Verifying dispensing performance & optimizing accuracy on a Redd&Whyte Preddator nano-bulk reagent dispenser using the Artel MVS®

Nano Bulk Reagent dispenser DropletsThis application note discusses an approach to verify and optimize the dispensing accuracy on a Redd & Whyte Preddator1 dispenser using measurement information from the Artel MVS®. The Preddator is able to dispense any number of liquid types and the MVS supports verifying both tip-to-tip precision and accuracy values for nearly all liquid handlers.2,3 The focus of this application note is on volume verification and subsequent optimization; it does not speak to the quality of volume transfer performance you should expect from any Preddator. Pipetting accuracy can be improved in multiple ways on the Preddator, such as by adjusting

Redd&Whyte Preddator Low-volume Dispenser for DMSO Back-filling used by Leading Biopharmaceutical Company Application Increases Throughput by a Third and Improves Assay Accuracy

Redd&Whyte, an expert supplier of liquid handling automation for drug discovery and life science research applications, today announced its Preddator system has been integrated in an assay workcell by AstraZeneca, to meet a generic high throughput nano-litre dispensing application. Using the Preddator system, the assay run time has been significantly reduced, while maintaining the dispensing consistency and flexibility of the original workcell.

Low volume dispensersScientists in the Oncology Group at AstraZeneca (Alderley Park, UK) integrated the Preddator system as an additional dispensing module to complement a Labcyte ECHO 555 acoustic reformatter in a high throughput cell-based screening workcell. The system is routinely …

New Software Update: flying reagent dispenser and new valve calibration

The Preddator S4’s software has recently been updated with on-the-fly dispensing functions. The Preddator’s high precision solenoid dispensing valves allow for faster dispensing to any rectangular shaped region. This update allows 500nl to be dispensed to an entire 384-well plate in 9 seconds, and 200nl can be dispensed to a 1,536-well plate in just 26 seconds.

Flying Reagent dispenser

In addition, the valve calibration procedure has also been enhanced to allow calibration profiles for each valve, resulting in improved dispensing performance. A single calibration at a designated “master” volume allows the calibration to be checked frequently, and can easily be updated if necessary, …

Introducing the New Preddator Rinse Station

Redd&Whyte have developed a rinsing station for their popular Preddator S4 which now has expert rinse and cleaning capabilities.

The new and improved rinse station allows the Preddator’s high precision dispensing valves to be cleaned at a rapid speed using a rinse solution, and an air-blade to dry the valves, before or after dispensing.

This is ideal when dispensing reagents that are prone to precipitating, such as buffers, or any other sample media that could cause clogging. As a result, the dispensing performance is maintained each time a plate is run.

The rinse station consists of a trough with 4 …
