Tissue-Tek Xpress^® Series Processing Reagents

Reagents uniquely formulated for safe, efficient, and rapid tissue processing

Tissue-Tek Xpress Series Processing Reagents are proprietary reagents that are specially formulated for use on Tissue-Tek Xpress Series Rapid Tissue Processors, including the Tissue-Tek Xpress^® x120 and Tissue-Tek Xpress^® x50.  Tissue safety is of the utmost importance during tissue processing.  The three most common sources of errors that can lead to possible tissue damage and non-diagnostic tissue involve reagents, and these errors include creating an incorrect dilution or concentration, pouring the wrong reagent into a wrong bottle, or mixing up reagent bottle positions on a processor.  By combining the simple, ready-to-use Xpress Series Reagents with the ingenious error-free design of the Xpress Series Rapid Tissue Processors, you never have to worry about these errors again.  No dilutions, no pouring, and no bottle swaps equals a worry- and error-free system that requires users to do perform zero extra steps for safety like RFID or barcode scanning of the reagents.  Xpress Series Tissue Processing Reagents help your laboratory reduce risk and improve tissue safety without the need for non-value-added steps.

Tissue processing reagents need to do one job and do it well, and that job is to properly process tissues.  From H&E to advanced testing methods like immunohistochemistry or molecular, the Xpress Series Reagents are the key to excellent tissue quality that is equal to or better than that produced by a conventional tissue processor based on a blind comparison study¹.  With reagents compatible with all routine and advanced staining methods, Xpress Series Reagents enable your laboratory to continue to provide the high-quality, expected results that are crucial to a proper diagnosis.

Tissue processing is often the most time-consuming step in the histology process with conventional processing protocols often taking multiple hours as multiple reagents are pumped in and out of the tissue processor retort.  Xpress Series Reagents are combination reagents expertly designed for rapid tissue processing.  The liquid processing reagent in the processing kit performs dehydration and clearing of tissues simultaneously, saving time and reducing reagent volume on the processor.  Processing time for even large tissue samples can be reduced from up to 8 hours on a conventional processor to only 2.5 hours, saving up to 5.5 hours¹.  Pairing the Xpress Series Reagents on the Xpress x120 with the power of continuous automated embedding on the Tissue-Tek AutoTEC^® a120 provides the fastest achievable turnaround time, enabling laboratories to reduce the time from grossing to microtomy by an average of 10.5 hours².  Xpress Series Reagents empower your laboratory to process faster, significantly improving turnaround time and the ability to provide same-day diagnosis of more cases.

Conventional processing requires a significant volume of often hazardous reagents, resulting in large inventories, costly removal, and, of course, increased risks of exposure to you, the user.  Xpress Series Reagents are both formalin- and xylene-free.  The innovative tissue processing reagent design is capable of processing up to 1,500 cassettes from a single kit, reducing in-lab inventory, but more importantly, saving money by cutting reagent waste by up to 80%.  Xpress Series Reagents will allow your laboratory to minimize waste management costs while promoting a less hazardous working environment.

Changing reagents on a conventional tissue processor wastes valuable tech time that can be better used on other tasks.  Xpress Series Tissue Processing Reagents come ready-to-use in a single kit that includes both the liquid processing reagent as well as the properly measured amount of paraffin.  An entire change of the reagents can be accomplished in less than 15 minutes and completely error-free.  There is no need for redundant checks, extra steps, or additional rework.  No tissue processing reagent exchange is faster or easier.  Xpress Series Reagents offer your laboratory add convenience, allowing your staff time for other important duties.
