I agree with Beth Wing, sounds like there is some confusion about
juice delivery device terminology going on here.
"Cartridge
tanks" are kind of old school as far as
juice devices go, but I'm aware that a lot of starter kits still come with them, and many vapors continue to use them. These combine two pieces: an atomizer and a tank end to end. Other than that, I'm not very familiar with them having never used one.
Generally speaking,
a drip tip is often used simply as a mouthpiece for a variety of juice devices, from cartomizers and cartotank, some clearomizers, drip atomizers, and RBA's.
For a little more clarity in terminology of juice delivery devices, I've written an article of the more common ones in my blog:
