Chemistry Tools is a comprehensive app designed to support organic chemists, students, and lab professionals with powerful calculators, quick references, and essential data at your fingertips. All data is in one app and usable without an internet connection (except external link references).
Please note: this app is not a periodic table—it's a comprehensive toolkit for lab calculations and chemical information, covering areas that go beyond elemental data.
The main idea of this app is to have a single-point resources to quickly find desired information and to improve efficiency during lab work. The app is built for a fast and easy navigation with an intuitive design.
Key Features:
- Azeotrope Checker
Quickly check azeotropic data for binary solvent mixtures (or ternary with water), helping you identify azeotropic mixtures with ease and understand their boiling points and composition for efficient distillation processes.
- Dilution Calculator
Simplifies preparing solutions by calculating the exact volume of stock solution needed, making your dilutions faster and more accurate.
- Hazard & Precaution Statements (H, EU, P Statements) and Pictograms
Access all european hazard and precaution statements, along with corresponding EU and GHS pictograms, for safe handling.
- Heating and Cooling Bath Mixtures
Quickly find baths for a desired temperature.
- Organic Solvents Information
A table of commonly used solvents in organic chemistry, including key properties like boiling point (°C), melting point (°C), density (g/mL), solubility in water (g/100 g), relative polarity, dipole moment, dielectric constant and Viscosity (1/1000 Pa s).
- Percent to Molar Concentration Calculator
Easily convert percent concentration to molarity.
- Polarity of Solvents Table & TLC Revelators
Reference solvent polarity and recipes for Thin-layer chromatography revelators for chromatographic analysis, enhancing separation efficiency and visualization.
- Rotavapor Pressure and Temperature Calculator
Calculate optimal pressure and temperature settings for your rotary evaporator, improving solvent removal rates and ensuring safe operation.
- Solid Mass for Stock Solution Calculator
Determine the exact mass of solid required to prepare a desired concentration in solution, aiding in accurate stock preparation.
- Solvent Group Table
Solvent groups are a classification scheme according to Snyder in which solvents are placed in groups of similar selectivity/chromatographic properties.
- Solvent Peaks of 1H and 13C NMR Table
Quickly look up common solvent peaks in both proton and carbon-13 NMR, making NMR analysis easier.
- TLC Eluent Translator
Translates Thin-layer chromatography eluents to various solvent ratios, allowing you to switch between systems.
- Typical Chemical Shifts in 1H and 13C NMR
A quick reference for common chemical shifts in NMR spectroscopy, helping you interpret spectra and confirm compound structures.
- UN Numbers and Hazmat Placards
Access UN numbers and hazmat placards for information purposes and i.e. identifying chemicals by the number displayed on a delivery truck.
- Web Resources
Links to trusted chemistry web resources and databases for deeper research, including safety guidelines, solvent data, and chemical information.
And more tools, like common abbreviations, yield calculator with regards to purity and stoichiometry, degree of unsaturation calculator also calculating possible unsaturation combinations (number of rings, double bonds and triple bonds), molar mass calculator and more!
All tools have help modals to facilitate understanding.
More tools will follow. If you have any requests, suggestions, ideas, etc., feel free to contact us at [email protected].
