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

Douglas Scientific offers a pair of dispense pipette washing options to meet sample cleansing needs.

Pipette Wash

Nexar® Pipette Wash

The Pipette Wash provides your first defense against cross-contamination while minimizing contaminant carryover between plates. When the wash procedure is used at the start and end of your daily analytical runs, the Pipette Wash provides a high degree of certainty that other air-borne contaminants are eliminated. During normal analytical runs, the wash procedure is automatically controlled by the Nexar’s built-in software and/or protocols.

Sonic Wash

Nexar® 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.
