About

• Material: High-quality borosilicate glass (like Type 3.3) for chemical & thermal stability.
• Thermal Resistance: Withstands rapid temperature changes (e.g., autoclaving) without fracturing due to low thermal expansion.
• Chemical Inertness: Resists leaching and pH changes, ensuring sample integrity, unlike cheaper soda-lime glass.
• Design: Available with round bottoms (for even heating) or flat bottoms (for stability).
• Finish: Fire-polished rims for smooth, safe handling.
• Sealing: Often includes threaded necks for secure polypropylene (PP) screw caps, some with foil liners for air-tight seals, or comes as open tubes.
• Packaging: Typically shrink-wrapped and packed in lint-free boxes to maintain cleanliness.
