Fully automated sample processor PRESTO PRO

for histologydiagnosticfor slide staining

PRESTO PRO is an innovative bench top processor/stainer designed to deliver high quality results for frozen sections by providing a standardized and automated approach to processing and staining up to 6 frozen slides simultaneously. Its configuration ensures reproducible, consistent, and high quality intraoperative frozen sectioning and accommodates increased workloads. Pathologists rely heavily on the frozen section technique for intra-operative consultation when the surgeon requires a rapid diagnosis or immediate feedback regarding surgical margins. Frozen sections offer a short turnaround time (15-20 minutes) but usually have the disadvantage of lower diagnostic quality than paraffin sections due to cryoembedding artifacts and variability in staining protocols. Milestone offers a new approach to overcome these limitations by combining the artifact-free freezing process of PrestoCHILL with the superior processing and staining capabilities of PRESTO PRO. The advantage of PRESTO PRO is that it provides a standardized and reproducible process that is capable of both efficient processing and staining protocols. This results in improved morphology of the analyzed specimens and maintains a high standard of result quality. PRESTO PRO automates processing and staining by using an automated arm to move the rack, capable of holding 6 slides, to the correct vessel on a circular platform. The PRESTO PRO arm lowers and lifts the rack into and out of the vessels, starting with a heated FineFIX fixation, followed by other customizable staining steps. Automation of the process ensures standardized, reproducible, and superior quality results, regardless of operator skill.
