Borosilicate Glass Culture Tubes

Borosilicate Glass Culture Tubes Specification

Usage
To Hold, Mix, Or Heat Small Quantities Of Solid Or Liquid Chemicals, Especially For Qualitative

Borosilicate glass culture tubes are durable labware made with silica and boron oxide, offering superior thermal shock resistance, chemical inertness, and clarity, making them ideal for cultivating cells, microorganisms, or storing samples without contamination, featuring round or flat bottoms, fire-polished rims, and often screw caps for secure sealing in biology, chemistry, and hematology applications.

Key Features

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.
