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.

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: Custom Vacuum Chamber with Blank Plate
You are looking at our standard Acrylic Vacuum Chamber, Hinged Door with Clamps. There is only one difference; this vacuum chamber has a blank acrylic plate that is connected to and aluminum plate which in turn is anchored to the side wall of the acrylic vacuum chamber. This blank plate is there to enable our client to add vacuum feedthroughs to the side wall in the future

An Acrylic Vacuum Chamber can be used to simulate elevation very reliably to altitudes up to 60.9 km or 200,000 feet. This provides several advantages over other testing methods as acrylic is transparent and enables full view of interior during testing. In this article, we will give you a through guide on what can be done to eliminate the risk of packaging damage during shipments at high altitudes.
