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.

Acrylic Vacuum Chambers
Acrylic Vacuum Chambers are, as the name implies, vacuum chambers made from the Acrylic Polymer. There are several advantages to acrylic vacuum chambers the three main ones being 1. Fully Transparent, 2. Cost Effective, and 3. Versatile and Highly Customizable.
Altitude Simulation Controller Instruments
An Altitude simulation Controller is type of vacuum controller that simulates a certain altitude because altitude can be derived from vacuum levels. An altitude simulation controller will enable you to hold your vacuum level at a certain altitude equivalent of testing, run an altitude vs time profile, or rate of change of altitude vs. time. Further options include a vacuum pump relay that will control when the vacuum pump turns on and a vacuum valve.
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.
