Maintenance
You must observe all instructions, aimed at keeping the
Rotavapor functional. This includes periodically cleaning and
checking for damages.
Before carrying out maintenance work on the apparatus, make
sure that vapour supply and current supply have been turned
off. When repair work is done to the lower part of the bath,
always support the bath.

Cleaning
Housing
Use a moist cloth to clean the housing. Never use solvents as
cleaning agents. Check the housing for defects (controls,
plugs).
Tube connections
Visually examine tube connections. Tears, brittleness are to
be corrected by replacing with suitable new tubes.
Sealing system
Visually check seal KD-34 and if it is strongly worn, replace it
with a new seal.
• Do not grease seal (abrasion and fat have abrasive effect).
• Cleaning by rinsing and drying with a soft cloth prolongs
the service life of seals. This also helps to keep solvents
from getting into the unit.
• Clean seals and glass components regularly, especially after
boiling delays and/or work with crystalline products.
