## Questions & Answers

**Q: How many individual tests can you do with one bottle?**
A: its hard to gauge an exact number, but you can get quite a few out of one bottle

**Q: WHAT IS THIS?**
A: This apparatus is designed to test respiration protection devices. The bottle shown is the bitter solution which is sprayed into the headcover while the test subject is wearing a respiration device. This product is designed to satisfy OSHA's fit test requirement.

**Q: How can you keep the solution good in between uses? Sometimes i only use every few months and the solution always seems to go bad**
A: Do not remove product seal. Simply use a needle or pin to make a hole in the seal. Squeeze product out as needed. I also use electrical tape to seal bottle cap after use.
