Have you ever seen pipet in one science textbook and pipette in another? If so, you’re not alone. Many students, researchers, laboratory technicians, and science writers wonder whether these words describe different tools or if they’re simply different spellings of the same thing.
The confusion often appears when reading laboratory manuals, scientific papers, product catalogs, or educational materials from different countries. Some manufacturers use pipette, while others use pipet, making it difficult to know which version is correct. The good news is that both spellings refer to the same laboratory instrument used to measure and transfer liquids accurately.
This guide explains the difference between pipet and pipette, where each spelling comes from, which one is preferred in American and British English, and when you should use each version. By the end, you’ll know exactly which spelling fits your audience and how to avoid common writing mistakes.
Pipet or Pipette – Quick Answer
Quick answer: Both pipet and pipette are correct spellings for the same laboratory tool used to measure and transfer liquids.
- Pipette is the traditional and internationally preferred spelling.
- Pipet is a simplified American spelling that appears in some scientific writing and laboratory manuals.
Examples
- The technician filled the pipette with 5 mL of solution.
- Please clean the pipet before using it again.
Both sentences are correct, although pipette is far more common worldwide.
The Origin of Pipet or Pipette
The word pipette comes from the French word pipette, meaning a small pipe or tube. Scientists adopted the term during the 19th century as laboratory equipment became more standardized.
Over time, some American scientific organizations simplified the spelling to pipet. The goal was to make scientific terminology more consistent with simplified English spelling.
Today:
- Pipette remains the original French-derived spelling.
- Pipet became an accepted American variant used by some laboratories and manufacturers.
Although both spellings exist, pipette remains the dominant choice across scientific publications worldwide.
British English vs American English Spelling
The biggest difference is regional preference rather than meaning.
| Feature | Pipette | Pipet |
| British English | ✅ Preferred | Rare |
| American English | Very common | Accepted variant |
| Scientific journals | ✅ Most common | Sometimes used |
| Medical laboratories | ✅ Standard | Occasionally used |
| International publications | ✅ Preferred | Less common |
British English
British English almost always uses pipette.
Example:
The laboratory assistant calibrated the pipette before the experiment.
American English
American English accepts both spellings, although pipette is still more common today.
Example:
The technician replaced the disposable pipet tip.
Which Spelling Should You Use?
The right choice depends on your audience.
Use pipette if:
- You’re writing internationally.
- You’re publishing research.
- You’re writing for universities.
- You’re creating educational materials.
- You’re writing for British or Commonwealth readers.

Conclusion
Choosing between pipet and pipette is mostly a matter of regional preference rather than correctness. Both words describe the same laboratory tool used to measure and transfer liquids with precision. The difference lies in spelling, not function.
The traditional spelling, pipette, comes from French and remains the standard choice across the United Kingdom, Canada, Australia, and most international scientific publications. Although pipet is an accepted American variant and still appears in some laboratory manuals and technical documents, it is much less common than pipette today.
If you’re writing for a global audience, publishing scientific work, creating educational content, or simply want the safest option, pipette is the best choice. If you’re working within an American laboratory or following a specific institutional style guide, pipet may also be appropriate. Whatever spelling you choose, stay consistent throughout your document. Consistency improves readability and helps maintain a professional appearance in scientific and academic writing.
