From the Lab to the Exam Room: Lite Tech QA Testing Process

Lite Tech is your single source for radiation shielding materials, from aprons and vests to protective eyewear and storage solutions.

But how can you be sure that Lite Tech’s products are the safest and most effective on the market?

Consider this break down of our quality assurance process to put your mind and wallet at ease.

First, our products are separated based on core material of which we offer two categories:

Xenolite B-3: The Xenolite-patented “light lead” technology combines four attenuating elements – antimony, lead, tungsten and barium, which are embedded in a thermoplastic elastomer. Lead counterparts to this material are 21% heavier.
Xenolite Lead Free Materials: Xenolite NL is our lightest lead-free core material option. It is comprised of two x-ray attenuating metals, antimony and tungsten, which are also embedded in a thermoplastic elastomer. The amount of each metal is optimized to ensure a balance that minimizes weight and maximizes attenuation. Lead equivalents are 32% heavier.
o We also have two other lead-free product lines: Xenolite Strata and Xenolite TB. Both containing antimony and bismuth metals for x-ray attenuation.

Once the metal powders used in the Xenolite sheet arrive at the manufacturing site, the hard work begins.

The Sieve Test

A sieve analysis, or gradation test, is a procedure performed on an incoming lot of metal powder to determine the relative proportions of different particle sizes in the lot, prior to its use in the manufacture of Xenolite sheet. After verifying that the lot meets Lite Tech’s internal specs for various particle size fractions, it is released to Production. In the event a lot of metal powder does not meet Lite Tech’s specs, it is quarantined and appropriate action taken. Particle size and its distribution type are paramount to the long term performance of the resulting Xenolite sheet, particularly its resistance to wear and cracking mechanisms – and ultimately, to how safe your medical staff are during procedures such as fluoroscopy.

Other QA Measures

At Lite Tech, our employees care about the safety of your medical staff and the longevity of your Xenolite products. Therefore, before being used in an x-ray blocking garment, each roll of Xenolite sheet is routinely sampled and examined for defects using our state-of-the-art x-ray machine. Lite Tech’s “zero defects” quality philosophy ensures that the customer receives the highest, most consistent quality product each and every order.

Another quality and maintenance matter we take into consideration is apron care. Although we are not responsible for daily maintenance of the radiation shielding gear at your hospital or practice, we provide detailed instructions on the best cleansers and cleaning methods to apply.

Many instances of product failure can be attributed to the use of incompatible cleaning products. Read last month’s blog for more information on how to properly clean your x-ray apron.

Xenolite Product Satisfaction

To ensure customer satisfaction and safety, all Lite Tech aprons are covered by a two-year warranty against defects in the core materials or workmanship.
