About 90% of my spray nozzles are from Adam's and came with the bottles and I still have about 15 or so of the Pre-Covid nozzles, which are excellent.
If you are looking for something for the small bottes, go to your local hobby store, they generally have a good variety and decent prices. Many of them are made for handling paint and solvents, so the chemicals work fine with them.
If you like nozzles that do more of a mist, then look at the beauty/barber shop suppliers and if you like sprayers than fan out rather well check out your local plant nursery, not the ones in the big box stores, but the ones that actually sell the plants and supplies. Word of advice, don't take the ones your wife bought for misting her plants - no need to ask me how I know that.
Finally, if you want something you can drop on the floor and don't have to worry about breaking, check out the Grainger Tough Guy series of spray nozzles. Don't cry when you see the cost of them.
