In the bubble point test pore size rating is determined by measuring the lowest air pressure needed to overcome the surface tension between the wetting liquid and the membrane pores in a fully wetted membrane.
By immersing the filter into solution and slowly raising the gas pressure on one side the pore size of the filter can be determined based on the pressure point that bubbles appear in the solution.
The portable vessels are available in 5 10 and 20 liter and 1 gallon capacities.
A bubble point test is a test designed to determine the pressure at which a continuous stream of bubbles is initially seem downstream of a wetted filter under gas pressure.
Bubble point test apparatus.
Our bubble point tester will accomplish your goal of testing small volume devices such as syringe filters.
This pressure level known as the bubble point is signaled by the first appearance of a steady stream of bubbles observed from a special disc.
Why p erform a b ubble p oint t est.
A wide variety of bubble point test equipment options are available to you such as electronic.
Bubble point is based on the fact that liquid is held in the pores of the filter by surface tension and capillary forces.
Bubble point test is a non contaminating non destructive filter integrity test that is commonly used during both the product design and quality control process.
The bubble point test exploits the fact that liquid is held in the pores of a filter by surface tension and capillary forces.
Dispensing pressure vessels hold liquid for filtration through millipore pressure operated filter holders if connected to an external pressure source.
Vessels meet asme um code requirements.
The most widely used non destructive filter integrity test is the bubble point test.
