100ml Water Sampling, Safety Test Bottles with Sodium Thiosulfate for Chlorine Neutralization,Sterile,100/Case, Cat #: 89-9001

I've been ordering these bottles for a while now and so far so good (with Thio and without Thio). They come with certification and Lot number with is very important for the log books. Hopefully it becomes "prime" soon.

We have ordered once, the bottles arrived quickly. The bottles were packaged well, was no breakage or cracks in the bottles. We lot checked for sterility, volume, fluorescence and sodium thiosulfate efficiency; all was as advertised. Note that the bottle tops do fluoresce under a black light, but not the bottle itself.
