The RC 600 rotary evaporator is designed for distillation and
evaporation of solutions. The rotary evaporator is operated via
the terminal (Fig. 1/2, p. 15).

The solution that is to be evaporated is located in the evapora­tion flask (13). The solution is evaporated through a suitable
combination of temperature and vacuum. The evaporation
flask is immersed into the heating bath (14), in which a heating
liquid is located, typically water or a suitable oil. The drive (8)
continually rotates the evaporation flask in the heating bath.
Once the solvent begins to evaporate, it rises through the va­pour tube and into the chilled condenser (6), which is continu­ally cooled with cooling water or another cooling medium. Here
the vapour is cooled to the point where it condenses and col­lects (again in liquid form) in the collection flask (3).

The chilled condenser and collection flask have a transparent
coating that protects them against implosion.

A protective cover (accessory) is placed onto the heating bath
to protect the evaporation flask from implosion and to protect
against spray.

5.2 Rotary evaporator functions

 Evaporation flask

Use the rotary knobs (Fig. 1/12+18) to adjust the evapora­tion flask's angle of inclination. Together with the ability to
move the evaporation flask up and down and to displace
the heating bath, the rotary evaporator may be adapted to
various shapes and sizes of evaporation flasks.
The drive (8) rotates the evaporation flask, thereby
achieving a high rate of evaporation:

-

A more homogeneous distribution of temperature is
achieved both in the heating bath and in the evapora­tion flask (optimisation of temperature control and heat
transfer).

-

The moistened surface inside the evaporation flask is
enlarged (increases heat transfer and the boiling sur­face).

-

Formation of a concentration gradient in the solution is
avoided.

Additional advantages of rotation include:

-

The risk of boiling delay is reduced

-

No localized overheating, no crust formation

The terminal (2) is used to switch the rotation of the evapo­ration flask on or off and to select the desired speed (see
Chapter 8, Operating the rotary evaporator).
In the event of a power failure the evaporation flask is au­tomatically lifted from the heating bath.

 Heating bath

Use the rotary evaporator's heating bath (14) to
achieve and maintain the temperature for optimum dis­tillation according to requirements.
The heating bath may be pulled out on guide rails in

Operating Instructions RC600 EN Components and functions

Translation of original Operating and Installation Instructions, English, BA_RC600_EN_304763_20170608.docx 17

order to permit the use of a wide range of evaporation
flask sizes (see section Evaporation flasks).
The specially shaped pouring lip makes it easier to
empty the heating bath.

Returns Operating Instructions RC600 EN

52 Translation of original Operating and Installation Instructions, English BA_RC600_EN_304763_20170608.docx

13 Returns

Pumps and systems used in laboratories and process-based
industries are exposed to a wide variety of conditions. This means
that the components contacting transferred media could become
contaminated by toxic, radioactive, or otherwise hazardous sub­stances.

For this reason, customers who send any pumps or systems back
to KNF must submit a Declaration of No Objection and Decontami­nation in order to avoid a hazardous situation for KNF employees.
This Declaration of No Objection and Decontamination provides
information about, for example:

 physiological safety

 whether medium-contacting parts have been cleaned

 whether decontamination was completed

 media that have been transferred or used

and must declare physiological safety. To ensure worker safety,
work may not be started on pumps or systems without a signed
Declaration of No Objection and Decontamination.

For optimal processing of a return, a copy of this declaration
should be sent in advance via e-mail, regular mail, or fax to KNF
Customer Service (refer to final page for address). In order to avoid
endangering employees who open the shipment's packaging,
despite any residual hazards, the original version of the Declara­tion of No Objection and Decontamination must accompany the
delivery receipt on the outside of the packaging.

The form for the Declaration of No Objection and Decontamination
is included with these operating instructions and may also be
downloaded from the KNF website.

The customer must specify the device type(s) and serial number(s)
in the Declaration of No Objection and Decontamination in order to
provide for the unambiguous assignment of the Declaration to the
device that is sent to KNF.

In addition to the customer's declaration of physiological safety,
information about operating conditions and the customer's applica­tion are also of importance to ensure that the return shipment is
handled appropriately. Therefore, the Declaration of No Objection
and Decontamination requests this information as well.
