Kova Plastics by Alltrista Glasstic Slide II Gridded. Made from optically clear plastic. Each Slide ll features four individual fully segregated specimen wells. Integrated counting grids. Slides that include integrated counting grids provide results that have high correlation with results obtained with precision hemocytometers. Capillary action reduces the likelihood of pipetting errors. Suspends sediments homogeneously throughout the specimen. Eliminates other variables, providing precise, reproducible fluid distribution throughout each chamber. Reproducible fluid distribution throughout each chamber. Chamber walls prevent specimen leakage and cross-contamination. UOM: 100/BX.
