Description
The culture tube with screw cap from Osmosis Scientific is a versatile laboratory vessel engineered for secure sample containment, culturing, and storage in a variety of scientific and clinical applications. Constructed from high-quality borosilicate glass, these tubes deliver excellent chemical resistance and durability, making them ideal for repeated use in research, microbiology, and analytical workflows.
Featuring a round-bottom design, these tubes provide uniform structural stability and facilitate better heat distribution during gentle warming or controlled reactions. The accompanying screw cap with chemical-resistant liner creates a leakproof seal that prevents sample loss, contamination, or evaporation — a key requirement for culture growth and reagent storage.
Suitable for a range of laboratory tasks, these culture tubes support processes such as microbial culture preparation, reagent vialing, sample storage, and transport. The glass construction ensures optical clarity for easy visual inspection of contents, while resistance to common chemicals protects sample integrity under routine conditions.Lorem ipsum dolor sit amet, consectetur adipiscing elit.

Frequently Asked Questions (FAQs)
Culture test tubes with screw cap are used in microbiology labs for growing, storing, and transporting microbial cultures under sterile conditions. The screw cap prevents contamination and evaporation, ensuring accurate results in culture media preparation and incubation processes.
Common types of culture test tubes with screw cap include glass culture tubes, plastic test tubes with cap, borosilicate glass tubes, and autoclavable microbiology test tubes. These options vary by material, sterility, and chemical resistance for different laboratory applications.
Screw capped culture test tubes are preferred because they provide a leak-proof seal that prevents contamination and sample loss. They maintain sterile environments during microbial incubation, chemical reactions, and sample storage in microbiology and research laboratories.
Yes, glass culture test tubes with screw cap made from borosilicate glass are autoclavable. They can withstand high temperatures and pressure during sterilization, making them ideal for microbiology culture preparation and laboratory testing procedures.
Culture test tubes with screw cap are available in multiple sizes such as 5 ml, 10 ml, 15 ml, 20 ml, and more. These size options support different microbiological testing, media storage, and sample handling requirements in laboratory environments.
Plastic test tubes with screw cap can be used for microbial culture when made from high-quality, autoclavable polymers. They offer lightweight handling, chemical resistance, and secure sealing for safe culture storage and transportation.
