Stop wasting precious samples on arithmetic mistakes. LabConvert is the go-to scientific calculator app for molecular biology, cell biology, biochemistry, and virology labs, instantly solving the repetitive calculations that slow down your research workflow. Built exclusively for life science researchers, graduate students, lab technicians, and educators, it consolidates essential bench tools into one clean offline interface, eliminating manual errors in reagent preparation, reaction setup, and data analysis so you can focus on experimental design and discovery. Precision Calculators for Your Complete Workflow LabConvert delivers specialized calculators covering molecular cloning, cell culture, and virology protocols. Each tool is crafted for real-world bench work, generating copyable results in a single tap. - PCR Master Mix Calculator : Compute primer, template, master mix, buffer, and water volumes effortlessly. Customise reaction counts, add overage factors, and edit component lists to produce a ready-to-use recipe. - qPCR Quantification : Determine relative gene expression via standard curve or delta delta Ct methods. Supports custom thresholds, efficiency correction, and replicate handling for robust quantification. - Virus Titer Calculator : Switch between PFU and TCID50 modes. Input multiple dilutions and let the app calculate the final titer automatically. - Cell Culture Calculator : Manage seeding density, cell counts, passaging ratios, and culture volumes for both adherent and suspension cell experiments in one place. - Buffer and Media Preparation : Enter stock concentration, target concentration, and final volume to obtain required stock and solvent volumes instantly. Handles 10x, 5x, 50x, and other common dilution factors. - Centrifuge Speed Converter : Translate RCF to RPM and vice versa using rotor radius, compatible with diverse centrifuge models. - Primer Dilution Calculator : Find the exact water volume needed to resuspend or dilute primers from stock to working concentration. - Standard Curve Tool : Input concentrations and optical density readings to generate a standard curve and quantify unknown samples. - Transfection Calculator : Supports Lipo2000, Lipo3000, PEI, and custom reagents. Quickly determine recommended DNA and reagent amounts for your setup. - Serial Dilution Assistant : Generate equal-ratio and gradient dilutions with clear concentration and transfer volumes for every tube. Built-In Formula Reference Library Access a pocket reference of frequently used life science formulas without textbooks or browsers. The library covers molarity conversion, unit conversion, OD260/OD280 nucleic acid quantification, and radioisotope decay calculations. Whether you are preparing reagents inside a biosafety cabinet or verifying numbers before a group meeting, reliable answers are just a few taps away. Localised and Personalised Experience LabConvert adapts to lab users worldwide with Chinese and English interfaces and automatic locale detection. Customise decimal places for results in Settings, and copy any calculation output to the clipboard with one tap for pasting into lab notebooks, Excel spreadsheets, or group chats. Clean, Stable, and Fully Offline Designed for unreliable lab networks, every calculator operates completely offline. The dark-themed interface reduces eye strain during long bench sessions, and the layout is optimised for both iPhone and iPad, ensuring efficient computing wherever you work.
