## Questions & Answers

**Q: Approximately how many tests can you do with this product?**
A: Every tube for 3-5 tests. There are 6 tubes in the  package.thanks

**Q: Can this be used to fit test N95 masks?**
A: Yes

**Q: What's the difference between this product, 12K, and their other product designated 11K?**
A: The saccharine and bitrix solutions both have a “fit test solution” and a “sensitivity solution”. I think 12k is for the fit test solution to be used during the actually fitting, and the 11k is the sensitivity solution used to determine a threshold before fitting.

**Q: What is difference between test vs sensitivity? And do I need a machine to spray it?**
A: Not sure what difference is, but they are designed for two parts of the test - sensitivity, w/o a respirator, and full test w/respirator.
You will need the atomizer to use these vials
