MAC Master Slide
In stock
The McMaster slide is a specialized microscope slide used in veterinary medicine to perform Quantitative Fecal Egg Counts (FEC). It allows animal health practitioners to rapidly determine the number of parasite eggs or oocysts per gram of feces (EPG), measuring the severity of gastrointestinal infections and verifying if deworming treatments are effective.

To use the slide, a fecal sample is weighed, mixed with a specific flotation solution (such as sugar or sodium chloride), and strained. This process separates parasitic eggs from large debris. The suspension is then pipetted into the slide's chambers and left to sit for a few minutes so the eggs float to the top. Viewed under a standard compound microscope at 10x magnification, the floating eggs are counted within the grid lines.

- Two or Three Chamber Design: Most standard slides contain two chambers, with a holding capacity of 0.15 ml per chamber, allowing for duplicate testing and high accuracy.
- Durable Construction: Modern McMaster slides are often made from thick, optical-grade acrylic or polycarbonate, fused together using sonic welding, which prevents leakage and sample contamination.
- Reusability: Unlike traditional glass slides and cover slips, McMaster slides are designed to be easily rinsed with warm water, making them highly cost-effective for repeated, long-term use.
