Abstract: A bioprinter (1) comprising at least one printhead (4a, 4b, 4c) with nozzle (5), a printbed (20) onto which the printhead (4a, 4b, 4c) is arranged to print an ink, an ultrasonic sensor arrangement arranged at the printbed (20), a controller (7) arranged to control movement of the printhead/nozzle (4a, 4b, 4c; 5) and to perform calibration of the printhead/nozzle (4a, 4b, 5 4c; 5) based on information from the ultrasonic sensor arrangement.

Abstract: The present invention relates to a cell monitoring system for automatic cell monitoring and to a compact fluorescence microscope for high resolution live-cell imaging. The microscope comprises light sources (12), light source lenses (11), excitation filters (10), and beam combining means (9). The detector unit comprises emission filter (4), tube lens (5), and a detector (7) and optionally beam folding elements (6) for compactness. A dielectric mirror (3) combines and divides the excitation and the emission light.

Abstract: A dispensing system (1) comprising a material cartridge (2) provided with a nozzle (3), a temperature-regulating unit (4) provided with a nozzle temperature-regulating zone (5) arranged to regulate the temperature of the material cartridge nozzle (3) when the material cartridge nozzle (3) is arranged within the nozzle temperature-regulating zone (5), and a positioning unit (6) arranged for movement of the material cartridge (2) and the nozzle temperature-regulating zone (5) relative to each other between a first position (A) and a second position (B). In the first position (A) the material cartridge nozzle (3) is arranged within the nozzle temperature-regulating zone (5), and in the second position (B) at least a leading end portion (3a) of the material cartridge nozzle (3) is arranged outside the nozzle temperature-regulating zone (5).
