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.

Thanks for the feedback. We don't pad our prices so we can offer "free" shipping-it's the delivered cost to your door that counts!


Found exactly what I needed. Easy transaction and fast delivery. Well packed too. Would not hesitate to order from Indigo in the future.

No need to be transferred here and there. It's so refreshing and time efficient when you too have a business to run. Thank you and great job everyone at Indigo Instruments.
