Nexar inline liquid handling system
Nexar™is a modular Inline Liquid Handling and Assay
Processing System offering a highly scalable solution for PCR-based genotyping.
Pipette Dispensing
The Dispense Pipette features a CyBio head with 384 or 96 tips. It aspirates the samples from the sources plate and stamps them in the Array Tape. The dispense jet aspirates the reagent from the source plate and adds it to the samples on the fly. Aspirate and dispense volumes, along with CVs, are determined by the type and style of pipette and tip tray used.

CyBio Dispense Pipette and Wash Station
Customizable Rapid Dispense Pipette
The Dispense Pipette contains an integrated CyBio Light Pipetting Head. It can be customized with a 96 or 384 tip tray. Aspirate and dispense volumes, along with CVs, are determined by the type and style of pipettor and tip tray used. Typically, a large volume of sample is aspirated and a smaller volume is dispensed simultaneously into each well in the array. The Dispense Pipette Attachment also contains a 1D/2D barcode reader that can read the 2D code on the Array Tape and the 1D (linear) code on the end of the source plate.
Parallel channel pipetting from plates using the CyBio LDH head provides rapid sample and reagent dispense into Array Tape using 96- or 384-tips in either full or quadrant stamping in a range of 600 nL to 800 nL.

CyBio Dispense Pipette Wash Stations
Biosearch Technologies offers two dispense pipette washing options to meet tip-cleaning needs and minimize plastic waste.
Pipette Wash
The Pipette Wash defends against cross-contamination while minimizing contaminant carryover between plates. During normal analytical runs, the wash procedure is automatically controlled by the Nexar’s built-in software and/or protocols.
Sonic Wash
The Sonic Wash provides ultrasonic washing of pipette tips to clean residual samples from nozzles and pipette tips. Water is plumbed into the tub and overflows the edges into a collection trough to be pumped out of the instrument. Ultrasonic cleaning is provided by a transducer mounted under the tub while water in the tub is aspirated and flushed out multiple times to remove residual sample.
