Low Borosilicate Glass Tubes is a tubular form of borosilicate glass. Borosilicate glass has high chemical durability, high thermal shock resistance, low coefficient of thermal expansion and excellent optical properties. Borosilicate Glass Tubes are used in scientific laboratories and industrial processing due to its resistance to chemical corrosion and ability to withstand rapid temperature changes. They are also used in lighting applications because of borosilicate glass's high light transmission.
It is a popular material for use in laboratory equipment, medical devices, cookware, and other consumer products that rely on its heat-resistant properties, such as glass baking dishes, bowls, glass coffee pots, and not least, glass hookah pipes.
Benefits of Low Borosilicate Glass Tubes
Optical Clarity
Low Borosilicate Glass Tubes It’s clear to see why glass is a good solution when it comes to visibility (how could I resist this pun). Compared to the array of plastics, metals and other materials of construction, glass provides a smooth surface that offers an unobstructed view of what is going on inside the equipment, enhancing the level of observation in any process.
Cleanability
Some materials of construction can pose housekeeping issues when it comes to ease of cleaning. Low Borosilicate Glass Tubes The anti-stick, nonporous surface makes borosilicate glass a popular choice for GMP compliant applications. And its transparency allows you to see when equipment needs to be cleaned without the need for interrupting the process and performing an internal inspection.
Compact Design
Low Borosilicate Glass Tubes Compared to systems built using alternative materials of construction, glass components are much more compact making a glass system significantly smaller. This is especially beneficial in facilities that are facing space constraints as well as work areas where headroom can become an issue.
Corrosion Resistance
Similar to the properties of glass-lined steel, glass equipment provides unsurpassed corrosion resistance to water, neutral and acidic solutions, concentrated acids and acid mixtures, and to chlorine, bromine, iodine and organic substances. Its resistance to chemical attack is superior to that of most metals and other materials, even during prolonged periods of exposure and at temperatures above 100 °C. There are only a few chemicals which can cause noticeable corrosion of the glass surface - hydrofluoric acid, concentrated phosphoric acid and strong caustic solutions at elevated temperatures.
Applications of Low Borosilicate Glass Tubes
Sight Glasses:
Used in various industries to view processes within vessels and pipelines without opening them. Borosilicate sight glasses provide clear visibility and withstand harsh environments.
Level Gauge Glass:
Essential in monitoring fluid levels in tanks and boilers. They are designed to endure high pressures and temperatures.
Red Line Tubes:
These tubes feature a red line for enhanced visibility of fluid levels, critical in high-precision applications.
High Pressure Tubes:
Employed in systems where they must endure extreme pressures without compromising integrity.
Heavy Wall Sight Glasses and Boiler Glass Tubes:
These provide additional thickness to withstand higher mechanical stress and thermal shock in boilers and other high-pressure environments.
Borosilicate Glass Tubes for Laboratory Work
Right from 16th Century, chemical research teams have used glass containers for a very basic reason; the glass container is transparent, almost invisible. And so the contents and the reaction are clearly visible. But because chemists must heat, cool and mix chemical substances, ordinary glass is not always adequate for laboratory work.
Laboratory work requires apparatus made in a glass – which can readily be moulded into any desired shape or form, which offers maximum inertness when in contact with the widest range of chemical substances, which can withstand thermal shock without fracture and high temperature work without deforming, and which will be resilient enough to survive the everyday knocks to which it will be subjected in normal laboratory handling, washing and sterilizing processes.
Borosilicate glass represents unmatched standardized glass for construction of plant and piping in the chemical, dyestuff, food pharmaceutical, petrochemical industries. Borosilicate glass is also very widely used for scientific applications. Made from low thermal expansion borosilicate glass its intrinsic qualities of resistance to physical and chemical attack and ability to stand thermal shock make it an ideal material of construction for scientific and laboratory apparatus, for industrial applications like syringe manufacture, gauge glasses, photo printing cylinders, petromax lantern chimneys, explosion-proof lighting covers and for fabrication of chemical process plant and piping.
