Abstract: A point of care testing (POCT) instrument for analyzing biological samples and a POCT system comprising a plurality of such POCT instruments is proposed. The POCT instrument comprises a housing, a measurement unit designed for collecting data indicative of at least one biological parameter of a biological sample, a main display, and an auxiliary display.

Abstract: A stacked substrate is produced using an apparatus including an injector head device. Production includes the steps of providing an injector head device comprising a gas bearing pressure arrangement and injecting bearing gas against opposite substrate surfaces, to balance the substrate without support in a conveying plane in the injector head device. The following steps are performed iteratively: contacting opposite substrate surfaces with a first precursor gas; and with a second precursor gas, first and second precursor gases supplied in first and second deposition spaces are arranged opposite and facing respective sides of the substrate; establishing relative motion between the deposition space and the substrate in the conveying plane; and providing at least one of a reactant gas, plasma, laser-generated radiation, and/or ultraviolet radiation, in any or both reactant spaces for reacting any of the first and second precursor gas after deposition on at least part of the substrate surface.
