Tools / Colony counter
Colony counter
Count colonies from a plate photo instead of a marker pen and a headache.
Photograph your plate, load it into the browser and count on the image itself. Every colony you mark stays marked, so you always know where you left off and nothing gets counted twice.
Counts are saved as worksheets: reopen yesterday's plate from the sidebar, continue counting or check a number without hunting for the plate itself.
Count on the image
Mark colonies directly on the photo. The running total updates with every mark.
No double counting
Marked colonies stay visibly marked, so a crowded plate stays under control.
Saved worksheets
Every plate is a worksheet you can reopen, rename and continue later.
Runs in the browser
No install, no license. Works on the lab PC and on your laptop alike.
How it works
- Photograph the plate and load the image.
- Click colonies to mark and count them.
- Save the worksheet and reopen it any time.
Who is this for?
Researchers, students and lab teams who want the routine arithmetic and paperwork of bench work handled, without installing anything.
Frequently asked questions
Does it count automatically?
No. You mark each colony yourself and the tool keeps the count, the marks and the image together. We would rather be honest than approximate.
Can I recount a saved plate?
Yes. Every count is a worksheet; reopen it and continue exactly where you stopped.
Is it free?
Yes. LabBee is in beta and every tool is free. If paid plans ever arrive, we will say so clearly ahead of time.
Do I need to set up a lab?
No. Every tool works with just an account. The lab modules are there when your group wants them.
Is my work saved?
Tools that produce documents save them as worksheets you can reopen from the sidebar. Quick calculators simply give you the answer.
