I kind of feel like if one reads the initial post, and really digests what it says, one is not likely to float the idea of creating a cheap Franken-hood.

Seems like an FFU is as close to DIY as you can get. It’s not super simple but can definitely be done cheaper than a commercially built flow hood.

Diy hoods are easy to make so lomg as you choose the correct equipment, both of my hoods are DIY:

I bought a flatpak hood from LabRatz because I don't have a table saw. If I'd done more research I probably would've went with an FFU, not much pricier in the end, and more standardized/documented parts.

My filters were built to order, they're designed specifically for laminar flow applications and manufactured specifically with mush cult in mind.

The blowers are matched to the filters, they're as reliable as any ffu. I'm not familiar with labratz so I cannot comment.

So a glovebox is not okay but SAB is?

The level of delusion :tongue:

So long as the box is hermitically sealed (as well as the glove insertions) this makes no sense.

There should be no "vortex" created because there should be no fluid contact between the internal and external air.

Any movement of your hands in a SAB or GB is enough to create a movement large enough to unsettle the sedimentation of the particulates at the bottom. Even micro "stutters" of your hands. Seeing as the particles are light enough to float in the air in the first place. (and every part of your body is giving off a thermal/skin "cloud" so to speak.) 

And as friendly reminder, bacteria can control their fluid buoyancy. They learned to do that from hundreds of millions of years evolution LMAO!

Meaning they can make themselves lighter than air in search of nutrition and ruin your entire SAB idea.

Anyway


Regarding MERV and HEPA, MERV can catch some of the larger containments (which would give you about 10-20% less contam), but definitely not any of the actual bacteria that can float by themselves. Or that latch onto even smaller particles.

I want you guys to think of it likes this. Not all birds can fly, but a lot do. Most aren't flying all the time. The smaller you are the easier it is to fly and keep flying. So one of the smallest things in existence... As well bacteria can "walk" its called flagella. Human sperm cells borrowed that little micro invention. 

Just to conclude though a DIY hepa filter glued to a fan is just fine. Sure they won't achieve 80-99% filtration. But any filtration is better than none.

Laminar flow is important to keep contaminated air away from the clean flow, but again you aren't in a operating room with a patient on the table. It's a damn mushroom.

Nope I hate discord. (That was compulsive, no flaming here. Just a pun.)

Anyway I do agree with you regarding Laminar flow hoods.

It's usually cheaper to just buy them, because the filters and fans are pretty expensive. And so is the plywood and the time you need to make them yourself (if you're skilled enough at carpentry)

But the options are either 2000$ custom or lab version or podunk poop for 300-100$.

I saw some guy slap a merv filter on a plastic bin and charge 210$ for it. :sad:

There is an internal atmosphere, turbulence is created by disturbing the internal atmosphere within a hermetically sealed glove box. Glove boxes are intended for use with materials that cannot come into contact with the external environment for any number of reasons; still air is not a consideration for glove box' because they're not intended for sterile culture work in a microbiology lab.

Perhaps if the glove box was a true vacuum, maybe then you could make some claim regarding turbulence, until then:lol:

Cmon man, at least think before posting.

Also, what happened to friendly conversations? Why do these posts always come flavored with a hint of hostility?

Nothing, It's just a hit or miss with the suppliers. You could either get a good one or a bad one.

I don't like to gamble with half a thousand dollars.

This is a great example of what goes on here. "You're a idiot think before you post" to "Why are you so rude and hostile"

I'm honestly not even going to argue with you, because everything you say is like listening to a AI. Everything is coming out garbled and contradictory.


But let me break it down EVEN MORE. I will make this incredibly simple.

-SAB bad because they have bad stuff in air still. Hands go in mix bad stuff with good stuff. Ruin point of SAB. (Doing something and failing then making up a reason that conflicts with your original intent is cognitive dissonance.)

-Glovebox good because it no need you put the bad stuff in good stuff. Glovebox only glovebox if glovebox is sealed from bad stuff.

-Just like, tree only tree if it made of wood and make leaves.

-Your Argument is "well if a tree isnt a tree it cant make leaves" -> "If a glovebox isnt a glovebox it won't work like a glovebox"

Question.

How do you seal glove box from bad stuff when you load in your jars and plates and tools?
