About This Product
The shallow well in a cavity slide lets a drop of pond water or culture be viewed without a cover slip pressing on it, so motile organisms keep swimming. It is used for the hanging-drop method and for watching reactions that happen in a small volume of liquid.
Frequently Asked Questions
What is the Cavity Slide used for?
