20090280572 | Analysis device - A device is disclosed, being an analysis device for the study of biological or chemical samples by means of a reagent liquid supplied via a pipette. The device has an instrument housing with a base plate, a working plate arranged on the base plate horizontally to receive the samples in a sample holder having several wells, a robot manipulator arranged above the working plate, which carries a horizontal support arm with a slide. A needle system is fastened to the slide and can move in the Z direction, carrying 3 needles and being brought into vertical positions by a first vertical drive. The needle tips can be placed in an upper position above and in a lower position below a well. The middle needle can move vertically relative to the other two needles, which can be raised and lowered by a second vertical drive. The horizontal spacing of the three needles is so small that all three needles can be positioned with their tips inside the same wells. In particular, the working plate is mounted on the base plate so that it can turn. | 11-12-2009 |
20140300727 | METHOD AND DEVICE FOR INSPECTING THE VOLUME AND THE COMPOSITION OF AT LEAST ONE SAMPLE - The present invention relates to a method and a device for inspecting a volume and/or a composition of at least one, especially fluid sample. The method comprises the steps of making available at least one pipette, in which an interface is formed between the sample and a fluid which is adjacent to the sample, said interface being optically perceptible outside the pipette as an interface line between the sample and at least one fluid that extends essentially horizontally; of arranging at least one marking of a camera in an image field of the camera such that the marking and at least a first section of the at least one pipette are shown in a recorded image, the at least one pipette being arranged between a light source and the camera such that at least one spectrum of light beams of the light source is recorded by the camera, which light beams have penetrated the sample; of evaluating whether the marking in the recorded image matches the position of the at least one interface line in the at least first section; of comparing the at least one recorded spectrum with at least one reference spectrum; and of determining whether the composition of the at least one sample according to the at least one recorded spectrum corresponds to that of the at least one reference spectrum. | 10-09-2014 |
20140315226 | Device And Method For Detecting Substances Present In Biological Or Chemical Samples - The present invention relates to a device and a method for detecting substances which are present in biological or chemical samples, each substance producing an optically detectable signal upon reaction with a reagent. The device further comprises a sample carrier with at least two receptacles for receiving samples and is characterized in that at least part of the receptacle is equipped to receive at least 2 reagents each, and in that a camera for recording an image which shows at least one receptacle filled with at least two reagents for the detection of different substances, and an evaluation device for evaluating the samples which device is designed such as to evaluate each image by analyzing the signals in the image. Said method comprises the following steps: Introducing at least two reagents into one receptacle of a sample carrier, and optionally immobilizing the reagents, adding the sample to the receptacle, recording an image by means of a camera such that the image shows the receptacle which is loaded with at least two reagents, and evaluating the image by analyzing the color spectrum of the samples in the image. | 10-23-2014 |
20140320632 | Device And Method For Inspecting A Volume Of A Sample - The present invention relates to a device for inspecting a volume of a sample, said device comprising a pipette in which an interface is formed between the sample and a first fluid which is adjacent to the sample, said interface being optically perceptible outside the pipette as an interface line between the sample and the first fluid that extends essentially horizontally. The device further comprises a camera having a marking which is arranged in an image field of the camera such that the interface line and the marking can be imaged in a recorded image. The device finally comprises an evaluation unit which allows an evaluation of whether in the recorded image the marking is at the same height as the interface line. | 10-30-2014 |
20140320642 | Device And Method For Detecting Substances Present In Biological Or Chemical Samples - The present invention relates to a device and a method for detecting substances which are present in biological or chemical samples, each substance producing an optically detectable signal upon reaction with a reagent. The device further comprises a sample support with at least two containers for receiving samples and is characterized by a camera for recording an image which shows at least two containers, and an evaluation device for evaluating the samples which device is designed such as to evaluate each image by analyzing the signals in the image. Said method comprises containers, recording an image by means of a camera such that the image shows the at least two containers, and evaluating the image by analyzing the signals in the image. | 10-30-2014 |
