A completely new concept for needle wash has been designed for Integrity. A separate built-in solvent pump provides wash solvents to the needle pair and a smart combination of air pressure and solvent streams ensures thorough cleaning of the needle pair, inside and outside, in seconds. And also provided – jet-stream drying of the needles before entering the next sample! Multiple solvents can be selected by the wash pump for maximum clean-up ensuring zero carryover for the stickiest samples. Because the wash pump is much faster than the syringe-dispenser used for the injection, needle rinsing is not only better, but also much faster.
