Frequently Asked Questions

Are these 50 mL serological pipettes individually wrapped or bulk packed?

These are bulk packed: 25 pipettes per bag with 4 bags per case, totaling 100 pipettes. Bulk packaging reduces per-unit cost for high-throughput labs while maintaining sterility within each sealed bag.

What does the black band on the pipette indicate?

The black color band is a quick-reference volume code that lets users identify the 50 mL size at a glance on a crowded bench, reducing pick errors during fast-paced liquid handling.

Are these pipettes compatible with standard pipette controllers?

Yes. The cotton-plugged top fits standard motorized and bulb-style pipette controllers, and the 345 mm length reaches the bottom of deep media bottles and large culture vessels.

How is sterility maintained with bulk bag packaging?

Each bag is sealed and sterilized as a unit. Sterility is preserved for pipettes remaining inside an unopened or resealed bag; once a bag is opened, contents should be used within standard aseptic-handling timeframes.
