Precision for Laboratory DemandsDesigned for optimal performance in research, clinical, and molecular biology laboratories, these microtubes support efficient microsample storage and high-speed centrifugation. The conical bottom enhances sample recovery, and the free-standing base ensures stability during sample processing and pipetting.
Superior Material and Leak-Proof DesignConstructed from medical-grade polypropylene, the tubes offer chemical resistance and safety at a range of extreme temperatures. The screw cap with an integral O-ring delivers a secure, leak-proof seal, making them ideal for both sample storage and transport.
Graduated Convenience and Custom PackagingFeaturing clear graduation markings at 0.5ml, 1.0ml, 1.5ml, and 2.0ml, these tubes allow for precise measurement. Available in convenient bag packs of 500 or custom sizes to suit varying laboratory requirements.
FAQs of Free-Standing 2.0ml Screw Cap Microtubes with Conical Bottom:
Q: How should these microtubes be sterilized for laboratory use?
A: These microtubes are supplied non-sterile but can be sterilized by autoclaving at 121C. Ensure the caps are loosened during autoclaving to avoid pressure buildup, and allow the tubes to cool before handling.
Q: What is the maximum centrifugal force these tubes can withstand and for which applications are they suitable?
A: The tubes can tolerate a maximum relative centrifugal force (RCF) of 20,000 x g, making them suitable for molecular biology protocols, clinical sample processing, and research applications that require high-speed centrifugation.
Q: When should I use these free-standing microtubes over other tubes?
A: These free-standing microtubes are ideal when you require stability on the bench. They are especially useful during sample loading, incubation, and centrifugation, reducing the risk of sample spills.
Q: Where can I purchase these microtubes and are custom pack sizes available?
A: The microtubes are available through various suppliers, exporters, and manufacturers in India. You can order standard packs of 500 or request custom pack sizes based on your laboratorys needs.
Q: What benefits does the smooth, low-binding surface provide for sample handling?
A: The smooth, low-binding polypropylene surface minimizes sample adhesion, ensuring maximum sample recovery and accuracy, which is particularly important when working with precious or small-volume samples.
Q: How are the volume levels indicated on the microtubes?
A: Each tube features graduation markings at 0.5ml, 1.0ml, 1.5ml, and 2.0ml, allowing for quick and precise volume determination during experimental procedures.
Q: What makes the leak-proof feature valuable for laboratory workflows?
A: The integral seal with O-ring and robust screw cap ensures no leakage, safeguarding your samples during storage, mixing, or centrifugation, and enhancing workflow reliability.
