is dipped into the liquid and the chamber is connected to the reception volume, the chamber negative pressure is produced in the chamber, the reception volume dips its aperture into the liquid, and the chamber is connected to the reception volume and the desired volume of the liquid is taken up in the reception volume.
