Abstract

A fluid handling assembly for selectively coupling and decoupling with a pipet tip can include a sampling arm, an arm cover, a probe carrier unit, a probe, and a biasing spring. The arm cover can be carried by the sampling arm. The probe carrier unit can be movably mounted within the arm cover, with the probe carrier unit including a probe release structure and a main probe carrier. The probe release structure and the main probe carrier can be interconnected. The probe can be carried by the main probe carrier and movable through a probe opening in the arm cover. The probe can be configured to releasably carry a pipet tip. The biasing spring can be carried within the arm cover and can contact the probe release structure. The biasing spring can bias the probe release structure to push the probe down toward the probe opening in the arm cover.
