Microscope Slide McMaster Green Grids

Special compartmentalised slide for counting the number of stomach worm eggs in faeces from cattle, sheep, horses and other ruminants.

This allows evaluation of the efficacy of the worm drench or drenching program being used, and also the likely pasture contamination in a given area. Ideally used with 10X objective microscopes. 

The green printed slide makes for considerably easier recognition of grid lines. Slide can be cleaned and reused. Instructions for use are included.
