Used BECTON DICKINSON FACSCalibur #293629334 for sale

BECTON DICKINSON FACSCalibur is a laboratory instrument and accessories used in laboratories for the analysis of biological samples. It is an automatable flow cytometer that extracts, counts and sorts cells based on their fluorescent and scatter properties. The instrument can detect minute physiological characteristics of cells and employ them to identify and quantify target populations. FACSCalibur operates on the principle of flow cytometry. This method uses a laser attached to a sample chamber and a computer-controlled shutter system to measure and count the size, shape and fluorescence of individual cells. The software, then rapidly sorts and analyzes different characteristics or properties of cells or other particles. The instrument is comprised of two main parts; the sample chamber and the fluorochrome detector. A cuvette tube is placed in the sample chamber, which contains an aqueous solution. This solution is used to examine a variety of biological samples, typically consisting of a suspension of cells or other particles. The sample chamber also includes a fluid pump and valves, a capillary nozzle and an entry gate. A laser, which is tuned in to a specific wavelength, is directed at the sample containing cuvette tube, causing the cells to fluoresce. Fluorescence signals produced by the cells are measured by a series of specially designed optics that have been attached to the detector. This detector is composed of two photomultiplier tubes and optical filters set to different wavelengths. The amount of fluorescence in each cell is measured and the data is used to generate a fluorescence histogram. By analyzing the data generated, the types of cells being studied can be identified and counted. This data can be used to accurately characterize the sample population being studied, making BECTON DICKINSON FACSCalibur a valuable lab tool. In addition to a laser, a cuvette tube and a detector, FACSCalibur also includes various accessories. These include a sample pre-loader, which is used to automatically load and transport the samples to the sample chamber. A sample mix-miner is also provided which can be used to mix two or more samples together for analysis. The instrument also includes a computer control system, used to control its functions and analyze the data it collects. Overall, BECTON DICKINSON FACSCalibur is a highly versatile, automatable instrument and accessories used in laboratories for the analysis of biological samples. It is capable of detecting minute physiological characteristics of cells, at a rapid rate and with a high degree of accuracy. Making it a powerful and invaluable tool for analyzing a variety of biological samples.
