Definition of hypotonic in English:
1Having reduced pressure or tone, in particular.
- Vasopressin continued to act in patients excreting isotonic or hypertonic urine, so hypotonic intake must be avoided in them.
- However, in vivo sampling methods lead to the stimulation of a relatively hypotonic glandular secretion.
- A potential limitation of the presented methods is that pressure-flow measurements were generated under hypotonic conditions.

- Thus, the photodamaged lysosomes and the normal ones will suffer the same level of osmotic stress in the same hypotonic sucrose medium.

- Example sentences
