Perfect for scrap yard sorting

This liquid makes it incredibly easy to distinguish between 304 and 316 steel. The color change is distinct and happens quickly. Great value for the number of tests included.

Works as described

I use this in my small fabrication shop. It accurately identifies the manganese content differences. Just make sure to follow the instructions carefully for best results.

Reliable identification tool

Been using this for months now. Never had a false positive. The bottle lasts a long time since you only need a drop or two per test.

Essential for metal recyclers

Saves us from misidentifying expensive alloys. The 200-test capacity is accurate, and the reagent remains stable over time if stored properly.

Solid laboratory grade agent

Fast shipping and well packaged. The solution is effective for quick field testing. Would recommend wearing gloves when handling.

Good but requires practice

The product works, but interpreting the shade difference took me a few tries to get right. Once you get the hang of it, it is very useful.
