1.5 Gallon Tempered Glass Lid Stainless Steel Vacuum Chamber Perfect for Stabilizing Wood, Degassing Silicones, Epoxies and Essential Oils

I'm new to vacuum degassing. I did some research on products and settled on the Bacoeng setup. I originally was going to get a smaller chamber but decided to spend a bit extra on the 1.5 gallon size. I'm glad I did. It fits a decent sized container or several small ones for degassing and having the gauge on the side leaves the glass top clear for viewing the process. It's fun to put marshmallows in and let my 7yo learn some things. It holds the vacuum really well. I pulled it to -29.5 and left it for 24 hours and held without issue. The glass lid is heavy and it seals quickly and the chamber walls/floor are thick and sturdy. The gauge and valves that come with it are sturdy and work very well with the chamber and the silicon mat is thick and appears very well made. It's packed really well and arrived quickly with no damage. If I had to nitpick on something, it would be the rubber washer used for the gauge on the inside of the chamber. You've got to tighten the inner nut quite a bit to squish the washer enough to ensure it seals properly. See picture. Having a thicker washer, or maybe one that's a bit more solid would help it seal a bit easier. Otherwise 5 stars all around.

Nice size for epoxy debubbling, with a decent pump it works pretty quickly. Lid seal seems to be sturdy and haven't had any issues so far.

Love the size of the tank, I needed a larger diameter tank - not a taller one. Most 5 Gallon tanks are taller, this one is wider. Tank quality is solid. Lid quality is solid. I don't like the valve/gage quality. My smaller tank of half-the-price had better valves and worked right off the bat. This one even with light tightening, firm tightening, and tight-tightening, has yet to keep the vac solid. My much cheaper tank will hold -30hg for 4 days without touching it. This one I've yet to have it not loose 2hg within 3 hours. Tempted to just contact the cheaper-pot company and ask them for a gage set instead.

I’ll be blunt. I have three vacuum chambers. All are Bac Eng because the quality is second to none. I have a small one for epoxy, a mid sized acrylic one for short term vacuum and special projects that require visibility. And of course this 5 gallon beast. I use it for storing things that require long term vacuum storage. This chamber was purchased almost a month ago and I pulled a vacuum on it all the way down to -28.5 inHg. I just checked it and it’s reading -28 inHg after all this time. That’s absolutely astounding for a vacuum chamber to hold for that long and barely lose any vacuum. The very thick tempered glass lid is a great innovation and is the reason for the incredibly effective consistent vacuum. Easily one of the best purchases I’ve made in a long time. Highly recommended.

Works well if you press down hard on the glass to seal the lid. Helps that the glass is about 3/4 inch. Pot is heavy aluminum. I also lubed the pot lip with vaseline before starting. It held -23 inhg overnight. Nice unit.

I have seen a good number of these "emulated" at DIY websites, normally with acrylic tops. I had expected to get a pot much like what I had in the kitchen and nice piece of glass. I was flat out blown away by the quality of the this Vacuum chamber! The pot itself is very heavy stainless steel, much thicker than what I expected. A true pressure vessel! The glass top? 3/4 of an inch of tempered glass! Incredibly thick and hard to believe at this price point. Set up was a breeze, screw on the gauges and in moments I had -26 inHG. It comes with a top quality hose with 1/4" flare fittings, fit my current setup nicely. So much better than the dinky desiccator I was using, I am very pleased with every aspect of this unit! I would give a sixth star if I could.

I have no complaints. The quality is good. I would buy this again.

Just perfect. Worked great and holds really good.

Devo dire che è realizzata molto bene, buona qualità dei materiali, vetro molto spesso, guarnizione di buona qualità, perfetto il funzionamento (la utilizzo per degasare resine poliestere bicomponente) insieme ad una pompa per vuoto bistadio. Ritengo molto comodo il fatto che manometro e tubazioni non sono fissate al coperchio ma alla parete del contenitore, questo permette una più semplice apertura.

Tres bonne qualité .

Erstklassige Verarbeitung, nach 24 Stunden Test ist das erzeugte Vakuum noch voll erhalten. Test bei leerem und sauberem Gefäß, klasse...

Great chamber

I go this to help with a large epoxy project initially. I decided to go for the tempered glass lid as I read reviews about the plastic one being damaged by some chemicals. The lid is solid and quite heavy. The chamber seems well made and I'm glad a got the 12L versions as it seems like the sweet spot for having enough room and not being to large to store. The valve assemble all worked fine for me and was simple to use. Seemed to hold a vacuum well right out of the box but sometimes the lid needs to be wiggled or pushed down to get that initial seal. Made a big different with the epoxy and removed a lot of trapped air. Came with spares and the vacuum hose also seems well made so hoping that this all lasts a long time.
