WebFlow cytometry is an effective tool in immunology that uses laser as a light source to yield scattered and fluorescent light signals read by photomultiplier tubes or photodiodes for detection. Flow cytometry allows immunophenotyping using fluorescently conjugated antibodies for the identification of subgroups of immune cells at a single-cell level. WebPhotomultiplier Tube (PMT) modules combine a PMT with a high voltage supply and often other signal processing electronics. A variety of PMT modules are available which differ in output signal format (current or voltage), spectral response, amplifier gain and bandwidth, as well as the size of the active area. 8mm Voltage and Current Output types feature 8mm …
