Laboratory workflow need
Users often need to seed cells into plates or dishes at a target density. A calculator should help determine the required cell suspension volume, culture medium volume, and total preparation volume based on cell concentration, target seeding density, number of wells, and plate format.
Required inputs
- Current cell concentration
- Target cells per well or target seeding density
- Plate format
- Number of wells
- Final volume per well
- Extra volume percentage or fixed extra volume
- Cell concentration unit
- Volume unit
Expected outputs
- Cell suspension volume needed
- Culture medium volume needed
- Total preparation volume
- Total number of cells required
- Volume per well
- Warning messages for invalid or very small volumes
Formula or calculation rules
Total cells required = target cells per well × number of wells
Total preparation volume = final volume per well × number of wells × (1 + extra percentage)
Cell suspension volume = total cells required / current cell concentration
Medium volume = total preparation volume - cell suspension volume
Units
Cell concentration: cells/mL, cells/uL
Volume: mL, uL
Plate format: 6-well, 12-well, 24-well, 48-well, 96-well, custom
Validation rules and warnings
- Current cell concentration must be positive
- Target cell number must be positive
- Number of wells must be positive
- Final volume per well must be positive
- Extra percentage cannot be negative
- Medium volume cannot be negative
- Warn if cell suspension volume is very small and difficult to pipette accurately
Example calculation
Current cell concentration = 1,000,000 cells/mL
Target = 100,000 cells per well
Number of wells = 6
Final volume per well = 2 mL
Extra volume = 10%
Expected output:
Total cells required = 600,000 cells
Total preparation volume = 13.2 mL
Cell suspension volume = 0.6 mL
Medium volume = 12.6 mL
References or notes
Initial implementation should focus on transparent calculation logic and unit tests. Plate layout UI can be added later.
