Hamilton Pipette Tips 300 ul Filtered Sterile for CO-RE II 60 Racks

Description

Hamilton 235903 CO-RE II Pipette Tips – 300 µl, Conductive, Filtered

The Hamilton 235903 is a premium-grade, automated pipette tip designed for high-precision liquid handling on Hamilton automated workstations. Featuring the advanced CO-RE II (Compressed O-Ring Expansion) technology, these tips offer superior tip-to-channel alignment and a robust seal that minimizes wear on the pipetting mandrels. These 300 µl tips are manufactured from conductive black polypropylene, enabling Liquid Level Detection (cLLD) for precise aspiration even in varying sample volumes. Equipped with a high-efficiency aerosol filter, the 235903 ensures maximum protection against cross-contamination, making it the ideal choice for sensitive genomics, proteomics, and clinical diagnostic applications.

Technical Performance and Design

• CO-RE II Technology: The second-generation CO-RE design features a refined seating area that ensures perfectly straight tip attachment and reduces the force required for tip ejection, extending the maintenance intervals of the liquid handling arm.

• Conductive Liquid Level Detection (cLLD): The conductive black polypropylene material allows the system to sense the liquid surface accurately, preventing “submerging” and reducing the risk of exterior tip carryover.

• Integrated Aerosol Filter: A high-purity porous barrier prevents the passage of aerosols and liquid droplets into the pipetting channel, protecting the internal components from corrosion and preventing sample-to-sample contamination.

• Precision Molding: Manufactured to the highest tolerances to ensure consistent orifice geometry, resulting in industry-leading CV (Coefficient of Variation) and accuracy at volumes as low as 10 µl.

Key Benefits & Applications

• High-Throughput Screening: Optimized for the rapid processing of deep-well plates and microplates in pharmaceutical drug discovery and compound management.

• Molecular Diagnostics: The filtered design is essential for PCR and NGS library preparation, where the prevention of DNA/RNA aerosol contamination is critical for result integrity.

• Automated Precision: Specifically designed to eliminate the common “tip drip” or misalignment issues found with generic automated tips, ensuring reliable 24/7 operation.

• System Longevity: The CO-RE II interface is gentler on the pipetting hardware compared to traditional “press-fit” tips, significantly reducing long-term repair costs.
