## Questions & Answers

**Q: How much vacuum can it take without damage?**
A: All you have. It's thick and strong. I like it.

**Q: What is the inside diameter of the neck or what size rubber stopper fits the opening?**
A: Inside diameter is 1.34 inches (34.22mm)

**Q: What size tubing does this require?**
A: 3/8 PE tubing works well and won't collapse. Get a 4" length of that, adapt it down to the much more flexible 1/4 PE tubing with a push connector. Run that to a push connect one way valve with it's arrow pointing to the pump. That way a malfunctioning pump can't back-feed pump oil into your project.

**Q: I see the package dimensions posted.  What are the dimensions of the actual flask?  Height and base diameter?**
A: 11in high with a 7in base diameter.

I needed to filter and degas small amounts of toxic material; this flask fits the bill perfectly. It has a wide mouth as well for easy pouring; fast delivery was a plus.
