Abstract: The present disclosure relates to a lid for a microtiter plate, which has a plurality of cavities arranged on a top of the microtiter plate and serve for receiving samples, wherein the lid is securable on the microtiter plate such that it covers of the microtiter plate. The lid has a basic body, which is embodied such that at least in regions, which are located above the cavities when the lid is on the microtiter plate, it is transmissive for light of predeterminable wavelength, and wherein the lid includes at least one closure element, which is embodied and/or arranged in such a manner that it closes at least one of the cavities in the microtiter plate when the lid is on the microtiter plate.

Abstract: Disclosed is a filtering method for isolating a substance from a sample. The method includes: providing a filter module having a sample inlet, a sample outlet, and a filter covering the sample outlet; introducing, via a sample inlet a first quantity of the sample into the filter module; conducting the sample from the sample inlet through the filter and the sample outlet by applying a pressure difference between a side of the filter facing the sample inlet and a side of the filter facing away from the sample inlet; measuring the pressure difference and/or a volumetric flow through the filter; comparing the measurement values to a predefined reference value; and ending the method if successively detected measurement values lie within a predefined range of values around the reference value. Disclosed also is a device with which the method can be carried out.

Abstract: The present invention relates to an apparatus (1) for controlling the temperature of a sample carrier (2), and to an automatable laboratory workplace comprising an apparatus (1) according to the invention. The apparatus comprises a heating device (2) having a heater (3) and a movable heating cover (6), which is arranged over the receiving region of the heater (3) and is designed to press the sample carrier (4) in a heating position (H) into the receiving region (3a) of the heater (3) with a predefinable contact pressure, and a transport device (8), which is designed to introduce the sample carrier (3) into the apparatus (1) from an insertion position (E) outside the apparatus (1).

Abstract: The present disclosure relates to an apparatus and to a method for production, especially continuous production, of nanoparticles, including a line to convey water with a predeterminable flow velocity and a system arranged orthogonally to the line for introducing at least one dissolved substance into the line for producing the nanoparticles.
