What is a Borosilicate Glass Tube?

Figure 1: Different-sized borosilicate glass tubes

Borosilicate glass tubes are products/materials made from a combination of silica and boron trioxide and have low thermal expansion co-efficient.

Many people often mistake borosilicate as plastic, but it’s not entirely that. As a matter of fact, borosilicate can contain many other components that can be found in BPA plastic.

Basically, borosilicate glass tubes are borosilicate glass units formed and shaped as tubes and pipes.

Do Borosilicate Glass Tubes Break Easily?

Figure 2: 8mm Pyrex or borosilicate glass tubes

Contrary to popular belief, no, borosilicate glass tubes do not break easily. Borosilicate glass tubes, being made from borosilicate, contain a higher proportion of silicon dioxide, making it more resistant and less susceptible to fractures, cracks, and damages.

Borosilicate glass tubes are even resistant to chemicals. They’re also less soluble, keeping and securing the glass’s structure to remain as it is. You can be guaranteed that its composition would neither be changed nor modified.

That brings us to our next topic, which we’ll discuss the composition and structure of borosilicate glass.

What Are Borosilicate Glass Tubes Made Of?

Figure 3: Borosilicate tubes are made from molten silica sand, soda ash, and alumina

Borosilicate glass tubes are simply borosilicate glass units formed into tubes to be able to better serve their purpose.

The materials involved in the creation or manufacturing of borosilicate glass tubes vary from one manufacturer to another. The common structure of how it’s done, though, would be in this structure:

Boric oxide will be melted along with soda ash, alumina, and silica sand. Of course, highly fluctuating temperatures would be required for this, and they need to be consistent.

Boron is the primary ingredient in the manufacturing of these borosilicate glass tubes because of the fact that it has a higher melting point, but it’s not difficult to find. Not just that, but Boron is also highly resistant to heat, chemical, and pressure giving the glass unit its needed strength and durability.

Are Borosilicate Glass Tubes Safe or Toxic?

Borosilicate glass tubes, similar to standard soda-lime glass are completely safe and non-toxic. It’s a material that can be used by everyone, from children, young adults, and even adults without the fear of causing harm or danger.

Borosilicate glass tubes are extremely safe, and you can use it no matter what environment or atmosphere you are in. There’s no limit to how you can make use of it if it’s within the recommended properties.

Can Borosilicate Glass Tubes Break?

Figure 4: An example of a borosilicate test tube

Just like any other glass units, borosilicate glass tubes can break. Just because they’re stronger, more durable, and less susceptible to damages doesn’t mean they’re already unbreakable.

Yes, they’re more resistant to shock, pressure, and stress, they’re stronger and harder, but they’ll still crack or shatter when they’re subjected to rapid changes in temperature and force.

DID YOU KNOW: Borosilicate glass tubes are stronger and more reliable than tempered glass under temperatures. But you can still perform tempering on borosilicate glass tubes to make them stronger and more durable.

If you want a custom-shaped unit, you can find manufacturers that offer bending borosilicate glass tubes to specific directions, shapes, and bends so that it fits the required shape of the client.

Where Do You Use Borosilicate Glass Tubes?

Figure 5: Borosilicate glass tubes used in the health & sciences industry

Borosilicate glass tubes are used in a wide variety of industries and sectors. But here’s an overview of the most common applications and usages of these borosilicate glass tubes.

Health, Sciences, and Laboratories

One of the main industries where these products are used is the Science and Health industry. Some of the most common ones include test tubes, beakers, syringes, and other lab apparatus.


Borosilicate glass tubes are also commonly used in the electronics industry, mainly for the production of electrical parts and components such as transmitters, pipe coolants, broadcast equipment, and other microelectromechanical system (MEM) parts.


Borosilicate glass tubes are also used to produce and manufacture cookware and bakeware. They can be plates, glasses, utensils, and other kitchen tools. A more formal and official name for borosilicate glass tubes is Pyrex.

Industrial and Manufacturing

Borosilicate glass tubing is also a well-off material used by companies and organizations in the industrial and manufacturing sector. Because of their high heat resistance, thermal shock resistance, and overall durability, they can resist changes and modifications from both internal and external.


Borosilicate glass tubes are also stable and are perfect materials for the fabrication and creation of lenses, slides, and glass units for microscopic and telescopic applications. Other than that, some eyewear manufacturers also make use of these borosilicate glass tubes for the lenses of eyeglasses.

These industries and sectors are only the most common ones that use borosilicate glass tube units. But this doesn’t mean that these are the only applications you have for it! In fact, because of its properties, it’s used for other applications, too.

How Are Borosilicate Glass Tubes Manufactured?

