Very happy with the quality and price of your glass. That's why I keep reordering from indigo instruments.

The test tubes were exactly what I was looking for. I agree with Doug - they were packaged very well and no damage occurred during shipping. And they were shipped immediately and arrived in a very short time frame.

Helpful staff, product was well packaged and everything arrived unbroken. Quick shipping too!

Test tubes were very well packaged and arrived in perfect condition. I appreciate that they did not have any markings since they are to be used as vases.

Good to hear they got there ok & you're happy with their having no markings. We realized years ago that the esthetics demanded they be completely blank.


Good quality and still have not broken any with thermal shock

They were exactly as described and shipped out right away. My son uses them for antkeeping and they were perfect for his needs.

We've ordered without markings for years for that reason. Most sources only offer this in disposable soda lime glass culture tubes that break easily.

test tubes were exactly as described, they were shipped the next day with no breakage. Have purchased from Indigo n the past & will do so again in the future.

The durability of lab glass is essential to making quality horticulture display stands that last. Bulk pricing made the test tubes very affordable and the cost of the overall project minimal. Competitively priced and shipped promptly. I purchase all my lab glass from Indigo!
