Karam Study Desk
A defined experiment, a comparable lab scope and a usable handover.
A local calculator that separates samples, billable determinations, laboratory costs, analysis, management and contingency. No data leave your browser.

No costs are fetched from vendors. A zero field means you entered no cost, not that the service is free. Tax, discounts and financing are not modeled.
This is not a power calculator. Repeated measures on the same biological unit need a different design; they are not independent samples. The tool does not advise how many samples make a study scientifically valid. Use the sample-size sketch only for its stated statistical assumptions and obtain qualified study-design advice.
A defined experiment, a comparable lab scope and a usable handover.
Multiple readouts. A defined model. An interpretable result.
