Metal Testing Kit

Supplier’s certifications and importer's promises are not enough. Testing alloy content with undeniable, foolproof, reliable kits from Koslow Scientific provides you with peace of mind. Order the Stainless Steel Tank Tester  ID Kit and test it yourself! For over 50 years companies from pharmaceutical to aerospace have relied on Koslow kits. No need for expensive XRF equipment. No need to file off samples to mail to metallurgical testing labs. A chemical spot test is a diagnostic test that is performed by the electro-spot method. Verify your stainless steel 316 incoming and outgoing stock. Use the quality testing solutions that have been ordered by engineers, fabricators, welders and scrap metal dealers. Sensitive and interference-free chemical color tests detect the alloying components. A color develops as a result of a chemical reaction and, generally, the intensity of the brightness can be used to estimate the amount of alloying component present. Spot tests are more straightforward, faster and cheaper than chemical analysis. The density of color reactions is correlated to nominal composition.  Spot tests are usually sufficient for alloy identification differentiation and verification. The 1596 Kit includes two metal samples to be used as a testing reference. Working with the 201 and 304 Stainless Steel ID Kit Calibration Standard will vividly demonstrate a positive result.

Great Product!

This product has worked so well for us. We have several large steel tanks at our facility and we found that the Koslow kit is the most cost-effective way to verify SS304. Thanks Koslow

Confirms SS 304

This product has been great for confirming SS 304 for the tanks and pipes at our facility. It has been working well for about a year now, and Koslow was great at answering any questions we had when getting started.
