Introduction

Vacuum chambers are devices for removing gases including air from an enclosed space. The air is sucked out of the enclosure using high performance vacuum pump and the chamber has to be sealed to a high degree to prevent ingress of air using silicon gaskets which do not degrade and are resistant to chemicals. The chambers are used in industrial as well as scientific applications and are capable of maintaining their vacuum seal for days at a time.

Here are the best 5 vacuum pumps and heaters on Amazon, starting with number 5…

#5 BACOENG 5 Gallon Tempered Glass Lid Stainless Steel Vacuum Chamber 

bacoeng-5-gallon-tempered-glass-lid-stainless-steel-vacuum-chamber

The BACOENG 5 Gallon Tempered Glass Lid Stainless Steel Vacuum Chamber is ideal for use in stabilizing wood and degassing silicones, resins, epoxies and essential oils. The chamber provides exceptional stability and will hold its pressure at a steady 30″hg (inches of mercury – approximately 14.5 psi) for as long as you need it.

The BACOENG is well designed and engineered to make it as easy as possible for the user. The chamber is made from quality stainless steel with a chromium layer to prevent any oxygen whatsoever getting in that could damage the chamber or your contents. Stainless steel is the perfect material due to its high resistance to temperature and corrosion and the BACOENG brand ensures that the chamber is built to the highest possible industry standards.

The lid is made from tempered glass which has much stronger resistance against cracking than the standard acrylic lids on other chambers. It also allows for visibility of the contents of the chamber at all times and allows work with more volatile compounds that could damage an acrylic lid. Other design features include the inlet valve being mounted on the side rather than the top, beneficial when releasing pressure and also when introducing material into the chamber, preventing direct spraying onto the contents and an observation window on the side. Th.e design of the chamber has been verified in labs and is proven to be reliable and safe

High quality accessories supplied with the BACOENG 5 Gallon Stainless Steel Vacuum Chamber:
Glass lid, 3-Way valve (with particle filter), oil filled pressure gauge, 5ft vacuum hose, reversable rubber gasket (can be flipped if damaged), non-stick silicone mat (food-grade)

Negative points to consider
As with any product there are always some slight downsides and for full disclosure here’s what we have found that you might want to consider:
– The inlet being on the side instead of the top slightly limits the depth of liquids that you can fill to
– The unit needs very minor assembly that can be done in 5 minutes using an adjustable wrench
– Reports that some of the minor hardware accessories are not of the same very high quality as the chamber itself, although this in no way detracts from the operation or reliability of the unit

The BACOENG has high ratings for Sturdiness, Value for money and Ease of use
This product has 94% positive customer feedback rating on Amazon and is the number one best-selling item in the Lab Vacuum category

Negative points to consider:
There are very few minor negatives but people have reported that the scale on the gauge can be difficult to read at certain pressures. This in no way detracts from the quality or accuracy of the actual gauge itself.
