BACOENG 2 Gallon Acrylic Vacuum Chamber, Degassing Chamber Kit for Resin, Silicone and Epoxies

My camera stopped working after some water got into my phone. I already had a vacuum pump for doing car A/C work and tried to DIY a small vacuum chamber for my phone but it just wasn't working. This showed up 14 hours after I ordered it, I ran the vacuum pump for 25 minutes and all the water was removed from my phone. Now my camera is working perfectly once again! This thing is built really well for the price, nice thick acrylic, easy to use and hooks up with a 1/4" manifold set (or the included hose is a standard 1/4" size too). I'm thrilled that I don't need to buy a new phone thanks to this item.

Great size for cell phone, camera, etc drying. Used with my AC vacuum pump and works great.

This worked but at first it didn’t. I had to press down on the top when first starting to get a seal and then it’s good to go. I have to do this everytime. Not a big deal. BUT, Omg, the smell. It was overpowering. I’m not sure if it is the glue they used to adhere the acrylic pieces together as it is a rectangle shape or what, but it was truly nauseating and if I could have left it outside to air our for a few days, I would have. Unfortunately, I did not have that option. I am not exaggerating, it made me feel lightheaded and dizzy and lasted for a few days. So, something to keep in mind. Otherwise though, I’ve successfully de-gassed silicone twice now and I do appreciate being able to watch it through the clear acrylic from all sides.

This is so cool but it really should come with a vacuum pump! Doing all kinds of science experiments!

It holds a vacuum longer than it says it will. I've very pleased so far.

Good concept but what I received would not produce a seal and thus incapable of any vacuum. I verified that everything up to the inlet port from the tank was proper and function, the lid just sits on the base not that there is interface, so perhaps the rubbery wrap around the lid could not seal against the chamber's top surface.

It doesn’t evacuate the chamber like I needed It to, which is unfortunate. What I ended up doing is taking apart the gauge from everything else which was not easy and making the hose connect direct to the lid and then placed the gauge inside the chamber itself. I was quite frustrated to start because the gauge would read -25 inHg but my sensor (barometer) never changed and only showed ambient pressure. Once I made the change it was then pulling a vacuum as expected but because I need USB-C Power to the device, I still have an issue, so I ordered some silicon sheets to create a secondary gasket that I will be able to feed the usb cable through and keep a seal. This should allow me to test pressure up to about 40,000’ or so. It would be nice to see a version of this with a built-in usb-c Feedthrough and maybe another feedthrough for wiring. It would also be nice if I didn’t have to take the guage off and put it in the chamber and reconfigure everything to pull it down properly. But hey, it will work with some minor changes and I’m probably not using it for its intended purpose. Also, the pump seems to use oil really fast

It functions exactly as expected, compared to trying to diy build a tank yourself this seems like a no brainer. It seems to seal perfectly, so far no complaints about the build quality, its easier to just buy this than to make your own so it’s worth the cost, and it’s very straightforward to use.
