LYNX II Automated Tissue Processor for Histology and Microscopy


EMS is proud to feature the most unique, state-of-the-art tissue processor which is compatible with all plastic resins, as well as paraffin waxes.


Introduction


LYNX II is designed to be the successor of Lynx Tissue Processor with several enhancements including capabilities to perform optional processing of larger size samples for Histology.


The LYNX II holds 12 reagent vials for EM processing. Optional HP (Histology processing) may be done with 12 larger size reagent vials for HP processing. In both EM and HP modes, LYNX II has two, independently controlled, heating/cooling stations.


Operational Overview of LYNX II


LYNX II is a batch mode, tissue processing system. The tissues may be processed for EM or HP. Tissues of either type are processed in the same manner: Samples are mounted on the sample arm and reagents are loaded on the reagent carousel. Based on the selected program by the user, the LYNX II rotates the reagent carousel until the selected reagent station is at the processing station. At the processing station the sample is lowered in the reagent. Based on the selection of agitation and vacuum, the LYNX II periodically moves the sample arm to provide agitation and applies vacuum when the agitation is not in progress. Once the programmed time in a given reagent is over, the sample is raised and the next reagent is rotated in the processing station.


The operator may select the processing for EM or HP by the program numbers. Programs 1 through 10 are used for EM processing and programs 11-20 are used for HP processing. In addition to the proper program number selection, it is the responsibility of the end user to use the proper carousel positions and the appropriate type of reagent vials based on the selection of EM vs. HP processing. Once the unit is properly configured for EM or HP processing, the operator loads the reagent carousel and the samples, selects the desired program and starts the run.


At the end of the run, the sample is retained in the last reagent until the operator removes the sample.

Functional Specifications System Configuration


1. LYNX II is designed with the following functional modules.


• Rotary mechanism to rotate the reagents • EM and HP reagent carousel


• Up/Down mechanism to move the sample in and out of the reagent as well as to provide the agitation


• EM and HP Sample arms


• Tight seal for all reagent containers except for the one at the processing station.


• Vacuum pump and a pressure sensor or a switch


• Two Peltier operated heating/cooling station with independent temperature sensors and controls


• Fume extraction fan and air flow sensor 2. Reagent Carousel


A reagent carousel may be installed, either a 12-position carousel for holding EM reagents or a 12-position carousel for holding HP reagents. The EM carousel holds cylindrical vials that are approx. 1.2" in diameter and


2.5" tall whereas HP vials are approx. 2.2" diameter (to hold 1.75" x 1.2" cassette flat) and 2.5" tall. The carousel is approx. 12" in diameter. Each vial has a flange for ease of handling. The vials are available in either plastic or aluminum. The vials may be mixed and matched between the metal and the plastic vials on a given carousel for certain kinds of processing.


The LYNX II has a built in sensor to detect that the proper reagent vial types (EM vs. HP) are installed on the unit before starting a run. Ability to detect only one of the two vial types is sufficient.


3. Sample Arm


The sample arm holds either an EM sample holder assembly or an HP sample holder assembly. Each sample holder assembly is designed to mount on the arm at a location to center the samples in its respective reagent container. The Sample Arm top may be changed to


accommodate different samples.
