Frequently Asked Questions

How do I choose the right type and size of test lab tubes for my application?

Select tubes based on material (glass for chemical resistance and heat tolerance, plastic for impact resistance and disposability), volume (common sizes 5–50 mL), and neck type (standard or screw-cap) to match your samples, temperature range, and compatibility with centrifuges or rack systems

What materials are available and how do they affect chemical compatibility and temperature limits?

Borosilicate glass offers broad chemical resistance and high-temperature use; soda-lime glass is less resistant and cheaper; polypropylene and polystyrene plastics resist many aqueous chemicals and are impact-resistant but have lower maximum temperatures and variable solvent compatibility

Are these lab tubes suitable for centrifugation and what should I check before using them in a centrifuge?

Only use tubes rated for centrifugation; check the manufacturer's maximum relative centrifugal force (RCF or g), tube shape and wall thickness for rotor fit, and ensure caps or seals are secure to prevent leaks during spin

How should I clean and sterilize reusable test tubes to maintain performance?

Clean with appropriate detergents and brushes, rinse thoroughly, and sterilize according to material limits—autoclave borosilicate glass and autoclavable plastics at specified temperatures, or use chemical sterilants for heat-sensitive plastics; inspect for cracks before reuse

What packaging and cap options should I consider for storage and transport?

Look for screw caps, snap caps, or silicone/PTFE-lined caps for chemical resistance and leak prevention; consider tubes sold in racks or foam inserts for organized storage and secure transport, and choose clear or amber tubes if light sensitivity is a concern

How does price vary across test lab tubes and what should I expect for quality versus cost?

Prices vary by material, volume, and brand; budget options can be under $50 for multi-packs of plastic tubes, while higher-quality borosilicate or certified sterile tubes cost more; prioritize material and ratings for applications needing chemical resistance or sterility

What labeling and measurement features are useful when selecting lab tubes?

Choose tubes with molded graduations or writable areas for consistent volume tracking, and consider pre-printed or erasable label surfaces and barcode-compatible options for inventory and sample management
