ABSTRACT:
A magnetic slide loading is used with automated cell counting equipment or manual optical microscopes to measure the number of cells in a fluid biological sample. A slide having a defined volume region holds the sample for measurement. A cover slip is placed over the defined volume region creating an enclosed volume. An actuable holder clamp is placed over the slide securing it as well as the cover slip in position by virtue of magnets secured to the bottom of the device exerting a magnetic force upon the holder clamp such that it is attracted toward the slide forcing the cover slip to flatten, thereby removing any defects or distortions from the volume. This action ensures that the volume has a uniform depth allowing accurate measurement of cell concentration within the biological sample.
