BNX 1536   Liquid Handling System

  • Combined dispenser and washer
  • Four independent dispense channels
  • Low dead volume
  • Fast! Dispenses 384 wells in 8 seconds, 1536 wells in 15 seconds
  • Small footprint, self-contained

The BNX 1536 liquid handling system provides both precise dispensing and thorough microplate washing in a single instrument. The small footprint houses a built-in vacuum and air pressure pump; no external vacuum pumps are needed. Each of the four reservoir bottles has its own fluid path to individual dispense heads, allowing four different fluids to be dispensed into a single microplate. A single aspiration head allows fast and efficient liquid removal from microplate wells for plate washing applications. The intuitive software provides a high degree of control over operating parameters, allowing rapid processing of robust assays and gentle processing of cell based assays. The system is robot compatible, with a robot-friendly plate carriage and accessible RS-232 COM port.

Flexible Software

With its Windows® compatible, drag-and-drop software, the BNX 1536 provides a high degree of control over process parameters. Column selection offers the choice of dispensing only a few columns, or a complete plate. For optimal dispense accuracy, the software allows fine tuning the dispense volume using the Liquid Factor tool. Dispense pressure can be lowered for a gentler dispense when using loosely adherent cells or weakly bound antibodies. Aspiration controls allow the probe height, probe offset, aspiration rate and aspiration time to be set for lowest residual volume or gentlest processing.
