Customer Questions & Answers

Customer Reviews

These really are more of a culture tube than a test tube.
J. Strickland
These are run-of-the-mill test tubes, but it's difficult to get a tight fit with the stoppers, which tend to try to pop right back out.
JOSHUA S GOLDSTEIN
The glass was of good quality and I had no fear of them breaking easily.

Pro- Stoppers seem to be of adequate quality - In fact I'm using them in my quality test tubes right now!
Pro- some test tubes arrived in the condition expected

Con- Four test tubes were completely shattered in the box.
Con- This is arguably a culture tube, not a test tube. One assumes test tubes have flared lips to allow for an easier time pouring fluids. The lip on this 'test tube' is so thin that I am extremely worried that the tube will shatter whenever a stopper is inserted for an air tight seal.

I am unsure if I will be using this product at all, the glass lip is thin enough to concern me.

When i started using the tubes they seemed fine expecially the stoppers but after a couple of uses the "pyrex" cracked. The test tubes were put directly in front of a propane torch then but to cool in an ice water bath. Pyrex is made to withstand this temp change but whatever material these are did not.

The test tubes came in a size smaller than ordered so the stoppers did not fit. I did not realize this until a week after receiving the order. I called them and informed that tubes size will work but stoppers did not and to complicate matters, I needed them in two days. They overnighted the right size stoppers to me. That is good customer service.

Thanks

These Pyrex tubes and rubber stoppers are superior to cork stoppers ( I dislike cork). While they do shatter if dropped they are well made and are fairly tough if you are responsible with them. The seller provided very clear and smooth glass tubes, shipped safely!

Several arrived broken and the quality of the glass is questionable at best. These are labeled as Pyrex which doesn't seem accurate. Very disappointing.

Packaging is excellent. All of them arrived intact. Rubber stoppers can be difficult to remove. It seems some stoppers work better with some tubes. I broke 1 tube while trying to pry a stopper out. Not a big mess.

I bought these for a project and just bought enough for the gumball I needed but three out of 60 came broken! I was disappointed that glass was not packed better!
