Calculation method
Calculation method
Balanced opposing-pair run proposal
Split samples at max fill; each sample tube paired with identical-mass balancing tube under common-density assumption; return run,slot,sample index,fill mL,balance slot.
Run count
Ceil sample tube count/(slots/2)); conservative separate counterweights, no cross-sample pairing.
Counterbalance liquid mass (g)
Total paired counterweight volume×supplied common density.

Assumptions & limits
Assumptions & limits
- Arithmetic opposing-pair proposal for an even-slot rotor using a separate identical-mass counterweight for each sample tube. Tube tare masses must match; manufacturer balance limits and approved configurations remain external. 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. Sample volumes (mL): minimum 1e-12, maximum 1000000000000.0. Maximum tube fill (mL): minimum 1e-12, maximum 1000000000000.0. Even rotor slots: minimum 2, maximum 64. Assumed common liquid density (g/mL): minimum 1e-12, maximum 1000000000000.0.
