Welcome to our curated selection of Pyrex glass tubes, where laboratory-grade precision meets industrial reliability. This category features packs of six rimmed test tubes in three versatile sizes: 13 x 100 mm, 18 x 150 mm, and 25 x 150 mm. Whether you're equipping a research lab, educational setting, or industrial workspace, Pyrex delivers unmatched thermal shock resistance and chemical durability, ensuring your experiments and processes run smoothly without compromise.
Why Pyrex Stands Out in Glass Tubes
Pyrex has built a legendary reputation for borosilicate glassware since the early 20th century, prized for its low thermal expansion and superior strength. Unlike standard glass, Pyrex tubes withstand rapid temperature changes—from freezing to boiling—without cracking, making them indispensable in demanding environments. These tubes are part of our expansive Industrial & Scientific offerings, tailored for professionals who prioritize safety and performance.
Key Features to Consider When Shopping
When selecting Pyrex glass tubes, focus on dimensions, rim design, and pack quantity to match your needs. All models here feature a sturdy rim for easy handling and pouring, reducing spillage risks. The borosilicate composition ensures clarity for precise observations and resistance to most acids and bases.
- Material Quality: Borosilicate glass for heat resistance up to 500°C.
- Rim Design: Beaded rim for secure stoppering and pouring control.
- Pack Size: Convenient packs of six for cost-effective bulk use.
- Dimensions: Choose based on sample volume—smaller for micro-tests, larger for substantial reactions.
These attributes make Pyrex tubes a go-to within our Hydraulics, Pneumatics & Plumbing category, bridging lab precision with fluid-handling applications.
Comparing Pyrex Test Tube Models
Our Pyrex lineup offers tailored options to fit diverse workflows. The 9800-13 (13 x 100 mm) is compact, perfect for small-scale reactions or educational demos, holding about 10-12 mL. Step up to the 9800-18 (18 x 150 mm) for mid-volume needs around 30 mL, ideal for general chemistry. For larger samples up to 50 mL, the 9800-25 (25 x 150 mm) provides ample capacity without sacrificing stability.
| Model | Dimensions | Approx. Capacity | Best For |
|---|
| 9800-13 | 13 x 100 mm | 10-12 mL | Micro-experiments, storage |
| 9800-18 | 18 x 150 mm | ~30 mL | Standard lab tests |
| 9800-25 | 25 x 150 mm | ~50 mL | High-volume reactions |
Selecting the right size depends on your setup—mix packs if versatility is key. These tubes integrate seamlessly into broader systems found in our Tubes, Pipes & Hoses collection.
Common Use Cases for Pyrex Glass Tubes
Pyrex tubes excel in laboratories for culturing, heating, and mixing. In educational settings, they support safe student experiments. Industrially, they're used in quality control, sample prep, and fluid dynamics testing within Tubing applications. Their autoclavable nature simplifies sterilization, while uniformity ensures repeatable results. For specialized glass needs, explore our parent Glass Tubes category.
Frequently Asked Questions
What makes Pyrex glass tubes superior to regular glass?
Pyrex's borosilicate formula offers three times the thermal resistance of soda-lime glass, preventing cracks during heating or cooling cycles common in labs.
How do I choose the right Pyrex test tube size?
Opt for 13 x 100 mm for small volumes, 18 x 150 mm for everyday use, or 25 x 150 mm for larger samples. Consider your typical reaction scale and equipment compatibility.
Are Pyrex tubes compatible with lab equipment?
Yes, the rimmed design fits standard stoppers and racks. They're autoclavable and resistant to most reagents, outperforming cheaper alternatives.
Pyrex vs. competitors: What's the difference?
Pyrex leads in purity and consistency, backed by Corning's heritage. Competitors may cut costs with thinner walls, risking breakage under stress.
What warranty or support does Pyrex offer?
Pyrex products come with manufacturer quality assurance; contact Corning support for defects. Their durability minimizes replacements, ensuring long-term value.
