A biosensor comprises a unit, comprising a substrate and an enzyme, which when brought into contact with the substrate is adapted to affect the substrate so that its conductivity changes as a function of time and temperature, and an electric circuit. The unit is included as a component in said electric circuit and the electric circuit is activable by applying an electric field and/or a magnetic field over the same to generate a measurable signal which is dependent on the total resistance of the circuit. The invention also relates to the use of a biosensor, a label with such a biosensor and a method of indicating the status of a product with such a biosensor.

Biosensor and its use to indicate the status of a product

A connection device includes a first connecting device and a second connecting device, which are interconnectible for the purpose of transferring an aseptic fluid. The first connecting device includes an injection needle and a protecting sleeve which has an orifice that can be punctured and which at least partially surrounds the needle and is displaceable relative thereto. The second connecting device includes a rubber-like part, which is penetratable by the needle and resealable when the needle is withdrawn.

Aseptic connection device

A filling device (,) for filling a container (,) with a liquid has a filling duct (,) which is connected to a storage tank. On a carrying means (,) there are arranged a deformable tube (,) which forms a throttle portion (,) in the duct (,), and a squeezing means (,) which is arranged along the tube and which is adapted to act on the sides of the tube (,) and which, when operated to close the duct, is adapted to move countercurrently to generate a subatmospheric pressure in the duct (,) downstream of the squeezing means (,). The filling device also has a meter for measuring a discharged amount of liquid. In a method of filling the container, the duct (,) opens by the squeezing means (,) being moved from a squeezing position and the amount of liquid transferred to the container (,) being measured, whereupon the squeezing means (,) is returned to the squeezing position, the squeezing means being moved countercurrently to generate a subatmospheric pressure in the duct (,) downstream of the squeezing means (,).

Filling method and filling device

The present invention relates to a dosing device, or mixing device for mixing, in a continuous process, a flowing primary liquid with one or more added secondary liquids of a smaller quantity for obtaining a flowing liquid mixture at a permanent uniform mixing ratio of the mixed liquids.
