Today, plate readers come with tools for data analysis.
Plate readers are used for:
- To monitor cell growth
- Acid quantities in chemicals
- Cell reactions
- Enzyme activity
- Cell toxicity
- Amounts of chemicals in cells
- Checking substances for drugs
Using these plate readers can help human scientists do their work more efficiently. Plate readers are used mostly in research, to find drugs, and to help test the purity of chemicals in pharmacies and laboratories.
