Dye Ingress Test inside a Transparent Test Chamber

Dye ingress is most commonly used as a container closing integrity test in order to quality test sterile products. This test is mostly done in the Pharmaceutical Industry or Medical Packaging Industry as means to test for product defects in rigid container. It is based on the concepts set forth by the ASTM 4991 and used as a seal integrity test. In addition to rigid containers, blister packs and heat-sealed trays, can also be tester in accordance to this method.

Our Acrylic Vacuum Chamber is the perfect candidate for the ASTM 4991 Test because the method calls for a “transparent test chamber”.

Fortunately, you have many to choose from since we have a large selection of transparent test chambers. Each of our vacuum chambers comes as a standard with a dial vacuum gauge and two vacuum valves (venting valve and vacuum valve)

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.
Digital Vacuum Gauge Instruments
A Digital Vacuum Gauge is an instrument which precisely measures a vacuum level inside a vacuum chamber. Unlike a rough dial vacuum gauge, which shows only where the vacuum chamber is roughly with an error of up to 3% (a high as 1 inHg) a digital vacuum gauge will show vacuum levels up to 3 significant figure in Torr and millitorr – this makes the digital vacuum gauge ten thousand times more accurate than the dial vacuum gauge.
Our Work: Research, Development, and Testing of Weather Balloons inside a Clear Vacuum Chamber
A wonderful company (more like one of the best companies in the world) which is currently involved with the research, development, and testing of high-altitude weather balloons, had a need for a vacuum chamber capable of achieving about 100 micro Torr (Micron) of ultimate Pressure for their testing environment. Fortunately, acrylic vacuum chambers are the perfect choice when it comes to Low, Rough, and Medium Vacuum.
