Keep the light-sensitive workflow identifiable

Use black 15 mL polypropylene conical tubes when a light-sensitive sample workflow calls for an opaque tube body.

Actual manufacturer product view. The order unit and supplied contents are stated below.

Keep the light-sensitive workflow identifiable

The manufacturer catalog places the black tubes in the range for light-sensitive samples. HS4428 is the 15 mL conical version, not the larger black 50 mL tube and not the black microcentrifuge tube. The black body changes how a sample is viewed, so use the writing area and flat lid for clear identification rather than relying on visibility through the tube wall. No quantitative optical-blocking specification is claimed.

Match the tube to the actual rotor support

The current source gives 17 mm outer diameter, 120 mm height and a maximum RCF of 9,400 × g. Check those dimensions and the conical profile against the rotor or adapter instructions. An RCF rating is not an RPM setting, and the tube rating does not override lower limits in the centrifuge system or the procedure. Support and operating conditions must be appropriate to the selected tube.

Plan the working supply around bulk packaging

The product is sterile, disposable polypropylene with a screw cap, and the catalog specifies 500 tubes per case as 20 packs of 25. Lot-to-lot traceability and easy-tear packaging support organization of the supply. Bulk packaging is not individual wrapping, so plan opening and handling accordingly. The source lists autoclavability, but does not establish a specific sterilization cycle here. This model was supplier-out-of-stock at verification and is not represented as available stock.

Frequently Asked Questions

Is this the black 15 mL version?

Yes. HS4428 is the black 15 mL conical tube.

What is the maximum RCF?

9,400 × g. Check the rotor, adapter and procedure limits as well.

Does 9,400 × g mean 9,400 RPM?

No. Relative centrifugal force and rotational speed are different quantities.

Are the tubes individually wrapped?

No. The catalog specifies bulk packaging: 500 tubes as 20 packs of 25.

How are samples labeled?

The tube has a writing area and a flat lid for labeling.

Can I assume any 15 mL rotor accepts them?

No. Verify the 17 mm diameter, 120 mm height and conical profile against the rotor or adapter requirements.

Are they supplied sterile?

Yes. The current manufacturer listing identifies them as sterile.
