The cryostat HM 520 / HM 525 combines a maximum of user benefit with the highest operator comfort. Again, we dedicated our special attention to the operator comfort of this Microm cryostat resulting in ergonomically shaped surfaces and intuitively comprehensible operating elements. The introduction of the stepping motor technique into this instrument class now allows reproducibility as well as excellent sectioning results also in the histological/pathological
routine. The below-mentioned features of the HM 520 / HM 525 will
guarantee the fast and uncomplicated creation of sections also in
your lab.
Stepping motor technique for lasting reproducible section thicknesses
The reproducibility of the section thickness is a principal domain of the HM 520 / HM 525 and cannot be achieved without stepping motors.
The use of stepping motors in this market segment sets new standards concerning operator safety. Section thicknesses are set outside the chamber via the keyboard without having to reach into the potentially infectious cryo chamber over the knife.
In addition, this technology allows the indication of the number of sections, the section thickness sum and the remaining sectioning travel on the display.
Highest operator comfort and user benefit
To gain an optimum of operator comfort and user benefit for the HM 520 / HM 525 has been our utmost goal.
Fast freezing device with max. 27 positions
Due to the large number of fast freezing stations up to 27 pieces of tissue can simultaneously be frozen very fast. If there is a very a high amount of specimens to be processed, the time-consuming freezing of the specimens „one after the other“ can be avoided. HM 525 with 4 Peltier supported stations, up to -60°C for even faster freezing.
Memory function
With the memory function it is possible for the operator to automatically approach the specimen towards the knife. This process can be programmed and the fi rst cut position can be found again rapidly.
Keyboard and operation
Most simple operation of the instrument due to logically arranged, easy-to-clean keyboard and display for the indication of relevant data. Self-explanatory setting of all instrument functions.
Specimen orientation with "zero" positioning
In the zero position, the specimen orientation automatically locks into place. The surface of the chuck is aligned parallel in x- and y-axes towards the horizontal specimen stroke.
This easy and uncomplicated specimen orientation allows the fast orientation of the specimen in relation to the knife.
Ergonomics and design
The ergonomic design allows for a non-tiring and fast operation both while sitting or standing. The front area of the cryostat hood has a recessed surface for
labelled slides that can be put down here in a row. A recessed storage surface on top of the cryostat hood offers a safe and space-saving positioning of staining kits.
Operator safety and cleaning
Operator safety and easy cleaning have been very important features when designing the cryostat. The handwheel brake is integrated into the handwheel. The spacious cryo chamber is made of stainless steel that can easily be cleaned. The microtome is protected against debris via close-fi tting stainless steel plates.
Large brush shelf and divided section waste tray
All necessary tools such as brushes, tweezers etc. can be stored in the large brush shelf. The divided, easily removable section waste tray is integrated below the blade carrier and/or specimen.
Drain system with spacious container
The cleaning and disinfection liquids of the cryostat as well as the defrost water are collected in the easily removable, spacious container.
Disposable blade carrier EC 70
With this new blade carrier for disposable blades, larger specimen sizes can be sectioned. This is supported by the special coating of the anti-roll plate. It has an anti-static coating on its bottom side and an anti-refl ecting coating on its upper side. The anti-static coating supports the gliding of sections underneath the plate. The anti-refl ecting coating allows the evaluation of the section when it is
created underneath the plate. The length of the glass anti roll plate is 70 mm.
Handle for transportation or movement purposes
The retractable handle is integrated in the front area of the cryostat.
Via this handle, the instrument can easily be transported on its smooth running rollers.
