Bio-Calculator 2.0 is a professional mobile application tailored for researchers, students, biotech developers, and laboratory professionals. More than just a toolset, it is your high-efficiency scientific assistant at the laboratory bench. 【Comprehensive Feature Modules】 1. Protein & Peptide Conversion • Precisely convert between Protein Size (kDa), Mass (mg), and Moles (nmol). • Estimate DNA/mRNA coding capacity based on protein molecular weight. • Protein Molarity conversion with built-in common protein data. 2. Nucleic Acid & Genomics Toolkit • Sequence MW Calculation: Input DNA/RNA sequences to automatically obtain molecular weight and GC content. • Molar Conversions: Switch between nucleic acid length (bp/nt), mass, and moles. • Absorbance Conversion: Quickly convert OD260 readings into nucleic acid mass concentration. • Ligation Reaction: Intelligently calculate vector-to-insert molar ratios for cloning experiments. • Nucleic Acid Concentration: Convert between mass concentration and molarity. 3. Biochemistry & Solution Preparation • Molarity Calculator: Built-in database of thousands of compounds and reagents for instant mass and concentration calculations. • Dilution Calculator: Full support for C1V1 = C2V2 calculations across various concentration units. • Centrifugation: Precise conversion between Relative Centrifugal Force (RCF/g) and Revolutions Per Minute (RPM) based on rotor radius. • Temperature Units: Covers various scales including Celsius, Fahrenheit, and Kelvin. • Molecular Weight: Calculate accurate MW based on compound formulas. • Concentration Conversion: Switch between mass concentration and molarity for solutions. 4. Microbiology & Cell Culture • Growth Prediction: Predict microbial doubling time based on two OD measurements. • CFU Counter: Automatically process serial dilution data to calculate viable cell concentration. • TCID50: Essential Tissue Culture Infectious Dose calculations for virology. • Dilution Planning: Strategic planning for colony counting dilutions. 5. Massive Buffer & Solution Preparation Library Step-by-step preparation guides for 100+ standard lab solutions: • Stock Solutions: EDTA, Tris-Cl, DTT, IPTG, ATP, HEPES, and more (includes sterilization and storage advice). • Buffer Systems: PBS, D-PBS, TAE, TBE, RIPA Lysis, Co-IP, SSPE, etc. • Each guide includes component ratios, sterilization methods (Autoclave vs. Filter), storage temperatures, and safety precautions. Why choose BioCalculator 2.0? • Native Performance: Built natively for iOS with a modern, intuitive UI and silky-smooth operation. • Industry Focused: From biotech startups to academic labs, our tools fit your daily workflow perfectly. • Global Science Calculator: Unique floating window design allows you to access scientific calculations from anywhere. • Laboratory Precision: Say goodbye to floating-point errors and embrace professional scientific accuracy.
