Laboratory passage split arithmetic calculator

Calculate branch cell and full-vessel allocations and unallocated source cells with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use branch cell and full-vessel allocations and unallocated source cells to compare changes to your inputs. The method and limits below explain the scope.

Examples

Examples

Try the starting example

Available cells
1000000
Split fractions to branches
0.5,0.3
Target cells per full vessel in each branch
100000,100000
Branch cell and full-vessel allocations
[[0,500000,5,0],[1,300000,3,0]]
Unallocated source cells
200000

Try another scenario

Available cells
1000001
Split fractions to branches
[0.5, 0.3]
Target cells per full vessel in each branch
[100000, 100000]
Branch cell and full-vessel allocations
[[0,500000,5,0],[1,300000,3,0]]
Unallocated source cells
200001
Calculation method

Calculation method

Branch cell and full-vessel allocations

Floor available×branch fraction; full vessels=floor(branch cells/target); return residual branch cells.

Unallocated source cells

Available minus all branch allocations; sum fractions≤1.

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • Available cells, specified split ratios, vessel targets. Returns Vessel allocations and remaining cells. All coefficients and observations are user supplied; results describe only the stated mathematical model. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification. Available cells: minimum 0, maximum 1000000000000. Split fractions to branches: minimum 0, maximum 1. Target cells per full vessel in each branch: minimum 1, maximum 1000000000000.
