Hello,

I´m with difficulty to make total vaccum.

I´ve tried 3 times, with 3 diferent moulds, and never achieved total vaccum, there´s always a leak.

I´ve checked the gum tape several times, and nothing.

So i´ve tried with a Trough Bag connector at the vaccum line, and  the feed line without connector, only the pvc hose with gum tape.

The result was the same, so i decided to make some tests.

First test:

With the Trough bag connector closed, i´ve switched on the pump, and when the gauge indicator got to the end, i´ve closed the pump valve, and then switched off. The gauge indicator moved, so there is a leak somewhere between the Trough bag connector and the pump.

There´s a few fotos taken with 2 minutes between them:

Second test:

With the Trough bag connector closed, i´ve switched on the pump, and when the gauge indicator got to the end, i´ve clamped the vac hose between the Trough bag connector and the catch pot, closed the pump valve, and then switched off. The gauge indicator moved not so fast as the first test, but moved, so there still´s  a leak.

There´s a few fotos taken with 2 minutes between them:

I don´t know what´s happening, if someone know, please give me a help.

Another issue: When i connect the vac hose to the silicone connector, i´ve got to cut it to be more thin, otherwise the tube won´t fit in the hole with the bag thickness.

Thanks,

Pedro

Your welcome

It really makes you nuts with all the time it takes to set up an infusion and then you have a leak so small you will never find it.

Just an update from the last time I posted . Following the advice I gave above I have now had 8 perfectly sealed bags in a row.

Even with the stretchelon vacuum bags. You will find that you hardly have to spend any time going over the tacky tape seal as well.
