4 Description of function

This chapter explains the basic working principle of the Rotavapor R-220 SE. 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 SE offers efﬁcient, 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 ﬂask .

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.

4 Description of function

Special applications

• In combination with the dry ice condenser (conﬁguration ‘C’) distillations at lowest temperatures can be achieved

• 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 ﬂask

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 ﬂask results in an increased evaporation rate. The drive unit offers a wide range of rotational speeds to perfectly match different evaporation tasks. It also leads to an even mixing of the sample, thus preventing stationary overheating in the ﬂask. 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 ﬂask The receiving ﬂask 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 signiﬁcantly reduce the boiling point of the liquid content inside the evaporating ﬂask.

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 Controller V-850 / V-855 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 signiﬁcantly reduce cooling water consumption by cutting off the water supply when no cooling is necessary.

connected when a heating medium different to water is used!

Flow reducing valve The valve can be used to reduce the cooling water ﬂow to

achieve the best cooling to water consumption ratio.

Condensate cooler This cooler inhibits evaporation from the receiving ﬂask. It is part

of some glassware conﬁgurations.

Cooler(s) Depending on the type of glassware conﬁguration, one or more

coolers can be connected in serial.

Cooling water output to sink / return loop to chiller

The warmed cooling water can be disposed of into a sink or reused in a closed cooling cycle when a chiller is used.

5.9 Glassware and conﬁgurations

All original glassware parts and accessories are of superior quality. However, glassware is generally fragile and must be handled with appropriate care to achieve a long lifetime and safe use. Every glassware part must be inspected visually prior to use to ensure safe and proper functionality.

Visually inspect glassware for:

• Cracks and splinters

• Scratches and blunt spots

• Proper condition of safety coating “Plastic+Glas”

CAUTION

Risk of minor or moderate cuts when handling damaged glass parts.

• Handle glass parts with care

• Visually inspect every glass part before mounting

• Exchange damaged glass parts immediately

• Do not touch cracks or bits of broken glass with bare hands

5 Putting into operation

NOTE

• Clean all glass parts before mounting to avoid cross contamination.

• “Plastic+Glas” coating is not dishwasher proof! Clean coated parts manually with a soft cleaning

detergent.

5.10 Additional cleaning measures for food, pharma and cosmetic applications

For food, pharma and cosmetic products additional meassures are required during the whole evaporation process to establish the necessary hygienic level. Any risk of infection, deseases or contagion must be excluded!

NOTE

It is highly recommended to use a new set of tubes and bacteria ﬁlters to further reduce the risk of contamination between two evaporation processes. The ﬁlters must either be sterile or disinfected prior to use.

Steps to a controlled hygienic processing:

• All parts in touch with the product must be clean and disinfected

• The system must be tight

• All air/gas in- and outlets must be equipped with a bacteria ﬁlter

5.10.1 Primary cleaning

All glassparts can be manually rinsed with a disinfection medium under hygienic conditions. Primary cleaning can be done mechanically e.g. by means of a disinfected brush. However, the primary cleaning must effectively remove all residua of previous operations! Because of the bandwith of possible materials to be processed with the Rotavapor it is not possible to recommend a general purpose detergent. Contact your local hygienic specialist or BUCHI representative for a suitable detergent for your speciﬁc application! Note the material list in section 3.3. Clean all used hoses with isopropanol 70 % and bake them out at 110 °C for 30 minutes.

46 R-220 SE Operation Manual, Version F

Page 47

All sealings in contact with the product have a PTFE surface and can be disinfected in an ultrasonic bath with a corresponding disinfection medium. At reinstallation, mind hygienic handling!

NOTE

Do not bring the seals in contact with lubricants or other harmful substances!

After cleaning, the system must be assembled to run a disinfection cycle, see below.

5.10.2 Example for a disinfection via an evaporation cycle

For evaporation under hygienic conditions it is vital to establish a closed processing. Due to the functional principle all in- and outlets to environmental air or inert gas must be sealed with a bacteria ﬁlter.

Preparational steps for disinfection cycles:

• Connect a tube to every aeration valve inlet and install a bacteria ﬁlter at the end of the tube(s) to prevent contamination by environmental air ingress.

When working under inert conditions:

• Install a ﬁlter between the inert gas source and the gas inlet of the glassware setup.

5 Putting into operation

NOTE

If the system is equipped with two receiving ﬂasks switch between both ﬂasks during the running disinfection evaporation!

Empty the evaporating and the receiving ﬂask and rinse the evaporating ﬂask with water. Fill 1.5 l of isopropanol into the evaporating ﬂask and start the evaporation under the following condi- tions: Heating bath set to 60 °C, vacuum set to 250 mbar (corresponds to a boiling point of isopropanol of 50 °C), chiller set to 7 °C. At ﬁrst, switch off the chiller or cooling water until the vapor has passed the whole instrument. Then switch on the chiller or cooling water and distil off 0.75 l. Afterwards empty the evaporting and the receiving ﬂask and dry the instrument at a vacuum of < 20 mbar.

