A regular and/or immediate disinfection of the blade carrier, the cryo
chamber as well as all the other potentially contaminated parts of the
instrument is highly recommended. All commercially available cryostat
disinfection solutions can be used.
• Open the cleaning opening via the attached tool (fig. 134.1).
• For this, insert the tool (fig. 133.1) through one of the middle ven-

• Turn the tool by 90° so that the t-shaped holder latches into the
adjacent slots.
• Pull the tool to open the grid (fig. 133.1) of the cleaning hole.
