Abstract:
The present invention relates to an apparatus and a system for filtering a liquid sample in a sample well (310) by transferring the liquid out of the sample well (310) through a filter member (320) situated at a bottom part of the sample well (310). The apparatus and the system comprise a syringe (100), and a seal member (200) arranged around a nozzle (140) of the syringe (100) in such a way that the syringe (100) is adjustable in connection with an upper part of the sample well (310) in a substantially airtight manner. The invention also concerns a method for filtering a liquid sample and use of the system for filtering eluted blood.
Abstract:
This invention relates generally to the processing of measured data. Especially the invention applies to the binning procedure of data which is measured with a CCD (Charge-Coupled Device) sensor unit. The invention is preferably used in photometrics for measuring radiation from samples on a well plate. It is the objective of the present invention to create a solution, in which a good signal-to-noise value is achieved, and the measuring results of the neighbouring sample wells can still be well separated. This objective is achieved in photometrics application by selecting the binning factor on the basis of position and size of sample wells on a well plate (530, 550). With the present invention it is possible to achieve a maximal signal-to-noise ratio, because all pixels within the image area of one sample are accumulated. However, since the pixels between the sample images are not accumulated with the pixels within the sample images (526, 546), the problem of interference between samples can be avoided.
Abstract:
A device for cutting off one or more sample regions from a sample carrier that contains impregnated sample material, e.g. blood, is described. The device includes: a cutting unit (103) for cutting off the one or more sample regions from the sample carrier, an optical imaging unit (101) for producing an electronic image of the sample carrier, and a processor (102) for controlling a display screen (108) to display the image (104) and one or more indicators (105, 105′) each expressing the location of one sample region to be cut off. Thus, an operator of the device is enabled to monitor, without direct visual communication to the sample carrier, what region or regions of the sample carrier is/are to be cut off. As no direct visual communication with the sample carrier is needed, the working ergonomics of the operator can be improved.
Abstract:
Sistema para filtrar muestras líquidas, comprendiendo el sistema: - una placa de muestra (300) que comprende una pluralidad de pocillos de muestra (310) para contener las muestras líquidas, teniendo cada uno de los pocillos de muestra un elemento de filtro (320) en su parte inferior, - una red de jeringas (100) que pueden conectarse a la pluralidad de los pocillos de muestra de modo que una jeringa se conecta con un pocillo de muestra, y - una unidad de control (500) para controlar el funcionamiento de las jeringas; caracterizado porque cada una de las jeringas comprende un elemento de sellado individual (200) dispuesto alrededor de una boquilla (140) de la jeringa de tal manera que la jeringa puede ajustarse en conexión con una parte superior de un pocillo de muestra de la placa de muestra de una manera sustancialmente hermética.
