This library is growing every month. Thanks to all the laboratories who've provided their protocols in conjunction with detailed discussions about their procedures.
Fluid transfer/enclosed tissue processors also avert particular troubles often encountered with tissue transfer/open processors including dropped tissue baskets or baskets hanging within the air and drying out. All modern-day fluid transfer/enclosed processors have fume Manage programs, and extra functions could include various retorts, retort fill and tension/vacuum amount sensors, reagent monitoring, reagent autorotation, squander administration programs, battery backup, remote checking programs in the event of malfunction, and lots of Other individuals. Currently regular fluid transfer/enclosed processors are widely Employed in higher through put pathology laboratories, Whilst selected exercise options now also use microwave-assisted tissue processing.
