Transcription of STA Compact Operations: Replacing the Cleaning Solution

Welcome again to BioMed Buddy. We are now going to change the cleaning solution bottle. The bottle that is firmly on this system is probably full, and we are just going to simulate it, but you should get the general way of changing a cleaning solution bottle. Just for grins and giggles, we're going to hit "Escape", then hit "Status", and we're going to go to "System", and we're going to hit "Enter", and you see washing solution on this at this particular point is 2480.

(Slide, :36)

The System Status Menu informs you of the status of many areas.

The 2480, how that counts down is from action of the Valcore pump. Each time it pulses, it takes so much away from that value, and the point here if the Valcore isn't pumping enough, you'll have excessive amounts of cleaning solution left in your bottle. If you find that you're getting the air cleaning solution out prior to that reaching 0, then it's cleaning too much which is not a problem at all. In fact, I generally set my Valcore pumps high and so do other Stago reps.. That just means that it's cleaning a little better. Regardless of that, let's change the cleaning solution.

Valcor Pump is easy to check. See video in Maintenance/Checking the needles and valcor pumps.

I just mention that because again if you do find that it says that you are low and you are not, that's an indication of your needles either being clogged or your Valcore pump isn't putting out adequate amount, which is a concern. Let's continue with changing this. Hit "Escape", I'm going to "Quit", I'm going to "Escape", I'm going to go over to "Loading". "Loading", "Enter", go down to my washing solution. Hit "Enter". It says, again read the screen, "Please remove and throw out this bottle."

Following the prompts from the screen is the best wayto change the Wash Solution Properly.

That's the waste bottle. Let me move this over a little so you can get a clear picture of it. Over the right-hand side door. This is the waste bottle. This is the waste adapter up top. You see it's got a sensor on it that tells you when the waste is full. And this is the cleaning bottle.

(Slide, 2:27)

Recommend you date the new Cleaning/Washing Solution Bottle and write Waste on the waste bottle.

I'm going to tell you, I am one of those people that believes in labeling these "Cleaning Solution", "Waste". It makes it easier, and you do not want to mix these bottles up. Since these aren't labeled that way, we'll continue without that. It wants me to "Please throw out the waste bottle. "It shows you a picture of which bottle to throw. So we're going to remove this, and we're going to essentially dispose of this in the proper method. This will be filled with waste solution. We're going to hit F10 to confirm. Again, we're following instructions, and now it wants you do take this bottle out and empty it, and put the old cleaning bottle that you just emptied back into the waste. Now you've got an empty waste container back into its position. I personally do not care if you have this cap facing the back or towards the front. A lot of people tell you there's a right and wrong way, and as far as I'm concerned is that you don't kink this tubing in here. It's not too much of a problem for the waste, but it definitely is a problem that happens with the cleaning solution.

Again, we're going to hit F10 to confirm, and now we are going to put in the cleaning solution. You do not want to mix these up. It's got a long tube to it. It's got the filter on it. It fits in, and again I don't care if you put it on like this, or if you put it on like this.

(Slide, 4:11)

A kinked tubing may stop the proper filling of the Cleaning Solution Reservoir. This bottle should always have solution in it.

Again, some people say there's a right and wrong way. The main thing I am interested in is that none of these tubings here pinch. You see, I don't like the way that's kind of wrapped around that. And it's not a big deal. I'm just saying, just for me, to put it in. I do care that these do not kink in any manner. A lot of times it will kink, you can see a little bend right there. And a lot of times, depending on how you put it in it'll kink back here. You do not want it to kink. So hit F10 to confirm.

Please enter the bottle, now you can see this isn't a full bottle. For demonstration purposes, I'm going to put 1500 milliliters in, and I'm going to put enter. And what's happening now, is the instrument is taking this cleaning solution and it's putting it into the cleaning reservoir, which is the small bottle. This bottle right here should always have solution in it, always.

(Slide, 5:25)

The cleaning bottle reservoir should always have some solution in it.

And if you can see this, that float in there is going to give you an error when you're out of cleaning solution. That's so that you can run the instrument even with this being low for so many tests. We're going to close the door. And that is it for replacing the cleaning reagent. Thank you very much for attending this session of BioMed Buddy on the changing of cleaning solution in the STA compact.
