From Zoos in Africa, to preserves in Mongolia; from studies on whales in the Pacific to Arctic foxes; from olive groves in Greece to corn farms in Iowa; from Kentucky horse farms and Texas goat herds to Australian sheep stations – our counting slides have helped answer the questions you have in your animal and farm research. There may be other slides available, but none as accurate. It is very important to use a precisely made slide because the grid on the slide and the volume under the grid are what produce accurate and consistent results. There is an exact quantitative relationship between the volume under the grid of the slide and the formula for mixing fecal matter with flotation solution. Our slides are manufactured to exact standards in order for the Egg Per Gram results to be correct. We have seen imitations of our slides where the grids are sloppy or fuzzy and the volumes vary from slide to slide. We have been manufacturing counting slides since 1980, and our first customers were the veterinary teaching colleges in the U.S., Australia, and New Zealand. Please do not accept anything less than the best made slides. The health and thriftiness of your stock depends on it. We offer a few key, proven designs which makes product selection and ordering easy. We look forward to hearing from you and having you as another satisfied customer. And a big thank you to those of you who have been with us for over 35 years!
