Clean off any adhered dirt or debris by washing the sample holders in soapy water or using a
cleaning solvent such as methanol or acetone. The sample holders should then be rinsed in
clean water. Alternatively, wash in a dishwasher at 90°C. Check to make sure that all
adhered dirt, debris or solvent residue is removed. Always dry the sample holders
thoroughly after cleaning and never place wet sample holders in a Genevac system.
Repeated use of sample holders with strong acids may cause colour fading over time; this is
normal and does not affect the integrity of the sample holders.
Caution: Excessive build up of deposit on the pivoting faces of the sample
swings and rotor can cause the sample swings to stick in the out position when
the rotor stops, resulting in unrecoverable sample loss.
Caution: Scratches or superficial damage on the surface of sample holders will
not affect performance, however if there is any structural damage (if any part of
the swing or sample holder is bent or deformed, or if there is any sign of a crack)
do not use it. Contact Genevac Service for evaluation.
Planned maintenance and servicing
Whilst every effort is made to design and manufacture evaporation systems to the highest
possible standard, there will be some degree of degradation due to wear and ageing of parts
such as seals and bearings within the evaporator, condenser and pump. The extent of wear
and ageing depends on the use of the system, the severity of temperature cycling and the
nature of the solvents used. In addition, some solvents may eventually cause pin-hole
corrosion in the connecting tubes, resulting in a decline in performance.
In order to maintain peak performance and avoid costly and unscheduled down time,
Genevac strongly recommend implementing a schedule of planned maintenance. Changing
parts in the field is complex and requires a high level of skill. Genevac offers a range of
preventive maintenance, service and breakdown contracts designed to keep the equipment
in top condition.
