Borosilicate Glass Tube Adapter - Lab-Grade Performance for Scientific and Educational ApplicationsThe USA MOSO Glass Tube Adapter is precision- engineered from laboratory-grade borosilicate glass, delivering the clarity, heat resistance, and chemical stability that demanding laboratory applications require.The 2mm wall thickness sets these tubes apart from thin alternatives. They withstand rapid temperature swings, repeated use, and common lab solvents without cracking or losing clarity. Whether you are running a classroom distillation demonstration, processing essential oils, or assembling a laboratory glassware setup, these adapters deliver reliable, repeatable performance.This 6-pack includes a cleaning brush and individual protective packaging for each piece. Specifications: Material: Borosilicate Glass. Length: 120mm (4.72 inches). Wall Thickness: 2mm. Package: 12 Tubes, 2 brushes.
Product Features
- 12-PACK LAB GLASS TUBE ADAPTER SET: Each set includes 6 precision-crafted borosilicate glass tube adapters and 2 cleaning brushes.
- LAB-GRADE BOROSILICATE GLASS BUILT FOR REPEATED USE: Crafted from the same high-clarity borosilicate glass used in professional laboratories. With a 2 mm wall thickness, these tubes handle rapid temperature changes and repeated heating/cooling cycles without cracking, clouding, or warping. Noticeably thicker and sturdier than standard glass tubes.
- CLEANING KIT: Comprehensive brush set ensures proper maintenance and longevity of the glass tube
- PRECISION GROUND GLASS JOINT AIRTIGHT, LEAK-RESISTANT: Both ends feature frosted ground glass connectors that create a tight, leak-resistant seal on contact. The frosted taper follows standard joint specifications for consistent compatibility with standard laboratory glassware. Pure glass-on-glass connection for clean, stable operation across repeated use cycles.
- VERSATILE LABORATORY APPLICATIONS: Ideal for STEM education, chemistry experiments, essential oil distillation, small-scale liquid transfer, and custom laboratory glassware assemblies. Each tube is individually bubble-wrapped for safe transit.
