A new video has been added to the site highlighting Preddator’s ability to achieve high levels of precision both for the volume aliquoted and for positional accuracy.
In this application the end user wished to be able to accurately over spot aliquots of solution onto Drosophila cells contained in 384 well plates.

Redd&Whyte’s Preddator recently underwent rigorous microplate dispensing accuracy and performance checks with the NIST-approved Artel Calibration system.
The Preddator achieved impressive results for its accuracy and precision, including extremely low coefficients of variation (CV) for all channels.
Can your dispenser beat 0.69% CVs at 500 nl, across 384-well plates?

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.
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, …
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 …
