Cole-Parmer Pipette Rack, 100 to 1000 µL Long Tip; 6/PK

Description

This package contains six racks of extended-length pipette tips compatible with adjustable-volume pipettes covering the 100 to 1000 µL range. The extended barrel design provides additional reach, making these tips applicable for accessing liquid samples in deep or narrow containers like centrifuge tubes, vial inserts, and certain culture tubes where standard tips may be insufficient. The tips are produced from medical-grade polypropylene, which offers clarity and is formulated for low liquid retention to support accurate dispensing. They are certified to be free of detectable RNase, DNase, DNA, and pyrogens, rendering them appropriate for sensitive applications in molecular biology, including PCR and nucleic acid analysis. A universal fit design aims to ensure a secure seal on most major brands of compatible pipettes. The tips are presented in a single, stackable rack for convenient bench-top organization and storage, facilitating efficient workflows for general laboratory procedures requiring reliable mid-volume pipetting with extended reach.
