A microscope slide staining system has a chamber, a plurality of slide support elements, a plurality of spreading devices positionable in association with microscope slides supported on the slide support elements so the spreading devices define a gap between the spreading device and the microscope slide and so the spreading device and the microscope slide are movable relative to one another to spread at least one reagent on the microscope slide independent of the other spreading devices and microscope slides.

A reactor system is disclosed. The reactor system includes a vessel configured to contain a solid support, the vessel including: a vessel wall defining a reaction chamber, the reaction chamber having a first end and a second end opposite the first end; a piston operatively arranged at the first end and configured to translate within the reaction chamber; a force measuring device coupled to the piston and configured to measure a load on the piston; a piston driver coupled to the piston; and a processor operably coupled to the force measuring device and the piston driver, the processor configured to: measure a load on the piston using the force measuring device, and adjust a position of the piston using the piston driver based on measuring the load on the piston.

Apparatuses and a method for plate-based oligonucleotide synthesis are disclosed. In one example, an apparatus used in oligonucleotide synthesis includes a synthesis adapter base to receive a commercially available synthesis plate. A keeper is used to apply pressure to the commercially available synthesis plate, and a sealing element is used to seal the commercially-available synthesis plate to the system adapter base. Other methods and apparatuses are disclosed.

The invention relates to an apparatus for analyzing heterogeneously catalyzed reactions comprising at least one reactor (3) through which a particulate catalyst flows and at least one reactant feed, wherein arranged downstream of each reactor (3) is a separation apparatus (17) for separating the particulate catalyst from a reaction product comprising condensable gases and arranged downstream of the separation apparatus (17) is a liquid separator (31) for separating liquid constituents from the reaction product, wherein the liquid separator (31) comprises a metallic tube (103) and a deflection body (119), wherein the metallic tube (103) is closed at its ends and the deflection body (119) is accommodated in the metallic tube (103) and the metallic tube (103) comprises a side feed (135) at a first end (105) and a gas outlet (113) at a second end (107) and the gas outlet (113) is connected to at least one sample vessel (37). The invention further relates to a process for analyzing heterogeneously catalyzed reactions in the apparatus.
