Test Tube With Cap 18mm x100mm
Test tubes with caps are used for securely storing, transporting, and mixing liquids or solid samples in laboratories and industrial settings.
The caps, which may be screw-on, snap-on, or stopper types, prevent contamination, evaporation, and leakage.
They are also utilized for centrifuging samples, culturing microorganisms, and organizing small items.
Key Uses and Applications:
Sample Storage and Transport: Secure screw caps make them ideal for storing and moving samples without risking leaks.
Laboratory Analysis: Used for holding, mixing, and heating chemical or biological samples.
Centrifugation: Specialized, high-strength tubes with caps are used to separate sample components in a centrifuge.
Microbiology: Used in biotechnology and bacteriology laboratories to cultivate and protect cultures from contamination.
Medical Diagnostics: Specific tubes (like blood tubes with colored caps) are used for collecting, storing, and processing blood, tissue, or urine samples.
Field Testing: Durable plastic versions are used for collecting environmental samples like water or soil.
Organization and Industrial Use: Used for storing items like beads, crafts, spices, or creating favors.
Types of Caps and Their Purposes:
Screw Caps: Provide a secure, often leak-proof seal, ideal for long-term storage and transportation.
Snap-on/Press-on Caps: Offer a simple, effective seal, suitable for quick, temporary covering.
Rubber/Silicone Stoppers: Provide a tight, reliable seal for general-purpose use.
Vent Caps: Allow for airflow while still maintaining a barrier against contaminants, useful for cell cultures.
These tubes are commonly made of glass or durable, transparent plastics like PET, making it easy to identify contents.
