Vacuum Soil Sampling and Extraction for Geological Research
What you see here are two identical vacuum chambers with a spring supported lid which are used in vacuum soil testing and extraction methods. Our client asked us to provide them with two vacuum chambers capable of reaching vacuums below 1 Torr absolute.

Since the test specimen preparation time is much shorter than the vacuum sampling time, it makes much more sense from an efficiency standpoint to use two vacuum chambers. In addition, the test is done in two stages using one chamber as a staging chamber and the other one as the sampling and extraction chamber.

A spring support lid chamber is the ideal choice for such applications. The lid stays open as the samples are loaded into the chamber. Then, after the chamber is loaded with the test specimen, the lid is closed and clamped and vacuum can be applied to the chamber. This chamber also comes as a standard with a vacuum valve, a venting valve, and vacuum gauge, a handle, two clamps, and two spring to support the lid.

Some of our Popular Items

Our clients prefer to work with us because we are Experts in Vacuum Science and Technology. Check out some of our other items we carry that you can combine/integrate with your systems or projects.

Vacuum Chamber and Pump Systems
Our Vacuum Chamber and pump systems are fully setup and ready to go. What you get is a vacuum chamber, a vacuum pump, and connection hardware. We carry acrylic or metallic vacuum chambers and a whole range of vacuum pumps from Rotary Vane, Piston, or Venturi. What type of vacuum chamber and pump system you want depends on your project requirement, budget, and other specifications.
BNC Vacuum Feedthroughs
Coaxial Vacuum Feedthroughs are vacuum rated BNC connectors that enable you to run BNC from outside of vacuum chamber towards inside of the vacuum chamber without disturbing the vacuum. Triaxial Vacuum Feedthroughs, just like coax vacuum feedthroughs, will enable you to run Triax Connections from outside towards the inside of the vacuum chamber without disturbing the vacuum levels inside the vacuum chamber.
Our Work: High Altitude Vacuum Testing of Electrical Connectors and Components
This was an interesting project where one of our customers needed to test wires up to 44 inches long within a high altitude simulation environment. In addition to testing wires, several other electric connectors required altitude testing as well. The altitude requirements were 100,000 feet (30.510 km) which corresponds to 8.36 Torr - a piece of cake when it comes to the vacuum requirements of our chambers.
Related Articles: Force Decay Leak Testing
Force Decay Leak Testing is a very popular quantitative leak testing method used to quality test package and product integrity due to its ability to detect small leaks which cannot be seen through visual inspection. In this method, the test specimen is internally inflated by either internal pressurization or vacuum force. The inflated test specimen will, in turn, apply a force on a pressure transducer. Finally, the change in force applied by the inflated specimen over a specified time is observed.
