Abstract
Leakage from the manifold of a manifold type multi-channel dispenser, aspirator, or washer may be diminished by employing siphon shaped pipettes and backsipping liquid from the long leg of such siphon shaped pipettes after each use of the device. The siphon shaped pipettes may be attached to the top-most part of the manifold so as to facilitate the purging of bubbles therefrom.
