HEPA Filtered Glovebox
    #17224293 - 11/15/12 01:19 PM (11 years, 4 months ago)

I don't know whether this is the correct category or not, (I'd assume so, as this falls under cultivation, I guess)

But I was wondering if anyone could take a look at my picture and tell me if there's anything wrong with my plan. It would be much appreciated.

This is a glovebocks/Flowhood hybrid. A glove box works on the principle of still air, thereby minimizing the chances of contamination. However, in my design, it is not still air, but rather, the air is moving from the right to the left. The air coming in is filtered with a class H13 HEPA filter.

So, could anyone take a look at the plans and let me know if this design will work or not?

Thanks.

Ditch all that crap and use a proper still-air box for best results.
Or a proper flow hood :shrug:

Thank for your input, but it offered me no help at all.
What, exactly is wrong with this setup?
Can you explain?

Telling me that having a class h17 HEPA filter air (Sort of like a miniature flow hood) in a glove box with a proper exhaust is complete crap i should ditch isn't exactly beneficial to what I'm doing here. Thanks.

You need laminar flow. If you're trying to recreate a flow hood, just build one.
Otherwise, a still air box works perfectly when you wet it down with soapy water and do the work quickly and efficiently.
The air filter, the uv light, the exhaust, the laminar flow or lack thereof- all this will be less helpful to you than just using a SAB :shrug:
Maybe someone else will chime in but that's generally the sentiment around these parts: still air box or properly constructed flowhood.
So to my eyes, that setup you have is worth less than my $10 box with 2 holes in the side. I do a lot of work in it and I have about a 98% success rate with agar and grain to grain and such.

That awkward moment when I spend about 5 $ on all that...

So I'll just get rid of the filter/fans on the side and the UV lamp, and have a basically just a box, and it should work well?

Yep. You will have great success :thumbup:

I would leave filters on both sides if you already have the material. Ambient currents through the box should lower the airborne particle count.

This defeats the whole purpose of the SAB.

why both sides? One intake has the filter, and the outtake just pushes out air....

FrankHorrigan is speaking absolute sense.  Listen to him mate. Your creation is likely to cause more contams as any spores etc that is already in the box will get blown all about because there would be airflow coming through the filters. It doesn't make any sense to do it that way. Get used to growing and to contams and you'll realise why.

If the air is copletely still, its impossible for contams to blow around.

This is why we use a bin with 2 arm holes in it and nothing else, so theres no way possible a contam could blow into your work, the air is absolutely still...

what they said. laminar flow is even across the filters face, so while it has airflow, there is no turbulence to stir shit up. only an even flow of sterile air.

But if you have a filter on both sides you don't need to run the fan the whole time.

I honestly think this would work fine. You could make it a little easier and make a flow hood with the hepa filter and make a box that comes from the hepa filter and then outward to an open long end of a box.




Like this.


That or you could just make a regular flow hood or regular still air box.

Like I said I'm pretty sure it would work and others are usually against trying something new since FTFT is pounded in everyones heads all the time. Up to you bud.

A good old still air box will work wonders, and is very easy/cheap to make.

To anyone reading this, I suggest acquiring the widest/deepest/highest clear tote one can find. Having ample room to work is essential to clean transfers.

Here is a Tek which demonstrates some impeccable g2g transfer work in a still air box: How to Do a G2G in a SAB

Sure, I use one myself. I have though about adding two hepa filters and allowing the ambient currents to clear the box. It would need to sit for a while before use to gain the benefit but I'm a patient guy. A fan would be useful though. I wouldn't recommend anyone do it, just building a basic box is good enough, but it seems like he already has the materials.

A fan and one filter would work, I would prefer two filters so I didn't have to work with the fan on. Once the air is cleared the fan could be turned off.
