Microfluidic Testing using an acrylic vacuum chamber
Our client performs a wide array of microfluidic testing in their laboratory. The requirements were 1. to install injection ports which are connected to a syringe pump outside of the chamber, 2. A gas port to pump gas such as carbon dioxide, helium, or argon into the specimen, 3. an electric feedthrough port in order to connect a heat plate and heat the sample inside the chamber during vacuum tests.

This was a custom chamber to which we added two feedthrough ports and an NEMA 5-15R power outlet (The same used in many US homes to power basic household appliances such as TV or a microwave)

The final design also included an aluminum base plate along with a heat insulator beneath to protect the bottom chamber wall from heat damage. Take a look at the light bulb being turned on as we pull a full vacuum on this chamber.

Did you know that we carry a many more products?

We make Robustly Designed and Quality Engineered Systems. What are you building? Take a look at the links below and discover some of the cool things we make.

Vacuum Oven Systems
Vacuum Ovens are vacuum chambers and ovens combined in one system. Vacuum ovens are necessary during processes which require the specimen to be subjected to a hypobaric and hyperthermal environment. Our Vacuum Oven Systems enable to you run a complete vacuum vs time and temperature vs time profile. We also carry portable vacuum oven systems and custom vacuum oven systems.
Rotary Vane Vacuum Pumps
Rotary Vane Vacuum Pumps are the most widely used vacuum pump in the industry. When it comes to performance at a reasonable price, rotary vane vacuum pumps are the way to go. Many Rotary Vane Pumps can achieve 2 to 5 milliTorr vacuum rating at a good volumetric flowrate (2 to 20 CFM) at a very reasonable price (hundreds to a few thousand dollars)
Our Work: Pressure and Vacuum Chamber used for Calibration of Weather Stations across the US
Have you ever wondered how the weather forecast works? You must admit; the weathermen (or weatherwoman) have become a whole lot more accurate over time. 10 years ago, the weather forecast was not as accurate as it is today. Part of the reason is that we have better forecasting technology as in more powerful computers who crunch numbers faster to out a most likely scenario. Another reason is that mathematics, physics, and science has progressed. The main reason however, is that we have better tools and equipment.

In this article we will discuss the vacuum levels of an acrylic vacuum chamber. This article also covers the leak rate or the leak tightness of the acrylic chamber. Additionally, we are going to recommend a rule of thumb used for vacuum pump selection based on the size of the vacuum chamber.
