Create a small vacuum chamber for less than $30

Last Updated on

Vacuum applications in the industry and in research laboratories are numerous and varied.

A vacuum pump is a device used to extract gases and unwanted substances in a process, product or system.

The vacuum pumps work only in a limited range of pressures, therefore the evacuation of the vacuum systems is carried out in several stages, using for each of them a different kind of pump.

The operation of a vacuum pump is characterized by its pumping speed and the amount of gas evacuated per unit of time. Every vacuum pump has a minimum inlet pressure, which is the lowest pressure that can be obtained, and also an upper limit to the outlet or pre-pressure. If the previous pressure increases above this value, the pumping stops.

A vacuum chamber sells for about $400 to $500 on Amazon, but I’ll teach you how to make it yourself for less than $30! You can use this vacuum chamber to perform some interesting scientific experiments to see if items are in a vacuum.

What will happen? Because the material of the vacuum chamber is glass, you can observe the complete change. You only need to use a few basic materials and spend less than one afternoon to create a best vacuum chamber of your choice. When you use a refrigerant compressor, use straps to wrap the socks or fabrics in the pipeline to prevent the oil vapor from flowing out. The compressor is a small amount of oil circulating in the system, if you use this method, It will produce a small amount of oil vapor.”

Before knowing how to create let’s know use and advantage of vacuum pumps

Uses and applications of vacuum pumps

Vacuum pumps can be used in many industries, for example:

  • Food industry
  • Chemical industry
  • Pharmaceutical industry
  • Plastics industry
  • Beverage industry

Advantages of vacuum pumps

Vacuum pumps have great advantages, such as:

High efficiency

Vacuum pumps provide high efficiency due to their double chamber, so the displacement is maintained at very high vacuums and it is possible to evacuate large amounts of air or gas in a short time.

Long life

Due to its simplicity of design and construction there is no contact between its internal parts.

Simple operation

They are free of vibration, shock and work silently.

Construction option

They can be built in a wide variety of materials resistant to gases or special vapors.

 You will need these materials and tools:

  1. As a base block, it is thicker than 3/4” without cracks. The surface is smooth and the flatter the better.
  2. Take 2 beverage bottles (including caps) from the recycling bin as a drain valve.
  3. Vacuum gauge, you need to buy it, it’s cheap.
  4. Vinyl pipes are relatively cheap. There are two sizes on the compressor. Inner diameter 3/16” (4.7mm) or 1/4” (6.3mm).
  5. Refrigerant compressors. You can go to the community on a large garbage day to see if anyone wants to lose the freezer, dehumidifier, air conditioner, or small refrigerator. Although your A compressor may not be in very good condition, it is usually available (you may need to ask the nearest air conditioner to separate the refrigerator, dehumidifier or air-conditioner compressor). Wear goggles!
  6. Glass cover. You can use mason jars, pickled pickle jars, large glass jars, vases, or any cylindrical glass container with a flat top.
  7. Silicone insulation mats. A lot of attention, you may be able to see in the $10 store.
  8. If you want to experiment with electricity, you can use 14/2 wires.
