Test Tube With Cap 12mm x 100mm
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.
