6 Maintenance
Compulsory inspections and maintenance
All regulations aimed at keeping the Rotavapor in good working
order must be observed. They include cleaning the Rotavapor
at regular intervals and examining it for any signs of damage.
6.1 Cleaning and inspecting
Heating bath
Clean the bath with household detergent. If necessary, clean
the heater with anti-liming agent.
Glass components
Wash the glass components with commercial detergents (e.g.
a mild soap solution). Remove stubborn dirt (e.g. algae) from
inside the condenser coils with suitable cleaning agents
(if necessary, allow glassware to soak in the cleaning solution).
After cleaning and completely drying the glass components,
you must examine each item for signs of chipps or cracks.
The glass components of rotary evaporator are under vacuum
when in use – it is important, therefore, to carry out this visual
examination conscientiously!
Vapor duct
Follow the same procedure as for the other glass components.
Vacuum gasket KD-22
Examine the seal and replace with a new seal if signs of severe
wear are discovered.
•
You will prolong the life of the seal by rinsing it and drying
with a soft cloth. This will also prevent condenser solvent
from entering into the drive unit.
• Clean the seal and glass components regularly, especially
after bumping and foaming defervescence and working
with crystalline products.
• Do not tilt the seal when fitting or removing it. Always move
it on the glass component at the axis of rotation. Do not
damage the sealing lip.
• Do not apply grease to the seal (fine abrasion and grease
act like grinding paste).
Housing
Clean the housing with a damp cloth but no detergents.
Examine also for defects (controls, plug).
Hose connections
Examine the hose connections and replace with suitable new
hoses if you discover any signs of cracking or brittleness.