Figure 6: Raw borosilicate glass tube

The procedure of producing and manufacturing borosilicate glass tubes doesn’t need to be as complex and as complicated as how many people think of it.

As a matter of fact, we can simplify the process in a few easy-to-understand steps and methods. They are:

Step 1: Material Gathering

The first step in the process, of course, is to gather all the materials and components needed to produce the borosilicate glass tube products.

This is an integral part of the process because if you miss or lack even one (1) of the components or materials needed, the borosilicate glass tube might not turn out like how you want it to be.

When this process is done, the next step would be to melt and create the borosilicate glass tube…

Step 2: Melting and Borosilicate Forming

When all materials and components are ready, they’re then sent to a furnace with highly fluctuating temperatures to melt and mix them homogeneously.

The working temperature must be at about 550 °F or about 288 to 289 °C, climbing up to about 1,000 °F or around 539 °C.

Step 3: Borosilicate Cutting

Then, this will be formed as a regular borosilicate glass sheet. Let it cool for a few hours and proceed to cut it into tubes and pipes.

Generally, borosilicate glass tube manufacturers use specialized machines and equipment to cut and divide borosilicate and transform it into tubes.

The process usually goes like this:

  1. The borosilicate glass sheet is mounted and set onto the cutting machine.
  2. The cutting machine is set and programmed to the right mode or setting.
  3. Then, the glass material is cut and processed according to how the shape needs to be.
  4. This process will then apply to all borosilicate glass tubes you’ll need.

Step 4: Strengthening and Heat Soak Test

After being formed into tubes and pipes, the next step is to test the strength and the temperature resistance of the borosilicate glass tube.

There are many different tests you can do, but the most common of these would be the heat soak test. Along with this, performing the heat soak test also helps minimize risks of breakages on glass units that are heat treated.

This process entails placing the newly formed borosilicate glass tubes inside a chamber and the temperature is set to about 550 °F or 287 °C, expediting or accelerating the expansion of nickel sulfide.

Step 5: Coating Process

After that’s done, the next step would be the coating of the tubes or pipes. The process of doing so would depend on the type of coating the client is requiring.

This step can also be what you can do to color the borosilicate glass tube to the color and style that you want.

Step 6: Lamination Process

Then, the next step is to laminate the borosilicate glass tube. Lamination is usually done by sticking and bonding another layer of borosilicate glass, forming a permanent bond, making it stronger than what it is.

This helps hold the entire glass structure, keeping the 2nd layer free from any type of inconsistency should it be subjected to force, pressure, and stress.

Step 7: Testing and Inspection

Last, but most definitely not least is to test and inspect the borosilicate glass tube to see if it’s within the expectation of the client. Many tests and experiments are done to ensure that the borosilicate glass tube befits the needs of clients.

This is done usually before packaging and distribution to avoid problems with client supplication.

This is the usual 8-step process of how borosilicate glass tubes are made and manufactured. It’s not the process followed by all manufacturers and suppliers, but this is the basic structure of how borosilicate glass tubes are made.

NOTE: If you are interested to know how your manufacturer produces their borosilicate glass tubes, contact and ask about it with your respective manufacturer.

Is Borosilicate Glass the Same as Pyrex?

Figure 7: A dual open-ended Pyrex glass tube

Yes, borosilicate glass is actually the same as Pyrex. The product just becomes “Pyrex” when you perform bending of the borosilicate glass tube. For the bending or the shaping, the end-result will depend on what the client is looking for.

For you to understand it better, borosilicate glass and Pyrex are the same. The difference is that Pyrex is actually a subset of borosilicate glass; you can think of it as Pyrex being the branded version of standard generic borosilicate glass.

That being said, the process of producing Pyrex and borosilicate glass tubes is the same. Both are made and designed to have the same thermal properties. If you thought that these two (2) would have major differences, you’re wrong!

What Sizes Can You Purchase Borosilicate Glass Tubes On?

This is an abstract question. Borosilicate glass tubes have over 100 different sizes, all of which have their own purposes. The most common sizes range from 4mm inches in diameter, about 0.9mm thick to about 325mm in diameter to 9.0mm thick, as well as any size in between.

What this simply means is you do not have any limitations on the size of the borosilicate glass tubes you can purchase. There’s a heap of sizes and measurements to buy.

The exact size you want to go for shall depend on the application you’ll have for it. If you’ll use it as laboratory apparatus, you want to get borosilicate glass tubes that are about 1mm thick and about 6mm in diameter.

What Colors of Borosilicate Glass Tube Can You Purchase?

Figure 8: A brown or rust-colored borosilicate glass tube

There’s a heap of colors for borosilicate glass tubes you can get on the market. In fact, some businesses use colored borosilicate glass tubes for the purpose of grouping together and categorizing some products and materials.

