Thermo Fisher Scientific Inc., the world
leader in serving science, today announced that its new Thermo Scientific STP
420
ES Tissue Processor for high-throughput tissue processing has been
independently validated for xylene-free protocols. Scientists at the Newcastle
upon Tyne Hospitals NHS Foundation Trust confirmed the successful application
of a standard xylene-free protocol on the STP 420
ES. The tissue
processor delivered quality results using existing protocols, with the
exception of the requirement for a lower temperature of 65°C, not 85°C, for the
initial wax step.
Elimination
of xylene from tissue processing can cut costs, save time and improve the
laboratory environment. Using isopropyl alcohol (IPA) as an alternative wax
miscible dehydrant removes the risks of cumulative exposure and the high
disposal costs associated with xylene, which is a hazardous chemical. Using IPA
also shortens cycle times and enables leaner workflows so laboratories can
deliver patient results faster. The Royal Victoria Infirmary, Newcastle
Hospitals, laboratory is a new ultramodern pathology facility, four times the
size of a standard UK hospital laboratory, and it is adhering to lean
principles by using xylene-free protocols.
"We see lean processing as being the most
efficient means of delivering reduced turnaround times for patient results, and
xylene-free tissue processing is a key contributor to achieving this,"
explained Jim Smith, Chief Biomedical Scientist, Royal Victoria Infirmary. "In
our evaluation of the Thermo Scientific STP 420
ES tissue processor using
our current xylene-free protocols it performed very well, delivering excellent
quality resulting preparations, whilst maintaining the validity of all
subsequent immunohistochemistry results."
The new STP 420
ES tissue processor
also meets Royal Victoria Infirmary's lean requirements since it enables faster
turnaround times for same-day diagnosis and leaner workflows through
operational flexibility. Its dual chamber design features unique rotational
agitation that increases flow of traditional reagents by seven-fold to reduce
processing times. "Having the second chamber in effect gives two processors for
the price of one, as workflow need not be stopped in the main chamber if a STAT
or difficult tissue sample is required," added Jim Smith.
