Grading Gels According To Size

I’m reading a lot on here about grading your gels according to size… and I get why it’s important, especially with tight bore inner barrels.

I’ve been measuring sh*t professionally all my life, and I haven’t got a clue how to efficiently size grade a flexible ball that’s mostly water :joy: I’ve seen Low Guido measure with vernier calipers, but only on sample batches, that ain’t gonna wash with a couple of thousand. :thinking:

So how do you grade your developed gels? Enlighten me please :joy:

You could drill some holes in something at the correct size like a hopper or something
