The Scepter 3.0 cell counter provides the unparalleled precision of Coulter impedance counting in a convenient, handheld format. Our newest version of the popular Scepter cell counter has been updated with features that make it more convenient, easy-to-use, and accurate than ever before. The Scepter sensors use precision microfluidics to measure the electrical impedance of individual cells. This technology gives on-demand outputs of cell volume, cell diameter and cell concentration──all within the cell culture hood. The smartest version yet of our handheld cell counter, the Scepter 3.0 instrument uses the Coulter impedance method which avoids common artifacts arising from image-based cell counting methods. It does not rely on user technique or manual calculation for accuracy and counts thousands of cells per measurement for maximum precision.
