Test tube holders are tools specifically designed to hold and secure test tubes. They serve several important purposes:
- Safety:
Protecting hands from heat: Test tube contents can get very hot during experiments. Holders prevent direct contact, protecting hands from burns.
Preventing spills and accidents: Holding tubes securely avoids accidental drops and spills that could cause injuries or damage samples.
- Convenience:
Hands-free experimentation: Holders allow you to perform other tasks without needing to hold the tube constantly.
Precise manipulation: Holders provide stability and control for tasks like pouring liquids or adding reagents.
Multiple tube handling: Holders with multiple slots allow managing and manipulating several tubes simultaneously.
- Organization and storage:
Keeping tubes upright: This prevents spills and ensures accurate measurements.
Easy access and identification: Holders facilitate organized storage and quick retrieval of specific tubes.
Drying and cleaning: Holders allow tubes to dry and air out properly after cleaning.
Types of test tube holders:
Test tube clamps: These are simple and versatile, ideal for single tubes.
They may be made of metal or plastic and have adjustable grips.
Test tube stands: These hold multiple tubes at once, often in rows or grids.
They come in various materials like wood, plastic, or metal.
Test tube racks: These are designed for storing and transporting tubes, often with slots for specific tube sizes.
Test tube holders with handles: These are ideal for handling hot tubes or performing experiments that require mobility.
In summary, test tube holders are essential tools for various laboratory tasks, ensuring safety, convenience, and organization in handling and manipulating test tubes.

What are test tube holders used for?
Test tube holders have much more use in biology than in chemistry. They can allow you to (micro)pipette into many samples at once and generally support many reactions. They allow a test tube to stand up unassisted in a waterbath. The reason a test tube is curved at the bottom, i'd imagine is because if the bottom was square, the grooves would catch and adhere samples and also samples could not be vortexed.
