Glass extraction tubes – Why Duran Schott Glass?

Chinese vs. American or German glass is not referring to where the glassblower makes your piece. It is referring to what the piece is made from.

I use Duran Schott clear tubing and rod and American made colors, like Troutman, Northstar, and Paramore.
Many American glassblowers make pieces out of Chinese glass, because it is quite a bit cheaper than Duran Schott.  Duran Schott makes a far superior product than Chinese Glass and creates a better product. It takes a skilled glassblower to make a great piece of functional glass. Clint has 18 years of experience blowing glass. He anneals the glass properly. He takes great care to make our customers the finest products. Eugene Oregon is the glassblowing mecca of the world.

Simax and Pyrex are one step below Schott in quality (in my opinion). Any of these are better than Chinese. Duran Schott Glass melts silky smooth. It doesn’t bubble or crack easily. It is more durable.

All of our glass is made from high quality Borosilicate glass.  was first developed by German glassmaker Otto Schott in the late 19th century.

  • Highly resistant to temperature fluctuations and heat. Schott is ideal laboratory glassware for chemical processes and other processes where large amounts of heat are generated.
  • Highly resistant to corrosion caused by water, acids, saline solutions, alkaline solutions and organic substances, for durable products in corrosive environments.
