Tip Combs

Cotaus provides various formats of tip combs and deep well plates made of pure polypropylene compatible with KingFisher systems and other automation platforms. These tip combs and deep well plates are perfect for magnetic particle processing, through the up and down movement of the tip comb, the sample is mixed, cracked, bound, washed, and eluted in the corresponding magnetic bead method reagents, thanks to their low binding affinity for biomolecules, ensuring excellent recovery of magnetic beads. They are ideal for high-throughput workflows in DNA/RNA extraction, NGS, and other molecular biology applications for efficient liquid handling and sample extraction.
