Abstract: The present invention is directed towards a microfluidic device comprising a first compartment comprising an inlet that is connectable to a fluidic control unit and a second compartment, wherein the first and second compartments are connected by a micrometer channel so as to allow fluid communication between the two compartments. The device also comprises an air-lock element in fluid communication with the second compartment and the air-lock element is configured so that in use the internal atmosphere of the device is sealed from the external atmosphere and so that when fluid is introduced or withdrawn from the first compartment via the inlet the air-lock element maintains an overall constant pressure within the device. The present invention is also directed towards a method of manufacturing the microfluidic device, a kit-of-parts comprising the microfluidic device and a method of using the microfluidic device for accommodating, growing, culturing, isolating, treating and/or processing cells.

Abstract: The technology describes a stamp and stamp pad for a self-inking stamp, having a housing or a carrying device for a pad for absorbing ink. The carrying device is rectangular in shape, having a base plate with longitudinal surfaces and lateral surfaces moulded thereon. On two surfaces running in parallel handle elements for the lateral gripping of the carrying device are arranged. On the lateral surface a handle element for the lateral gripping and pulling of the carrying device out of a stamp are formed of a plurality of parts displaceable within one another. The handle elements are formed for insertion in a clearance of a lower part of the stamp and do not protrude out of the outer surface of the lower part, so that an upper part of the stamp is displaceable via the clearance with the handle elements inserted in the lower part.

Abstract: The invention describes a stamp (1) and stamp pad (130) for a self-inking stamp (1), wherein in a housing (131) or a carrying device (11) at least one pad for absorbing ink is arranged. The carrying device (11) is formed rectangular in shape from a base plate (135) with longitudinal surfaces (136) and lateral surfaces (136) moulded thereon, wherein on two surfaces running in parallel handle elements (138) for the lateral gripping of the carrying device (11) are arranged. Preferably means in form of grooves (133), catches and/or elevations (134) for the fixing in a stamp (1) are arranged on the carrying device.
