How It Is Used
Living protozoa, algae and small invertebrates such as rotifers or Daphnia can move in the cavity without being crushed by a cover slip. For the hanging-drop method, a drop of culture is placed on a cover slip and inverted over the cavity, so bacterial motility can be watched while the drop is protected from evaporation. The cavity also holds small reagent volumes for micro-scale reactions.
Frequently Asked Questions
How is the hanging-drop technique done with the Cavity Slides (Pack of 10)?
A drop of culture is placed on a cover slip, which is then inverted over the cavity. Bacterial motility can be observed while evaporation and contamination are prevented.
Why are the Cavity Slides (Pack of 10) thicker than plain slides?
They are 1.2–1.5 mm thick, a thicker base that accommodates the concave cavity.
