Product Information

Full details

This guide is for researchers and lab technicians using the Eisco Polypropylene Graduated Centrifuge Tube. The key benefit is its leakproof design, ensuring sample integrity during centrifugation. A minor caveat is that the polypropylene material is not compatible with all chemicals. This tube features a 50ml capacity with a conical, pointed end for efficient pelleting. It is graduated for accurate volume measurement and includes a cap with a built-in seal ring.

Is the tube leakproof?

Yes, it has a built-in seal ring for leakproof operation.

What are the dimensions of the tube?

The height is 116 mm and the outside diameter is 29mm.

Can I use this tube with any centrifuge?

Ensure your centrifuge rotor is compatible with the tube's dimensions and the g-force limitations. Always balance the tubes properly.

How do I clean the tube?

Rinse thoroughly with a compatible solvent and then wash with a mild detergent and water.

What is the pointed end for?

The pointed end aids in the efficient collection of sedimented material after centrifugation.

Troubleshooting

Tube leaks during centrifugation.

Ensure the cap is securely tightened. Check the seal ring for damage and replace the cap if needed.

Graduations are difficult to read.

Clean the tube carefully to remove any residue that may obscure the markings. Use a permanent marker to re-mark if necessary.

Tube cracks or breaks during centrifugation.

Ensure the tube is compatible with your centrifuge. Do not exceed the tube's recommended g-force. Inspect for cracks before use.

Cap becomes difficult to open.

Rinse the cap and the tube threads. If the cap is persistently difficult to open, consider using a different cap or tube.

Pros and Cons

Pros

  • Leakproof design ensures sample integrity.
  • Graduated markings enable precise measurements.
  • Durable polypropylene construction.
  • Conical shape enhances pelleting efficiency.
  • Compatible with a wide range of laboratory chemicals.
  • Easy to clean and sterilize.

Cons

  • Not compatible with all chemicals; specific compatibility should be checked.
  • Polypropylene can become brittle at extremely low temperatures.
  • Graduations may fade with repeated use and cleaning.
  • May not be suitable for high-speed centrifugation with certain rotors.

Setup, Compatibility & Care

  1. Setup: Ensure the tube is properly balanced in the centrifuge rotor before use. The tube is ready to use immediately.
  2. Compatibility: The tube is compatible with most common laboratory chemicals, but consult a chemical compatibility chart if using unknown substances. Avoid strong oxidizing agents. Check that the centrifuge rotor is compatible with the tube's dimensions.
  3. Care: Rinse the tube thoroughly after each use with a suitable solvent. The tube is autoclavable, so sterilize it to ensure no contamination. Store the tubes in a clean, dry location. Inspect the tubes for any signs of damage or degradation before each use.
