Bio vs LabConvert

Bio-Calculator brings everyday life science calculations to your iPhone and iPad. Designed for researchers, students, and laboratory professionals, it covers solution preparation, nucleic acid and protein conversions, manual counting, and cell seeding calculations. SEE THE CALCULATION Supported calculators show the formula and substituted values below the result. Copy the calculation steps for your lab notes, check your method, or use them when preparing a report. MANUAL COUNTING A dedicated Count tab supports multiple counters, custom labels, increment and decrement controls, and counting history. Turn sound and haptic feedback on or off, and transfer counting data to CFU or cell density calculations to avoid entering it again. CELL DENSITY AND SEEDING Calculate cell density and viability from your hemocytometer counting area, number of squares counted, live and dead cell counts, and dilution factor. Add the suspension volume to calculate the total viable cell count. Use your seeding target to calculate the required cell suspension and medium volumes. Enter the overall dilution factor directly, or calculate it from the factor per step and number of dilution steps. NUCLEIC ACIDS AND PROTEINS • Convert mass, amount in moles, and concentration for DNA, RNA, and proteins. • Calculate nucleic acid sequence molecular weight and GC content. • Convert OD260 absorbance readings to nucleic acid concentration. • Calculate vector and insert amounts for ligation reactions. • Estimate DNA and mRNA coding capacity. SOLUTIONS AND UNIT CONVERSIONS • Molarity, mass concentration, and solution dilution calculations. • Molecular weight from a chemical formula. • Relative centrifugal force (RCF) and rotational speed (RPM) conversions. • Temperature conversions and a scientific calculator. MICROBIOLOGY AND VIROLOGY Tools for CFU calculations, colony-counting dilution planning, bacterial growth and doubling time, and TCID50 calculations. LAB SOLUTION RECIPES Find preparation methods for buffers and stock solutions such as PBS, TAE, TBE, Tris, and EDTA, with relevant sterilization, storage, and handling notes. Available in English, Simplified Chinese, and Traditional Chinese. Some features require an in-app purchase. For research and educational calculations. Check input units, counting chamber specifications, and experimental conditions before using results. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
