MAINTENANCE 

5.1

 

Maintenace and Cleaning 

General Care: 
Maintenance of the centrifuge is dependent on prolonging the life of the rotor, the rotor chamber and 

the rotor accessories. Please be sure to clean the accessories, especially the sealing of the aerosol-

tight rotors and insert bolts, of swing out rotors.  Following, lubricate the bolts or sealing, with the 

recommended HERMLE Rotorgrease - Order No.: 38-5656.  
Please pay special attention to anodized aluminum parts. Breakage of rotors can be caused by the 
slightest damages. 
 
In case of rotors, buckets or tube racks becoming in touch with corrosive substances, the affected 

area must be cleaned, thoroughly. 
 
Corrosive substances, such as, must be avoided: alkalis, alkaline soap solutions, alkaline amines, 
concentrated  acids,  solutions  containing  heavy  metals,  water-free  chlorinated  solvents,  saline 

solutions, e.g. salt water, phenol, halogenated hydrocarbons.  

 

Cleaning Units, Rotors, Accessories: 
-

 

Turn  the  device  off  and  disconnect  from  the power  supply,  before  beginning  any  cleaning  or 
disinfecting. Do not pour liquids into the housing interior. 

-

 

Spray disinfectant on the device. 

-

 

Thorough  cleaning  not  only  has  its  purpose  in  hygiene,  but  also  in  avoiding  pollution  based 
corrosion. 

-

 

In order to avoid damaging anodized parts, such as rotors, reduction plates etc.; only pH-neutral 

Detergents, with a pH-value of 6-8, may be used for cleaning. Alkaline cleaning agents  must 

not be used, (pH-value > 8). 

-

 

After cleaning, please ensure all parts are dried thoroughly, either by hand or in a hot-air cabinet 
(Max. Tempe 50°C/122°F). 

-

 

It  is  necessary  to  coat  anodized  aluminium  parts  with  anti-corrosion  oil  regularly,  in  order  to 

increase their life-span and reduce corrosion predisposition. 

-

 

Due to humidity or not hermetically sealed samples, condensation may  form. The condensation 

has to be removed from the rotor chamber, with a soft cloth regularly 

 

 The maintenance procedure has to be repeated every 10 to 15 runs, but at least once a week! 
-

 

Connect the unit to the power supply only after the equipment is completely dry. 

-

 

Do not implement disinfection with UV-, beta- and gamma-rays or other high energy radiation. 

-

 

Metal rotors can be autoclaved. 

-

 

Rotor lid can also be autoclaved, (Max. 121°C/250°F, 20 min). 

-

 

The tube racks are made of PP and cannot be autoclaved, at 134°C/273°F.
