MicroBlue slides are glass microscope slides loaded with a mix of Methylene-Blue and Cresyl-Violet for staining and morphology assessment of cells. MicroBlue slides allow quick visualization of sperm-head, acrosome and tail. World Health Organization and Kruger strict morphology assessments can be done using MicroBlue. The slides are also useful in microscopy of any cells or bacteria. MicroBlue slides can be used for the evaluation of cells in whole blood, urine, milk and vaginal-smears. The slides are suitable for differentiation of white blood cells in peripheral blood, cytology of body fluids and evaluating sperm head acrosome size. The slides generate consistently high quality cell staining efficiently.
