Glass culture tubes with screw cap and flat bottom
These culture tubes, also known as culture tubes or preparation tubes, are made of high-quality borosilicate glass 3.3 (ASTM E438 TYPE 1, Class A). This glass type is known for its excellent chemical and heat resistance. The tubes come with a black screw cap made of durable polypropylene that has a PTFE/Teflon insert. You then have a tight seal which makes the cap leak-proof.
The glass tubes are designed for laboratory applications where there is a need to store liquids, chemicals and samples in safe and stable conditions. They are resistant to temperature changes. This makes the glass tubes suitable for situations where samples need to be stored under different conditions without the risk of cracking or crazing of the glass.
Benefits and application
- Safe storage: The tight-fitting screw cap prevents evaporation and contamination of contents, which is essential in laboratory environments.
- Chemical resistance: Borosilicate glass 3.3 is known for its high acid and alkali resistance, making it ideal for working with aggressive chemicals.
- Applications: Suitable for use in microbiology, chemistry and biotechnology where precise and stable storage conditions are essential.
- Flat bottom: Provides extra stability on lab tables and shelves, reducing the risk of them tipping over.
Specifications for glass culture tubes
- Glass: ASTM E438 TYPE 1, Class A, Borosilicate glass 3.3.
- Lid: Black polypropylene screw cap with PTFE/teflon insert.
- Design: Flat bottom and leak-proof seal.
- Sizes: Available in different volumes.
Note: Glass culture tubes are primarily recommended for storage and transport of samples and liquids and should not be used for heating. This ensures optimal durability and protection of the samples.
