FAQs

1. What exactly is a reagent tube, and how does it differ from a regular test tube?

A reagent tube is specialized laboratory glassware or plastic container designed to store, mix, or react with chemical reagents—often with features like thicker walls, grading, screw caps, or chemical-grade materials—and differs from generic test tubes in its enhanced chemical compatibility and ability to maintain reagent purity under varied conditions like temperature, light, or vacuum.

2. How do I choose the right cap for a reagent tube?

Select a cap based on the type of reagent (e.g., corrosive, volatile, light-sensitive), storage temperature, need for sterility, chemical resistance, thread compatibility, leak-proof requirements, security features, and applicable regulatory standards.

3. Is there a maximum temperature that reagent tubes can handle?

This depends on the material: borosilicate glass can generally endure high temperatures (up to ~500 °C) and is ideal for heating or autoclaving, while plastic tubes like polypropylene typically tolerate temperatures only up to ~120–140 °C before deformation or degradation.

4. Are certain reagent tubes incompatible with specific chemicals?

Yes. While glass tubes resist most chemicals, they're vulnerable to strong alkalis or hydrofluoric acid. Plastic tubes may resist impact but can react with organic solvents. Always verify the chemical compatibility for both the tube and closure materials for safe use.

5. How should reagent tubes be labelled and stored to ensure reagent integrity?

Label tubes clearly with chemical identity, concentration, preparation date, and hazards using solvent- and temperature-resistant ink or labels; for long-term or cold storage, use cryo-labels or etching. Store tubes upright in clean, dry, temperature-controlled (and if needed, light-protected) areas, ensuring caps are sealed to prevent evaporation or contamination.
