Has anyone here used the Opentrons OT-2 for library preparation? https://opentrons.com/ot-2

"Accuracy Accurate down to 384-well plates"
This is a new measure of accuracy that I was previously unaware of.
Their only 'Sequencing Application' in their protocol library is for 16S. There are liquid handling platforms with a much wider array of NGS protocols ready to go than this.. -
A neighboring lab has the OT-One. This first version is unusable for just about anything - it can't hold the pipettes properly and the plates have a lot of play. Version two looks very different, though.Comment

There have recently been a few discussions about them on Reddit; perhaps it might be a way to get in touch with people who use them.Comment

We recently got an OT2. So far it works for single channel pipetting.
We have problems with both of our multi-channel pipettes.
The magnetic module seems to have a design flaw - the magnet is too close to the samples, even when disengaged and at maximum distance (achieved with an self-made adapter). Thus, the beads do not stay in suspension for long - ideally they should stay in suspension for 5 minutes before then engaging the magnet.Comment

Love this - good data definitely starts from good input, and poor input can only give relatively poor data. I particularly like the mention of Nanodrop/absorbance based methods for quantification. It's such a toss up if you'll get an accurate reading or what amounts to a randomly generated number, and a lot of library/sequencing related issues can be traced back to poor quant.07-01-2026, 11:43 AM

I’m not a sequencing expert. I’m a purification scientist who uses NGS to evaluate workflows my group develops. With this perspective, we think about the sample first and the NGS workflow second. The sequencer is an exceptionally honest reporter, but it can only report on what you give it, so whether you get clean, interpretable data from an NGS workflow is largely determined before you begin.
Here are nine questions we think about, in roughly the order they matter, before...
