I purchased three sizes of test tubes with corks to use as sample vessels at my winery & restaurant. A creative idea we came up with to serve flights and samplers. When I put in my order I was a bit concerned that the glass would be thin and easily breakable. Well, I'm happy to report that the test tube glass is thicker than any I've ever used and is crystal clear, making a great visual for my wines! Excellent customer service and super fast delivery with shipping notification. The high quality box and packaging shows the company actually cares. I am beyond satisfied, unlike purchases I've made at Amazon where items come too often broken, dented or not as described. No more ordering from them or businesses like them for me. Indigo Instruments is on my rolodex of suppliers moving forward.

Thanks for the great feedback, especially on the glass thickness. We made that a priority & our supplier understands how important it is.?

Product arrived very quickly, and was in top condition. The price point was perfect too. Not only would I use this company again, I have recommended it to my friends who teach chemistry. Thank you!

These test tubes are perfect seamless thick glass just larger than the size of my hand and the corks fit well! I put Red Hots in them for a chemistry themed party. I love that they are (no-name) Pyrex and reusable.
