Just used Press'N Seal to seal the arm holes in my SAB
    #23845656 - 11/18/16 03:42 PM (7 years, 2 months ago)

The arm holes are too large for PVC plumbing fixtures and caps, and they have closed cell pipe insulation around them as well. ( to cover any sharp edges and to reduce the diameter of the holes for less air inflow)

I'm using the box for a pseudo-incubation chamber for some petries, and wanted to seal up the armholes. I happened to have some Press'N Seal laying out, so I pulled some off the roll, and was pleasantly surprised to find it adhered to both the plastic box and the pipe insulation. 

It was far easier than my original plan to tape some plastic sheeting over the holes.
I may cut a big slit in the middle of the PNS coverings to minimize air disturbance/anything that could push more outside air into the SAB.
When you lower the sheet of PNS to cover the arm hole, it seems to me like it's probably pushing a small amount of air into the SAB.
Simple
Cheap
Effective

Hope it might help someone else.

(searched for press'n seal, and didn't see any mention of this)

Someone on this site uses magnetic sheets to cover the holes.  This is the best thing I've seen  and imo is better than the pvc.  I use velcro strips and plastic sheets but I'm going to switch to the magnetic sheets whenever I find them.

btw when you are actually using your sab you don't want small holes (in your case a slit).  Small holes or openings cause something we call "the piston effect"

I use a 66qt tub lid leaned against the holes.

I saw the magnetic sheet idea too, and that somewhat inspired this idea.

The 'piston effect' is what I feared I was getting when I lowered the sheet of pressn seal. I wonder if that isn't more a function of speed rather than total misplacement. The large sheet coming down could trap/push more air than an arm going in...
Still a good point though.

I've never even bothered with covering my armholes. Its not something thats going to make or break your operation. The real beauty of the sab is the wet walls. Even if air gets moved around, it gets trapped in the water.

The only real time I seal it up is when printing, and letting things cool down. Even the cooling thing tho you don't need to cover it up.

It's not being used as a SAB with the Press'N Seal...
It's being used as an incubation chamber in a backroom that's less than ideal for this. That's why the arm holes are covered.

There's nothing wrong with covering your arm holes, and if there is I'd love to hear a reason that makes sense.  I can think of more reasons to cover the holes than not to.  Unless, I mean you are completely going out of your way to do it.

Some times there is a reason to cover the holes, like printing, it doesn't defeat the purpose

More air movement than if you had not. I think it's more detrimental than effective it you're trying to use it as a SAB

I use my Sab about three days out of the week.  I tend to leave my Petris in the Sab when I'm not doing work in my Sab.  So I cover up the holes.  Still don't get why this is a bad idea? 
Obviously if the Sab was empty I wouldn't bother.

:whathesaid: I think it's better to use it as a regular old SAB than a GB, because you're wafting a lot more air around with any movement you make when you've sealed up the box and trapped air inside of it. Maybe if you're some kind of sterility master who can ensure that the GB and everything inside it is sterile, then a GB becomes more viable. But I don't know how one would do that consistently and effectively.