Dimensional Tolerances:
Borosilicate tubes are manufactured with tight tolerances to ensure they fit precise applications. Dimensions can vary based on requirements, ranging from small-diameter tubing for laboratory use to larger diameters for industrial sight glasses.
Thermal Expansion:
As mentioned, borosilicate glass has a low coefficient of thermal expansion, typically around 3.3 × 10⁻⁶/K. This ensures minimal expansion and contraction with temperature changes, maintaining structural integrity.
Chemical Composition:
The typical composition includes about 80% silica (SiO2), 13% boric oxide (B2O3), 4% sodium oxide (Na2O), and 2-3% aluminum oxide (Al2O3). This composition gives borosilicate its unique properties.
Mechanical Properties:
Density: Approximately 2.23 g/cm³
Elastic Modulus: About 63 GPa
Poisson’s Ratio: Around 0.2
Hardness: Knoop hardness of 480 kg/mm²
Optical Properties:
Refractive Index: Approximately 1.47
Transmission Range: Transmits light from UV to infrared, depending on the thickness and specific composition.
What is the Difference Between Regular Glass and Borosilicate Glass?
Besides the added boron trioxides, borosilicate glass stands out from regular glass for a few important reasons:
Durability
First and foremost, borosilicate glass is more durable than standard glass. Most objects made from borosilicate glass can survive a knock or two without chipping, cracking, or shattering.
Heat Resistance
As we’ve mentioned above, borosilicate glass is prized for its ability to withstand incredibly high temperatures without cracking or melting.
Stability
Borosilicate glass is highly stable, meaning it won’t leach chemicals or toxins. In fact, it’s so stable that it’s used in nuclear reactors to transport nuclear waste without leaching radiation.
Low alkali borosilicate glass: Refers to SiO2-B2O3-R2O composition, with low coefficient of linear expansion, low dispersion, good chemical stability, high thermal stability, and good electrical insulation. It is used as heat-resistant cookware, ampoule glass, optical glass, solar panels, and collectors.
Alkaline earth borosilicate glass: Refers to the SiO2-B2O3-RO component used to prepare optical glass and low-temperature glaze, used in crystalline powder solder, rectifier, and electronic device passivation.
Lanthanum borosilicate glass: Refers to the SiO2-B2O3-La2O3-RmOn component, which has high refractive index, low dispersion, good chemical temperature resistance, and low devitrification ability.
Rare earth doped borosilicate glass: Laser glass based on SiO2-B2O3-RmOn, doped with Pr and Nd, nonlinear optical glass of Au, Ag, Cu, luminescent glass of CdS, ZnS: Mn nanocrystals.
The Difference Between Low Borosilicate Glass Tubes and Medium Boron Silicon Medicine
The main difference between medium borosilicate glass and low borosilicate glass is that they have a higher content of boron trioxide, higher thermal and chemical stability, and stronger ability to withstand temperature fluctuations. Therefore, the produced medicine bottles also have certain performance differences.
Chemical properties:
The national standard for water resistance on the inner surface of low borosilicate small bottles is 2.6m, while the national standard for water resistance on the inner surface of medium borosilicate small bottles is 1.3m. Simply put, "water resistance" refers to the harmful alkaline oxides such as potassium and sodium adsorbed on the inner wall of the small bottle during the subsequent processing in the bottle factory. The fewer the oxides, the better the water resistance. Good water resistance is beneficial for various indicators such as drug acidity, clarity, and stability.
Physical performance:
The size tolerance of the medium boron small bottle is very small. For example, the outer diameter tolerance standard of 16 tubes is plus or minus 0.14m, with a crystal clear color and high strength, which is better matched with production equipment. The low boron silicon tolerance is large and unstable between batches. For example, the outer diameter tolerance standard of 16 tubes is 0.3mm, with a greenish color, which is difficult to match with imported or high-end equipment.
