Good question! I work in the research area, so it will really depend on what we’re trying to do. If its just look at whether a given mixture will make a good tablet, then we might only make one. If we’re trying to check whether the machine works well continuously it might be a lot more. The tablet producing machines are very cool, the ones I use can make 800 tablets per minute!
Nothing compared to what it could be though… on a bigger commercial machine it would be even more, like 1,000,000 per hour(or 16,000 per minute, 270 per second…)!!!
