    • Designed for mid- to high-volume plasma protein throughput
    • Broad menu from one source; more than 70 assay protocols available for determination of various sample types
    • Up to 100 samples onboard
    • Antigen-excess security for confidence in results
    • Connectivity options to Aptio® Automation and FlexLab Automation solutions
    • Assistance with clinical interpretation through our innovative range of assessment programs available for Protis® IT Solution1

    Features & Benefits

    As the first dedicated protein analyzer that can be connected to lab automation, the BN™ II System provides flexible options to meet the needs of the mid- to high-volume plasma protein lab. It uses nephelometric technology for protein determination and supports the clinical management of a variety of disease states, such as gammopathies, kidney diseases, neurology, and chronic alcohol abuse.

    Increased workflow efficiency:

    • Fully automated assay processing: from reading of sample tube bar codes to reporting of results
    • Average throughput up to 130 tests per hour2, and its high onboard capacity of up to 100 samples and 35 reagents provides a walkaway time of more than 2 hours
    • Wide measuring ranges enable fewer repeats
    • User-friendly software facilitates easy operation
    • Bidirectional host interface for convenient transfer of assay requests and results to the laboratory information system (LIS)

    Flexible, efficient operation

    • Continuous loading and reloading of samples and/or reagents without interrupting the system’s current workload
    • Random-access processing eliminates sample batching
    • Accommodates standard sample tubes as well as micro cups for low-volume samples, such as samples from pediatric patients

    Confident, consistent results

    • Confidence in results when analyzing samples with extremely high analytical concentrations
    • Optimized reaction conditions and assay-specific, automated pre-reaction protocols ensure valid results without operator intervention
    • Specimen level detection and positive barcode identification for samples, reagents, standards and controls to reduce human error

    Improved workflow efficiency through automation

    • Ability to connect to Aptio® Automation and FlexLab Automation solutions
    • Interface module transfers sample tubes from the track into the BN II racks and pushes the racks onboard the analyzer
    • Reduces manual interaction
    • Extends walkaway capability
    • Continuous access to reagents and consumables
    • Enables manual loading of specialty samples, when needed

    Innovative assay menu

    • Broad menu available from one source; over 70 assay protocols for management of various clinical indications
    • Routine and specialty assay consolidation
    • Innovative markers including monoclonal kappa and lambda free light chains (FLC), cystatin C, beta-trace protein (BTP), and carbohydrate-deficient transferrin (CDT)

    Enhanced result reporting with PROTIS IT Solution

    • PROTIS® Assessment Software1 assists with interpretation support for a wide range of clinical indications
    • PROTIS IT Solution data-management software manages online data transfer between the BN II System and LIS
    • All data at a glance including graphical presentation of results, calculation of specific algorithms, and result interpretation suggestions modifiable by the user
