Filter Patch Bags and PC'ing
    #6835689 - 04/26/07 06:17 AM (17 years, 8 months ago)

I acquired a couple filter patch bags and was wondering...if I impulse seal these bags and then pressure cook them, will they explode or will the filter patch be sufficient enough to release the pressure? I ask because I haven't yet built my flow hood (still need a filter) and was planning on inoculating the bags with a syringe through the ol' homemade RTV silicone injection port. I realize that you can purchase bags with the injection port already present, but those aren't the ones I have currently, and I'd like to use these. Any help is appreciated.

Search my username and 'tyvek sleeves' as the search criteria. I've posted a technique for using filter patch bags with a tyvek sleeve inserted into them. Don't seal until after pcing. They explode as the PC cools, when the large surface of the pc that is exposed to air cools faster than the interior of the bags which stays hot longer. That pressure has to go somewhere. My tyvek tek gives a way for the pressure to escape, and then when 0 psi is reached, the bag seals and the tyvek becomes a filter. It works.
