Estimating the term…
The present invention relates to means for covering one or more sample(s) that are suitable to avoid or minimize evaporation and/or condensation of any vaporizable substance that may be present in the sample(s) or reaction mixture(s), in particular evaporation of substance at the fringes of a vessel or an array of vessels or condensation of said substance on the lid of a reaction vessel or a plate/block containing the sample(s) and/or the means for covering. This is achieved by providing a device comprising, among others, a force distribution unit that comprises at least one medium or material that is unable to withstand a static shear stress and deforms continuously under the action of a shear force. In a preferred embodiment, this medium or material is a gas, a shear force.
Device for controlling the temperature of at least one sample, wherein the device comprises at least the following components:
Device according to any one of the preceding claims, wherein an intermediate sheet or foil is provided between the sample(s) and the force distribution unit.
Device according to any one of the preceding claims, wherein at least one means for heating and/or cooling (4) is part of the means for accommodating (2) and/or is part of the means for covering (3) and/or is part of the force distribution unit.
Device according to any one of the preceding claims, wherein the means for heating and/or cooling (4) are selected from the group of resistance heater, fluid mediated heating/cooling, air/gas cooling, Peltier heating/cooling, Joule-type frictional heating and/or radiation heating.
Device according to any one of the previous claims, wherein the medium or material (10) of the force distribution unit has a thermal conductivity of at least 0.1 W·m−1·K−1 at 293 K, preferably at least 0.5 W·m−1·K−1.
Process for controlling the temperature of at least one sample, wherein said process comprises at least the following steps:
