BN II System

BN II System connectivity to Aptio® Automation video

The BN™ II System is an easy-to-use, reliable nephelometric analyzer that offers a broad range of protein assays. With assays available across multiple sample types, you can conveniently assess numerous disease states such as gammopathies, kidney diseases, neurology, and chronic alcohol abuse—on just one system.

  • Designed for mid- to high-volume plasma protein throughput
  • Broad menu from one source; more than 60 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® Data Management System1

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 60 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 System

  • PROTIS® Assessment Software1 assists with interpretation support for a wide range of clinical indications
  • PROTIS System 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
