 The next thing we'll talk about is ejecting the tips. So we get the tip on. Like I said, I like to do the double just to make sure it's actually on. So we have our liquid and take the liquid out. And so now we've already used this tip, right? And we don't want to use it again. Unless you're using the same media or the same solution, you never really want to reuse a micropipe pet tip. So it's a way to get rid of the micropipe pet tip. So we've been using this top one to get the liquid out. For ejecting the tip, we use this one right here. In the back, there's a one right there. And this one's a little bit hard. You just have to press a little hard and then the tip comes right off. So that's how you eject a micropipe pet tip.
