Reagent delivery system, dispensing device and container for a biological staining apparatus
First Claim
1. A reagent delivery system in an apparatus for processing biological samples arranged on carrier elements, the apparatus comprising a stationary reagent section having one or more reagent containers and a stationary staining section in which at least one carrier element is arranged, comprising:
- a probe for aspirating a portion of reagent from a reagent container in order to dispense a predetermined amount on a predetermined carrier element;
and a probe handling device for handling the probe, wherein the probe comprises a continuous probe tubing extending through a rigid probe member and providing fluid communication from a dispensing end of said probe member to a pneumatic pressure regulation device and wherein the rigid probe member is adapted for cooperation with the closure of the reagent container, wherein the continuous probe tubing is provided with a spirally wound probe tubing section.

Abstract
The invention concerns reagent delivery system for an apparatus for processing of biological samples arranged on microscope slides, comprising a reagent section having one or more reagent containers; a slide section in which at least one microscope slide is arranged; a probe for dispensing a portion of reagent onto a predetermined microscope slide, and means for handling the probe. The probe comprises a continuous prove tubing element extending through a rigid probe member and connecting the probe tip to a pneumatic pressure regulation device. The reagent containers are adapted for cooperation with the probe tip. In this manner a high though-put and a very low carry over of fluid residues is achieved since there is no assembled parts making up the inside volume of the probe in which the fluid may be retained.
