Beckman Coulter Pipette Tips AP384 P30XL 50ul Sealed Case of 3840 Tips

Beckman Coulter A22288 Biomek AP384 P30XL Pipette Tips – 50 µl (Sterile)

The Beckman Coulter A22288 P30XL is a specialized automation-grade pipette tip engineered for high-density 384-well liquid handling on Biomek FXP, NXP, and i-Series workstations. Featuring an extended, narrow profile (43 mm), these XL tips are designed to reach the bottom of deep-well microplates and specialized reservoirs without the pipette head contacting the labware. With a maximum capacity of 50 µl—offering 20 µl more volume than standard P30 tips—the A22288 provides the versatility needed for large-volume transfers, dilutions, and reagent distribution in high-throughput genomic and proteomic workflows.

Technical Performance and Design

• P30XL Extended Reach: The 43 mm narrow-bore design allows for "bottom-of-the-well" aspiration in deep-well plates, ensuring maximum sample recovery and reducing dead volume in high-value assays.

• Enhanced Volume Capacity: Provides a 50 µl working volume, significantly increasing the range for 384-head operations compared to standard 25 µl or 30 µl tips.

• Automation-Grade Precision: Manufactured from 100% premium-grade polypropylene to ensure straightness and a leak-proof seal, critical for maintaining positional accuracy across all 384 channels simultaneously.

• Certified Purity: Every lot is certified to be free of DNA, DNase/RNase, PCR inhibitors, pyrogens/endotoxins, and trace metals, protecting sensitive molecular samples from contamination.

Key Benefits & Applications

• Deep-Well Access: Perfect for Next-Generation Sequencing (NGS) and high-throughput screening where reagents are stored in deep-well blocks or 384-well V-bottom plates.

• High-Throughput Efficiency: The 384-tip format allows for the rapid processing of entire microplates in a single aspiration/dispense cycle, maximizing instrument throughput.

• Hardware Longevity: Engineered for a perfect fit on the AP384 head mandrels, requiring lower attachment forces and reducing mechanical wear on the robotic head components.

• Consistent Fluidics: The ultra-straight tip geometry ensures that every tip targets the exact center of the well, preventing "wall-touching" and ensuring uniform volume delivery across the plate.
