Unit-aware inputs
Units are explicit UI elements, not buried in placeholder text.
-
Research use only
Not for clinical decisions. Designed for research and education.
Frequently asked questions
What is BiomeBench?
BiomeBench is a free, static web platform of professional biology and laboratory calculation tools: 13 calculators for solution preparation, cell culture, PCR, quantification, and experimental planning, plus a 96-well experiment planner, an inventory tracker, and reference tables.
How accurate are the calculators?
Every calculator runs on a published formula that is shown on its page, with inputs, units, assumptions, and limitations stated in visible text. Each calculation engine is checked against an independent verification suite before release. You should still verify results independently before critical use.
Is my data stored or sent anywhere?
No. Calculations run entirely in your browser. The planner and inventory save only to your device's local storage, and nothing you enter is sent to a server. There are no accounts to create.
Who is BiomeBench for?
Researchers, students, technicians, and lab professionals who do bench calculations daily. The tools are intended for research and educational use, not for clinical or diagnostic decisions.
Which languages is BiomeBench available in?
The entire site — every calculator, explanation, and FAQ — is available in English, Spanish, Japanese, French, German, Portuguese, Korean, and Italian.
