I've been happy with the quality of the glass I've gotten from Indigo Instruments and happy with their speedy delivery. This is my second 5-star review.

Very happy with products and service. Will be back for more assorted sized test tubes.

Excellent test tubes for micro experiments and making ampoules. Like the fact you can buy a few of each size instead of a full box.
