Kingfisher Flex Consumables

What Are KingFisher Flex Consumables?

KingFisher Flex consumables are specialized plates, tip combs, and accessories designed specifically for Thermo Scientific KingFisher magnetic particle processors, including the KingFisher Flex, Apex, Duo Prime, and Presto systems. These consumables are engineered to support automated magnetic bead-based purification workflows for DNA extraction, RNA isolation, protein purification, cell isolation, and other molecular biology applications. Their precise dimensions and well geometries ensure accurate magnetic rod movement, efficient bead transfer, and consistent purification results across high-throughput laboratory workflows.

Unlike standard deep well plates, KingFisher consumables are manufactured from low-binding polypropylene to minimize the loss of nucleic acids and proteins during extraction and washing steps. This helps maximize sample recovery, improve purity, and maintain reproducibility in research, clinical diagnostics, biobanking, and next-generation sequencing (NGS) applications.

How to Choose KingFisher Flex Consumables

Instrument Configuration

Consumable selection depends on the instrument model and processing head installed. Most KingFisher Flex systems use a 96-well head designed for medium-throughput sample processing, while certain applications require a 24-well head for larger sample volumes. Always verify your instrument configuration before ordering consumables.

Sample Volume Requirements

The 96-well format is ideal for routine DNA and RNA extraction from blood, plasma, swabs, tissue lysates, and cultured cells. Applications requiring larger input volumes, such as circulating cell-free DNA isolation, environmental testing, or stool sample processing, often use the 24-well format, which accommodates significantly larger volumes per well.

Sterility Requirements

Non-sterile consumables are commonly used for standard nucleic acid purification and protein extraction workflows. Sterile plates and sterile plate-tip comb combination packs are recommended for cell-based applications, sensitive RNA workflows, and any procedure requiring aseptic processing conditions.

Individual Components vs. Combination Packs

Many laboratories purchase plates and tip combs separately to match workflow requirements. Combination packs containing both sterile plates and matching sterile tip combs simplify inventory management and ensure compatibility between components.

Downstream Application

For PCR, qPCR, sequencing, and library preparation workflows, purified samples are typically transferred into 96-well microplates with smaller working volumes. Applications requiring larger elution volumes may use deep well plates for the final collection step.

Common KingFisher Flex Consumable Formats

KingFisher workflows commonly use 96-well deep well plates for routine magnetic bead extraction, paired with matching 96-tip combs that facilitate bead capture and transfer throughout the purification process. Larger-volume workflows utilize 24-well deep well plates and corresponding tip combs. Additional accessories include elution plates, storage plates, and sterile combination packs that streamline automated extraction workflows.

Specifications Context

KingFisher consumables are manufactured from high-purity, low-binding polypropylene to reduce non-specific adsorption of DNA, RNA, proteins, and magnetic beads. They are produced under strict quality control standards to ensure dimensional consistency and compatibility with automated magnetic particle processors.

These consumables are widely used in molecular diagnostics, genomics, biobanking, pharmaceutical research, and clinical laboratories. Their standardized design supports reproducible extraction performance while maintaining compatibility with automated sample preparation workflows.

For laboratories requiring more general automation-compatible sample processing plates, deep well plates provide SBS-format compatibility with liquid handling systems from Hamilton, Tecan, Beckman Coulter, and other automation platforms. Immunoassay and ELISA workflows, however, require specialized assay plates designed for optical detection rather than magnetic bead processing.