5.11 Veriﬁcation of the disinfection process

BÜCHI Labortechnik AG carried out a test to verify the disinfection process. The samples resulting from the test procedure were sent to the Labor für Hygiene und Praktische

Mikrobiologie AG, Chleematte 14, CH-5243 Müllingen, a Swiss Testing Service STS 486 according to ISO/IEC 17025. There, a photometric haze measurement according to ISO 4833:2003 was carried out to determine the germ concentration.

The following test setup was used: Test instrument: Rotavapor R-220 SE, system conﬁguration D with Vacuum Pump V-710 and recircu-

lating chiller.

Both aeration valves were closed with an aseptic ﬁlter Sartorius Midisart 2000, 0.45 µm and an inline ﬁlter PAL Kleenpak 1.2 µm was ﬁxed in the vacuum line between instrument and pump.

The following representative test contaminants were used:

• Escherichia coli ATCC 25922

• Staphylococcus aureus subsp. Aureus ATCC 25923

• Saccharomyces cerevisiae NCYC 79

• Geobacillus stearothermophilus

5.14 Heating bath ﬁlling level

The optimal ﬁlling level of the heating transfer medium in the bath ensures maximum evaporation performance and safe handling. Depending on the evaporating ﬂask size, the level has to be adjusted.

Filling procedure

• Mount the evaporating ﬂask and drive up the bath.

• Select heating transfer medium according to the target temperature. Mind the limitations for the different heating types!

• With the bath in highest position, ﬁll in heating transfer medium.

5 Putting into operation

Install the draining valves with two EasyClamps (DN 25).

The ﬁlling level should be a ﬁngerbreadth below the level drain output with the evaporating ﬂask immersed. During rotation of the evaporating ﬂask at target speed, no heating transfer medium should spill or splash.

CAUTION

Risk of minor or moderate injuries by hot surfaces at the draining tap and level drain output.

• Let the bath cool down below 40 °C before touching these items

NOTE

If the drain is not connected to a sink, install the drain cap to seal the heating bath.

• The medium must be liquid at room temperature.

• Do not mix liquids of unknown composition!

DANGER

Death or serious burns by use with highly ﬂammable substances in the heating bath.

• Do not use heating transfer medium with a ﬂash point below 200 °C

• At liquid exchange, the heating bath must be clean and dry

DANGER

Death or serious burns by deﬂagration of hot heating bath liquids.

• Do not mix or add water to other heating transfer media with a higher boiling point

• The replenishment valve must not be connected to a water source when another heating transfer medium than water is used

NOTE

• Do not switch on the heating when the heating transfer medium level is unsufﬁciently low for evaporation tasks.

• Drain and clean the bath regularly to maintain the system in good working order.

• Ambient humidity can diffuse into the heating medium and condensated water can gather at the bottom when the bath has not been used over a longer period. To drive out unwanted water let the evaporating ﬂask rotate and heat up the bath above 100 °C for some minutes.

5.17 Attaching and removing evaporating ﬂasks

Evaporating ﬂasks are available in different types and sizes to meet all kinds of application requirements. However, the maximal load on the rotational ﬂange must not exeed 20 kg!

CAUTION

Risk of minor or moderate injury by heavy weight of the evaporating ﬂask.

• Clean and dry the exterior of the ﬂask before installation and removal

• Lift the ﬂask carefully and avoid overexertion

• Do not drop the ﬂask

• Savely support the ﬂask at handling

• Savely store the ﬂask onto a matching ﬂask ring or holder

• Keep limbs out of crushing zone

WARNING

Risk of serious burns by hot heating bath content.

• Do not drop any parts into the heating bath

• Wear protective clothes against hot liquid spills

5 Putting into operation

Drive down the heating bath.

Support the evaporating ﬂask by hand or with the optional ‘Manual ﬂask handler’ (order no.

41400). Lift the lever of the snap ﬂange. See also section 5.10 for correct adjustment of the lever tension!

Swivel out the right half of the snap ﬂange.

62 R-220 SE Operation Manual, Version F

Page 63

5 Putting into operation

Push down the unlock rocker at the left half of the snap ﬂange.

Open the snap ﬂange completely and carefully take away the evaporating ﬂask.

Using the ﬂask handler The handler can increase the level of safety when placed on top of the heating bath at ﬂask

exchange. However, the ﬂask handler is not suitable as an installation support! The lift mechanism does not stop automatically when the evaporating ﬂask has reached its individual installation height!

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

WARNING

Serious injuries by ﬂying pieces of broken glass.

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

• Do not operate the lift with the ﬂask handler installed

63 R-220 SE Operation Manual, Version F

Page 64

5 Putting into operation

Risk of instrument damage by wrong mains supply.

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

• Check for sufﬁcient grounding

NOTICE

5.18 Adjusting the snap ﬂange

System tightness is essential when working with a Rotavapor. Thus, the snap ﬂange assembly should be checked at every evaporating ﬂask installation. This is necessary since every glassware has its unique ﬁtting accuracy.

