Vacuum bags integrity checks

Hi

​I was asked a question today that I don't know the answer to - although I have given it some considerable thought!

I was asked if I knew where to buy a syringe attached to an airline to verify vacuum bags integrity checks - has anyone ever used this methodology? 

I've asked for further clarification on what she is exactly trying to achieve - am I missing something (I wonder)?

twelve liftimes ago I did this

We used something very similar to this hooked up to the air iine. Punched a hole, filled the unit with air, submerged watching for air bubbles on the seal

I'm assuming she means to put the seals under pressure (e.g. fill the unit with air til it resembles a pillow) 

I know exactly what you're wanting.  I had 2 at my last job.  Just don't know what they're called.  I'll look around and see if I can find a link to one.

I can't find one (yet)  but it looks basically like one of those syringe bulbs you get for cleaning ears, but has a longer nose end on it, with a inflator needle on the end.

I have not.   However, i have checked seals with (Not vac pack, but it is suppose to work):  Best Package Leak Detector & Seal Integrity Test Equipment (flexpakinc.com)

Sorry if this is no help.  

Yes, I have seen this in action, along with water submersion and putting soap on packaging to see if there are any bubbles.

The closest thing I've ever encountered is the needles you use to check the gases in MAP packaged products. We had to put the needle into an empty pack, and then put the contents into a machine to measure the gas mixture concentration. That was 10 years ago ... I can barely remember what the syringe looked like and it definitely wasn't attached to an airline.

Thanks all! 

I did testing similar to what Dee70 described, for MAP products.  You'd put a "sticky nickel" on the package, insert the needle and pull the barrel of the syringe.  But I don't remember if there was an attached airline or if the syringe content was injected into a machine.  Anyway, the machine used for the analysis was a Mocon.  The company is now called Ametek Mocon (or Mocon Ametek).  Maybe they have what you are looking for.

good luck!

Finally found something that's very similar to what we used.
Tandem EZ Squeeze Ball Pump - A25-041 | Anthem Sports (anthem-sports.com)

I'd put the vacuum bag under water, insert the 'needle' them pump the bulb.  If there were any seal issues, bubble would emerge.

Maybe ask the supplier of the vacuüm machine or of the bags? Chance they have it.
