 In our program, we principally use this clinical tabletop centrifuge for cell culture. And you can see I have it fitted here with two types of carriers, one for the 15 mil centrifuge tube and one that would hold the 50 mil centrifuge tubes. You can also see by standard practice that the 15 mil carriers are placed opposite each other and the 50 mil carriers are placed opposite each other. It's very important in centrifuge operation that you consistently have the rotors balanced so you would not want to place different sized tubes or different types of carriers opposite each other. Because the 15 mil carriers are meant to be balanced with 15 mil tubes and the 50 mil tubes carriers should be matched also. This, as you can see, is a swing bucket rotor so that these swing, they have the removable buckets or tube carriers that fit into these rings. We call these rings trunnion rings. And so this is, like I say, this is a typical centrifuge for handling cells. Here we have just a bucket off of a swinging bucket rotor. I didn't bring the whole heavy rotor here, but this is one of four buckets that go on the centrifuge and you can see this bucket is specifically made to carry a conifold bottom plastic centrifuge bottle. So that the carrier is conifold and there's even a conifold adapter that is in there so that it's very important with these conifold tubes that this adapter supports this cone because with the force on this tip it could easily compress that tube if it weren't supported. Here's another bucket from that same centrifuge. It's just a standard open bucket that would take either a large bottle or a wide variety of those adapters. And I've just included one particular adapter here just to show you a centrifuge bottle. We're not just working with tubes, we just saw the conifold centrifuge bottle and this is a centrifuge bottle. You can see it's made out of a plastic capable of handling at high speed and it has even a gasketed cap so that the actual liquid in any that's in there helps contain it.