Akin to the sizes of these borosilicate glass tubes, there’s also no limit if you want colored borosilicate glass tubing. You can purchase red borosilicate glass tubes, clear borosilicate glass tubes, blue borosilicate glass tubes, yellow tubes, and many more!

To give you an example, red borosilicate glass tubes are used for chemical and laboratory apparatuses. Most businesses and organizations utilize this type of color-coding to identify specific products, too!

The most common colored borosilicate glass tube examples include, but are not limited to:

  • Red Borosilicate Glass Tubes
  • Yellow Borosilicate Glass Tubes
  • Blue Borosilicate Glass Tubes
  • Transparent Black Borosilicate Glass Tubes
  • Opaque Black Borosilicate Glass Tubes
  • Green Borosilicate Glass Tubes

The list goes on! There’s never a limit to what colors of borosilicate glass tubes you need! If your manufacturer is skilled in producing a black transparent glass tube, then by all means go for it! This is the importance of why it is important to ask your manufacturer about the colors they can produce and help you with.

Inquire about it by contacting and asking your borosilicate tube supplier the colors they have available. Better yet, ask them for a sample colored-borosilicate glass tube before ordering.

Here at SXET, we have a wide range of colors available in our color spectrum. There are tons of colors, hues, and shades we play with! We don’t have any limits on the borosilicate glass tube colors we produce.

Let us know what color you’re looking for and we’re more than happy to help you with it!

What Are the Different Physical Characteristics of Borosilicate Tubes?

The physical characteristics of borosilicate glass tubes vary from product to product, as its results will depend on how the product, or the borosilicate glass tubes are manufactured.

Here’s a quick list of the properties of borosilicate glass tubes you want to know about.

General Properties

These are properties that are not particularly grouped because they’re generally things that are common across different types of glass units.

Mechanical Properties

They’re physical properties that materials usually exhibit when force and pressure are applied. In simpler words, mechanical properties are the reactions that these products exhibit when external forces are applied.

Thermal Properties

These are properties that is exhibited by materials in relation to how they are conductive of heat and temperature. So, these thermal properties are properties that happen when heat passes through the borosilicate glass tube.

Electrical Properties

Last, but most definitely not least are the electrical properties. To make it simpler, these are properties that measure a glass’s ability to conduct electrical current.

Can Borosilicate Glass Tubes Be Tempered?

Figure 9: Tempered borosilicate glass tubes

Yes, you could temper borosilicate glass tubes to improve and enhance their strength and durability. Doing so can reinforce them to withstand temperature, force, stress, and pressure without it being fractured.

Commonly, the tempering of borosilicate glass tubes are done for applications where they’re used for chemistry, laboratory, and sciences.

In some situations, the construction and structural industry also makes use of tempered borosilicate glass units because they’re stronger, more durable, and less likely to crack and fracture under stress.

How to Know If a Glass is Borosilicate Glass Tube?

Glass experts and glassmaking professionals use a series of tests and experiments to identify whether a material is made from standard soda-lime glass or borosilicate glass.

Here are a few methods you can do to identify if a material is made from borosilicate glass.

Liquid Submerging Method

One method used by experts is by submerging the piece of glass into a liquid that has the same refractive index – glycerin, for example and see if the glass disappears. If it does, then that simply means that the glass is made from boron.

Other than glycerin, you can also use dry benzene and mineral oil.

Temperature Method

Another method experts do is to check if the glass is able to withstand temperature changes and modifications without changing the volume, shape, and density.

To do this, place a material in question inside the refrigerator for about 1 to 2 hours. Then, take it out and pour boiling water on it (if it’s a container, pour boiling water inside).

If the glass material breaks, then it’s not a borosilicate glass tube. If it remains the same shape without any cracks, fractures, or signs of damage, then it is made from borosilicate glass.

Can You Cut Borosilicate Glass Tubing?

Yes, borosilicate glass tubes can be cut, reshaped, and reformed all according to how you want and need them.

Generally, borosilicate glass tube manufacturers use automatic machineries and equipment to cut these glass tubes to the required shape and form. But if you want to do the cutting on your own, you can use a sharp cutting object and place it on an elevated level.

As a matter of fact, cutting it is a simple and easy job. Here’s how it’s done:

  1. Prepare all the cutting materials needed for the procedure.
  2. When that’s all done, mark the glass tube where you want to do the cut.
  3. With the cutting tool, trace out the marking you’ve done.
  4. Continue tracing it using the cutting tool until you notice it come off.

NOTE: If you’re using a power cutting tool, simply trace out the marking you’ve done on the glass tube to cut it.
