I haven't heated them so I don't know how they will stand up to a flame. Shipping was faster than I expected. HST's does an excellent job!  - Sunday, February 03, 2013 Know Your Metric SizesReviewed By: Carrie Ayars These test tubes are great quality. The one thing I was dissatisfied with was the size. I know I should have checked out the metric size myself, but the "large" test tube I ordered was not as large as I expected. Order these for sure...just make sure you know what size you are getting.  - Wednesday, January 30, 2013 greatReviewed By: amy they work great!  - Tuesday, January 08, 2013 These are great!Reviewed By: Ethan Gatlin These things are awesome. Not only are they dirt cheap, they are high quality.  - Friday, November 02, 2012 High QualityReviewed By: Bret Bloodgood I was very impressed with the quality of my order. It came quickly, and worked beautifully. The class was a success! Read More Reviews - Friday, March 02, 2012 Good quality but variable size Reviewed By: Diana Some are slightly larger with a flared out top but others are not flared out being slightly narrower. Therefore our #0 SOLID stoppers only fit into the more flared out tubes and not the others. This is just a variation in the test tube, not something you order so you'll have to check yours. We had 3 of 6 test tubes(some we ordered extra) only fit 1/8 of the stopper into it and even that was difficult. So before too much time gets away from you be sure to check that. We have had excellent customer service without added expense and plan to order again in the future. Other than the size variation, these seem be be good quality tubes.
