About LabBench
LabBench is a growing set of free online tools for college students. It started with chemistry calculators for lab reports and problem sets, and it’s expanding into biology and general study tools.
What you’ll find here
- Calculators that show the formula and the numbers plugged in, not just the final answer.
- Pages that load fast and work on a phone at the lab bench.
- No signup and no account needed.
A note on accuracy
The calculators use standard rounded atomic weights and common textbook formulas. Always check your course’s required values and rounding rules, and confirm results with your instructor before turning in graded work. LabBench is a study aid and doesn’t replace your textbook or your instructor.
