  This is cool and disclaimer, I did not watch the whole video but was mostly interested in the quality control.

  There is one big reason such a device is so expensive, as for just about every experiment you need complete confidence in its precision. So a commercial device is built to provide that. This might be “less important” in an academic setting where malfunction will just annoy the postdoc, but gets a bit more important in a commercial setting where money is on the line. I guess that is not the use case for this though.

  I don’t see him do any proper QC though, showing colors looking relatively even and getting pretty gradients is nice, but there can still be considerable variation between plates or wells here that are not visible to the eye.

  I haven’t done any proper calibration myself for a while now, but usually one would use a liquid that has some light absorption that can be measured in a plate reader. So you can get actual experimental numbers for the variation between wells but also plates.

  And if he does that it would probably help a lot to compare it with the commercial device, how close is he to that standard of quality?

    (Thanks for commenting.)

    I too wasn’t convinced that the QA practice for liquid volume dispensing was very accurate. Especially for a medical device that deals with critical dose measurements.

    But I did see this as a great step forward as a ‘open(?)’ source project. There’s room for improvement and I figure there’s someone out in the world that has found or will find, a way to improve the dispensing measurement accuracy.

    And just a bit of info to go off of, I checked out his channel and found that this and the video before this published video are the only ones with over 100k views. So he’s definitely in the fine-tuning phase of his content and channel. I hope to see more of his projects in the future.
