3 Key Attributes to Look for Before Purchasing a Bubble Point Tester

 


Bubble point tester is an easy technique for estimating the largest pore size in a membrane by calculating the pressure needed to blow air through a dampened membrane. The testing shows the force's equivalence required to transfer one fluid to another through a pore diameter.

Why use Bubble Point Tester?

The Bubble Point Tester gives a quick and precise estimation of a material's biggest through-pore (bubble point). It is easy to understand and completely automated. It produces reproducible and exact outcomes.

The bubble point technique for integrity testing is efficient and powerful in its application. It relies upon the gauge pore sizes. The bubble point test depends on the capillary rise that yields relative estimations of the membrane's biggest pore sizes.

Generally, the bubble point value is indicative of the filter's largest pores. Given that the predominant system of pore evacuation by the filter relies upon size separation, the concern in leading a disinfecting filtration is that they should not have pores big enough to enable the microorganism to escape capture.

The bubble point test relates to layer pore size identifying the biggest pore by constraining the fluid from such pores and making a bulk flow. It is moderately simple to perform on small to medium scale channels, for instance, 47mm plate channels (13.5cm2) up to30" filter cartridges (1.8m2).

The test done on small scale gadgets cannot be tested through the diffusive airflow estimation or the pressure hold test. The test duration can be brief because of short adjustment periods and faster pressure rises.

What to look for while Purchasing the Bubble Point Tester:

Filtration system:

Determining the right filtration system is one of the critical issues that should be considered, given the product tested type. Numerous reasons, such as particle load, instabilities in pressure and temperature, and cleaning steps (which have high temperatures or changes in pH), can cause wear and tear to the filter elements. Continued performance of the filter becomes one of the critical parameters of the process controlled. Using a filter in the process can be led to various damage such as irreversible blockage of the filter membrane and cracks or alteration to the membrane or pore structure. Although blockage shows during the process, cracks or changes in pore structure are not spotted that easily.

PROCESS INTEGRATION

The data transfers in two ways: electronic data storing or hard copies with no data stored.

Using electronic data storage, factors that need to be well-thought-out is that the bubble point tester is compatible with all other equipment like PLCs, computers, SCADA systems. The equipment should be able to transfer data both manually as well as automatically. And the storage needed.

Qualifications:

Qualification of a bubble point tester is a vital part of the process. Contractors show clients with the device and with qualification etiquettes enhanced for an effective and protected method based on the contractor's knowledge. Three types of qualification need to report, which are

Installation qualification (IQ) that provides written verification that the tester fulfills the requirements of the approved design and condition.

Operational qualification is to verify the documents with more complicated tests confirming that the test is within specification.

Performance quality verifies that the tester can perform efficiently and reproducibly based on standard operating procedures.

To summarize:

It is vital to look for these traits when buying a bubble point tester because of the failure of any of them can delay testing. That may then delay production and product release. For testing with fields other than water and alcohol-water solution, a specific test is needed.

Mercury Porosimetry Testing Vs. Compression Porometer Testing: How Do the Two Differ?

Image
  In Mercury Porosimetry testing , the pressure is actually applied to force mercury into tinier and tinier pores. Hence, the pore size distribution can be projected by measuring the applied pressure and the intrusion volume in the test using Mercury Porosimeter. But what exactly is Mercury porosimeter? Precisely, it is an automated and versatile engineering instrument used to control various properties. It basically allows mercury porosimetry testing under higher or lower temperatures to put on concrete operational conditions. On the flip side, The Automated Compression Porometer is uniquely designed to portray the pore structure of any material under compression. The instrument also permits tests to be carried out under proper virtual service conditions. Engineering industries globally, varying from the non-woven to the filtration and battery, use the PMI Compression Porometer for quality control and R&D. Samples that are often tested in this marvel machine include membranes ...
