What is a KI test?

If you have a microbiological safety cabinet, you may have heard of a KI test. Having your safety cabinet tested when necessary is integral in ensuring that its in good working order and safe to use, but is a KI test what you need? Here, we look at what a KI test is and how it can determine if your safety cabinet is functioning correctly.

What is a KI test?

A KI test checks the performance of safety cabinets to ensure that they’re working safely and efficiently. In the KI test, a spinning disc produces a fine mist of potassium iodide droplets within the cabinet and centripetal collectors outside of the cabinet sample the air as the droplets are dispersed.

The potassium iodide droplets that are collected are deposited onto filter membranes which are placed into a solution of palladium chloride at the end of the test. Any potassium iodide will then be identified by brown dots, and the safety of the cabinet is determined by how many dots appear.

What are the benefits of a KI test?

There are a number of benefits to be gained from using a KI test. Firstly, it offers an efficient way to test any open-fronted Class I, II, or III microbiological safety cabinet, and can be used for cross-contamination applications too.

In addition to this, the results from a KI test can be seen very quickly, so you don’t have to wait around for results before finding out if anything needs fixing, plus this test is industry approved so you can be confident that it will help to keep your workforce safe.
