Pyrex 9800-13 13 X 100 mm Glass Test Tube with Rim (Pack of 6)

Good glass melts doesn’t crack

These are a bit small, but it's my fault for not reading description thoroughly. The glass is phenomenal though! They are hard to break also, unless you heat them up and don't cool down properly.A+!

These were quality test tubes. Packaging could have been a little better but they survived the trip. Only knock was the size was smaller than expected. That as much falls on me and my research as the description.I had to return these but would have no problem ordering them again in an appropriate size. Minus that one glitch, the transaction was flawless.

Glass to thin for been a pyrex tube

Right size good glass can be use for many things. Heat resistant and cold

It was exactly what I wanted, exactly what I got, and a good value.

Product is as advertised but 3 of the 6 I ordered came chipped they were just put in plastic and tied with tape and all the banging together chipped the rims.

I used these testubes to make a plant propogation station and they were perfect! Great rim on them so they don't fall through the holes. 1/2 drill bit was just right with a bit of sanding! The larger test tubes in the pic are the same brand size 20mm x 200mm
