Abstract: The present invention refers to a device and method for stereolithograpic three dimensional (3D) printing comprising: a) a container adequate for containing a photopolymerizable polymer, b) at least one laser generator emitting a light beam with a wavelength between 360 nm and 1000 nm, c) modulation means for modulating said light beam into at least two light sheets which are matrices of light, and d) means for irradiating said light sheets in the container containing said photopolymerizable polymer; wherein said at least one laser generator is arranged so that said at least two light sheets are crossed inside said container, leading to polymerization of the photopolymerizable polymer at the crossing of said light sheets.

Abstract: A cover lid collector (10) for a sample carrier (40) for cell cultivation, wherein the cover lid collector (10) comprises a connecting portion (12) for engaging with the sample carrier (40) for closing the same, wherein the connecting portion (12) defines a first plane (11). The cover lid collector (10) further comprises a cavity (14), which when the cover lid collector is engaged with the sample carrier (40), has a cross-section that decreases in a direction perpendicular to the first plane (11) and pointing away from said sample carrier (40) between a near end (16) of the cavity (14) and a far end (18) of the cavity (14), wherein the near end (16) is closer to the sample carrier (40) than the far end (18).

Abstract: A capillary cell is described along with an arrangement and a method for receiving, positioning and examining a microscopic specimen, in particular a cleared fluorescent specimen with the help of a single-plane fluorescence microscope. The capillary cell is suitable for being positioned in a chamber volume and contains a capillary section, which comprises a wall. The wall encloses a specimen volume and is planar and transparent in at least some sections. In addition, the capillary cell includes an upper and a lower closure section, which are connected to the capillary section and which seal the capillary section. The specimen volume is separated from the chamber volume by the capillary section, the upper closure section and the lower closure section.
