Simplify your lab calculations with Lab Calculator

In your routine work in the lab you prepare stock solutions, use prepared stocks, and play around with various unit conversions. That means you should be competent with basic lab math, which is not too hard. but it is too important and you don’t want to make mistakes in a stock you will be using for the next three months. The Lab Calculator is a small utility that helps you with these basic calculations. You can

• calculate the mass of a chemical required to make a stock solution of your choice
• calculate the final concentration achieved by dissolving a given mass in a given volume of solvent
• perform a basic dilution
• perform the famous C1V1=C2V2 calculation (where C1 is stock concentration and V1 is volume of stock, and C2 is final concentration and V2 is final volume).

You can even get help with handling basic ratios like how much water to add to 346ml of 95% ethanol to get 70%. The Lab Calculator is free, and the current version is 1.30. Since it is developed by yours truly, you can email me with comments. Click here to visit the Lab Calculator homepage.