Clockwise = increasing the tension

Counterclockwise = decreasing the tension

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

• Moving the lever must never require excessive force!

➡ If the required lever force is too weak the ﬂange may not be thight and will wear out the PTFE seal.

In this case, increase the tension of the closure.

➡ 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.

64 R-220 SE Operation Manual, Version F

Page 65

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 ﬂask.

5.19 Installation and usage of a shut-off tap

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.

6.1 Evaporation in three steps

a Preparational steps

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

• Check level of heating transfer medium as described in section 5.13.

• Fill the evaporating ﬂask with the product to maximally slightly below the half. Install the ﬂask at the Rotavapor.

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

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

6 Operation

b Evaporation process

• Establish working pressure. Press the 'Start' button at the controller or manually set the vacuum level.

• 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 ﬂow 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 ﬁrst condenser. It is recommended to adjust the evaporation parameters to reach optimal condensation height e.g. to alter the cooling medium ﬂow during operation.

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

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

press the '↑P ' button at the controller to increase the pressure permanently during the ongoing evaporation process. Stop increasing the pressure shortly above the foam formation limit for best process performance.

c After evaporation

• In case the Rotavapor is equipped with a controller, pressing the 'Stop' button at the controller will automatically stop heating, rotation and vacuum. Aeration will be done via both aeration valves.

Stop heating, stop rotation and drive down the heating bath manually. Depending on the device setup it might be necessary to switch off the vacuum source manually. Aerate the Rotavapor and wait approx. 5 minutes before interrupting the cooling medium ﬂow.

• Open the splash protector if installed.

• Unmount the evaporating ﬂask.

NOTE

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

68 R-220 SE Operation Manual, Version F

Page 69

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 unsufﬁcient 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 ﬂow 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 efﬁcient, good availability)

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

• Gentle product treatment at moderate temperature

• Shorter cooling-off time for evaporating ﬂask and heating medium

7.2 Regular service and checks

To maintain the system in good working order the checks described in this section should be performed regularly. Defective or worn out parts must be exchanged directly to ensure safe use and optimal efﬁciency.

7.2.1 System tightness

To evaluate the system tightness, evacuate the unit to below 100 mbar and then close the vacuum line. The rate of pressure rise must not exceed 1 mbar per minute. A greater pressure rise indicates a leakage. In such a case, recheck all EasyClamp connections, seal rings and valves for proper seating.

7.2.2 Sealings and hoses

Check for wear and clean the vacuum seal at least every six months. Check all other seals and hoses for wear at least yearly.

➡ Exchange seals with scratches or other harms directly.

7 Maintenance and repairs

NOTE

• To prevent damaging the seals never apply grease or touch them with sharp objects.

• To prolong the lifetime of the seals, rinse them routinely with water or ethanol to remove possible contamination with sample material.

• Dry the cleaned seals with a soft, lint-free cloth.

• PTFE seals need a 10 hours run-in period to reach their optimum tightness condition. This is normal for a PTFE seal.

7.2.3 Glassware and clamps

Clean all glass components after a distillation process to prevent cross-contamination.

• Inner surfaces

➥ Cleaning can be done by distillation of ethanol or acetone (product residues must be soluble by

the distilled cleaning agent).

• Outer surfaces

➥ Cleaning of outer parts can be done manually with warm water and a commercial cleaning

agent (e.g. mild soap solution).

• Smaller parts such as clamps can be cleaned in an ultrasonic bath.

➡ Visually check all glass components and clamps for damages subsequently.

NOTE

• It is recommended to decalcify the cooler spiral regularly to prevent calciﬁcation.

• Regularly ﬂush the cooling spiral with cleaning detergent to remove algae.

7.2.4 Housing, heating bath, cables and accessories

Check the housing, cables and accessories for visible defects (cracks, kinks etc.). Clean housing parts regularly with a damp cloth. Soapy water can be used as cleaning agent.

8 Troubleshooting

This chapter helps to resume operation after a problem has occurred with the instrument which does not require special technical training. It lists possible occurrences, their probable cause and suggests how to remedy the problem. The troubleshooting table below lists possible malfunctions and errors of the instrument. The operator is enabled to correct some of those problems or errors by him/herself. For this, appropriate corrective measures are listed in the column “Remedy”.

8.1 Resetting the over-temperature protection

For safety reasons (e.g. if no heating medium is in the bath) the over-temperature protection mechanically cuts off the heating current at temperatures above 205 °C. The overtemperature protection is located at the heating element distribution box.

8 Troubleshooting

• Switch off the Rotavapor and wait some minutes for the heating elements to cool down after the mechanism has been activated.

• Check for correct level of the heating transfer medium and take corrective actions if necessary!

• Push in the reset button by hand.

• Switch on the Rotavapor and perform a functional test of the heating.

➡ If the overtemperature problem still exists call for service!
