Complete Product Description

The Microm Cryo-Star HM 560 Cryostat offers fast freezing with electronic temperature control down to -35°C. With peltier refrigeration, a temperature -55°C can be achieved in this spacious, easy-to-clean cooling chamber.

Microm Cryo-Star HM 560 Cryostat Unique Double Cooling

It is not uncommon for modern cryostats to feature double refrigeration, one for the cooling block and another for the cooling chamber. The Microm Cryo-Star HM 560 optimizes refrigeration by incorporating a unique refrigeration system into the HM 560 cryostat. The specimen and knife, and not the chamber, have independent refrigeration systems and may be set as low as -50°C and -35°C, respectively. Moreover, the peltier cooling, which is integrated into the knife, allows easily programmable temperature setting for sectioning. Knife temperature can be increased and decreased more rapidly than the temperature of the chamber in other models. This feature is very important when you cut different types of tissues, each requiring a specific temperature. Also, if the tissue block was fixed before freezing, the fixative may influence the optimal cutting temperature too. The low temperature is also maintained in the chamber and is equal to the temperature of the knife.

The automatic micro/macro feed system is outside the freezing chamber and guarantees the highest precision and flexibility: From 0.5 to 500 um. The precision is the same, should you use the Fine or Trim sectioning mode, but the range of thickness is different: from 0.5 to 100 um and from 5 to 500 um, respectively. The expanded thickness range and horizontal feed of 40.000 um makes many applications possible.

The design of the cryostat is ergonomic. There is a large, reclining electronic display with buttons for each function and a cooling chamber with a removable container which permits simplified cleaning and disinfection. The absence of any screw in the chamber is noteworthy as this leaves room for the innovative magnetic knife and object holders.

Other features include the presence of the freezing/detaching device, which is equipped with Peltier cooling which resolves the problem of the often-difficult detachment of tissue blocks from the metal support used to fix the object on the holder. The temperature is quickly reversible, and you can pass from object cooling to object detaching in seconds. You only have to put the support with the block onto the plate, push the button “Detach” and let the temperature of the device attain 6°C (it takes generally only several seconds). Another great feature of the Microm Cryo-Star HM 560 is the automatic approach system (ACA). Based on the electrical resistance, this function advances the knife to the point where the object is nearly touched. It really saves time.
