Abstract: A method produces a filled and closed container by the blow-moulding, filling and closing method. An initially open container part (52) is held in a mould (46) and has been vacuum-moulded and/or blow-moulded by a blow pin and is filled successively with media (74, 76) of different types, in particular viscosity, by metering units (12, 14) via its free, upwardly directed container-part opening (54). The filled-in media (74, 76) are separated from one another in the container part (52), and subsequently, by closing of the top mould halves (56, 58) of the mould (46). A container top part (60) is moulded, and the container part (52) is closed, forming the container.

Abstract: The invention relates to a method for producing a filled and closed container, in particular by way of the blow-moulding, filling and closing method, in which an initially open container part (52) that is held in a mould (46) and has been vacuum-moulded and/or blow-moulded by means of a blow pin is filled successively with media (74, 76) of different types, in particular viscosity, by means of metering units (12, 14) via its free, upwardly directed container-part opening (54), such that the filled-in media (74, 76) are separated from one another in the container part (52), and subsequently, by closing of the top mould halves (56, 58) of the mould (46), a container top part (60) is moulded and the container part (52) is closed, forming the container.

Abstract: Photometer circuitry includes a capacitor discharge means for establishing a time period related to the light absorption properties of a test sample. The time period is used, in conjunction with a frequency generator to drive a digital counter to provide a digital indication of light absorption.
