4 Description of function

This chapter explains the basic working principle of the Rotavapor® R-220 Pro. It also shows how the instrument is structured and provides a general functional description of its assemblies.

4.1 Functional principle of a Rotavapor® evaporation

The Rotavapor® R-220 Pro oers ecient, time saving single-stage distillations for small and medium stage productional applications. The process is based on the evaporation and condensation of solvents or drying of powders and pasty materials in a rotating evaporating ask.

Standard vacuum applications

Due to its sophisticated seal system a highly stable vacuum level can be reached in combination with a vacuum controller and a vacuum pump. The vacuum also eliminates unwanted or hazardous emissions of vapors during the process and serves as an important safety feature. The low pressure decreases the boiling point of the medium inside the Rotavapor®. This allows to treat the product gently at even higher evaporation performance compared to environmental pressure operation.

Special applications

• For the oxydation of sensitive products, the processing can take place under inert gas conditions

4 Description of function

Safety reserve

Rotation drive for evaporating ask

Evaporating solvent

Heating bath with heating liquid

Evaporation area The solvent is heated by means of a heating bath. The turbulent mixing inside the rotating

evaporating ask results in an increased evaporation rate. The drive unit oers a wide range of rotational speeds to perfectly match dierent evaporation tasks. It also leads to an even mixing of the sample, thus preventing stationary overheating in the ask. When drying powders or pasty materials, the rotation ensures smooth and thorough drying.

Cooling area The solvent vapor quickly enters the condenser. Here, the energy in the solvent vapor is

transferred to the cooling medium (mostly water), so that the solvent condenses.

Receiving ask The receiving ask collects the condensed solvent.

NOTE For information about optimum distillation conditions see section 6, Operation.

4 Description of function

For most applications a vaccum is used to signicantly reduce the boiling point of the liquid content inside the evaporating ask.

The aeration valves at the optional vacuum controller and the aeration valve of the Rotavapor® are used to aerate the Rotavapor®.

Under inert conditions, both aeration inlets must be connected to an inert gas source with regulated output pressure equal to ambient air pressure!

If a Vacuum Interface I-300 Pro is installed, a tube connection must be established to detect the vacuum level inside the glassware.

When a chiller is used, up to 300 liters of mains water can be saved a day during operation. In addition, higher process safety and lower solvent emissions due to the constant, low cooling temperature can be achieved.

The cooling water valve can also signicantly reduce cooling water consumption by cutting o the water supply when no cooling is necessary.

Using the ask handler

The handler can increase the level of safety when placed on top of the heating bath at ask exchange. However, the ask handler is not suitable as an installation support! The lift mechanism does not stop automatically when the evaporating ask has reached its individual installation height!

Using the ask handler installed on the heating bath to lift or lower the evaporating ask can be dangerous for the operator and can cause device damages.

WARNING

Serious injuries by ying pieces of broken glass.

• Do not use the bath lift to install or deinstall the evaporating ask

• Do not operate the lift with the ask handler installed

Risk of instrument damage by wrong mains supply.

• External mains supply must meet the voltage given on the type plate

• Check for sucient grounding

NOTICE

55 R-220 Pro Continuous Operation Manual, Version A

5.18 Adjusting the snap ange

System tightness is essential when working with a Rotavapor®. Thus, the snap ange assembly should be checked at every evaporating ask installation. This is necessary since every glassware has its unique tting accuracy.

Clockwise = increasing the tension Counterclockwise = decreasing the tension

5 Putting into operation

• When passing the top dead center of the closing mechanism a clear resistance must be felt.

• Moving the lever must never require excessive force!

X If the required lever force is too weak the ange may not be thight and will wear out the PTFE

seal. In this case, increase the tension of the closure.

X If the required lever force is too high (e.g. the lever can not be shifted over the top dead center)

reduce the tension of the closure.

After readjustment, perform a vacuum test-run without heating bath and sample medium.

NOTE Perform the adjustment in single-turn steps only. Inbetween, check for proper tension with the empty evaporating ask.

6 Operation

This chapter gives examples of typical instrument applications and instructions on how to operate the instrument properly and safely. See also section 2.5 “Product safety” for general warnings.

NOTE Operation of the interface is explained in the operation manual of the Interface I-300 Pro.

6.1 Evaporation in three steps

a Preparational steps

• System must be in good working order. See nal installation check, section 5.21.

• Check level of heating transfer medium as described in section 5.16.

• Fill the evaporating ask with the product to maximally slightly below the half. Install the ask at the Rotavapor®.

6 Operation

Mount the ask and establish a weak vacuum e.g. 800 mbar. Feed the evaporating ask via the feeding-valve to maximally slightly below the neck of the ask.

• Close the splash protector if installed. Select the target heating bath temperature and start heating.

b Evaporation process

• Establish working pressure (see operation manual I-300 Pro).

• Lift up the heating bath completely. The evaporation will start shortly.

• With the heating bath at temperature start rotation and set rotational speed to the target value. At this time the cooling medium ow must be established!

• NOTE the condensation zone of the cooler during evaporation! Optimal cooling to evaporation ratio for safe use is reached at approx. 75-80% condensation zone height at the rst condenser. It is recommended to adjust the evaporation parameters to reach optimal condensation height e.g. to alter the cooling medium ow during operation.

• Foam formation under vacuum can be interrupted manually at any time during evaporation.

Press the 'Aearate' button in short steps to let the foam collapse

c Continuous operation

• Once distillation is running, the system can be switched to continuous mode by pressing the "Auto" button. As a result, the inow and outow are automatically controlled by the Rotavapor.

NOTE To remove solvent residues after evaporation remount the empty evaporating ask, close the system and evacuate the system to a very low pressure. Then aerate via the outlet of the receiving vessel and the ller-cock. Let the ask rotate to dry the seals at the gearbox thoroughly.

59 R-220 Pro Continuous Operation Manual, Version A

6.2 Optimal distillation conditions

To achieve optimal distillation conditions, all distillation energy supplied by the heating bath must be removed by the condenser. The physical cooling capacity of the condenser must not be exeeded in order to avoid steam emission by overpressure inside the assembly!

NOTE:

• A temperature gradient of 20 °C between 'heating bath → vapor' and 'vapor → cooling medium' is optimal for most distillation tasks. This rule can also be applied to other temperature ranges.

• During aeration (e.g. to suppress foam formation) the condensation height can decrease.

• Condensation over the complete condenser height is a sign for unsucient cooling capacity! Adjust the distillation parameters (e.g. lower the cooling medium temperature) to stabilize the condensation zone at approximately 2/3 to 3/4 during operation.

Cooling water source: max. 20 °C

6 Operation

Vapor: 40 °C

Bath: 60 °C

Typical distillation parameter settings:

• Set the bath temperature to 60 °C.

• Use cooling water / medium with less than 20 °C.

• Allow cooling water / medium to ow through the condenser at approximately 120 — 150 l/h.

• Adjust pressure parameter to reach a boiling point of ~40 °C for the used solvent. In most cases it is necessary to apply a vacuum! Information about the corresponding pressure for common solvents can be found in the following ‘Solvent table’.

Advantages associated with bath temperatures of 60 °C:

• Water can be used as heating medium (cost ecient, good availability)

• Comparatively low comsumption of heating energy compared to higher bath temperatures

• Gentle product treatment at moderate temperature

• Shorter cooling-o time for evaporating ask and heating medium
