Chemical Dilution Calculator
A stock bottle says 10%, the protocol wants 1%, and the batch has to come out at exactly 1,000 mL.

Cost Per Test Calculator
Every testing program has a total bill and a test count, and the ratio between them decides whether the program is efficient, underpriced, or quietly leaking money.
-
Mass Accuracy Calculator
A mass reading is only useful if you know how close it sits to the real value.
-
Laboratory Productivity Calculator
A laboratory can finish thousands of tests and still not know whether the team is getting more efficient or just working longer.

Test Tube Volume Calculator
A test tube is a cylinder, so its volume is base area times height, but at the bench nobody measures in centimeters of radius.

Chemical Dilution Calculator
Works out how to dilute a stock solution to the strength and volume a protocol needs.
Use calculatorThis is a small, practical set: the Chemical Dilution Calculator works out how to prepare a solution at the right strength, the Test Tube Volume Calculator sizes the vessel to the sample, and the Mass Accuracy Calculator checks how close a measurement is to the true value, while the Cost Per Test Calculator and laboratory productivity cover the running of a lab itself — what each test costs and how much work the lab gets through.
