Need something longer? It's possible but the minimum order quantity is in the thousands. Many university chemistry departments have glassblowers who do work on the side. They can cut a section out of 1 tube & fuse them into another.

Very High Quality! So happy I found these for work. My boss was impressed!
I am SO happy to have found these test tubes from Indigo Instruments. I hadn't heard of them before and had checked the usual large retailers of labware, but couldn't find this size. The price was VERY reasonable, and I appreciated being able to order them in the quantities that I needed, and not in batches of 100/1000/etc. They shipped super quickly and arrived in perfect condition. Couldn't be happier!!
Unfortunately, I ordered the wrong size. (I had taken the lip into account but not the width of the tube itself.) In spite of the order not working out, I found the price to be reasonable and the customer service was excellent. Someone reached out to let me know that it would save money to get two tubes instead of one, and I appreciated that there was a human processing my order who took the time to write me an email.
Thanks for the feedback. We try to review every order in case of product mismatches (tubes & stoppers or test tube racks)?or if there are overlooked cost savings. Glad we could help.
