Frequently asked questions
Are these tubes resistant to harsh chemicals?
Yes. These tubes are crafted from premium-grade polypropylene, which provides superior chemical resistance compared to polystyrene. They are fully compatible with:
- Organic solvents
- Strong acids (excluding oxidizing acids)
- Alkalis and alcohols
- Ketones
- Chlorinated/aromatic hydrocarbons
Are these tubes suitable for high-volume lab work?
Absolutely. These tubes are precision-molded by Caplugs Inc. to ensure consistency and reliability. Supplied in bulk, they are designed as a cost-effective, high-quality solution for busy laboratories performing routine diagnostic procedures and analytical chemistry.
Can I use these tubes in a standard centrifuge?
Yes, their 12 x 75 mm profile is a standard dimension compatible with most common benchtop centrifuges and standard laboratory test tube racks.
What is the primary benefit of the polypropylene construction?
The key advantage is durability and versatility. Unlike polystyrene, which can be brittle or reactive, the high-quality polypropylene used here allows these tubes to withstand a much broader range of aggressive chemical agents, making them safer and more reliable for varied analytical tasks.
Is the material clear enough for visual inspection?
Yes, the tubes feature a translucent finish. This high-quality, semi-rigid plastic allows for easy and clear visual inspection of your samples without compromising the structural integrity of the tube.
Does the round-bottom design affect stability?
The round-bottom silhouette is specifically engineered to fit perfectly into standard laboratory rack configurations. This ensures they remain stable and upright during your daily liquid handling and sample storage routines.
Are these tubes suitable for applications requiring sterility?
These specific tubes are non-sterile. They are intended for high-throughput testing environments where sterile conditions are not a requirement, helping to provide a more economical solution for everyday, routine laboratory tasks.
Can I use these with oxidizing acids?
No. While these tubes offer excellent resistance to a wide variety of chemicals, they are not recommended for use with oxidizing acids. Please ensure your specific chemicals are within the compatible list, which includes organic solvents, alkalis, alcohols, and ketones.
Are these tubes precision-engineered for consistent performance?
Yes. Every tube is precision-molded by Caplugs Inc., ensuring that every unit meets the same high standard of quality. This manufacturing precision minimizes variations, which is critical for consistent results in research and diagnostic workflows.
What is the physical size of these tubes?
The tubes feature a capacity of 5 mL with a standard physical profile of 12 x 75 mm. This standard sizing makes them an ideal staple for general laboratory analyses and universal sample handling workflows.
