50 mL Centrifuge Tube Product Description

The 50 mL centrifuge tube is a high-quality, conical-bottom laboratory container designed for efficient sample preparation, mixing, separation, and storage. Manufactured from durable, high-clarity polypropylene, it provides excellent chemical resistance and withstands high centrifugal forces. The tube features clear volume graduations for precise measurement, a leak-proof screw cap for secure sealing, and a smooth interior surface to minimize sample retention. It is suitable for a wide range of applications including biology, chemistry, clinical testing, and industrial research.

These tubes are commonly used for centrifugation of biological samples, pellet collection, reagent preparation, and long-term sample preservation. They are available sterile or non-sterile, RNase/DNase-free, and can be autoclaved depending on the model.

FAQs 50 mL Centrifuge Tube

1. What material is the 50 mL centrifuge tube made of?

Most 50 mL centrifuge tubes are made of high-grade polypropylene (PP), which is chemical-resistant, durable, and transparent for easy sample observation.

2. Are the tubes sterile?

They can be purchased either sterile or non-sterile. Sterile tubes are typically gamma-irradiated or EO-sterilized and come individually wrapped or in sterile racks.

3. Can the tubes be autoclaved?

Yes, polypropylene tubes are usually autoclavable at 121C, unless the manufacturer specifies otherwise. Always check the product label before autoclaving.

4. Are the tubes compatible with all centrifuges?

They are compatible with most standard rotor types designed for 50 mL conical tubes. Always verify rotor size and maximum rated speed.

5. What is the maximum centrifugation speed (RCF)?

Typical 50 mL PP centrifuge tubes can withstand around 9,40012,000 g, depending on brand and model.

6. Do these tubes have graduation marks?

Yes, they feature clear, molded graduation marks (usually every 2.5 mL or 5 mL) for accurate measurement.

7. Are the caps leak-proof?

The screw caps are designed to be leak-resistant when properly tightened. Many models include an O-ring for added security.

8. Can I use these tubes for freezing samples?

They can be used for short-term freezing at 80C, but they are not designed for liquid nitrogen storage unless specified by the manufacturer.

9. Are the tubes RNase/DNase-free?

Sterile tubes usually are RNase-, DNase-, and pyrogen-free. Non-sterile tubes may not be.

10. What applications are 50 mL centrifuge tubes used for?

Common applications include:

• Sample centrifugation and pellet collection

• Cell culture and harvesting

• Reagent mixing and preparation

• Sample storage

• Molecular biology and biochemistry workflows
