Avoid the risk of occupational infections – with the new gold standard cold disinfection in cryostats

Every year, tens of thousands of health-care workers suffer from occupational infections, such as HBV, HCV and HIV. Their risk of catching these infections is significantly higher than in the average population. Working with infectious material is inherent to work in pathology laboratories, which is why it is our goal to minimize any health hazards. With enhanced safety and efficiency in mind, the new patented cold disinfection solu-tion is being introduced as standard with the Thermo Scientific Microm HM550. Cold disinfection from Thermo Scientific offers customers instant disinfection, significantly reducing risks to the occup-ational health of laboratory staff.

Outstanding advantages• Ready for use in just three minutes

– no workflow interruption• Immediately available for use after

disinfection cycle• Utilizes Sanosil®, a powerful non-

hazardous disinfectant – complete-ly safe for lab technicians

The keys to a new gold standard• Instant disinfection of the entire

cold cryo-chamber – 100 times faster than existing methods

• Fumigation of disinfection by ultra-sound – instrument is immediately available for use, resulting in signif-icantly higher throughput

• Micro-droplets uniformly moisten the entire cryo-chamber

Sanosil® – no need to be toxic to be effective• A disinfectant and virucide that

harnesses the natural, antimicrobial powers of Hydrogen Peroxide and Silver (Ag+)

• The combination of these two elements provides pure, 99.99% disinfecting power

• Contains NO chlorine, aldehydes, phenolics, ammonium compounds, sodium hydroxide or any other harmful toxins or carcinogens

• Clear and odorless

Perfect results quickly and safely – whilst meeting the highest standards for hygiene.Ready for safe operation in just 3 minutes. Create and maintain a safe and germ-free working environment. Thermo Scientific Microm HM550 is now equipped with the new cold disinfection feature. Hygiene and cleanliness of your cryo-chamber is now assured – with no compromise. Enjoy a fully flexible system created with safety, precision and flexibility in mind.

Snap freezing via active deep freezing device• Integrated Peltier: fast freezing of the tissue at a temperature

down to -60°C• Offers four positions for chucks with a diameter up to 30 mm• The 9 position fast freezing rail provides temperature control

down to -40°C

Perfect specimen orientation• “0-positioning“ device – automatically locks the specimen

orientation into place• Fast automatic approach of the tissue towards the knife edge (ACA)

Ergonomics, safety and design• Fully adjustable electronic handwheel brake in any

specimen position• Designed to be operated while sitting or standing• Keyboard and display intuitively guide through all operations• Reflex-free chamber illumination• Large storage surfaces• Drain system with containers for waste fluids

Option: Integrated Vacutome• Stretching sections and disposal of section debris via a suction device• Suction power can be selected by the user• Pre-cooled coarse filter of the dual filter system collects section

debris and purifies the air

Option: Specimen cooling with “quick release“ mechanism• Specimen cooling is completely integrated into the microtome• Chamber volume and storage shelves are completely maintained• “Quick release” mechanism for clamping chucks allows for fast

changing of specimen

Option: Motorized cutting drive• Three different cutting modes• Double click philosophy provides protection against unintended

motion

NEWOvercoming obstacles of conventional disinfectionNo interruption of your workflow• Current disinfection after warming up the cryo-chamber takes

up to 3 hours – with cold disinfection you are ready in just 3 minutes

Complete disinfection of the entire cryo-chamber • Not all current disinfections are fully effective, for example, with

UV light only disinfects the areas reached by light – cold disinfection reaches the entire cryo-chamber

No health risks caused by the disinfectant reagent• Current disinfection, for example, by vaporization of formalin or

others, is potentially toxic – cold disinfection with Sanosil is non-toxic with proven effectivness
