摘要： Means for reducing intersample contamination in an automatic chemical testing apparatus, in which liquid from a sample is aspirated from a sample source into a reservoir, and aliquots of the sample are each dispensed into individual reaction containers for analysis by well-known means. A cylindrical reservoir is utilized with a piston therein shaped for pushing out virtually all of the remaining sample from the cylinder after dispensing the sample liquid through a hollow needle, communicating with the cylinder. A solid pin coaxially mounted within the piston is projected through the needle and has minimum clearance therewith, for pushing remaining sample out of the needle. The portion of the pin projecting through the needle is retracted into the piston prior to aspiration of liquid from a next sample.

摘要： Methods and apparatus useful in automated performance of immunoassays, in some preferred embodiments, relying upon the sandwich immunoassay technique, are described. Each rack of reaction tubes is uniquely identified by an optical identifier disc which is read by the automatic controller. The assays are performed at two stations which configuration thereby permits arrays to be run on a second rack of reaction tubes while the first rack is in process. The cooperation of the identifier disc and the automatic controller minimizes operator error and helps improve the reliability of the data obtained.

摘要： Apparatus are provided which automatically add diluent/quench reagent in such a manner as to enable adequate mixing as well as a short period for further mixing in automated immunoassay techniques. The probes for adding the diluent/quench reagents are offset from the optics module probe so that reagents are being added to a second row while the optics probe aspirates solutions from a first row.

摘要： Apparatus and method for adding liquid to, aspirating liquid from, a rack of reaction tubes wherein a rack and carriage-dependent probes are made to move relative each other in the horizontal and vertical planes. The method calls for performing the first half of a wash sequence on tube located at x row, y column, then completing the sequence on tube at (x-1) row, y column, and returning to the tube at x row, (y+1) column to initiate the first half of the sequence. This "backtracking" of probes permits an incubation-soak period without cumulatively extending the total rack processing time.
摘要翻译：用于将液体添加到吸液器的装置和方法，其中反应管的架架使得齿条和滑架相关的探针在水平和垂直平面中彼此相对移动。该方法要求在位于x行y列的管上执行洗涤序列的前半部分，然后在（x-1）行y列处完成管上的序列，并返回到x行的管（y +1）列以启动序列的前半部分。探针的“回溯”允许孵育 - 浸泡时间，而不会累积延长总架处理时间。
