Packard MultiPROBE 6000606 Automated Pipette Tips – Small, Conductive, Black The Packard MultiPROBE 6000606 (now under Revvity / PerkinElmer) is a small-volume disposable pipette tip engineered specifically for automated liquid handling workstations. Molded from premium polypropylene blended with high-purity carbon black, these conductive tips enable the robotic system's VariSpan or automated pipetting arms to execute precise Liquid Level Detection (LLD). By establishing a weak electrical circuit upon touching the fluid surface, the workstation can aspirate from a tightly controlled depth, eliminating tip immersion errors and maximizing volumetric reproducibility. Supplied in structured racks, these small-format tips are optimized for minimal dead volumes in high-density high-throughput screening applications. Technical Performance and Design Carbon-Infused Conductivity: Embedded graphite particles render the naturally insulating polypropylene conductive. This feature interfaces with capacitive or electronic liquid-sensing modules to ensure accurate surface mapping without physical submersion. Automated Workstation Fit: Specifically machined to cross-reference the exact physical seating dimensions of Packard MultiPROBE, MultiPROBE II, and legacy PerkinElmer robotic hardware, ensuring straight vertical alignments and zero-drop tip ejections. Small Volume Optimization: The ultra-fine tapered tip geometry minimizes fluid retention, drastically lowering percentage coefficient of variation (%CV) metrics during micro-volume liquid distributions. Rigid Rack Stabilization: Packaged in specialized, robust grids that hold the individual tips perfectly rigid, preventing deflection when high-downforce automated handler heads lock into place. Product Specifications Catalog Number: 6000606 Manufacturer: Packard / PerkinElmer (Revvity) Tip Classification: Small Volume Material: Carbon-Infused Polypropylene Color: Opaque Black Format: 96 Tips per Rack Liquid Level Detection (LLD): Fully Compatible (Capacitive/Electronic) Key Benefits & Applications High-Throughput Screening (HTS): An essential consumable for automated compound aliquoting, plate replications, and serial dilution sequences where walkaway reliability is required. Carryover Prevention: The disposable single-use format entirely replaces the need for fixed-needle wash cycles, bypassing the risk of sample carryover or ghost contamination in sensitive clinical assays. Cross-Contamination Mitigation: LLD functionality restricts tip immersion to just beneath the liquid meniscus, preventing fluid from coating the outer wall of the tip and tracking into downstream wells. Assay Miniaturization: The narrow orifice and small bore volume are ideal for low-volume PCR setup, enzymatic profiling, and compound storage transfers.
