[0032] Another object of the invention is to provide an automated biological reaction system which provides for a means of automatically downloading data relating to the reagents including serial numbers, reagent types, lot numbers, expiration dates, dispenser type, and the like in an efficient and reliable manner.
[0033] Another object of the invention is to provide an automated biological reaction system which consistently and efficiently applies a predetermined amount of buffer upon the slide to which a precise volume of reagent can be added upon the slide.
[0034] A further object of the invention is to provide a fluid dispenser, which is used in conjunction with the biological reaction apparatus, which is reliable.
[0035] Yet a further object of the invention is to provide a fluid dispenser, which is used with a wider array of chemistries in conjunction with the biological reaction apparatus, which is easy to manufacture.
[0036] Still another object of the invention is to provide a fluid dispenser, which is used in conjunction with the biological reaction apparatus, which is compact in size.
[0037] Still yet another object of the invention is to provide a fluid dispenser which is easy to prime.
Problems solved by technology
However, the computer control is limited in that it is dedicated to and resident on the biological reaction apparatus.

Embodiment Construction
[0099] The automated immunostaining system of this invention performs all steps of immunohistochemical irrespective of complexity or their order, at the time and temperature, and in the environment needed. Specially prepared slides containing a bar code identifier and a mounted tissue section are placed in special supports on a carousel, subjected to a preprogrammed sequence of reactions, and are removed from the carousel, ready for examination. For purposes of clarity of the following description of the apparatus of this invention and not by way of limitation, the apparatus will be described in terms of immunohistochemical processes.

Abstract
A method and apparatus for an automated biological reaction system is provided. In the processing of a biological reaction system, there is a need for consistently placing an amount of fluid on a slide. In order to accomplish this, several methods are used including a consistency pulse and a volume adjust means. Moreover, in order to reliably operate an automated biological reaction system, the dispenser must be reliable, easy to assemble and accurate. Among other things, in order to accomplish this, the dispense chamber is substantially in line with the reservoir chamber, the reservoir chamber piston is removed, and the flow of fluid through the dispenser is simplified. Further, in order to operate the automated biological reaction system more reliably, the system is designed in modular pieces with higher functions performed by a host device and the execution of the staining operations performed by remote devices. Also, to reliably catalog data which is used by the automated biological reaction system, data is loaded to a memory device, which in turn is used by the operator to update the operator's databases. The generation of the sequence of steps for the automated biological reaction device based on data loaded by the operator, including checks to determine the ability to complete the run, is provided.
