## Questions & Answers

**Q: What are the dimensions of the vial? Is there a cheaper alternative? 20 dollars seems like a lot for what we're getting.**
A: If you don't need 20 of them, you can get a 6 pack for a lot cheaper: https://www.amazon.com/Aquarium-Pharmaceuticals-API-Replacement-Test/dp/B07G4NGMM8/ref=sr_1_1?keywords=5ml+test+tube&qid=1645582702&sr=8-1 More expensive per tube though.

**Q: Can these be used to store Isopropyl Alcohol for on to go first aid kit? How big is the tube and is it fragile or strong enough for extended use?**
A: I have noticed that the caps, while quite appropriate for water parameter test kits, would not be suitable for long-term storage of any liquid. They leak a bit.

**Q: What test tube rack would be best for these?**
A: I built my own. If you want a cheap hack, get a block of styrofoam and press the top of an open test tube into it at intervals to get the outer diameter perfect. Then cut out the styrofoam to the best depth. Test tubes fit snugly.

**Q: Do you sell just a box of replacement caps?**
A: If you looked for caps already and no results, that means that tubs with caps are sell together. No separate. You might want to contact the API and asked them directly.

The quality is excellent—thick glass that feels durable and resists cracking or breaking during use. The included caps are a great addition, ensuring no spills or accidental contamination of test samples, which is crucial for accurate results. These tubes are easy to clean and work just as well as the original ones that came with my API test kit. What I really appreciate about these replacement test tubes is how versatile they are.
