Warnings and Safety Precautions

PE Personal Evaporator

8. Use the System In A Proper Manner

Do not use the instrument and/or its accessories in a manner not specified by KD
Scientific. If you do so, the protection provided by safety interlocks may be impaired.

9. Do Not Attempt To Bypass Any Safety Interlocks

The safety interlocks are provided to comply with safety requirements of various
regulatory agencies and must be employed to protect the operator. The lid should be
fully down and the latch engaged when the instrument is in use. Do not use your
hands or any implement to slow the rotor at the completion of an evaporation
process. Allow the rotor to come to rest without interference. The motor is equipped
with a braking function which is engaged when the latch is disengaged and will stop
the rotor in just a few seconds.

10. Wear Gloves When Handling Dry Ice

Dry ice can cause serious burns to the skin. Casually dropping dry ice nuggets into
the trap can splash the ethanol liquid out of the internal cold finger. Use care when
adding dry ice to not cause a spill.

11. Ensure That Circulation Exists Between The Cold Trap Ports

The function of the Centrifan

TM

PE is to accelerate evaporation of sample solvent.

The solvent must be condensed out of the recirculating gas volume within the
instrument or continued evaporation will not occur. The outlet port at the back left of
the instrument and the inlet port at the back right should be connected in series with
a dry ice trap or a mechanical cold trap to obtain maximum green solvent recovery
benefit.

12. Avoid use of acidic solvents

The standard system is not designed to handle acid vapors. Extended use of acidic
reagents can cause degradation of internal parts (i.e. rusting will occur on stainless-
steal Liner). Use of acidic solvents will void warranty. Contact the factory for
information on ordering an “acid proof” system.
