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.

Stainless Steel Vacuum Chambers
Stainless Steel Vacuum Chambers are vacuum chambers made from stainless steel. The advantages of a Stainless Steel Vacuum Chamber are High Vacuum and a Wide Temperature Range of applications.
Roots Blower Vacuum Pumps
Roots Blower Vacuum Pumps are used when a large amount of Volumetric Airflow is Required. Root Vacuum Pumps cannot operate independently and must be used in conjunction with another roughing pump such as Rotary Vane Pump or Piston Pump. The advantages of a Roots Vacuum Pump is that the Pumping Speed can be increased by a factor of 5 up to a factor of 10; meaning that a 20 CFM Rotary Vane Vacuum Pump can now be boosted to pump 120 CFM!
Our Work: Vacuum Testing of Lithium Ion Batteries, Thin Film, Fuel Cells, Supercapacitors, and Nano materials
This vacuum chamber is a modification to our basic acrylic vacuum chamber 12 inch, removable lid model; except that our customer requested additional ports and electrical feed-through for testing of electrical equipment under vacuum. You know, I wish we would have asked them for more details on what they were doing with this chamber; their short and concise answer was that they were using our chamber to perform scientific work on the subjects of: lithium ion batteries, thin films, fuel cells, super-capacitors, and nano-materials testing in a vacuum environment.

Visual inspection is an attractive option because it does not require the purchase of any additional equipment. There are several arguments against Visual Inspection of heat seals; the argument against visual inspection is that visual inspection is subjective, unreliable, operator dependent, or not a valid method of inspection. However, if you have the correct training, procedures, and documentation in place, visual inspection can become a powerful tool in your quest for better packaging.
