Optocoupler suggestions

IIRC about a 40%-50% discount.

As I recall they want to make 40% of the selling price.

That doesn't seem too out of line. We have a few things that other people make and we resell them... for one we make ~$1.5k out of ~$5k... ~30%

Nice markup! Of course the Varian NMR business imploded (or something) a few years ago. I always feel weird charging too much for commercial stuf f that people can go buy themselves elsewhere.

Agilent acquired Varian and immediately killed the FTMS line. A bit later they killed NMR. We were suppliers of electronics for both.

Both technologies needed a giant superconductive magnet, and have probably been killed off by stuff that doesn't. I have been in labs that have hundreds-of-kilobuck magnets sitting collecting dust at room temp; I think it's just too expensive to keep buying liquid helium.

The medical MRI people can afford to run the magnets, and are lately using local reliquifiers instead of letting the boil-off escape.

At one point in my grad school days, I was being paid on some research/capitol equipment line, to keep the whole liquid helium recovery system working at UB. It was a nightmare! ~100 valves and if someone left one open all that days helium would leak out. There was a ~20'x20'x10' rubber balloon that would collect and then trip on, I think it was a level/ height contact, with pressure sensor backup but that might be backwards. (Doing maintenance on the He liquifier was the fun part, well and then running it... though it meant sleeping over in the lab, I don't think I showered nearly enough when I was younger.)

Some closed cycle system seems the way to go these days, given He prices. (I've been out of the helium game for ~20 years.)

People used to say that liquid nitrogen cost the same as beer, and liquid helium cost the same as whiskey.
