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 Bubble Emission ASTM 3078 Leak Testing Systems
Bubble Emission (ASTM 3078) Leak Testing Systems are instruments that are used during the Quality Control process discover and locate leaks or seal integrity failures. Leaks are detected by submerging the specimen into a tank of water, applying a vacuum, and inspecting the submersed specimen for bubble emission. Our Bubble Leak Testing Systems are designed and built to conform to the ASTM D3078 protocol standard.
Rotary Vacuum Feedthroughs
Rotary Vacuum Feedthroughs are devices that will enable you to physically rotate a specimen inside the vacuum chamber while vacuum present without decreasing the vacuum.
Our Work: Vacuum Storage of Pharmaceutical Products and Medical Supplies
A pharmaceutical manufacturer contacted us to build them a large vacuum storage system for their pharmaceutical products. They were looking for as much footprint as possible which is why they got a two-chamber system from us. They needed a total of 6 shelves per chamber including trays. Finally, they were looking to have both chambers to be placed on a table frame assembly with lockable swivel casters. What you are seeing is a two chamber system, each chamber is our 20 inch cube acrylic vacuum chamber, front load hinged door. Each chamber can be accesses independently while the other is under vacuum. The trays can be easily loaded and unloaded. This whole system can also be moved to anywhere in their facility.
