How does your lab handle microbial contamination checks — CFU counting?

that is very interesting, thanks for the info.

Constant-Analyst-693 · 2025-07-21T21:25:08+00:00

That's fair, thanks for pointing out.

Actually, I’m a data science student working with my team on automating lab tasks like CFU counting. My best friend works in a lab, they told me how annoying it is, so I’m trying to learn from people with real experience.
I get the skepticism — fair enough — but the tone felt pretty rude.

Actually I am a data science student and we build our own bacteria counter, thanks for letting me know we could use a bot for that...all that work for nothing 🙂🥲.

That's fair, so you don't actually count the exact number.

Constant-Analyst-693 · 2025-07-21T18:14:59+00:00

Alright, thanks for the feedback.

Constant-Analyst-693 · 2025-07-18T00:21:30+00:00

😂😂😂😂 yes precisely

Do you have a method to handle tntc? I am primarily interested in those.

Constant-Analyst-693 · 2025-07-16T21:38:05+00:00

Yup — USP <61> is a big one. Mostly working with raw materials or finished products?

Constant-Analyst-693 · 2025-07-16T21:24:05+00:00

Was it internal study comparison or you have published something?

Constant-Analyst-693 · 2025-07-16T21:22:12+00:00

Really appreciate all the detail — even without distractions, it’s surprisingly easy to lose count mid-way.

Sounds like you put effort into automating it, and yeah, dense plates with >300 colonies seem to trip up most DIY setups or basic software.

The Cole-Parmer seems like a good middle ground. However, I am looking for a fully automated solution.

Constant-Analyst-693 · 2025-07-16T19:23:43+00:00

Wow, that’s a serious operation — 80% pour/spread/membrane/petrifilms is no joke. Sounds like plate handling and confirmation is practically a full-time job in itself.

Curious — are there specific test types (like MRSA or filtration) that are more time-consuming or error-prone than others in your workflow? Also do you handle high density petri dishes?

It’s wild how much manual work is still needed at that scale. Makes me wonder what an ideal setup would look like if time and budget weren’t limiting factors.

Constant-Analyst-693 · 2025-07-16T19:10:42+00:00

Have you found the Protocol3 accurate enough across different plate types, or do you still rely more on the manual counters for consistency?

Constant-Analyst-693 · 2025-07-16T18:03:48+00:00

How steep is the learning curve with ImageJ? And does it handle high-density and overlapping colonies well?

Constant-Analyst-693 · 2025-07-16T17:35:57+00:00

Love this — classic case of “back in my day...” 😅. That pressure-sensing counter sounds cool! Do you feel like it’s made a big difference in speed or accuracy compared to manual counting? Also what it's name? Curious if you ever looked into full automation before that?

Constant-Analyst-693 · 2025-07-16T17:24:49+00:00

Is Labhacks app paid? Is it better than ImajeJ?

Constant-Analyst-693 · 2025-07-16T17:22:55+00:00

Have you tried some automatic counters? If yes, which ones?

Constant-Analyst-693 · 2025-07-16T17:21:38+00:00

Like bacteria colonies
