13 best glass tubing

Glass tubing is a type of cylindrical or tubular glass product used in various industrial, scientific, and laboratory applications. It is known for its high transparency, chemical resistance, and thermal stability. Here's what you should know about glass tubing:

Composition: Glass tubing is typically made from borosilicate glass or soda-lime glass. Borosilicate glass, such as Pyrex, is a popular choice due to its resistance to thermal shock and chemical corrosion. It is often used in laboratory settings. Soda-lime glass is more commonly used for general industrial applications.
Shapes and Sizes: Glass tubing comes in various shapes and sizes, including round, rectangular, and square. The diameter and length of glass tubes can vary significantly, depending on the intended use. Tubes may be as small as a few millimeters or as large as several inches in diameter.
Applications:
- Laboratory Use: Glass tubing is widely used in scientific laboratories for tasks such as creating custom glassware, distillation setups, condensers, and various specialized equipment.
- Industrial Processes: In industrial settings, glass tubing can be used for conveying liquids or gases, particularly in situations where visibility or chemical resistance is important.
- Lighting: Glass tubing is commonly used in neon signs and decorative lighting applications. It can be bent into various shapes and filled with gases to produce different colors of light.
- Art and Craft: Artists and craftsmen often use glass tubing in their projects for its aesthetic appeal and versatility.
Cutting and Shaping: Glass tubing can be cut and shaped to meet specific requirements.It can be heated and bent into desired shapes or cut to precise lengths using specialized tools.
Chemical Resistance: Borosilicate glass tubing is highly resistant to most chemicals, making it suitable for applications involving corrosive substances. It can withstand exposure to acids, bases, and organic solvents.
Thermal Properties: Borosilicate glass has excellent thermal resistance, making it suitable for applications involving high temperatures. It can handle rapid temperature changes without cracking or shattering.
Transparency: Glass tubing is transparent, allowing for easy observation of the contents or reactions taking place inside. This property is especially important in laboratory and scientific applications.
Sealing: Glass tubing can be sealed at one or both ends, depending on the application. Sealing may involve the use of glass-to-glass joints or the addition of stoppers or caps.
Specialized Glass Tubing: There are specialized types of glass tubing designed for specific purposes. For example, quartz glass tubing is used in applications requiring even higher temperature resistance and ultraviolet (UV) transparency.
Handling and Safety: When working with glass tubing, it's essential to take precautions to prevent breakage and injury. Proper cutting, handling, and disposal practices should be followed to ensure safety.

Glass tubing is a versatile material with a wide range of applications in various industries. Its unique properties, such as transparency, chemical resistance, and thermal stability, make it valuable for both scientific and industrial purposes.

User questions & answers

Question:	Are they good for blowing a bubble on the end for smoking
Answer:	The tubes are top quality. If I were going to blow a bubble on the end and close it off to I don't know smoke out of it or make a thermometer, I would go with the 14mm. It would make the od thicker so it would handle heat better. We are using it for sight glasses so our temp. Stay's around 250 degrees so we don't have to worry about the integrity of the glass as much as you. But to answer your question, yes they can be blown and used that way. I tryed it today on some we have broken over the months and the first one I tried with a can of Coleman's fuel on the first one and came up with an epic fail. The second mapp gas was perfect, the 3rd with an oxygen and acetylene torch and It was too hot. But yes they will work. Enjoy
Question:	Why is this order being shipped from china? you need to notate that its coming fron china. now me being all the way in hawaii, its gonna take weeks
Answer:	yeah. The delivery show it will be shipped from China,anyhow we use faster delivery to ship them,usually it can be received in 1-2 weeks.Thanks.
Question:	How well will it hold up with high heat usage on and off on the tip
Answer:	It is very strong glass and holds up well in high heat. Also I dropped a pipe I blew from it on the concrete 6 times before it finally broke.

Question:	Did you intend to send me 6 tubes in each order (2 orders) or was that a mistake? Just wondering, should i send 2 back since i had only ordered
Answer:	Don't know why this is a question that gets sent out to customers. This should go directly to the seller. But since it popped up, let me just give you my 2¢ Don't be a clown. That sarcasm of sending 2 back.... If I were the seller and got a response from you that way, I'd probably feel really stupid for giving you an extra 2 (as maybe an acknowledgement to not fulfilling the original order). It they may have had to source the product from more than one place. Either way, your dry, misdirected attempt at humor will be one of the reasons that sellers stop trying to make up for their shortcomings. I know I just gave you the fine version of my 2¢ worth. Can you send me back a nickel . Keep the extra 3¢ as a token of my regards to your esteem. Aloha
