Bioreactor Oxygen Transfer: kLa, OTR and Max Cell Density
Wired White v2 Calculate oxygen solubility, kLa, OTR, oxygen demand and dry biomass limits. Compare oxygen capacity with jacket cooling duty and explore an animated dissolved-oxygen transient.
Agarose Gel Simulator: Percent, Run Time, Band Positions
Wired White v2 Choose agarose percentage, estimate DNA band positions and run time, and mix a gel recipe. Animate the run or calibrate the approximate mobility model to your ladder.
Bacterial Growth: When Does My Culture Reach OD600 0.6?
Wired White v2 Estimate time to an induction OD600 from starting OD, doubling time and lag. Compare Gompertz and exponential growth, size the starter, and check measurement dilution.
Primer Tm and PCR Annealing Temperature Calculator
Wired White v2 Calculate DNA primer melting temperatures with nearest-neighbor thermodynamics and Mg²⁺/dNTP corrections. Compare a primer pair, view melting curves, and plan a gradient PCR.
qPCR Efficiency Calculator: ΔΔCt and Pfaffl
Wired White v2 Analyze Ct replicates with ΔΔCt and Pfaffl, geometric reference-gene normalization and propagated error. Fit standard-curve efficiency and calculate DNA copy numbers.
Cell Culture Planner: Count, Doubling Time, Confluence Day
Wired White v2 Turn hemocytometer counts into viable cells/mL, fit population doubling time, and plan how many cells to seed for a chosen confluence day.
Centrifuge RPM to RCF Calculator, k-Factor and Pelleting Time
