| My foaf was sick of the small capacity of his rubbermaid cheapo glovebox so he decided to build a new one, one thing lead to another and this is what turned out. Two 239 cfm fans with individual power cords (so he can use only one fan for delicate work like making spore prints), each with its own hepa (He thought one would cover both fans when he bought them, but he was wrong, wasnt big enough, so he used both) and the best off all, its all plexiglass so its lightweight and transparent. He used clear expoxy to hold the plexi together, sealed the inside with clear silicone to add some extra support, then to make it even sturdier he wrapped a few layers of duct tape around the top and bottom. Finally he placed the hinges on the lid, drilled and attached them, and placed a small bead of silicone around the rim of the box so the lid would contact something soft and seal a bit better. The only thing he has to do is attach some sort of latch so he can close the lid nice and snug.

| Hey Ozz,
I am putting the finishing touches on my PP box. I need a fan or possibly two. What kind of fans did you use? (brand name and model) How much did they cost? I will post a pic when i am finished. Thanks in advance for the info. Oh yeah where did you get your fans?

|Nice and big too.|

|My friend has a glovebox quite similar to this. He wonders what your method is for sterilizing before use and when you are adding materials? What my friend says he does is wipe down with bleach, then sprays with a few spritzes of lysol, run fan for 15 min. Then add materials wiped down with alcohol or bleach solution. A few more spritzes of lysol, close the lid and wait 15 min before starting work with alcohol soaked gloved hands. How bout yoU?|

|Baddasss ozz! Makes mine look like shit!! I need a posipressure box, But I have a very low contam rate using my rubermaid. Congrats on getting her finished,|

| Thanks everyone !!
Stevieray ..... http://www.electricmotorwarehouse.com/dayton_blower.htm the link that my friend purchased the fans from, 238 cfm axial fan, however, there are many blowers and other fans at that link that would work great, my design I found it easier to go with two fans instead of one heavier blower, hope this helps !!
Robinhood .... he usually just loads the glovebox with supplies spray heavily with lysol and turn on for about 15 minutes before working .... easy peasy japanesey
Yup, yup, my friend will be testing her out today hopefully !!

|that is 1 nice pro glovebox|
|Posted by: robinhood May 22 03, 10:44 AM GMT|
But this technique seems like a dilemma to me. Just as one should be worried about contams on jars, syringes, and other materials in the glovebox....doesn't one also worry about lysol in the same way? It seems that if you had lysol on the surface of your jars or on syringes, it could get into your substrate or your print and cause sickness and death. Isn't this ever a problem for anyone?

|Those fans blow hard enough to pull thru those Hepa's?|
|Posted by: OZZ May 22 03, 04:38 PM GMT|
| They sure do ....... both those arm holes are 5" diameter and have air rushing out of them to where theres no way in hell a lighter will stay lit in front of them. Also, around the lid you can feel a solid stream of air coming out of the cracks ..... also enough to blow out a flame.....much more pressure than my old glovebox and it did a fine job. What you cant see in the pics are the other two 5" diameter holes cut in the plexi that the fans are sucking through.

|BTW Robinhood, all syringes and tools are wrapped in tinfoil and PC'd to sterilize first. When taking prints the printing medium (foil, aluminum, ect) are also wrapped in foil and PC'd. All jars have foil caps on them, lysol is sprayed over these objects and the fans are turned on and the lysol is allowed to completely dry and then some (15 min), the lysol kills anything attached to the outer foil layer on tools, syringes, ect. and the foil caps on jars as well as anything on the jars themselves. Foil caps and wrapping are removed and the work is started.|

That sounds like the ideal way to go. Thanks for making that clear!
|Posted by: Nanook May 23 03, 01:07 AM GMT|
|That is the correct proceedure... I wipe the box with bleach solution and let it dry. Then I load the foil wrapped and pc sterilized jars, dishes, tools, etc into the box and spray everything with lysol. Turn on the fans and let run till dry (20 mins or so) then reach in with sterile gloves, unwrap, and go to work|

|Lookin good so far, keep up the good work. I have yet to understand the concept of a pp box but when the time comes, I will sit down and learn the mechanics behind it.|
|Posted by: OZZ May 23 03, 08:55 AM GMT|
|Well Sinoptik ... basically the concept behind a PP glovebox is that the fans are pushing so much filtered air into the box that it rushes out of every opening in the box itself, therefore no unfiltered, outside air (contaminants) can get in. You spray the inside with lysol, thereby sterilizing the interior of the glovebox and its contents, you then turn on the fans which circulate the lysol killing all contaminants inside ... from that point on filtered air is rushing out of the arm holes and any cracks that may be in the glovebox at such a rate that it is impossible for contaminants floating around in outside air to float into the glovebox and get near your work. Make sense ??|
