Project Description

Flow Cytometry Calibration Microspheres

Our flow cytometry calibration microspheres have great fluorescence intensity and a wide emission spectrum in multi-channel (FITC, PE, PE-Cy5), which is ideal material used to monitor routine calibration of flow cytometer. Our perfect microsphere counting technology and homogeneous internal dyeing process ensure the test results by the flow cytometer are highly reliable.Our flow cytometry calibration polystyrene microspheres used extensively for QC and long term performance tracking of flow cytometer.

They can also be used for routine alignment and calibration in fluorescence and confocal fluorescence microscopy.
