20080280330 | COVER FOR SAMPLE WITH SAMPLE-SIZE INDEPENDENT HEIGHT ADJUSTMENT - The present invention relates to a device and a method for controlling the temperature of at least one sample. The device comprises at least the following means: (a) means for accommodating at least one sample; (b) means for heating and/or cooling at least one sample; (c) means for covering at least one sample. These means for covering at least one sample comprise at least one movable contact area and first and second means for fixating said at least one movable contact area in at least one defined direction relative to the sample. Therein said first means for fixating matingly engages with a corresponding second means for fixating. | 11-13-2008 |
20090155855 | COVER FOR SAMPLE WITH HOMOGENOUS PRESSURE APPLICATION - 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. | 06-18-2009 |
20100150203 | Tempering apparatus with testing device and method for testing a tempering apparatus - The invention relates to a tempering apparatus for the execution of a tempering program for at least one sample, in particular PCR-sample, comprising: at least one tempering block, which is configured for the reception of at least one sample, at least one tempering device, which is arranged for tempering said at least one tempering block, at least one temperature measurement device, which is assigned to said tempering device, at least one control loop for the regulation of a temperature, to which at least one tempering device and at least one temperature measurement device, which is assigned to said at least one tempering device, are assigned to, at least one control device, which is configured for the control of the tempering of the at least one tempering block, wherein the tempering apparatus comprises at least two temperature measurement devices, which are assigned to at least one control loop, and that to the tempering apparatus a testing device for performing a test method is assigned to, wherein said testing device comprises a signal-connection to at least one of said at least two temperature measurement devices, such that by means of said signal-connection at least one testing quantity of the tempering apparatus is detectable, which characterizes the operational status of the tempering apparatus. The invention further relates to a method for testing of a tempering apparatus, wherein the method comprises the following steps: starting of the method; operation of at least said first tempering device for the duration of at least one first period from at least one first time; detection of at least one measurement temperature from said at least one first temperature measurement device, which is assigned to said first tempering device, at least at a second time; determining at least one first testing quantity of the tempering apparatus by using said at least one measurement temperature; and comparison of said first testing quantity with one reference quantity. | 06-17-2010 |
