1. Where reference is made to Findenser, actions also apply to Findenser Mini unless otherwise stated.
2. In addition to this operating manual, refer to the manufacturers operating instructions for your hotplate and heating block before use with Findenser.

Setting up Findenser

• Please observe all instructions, notes and warnings given in this section while setting up the Findenser.
  • Label all points where surface temperatures above 50 °C can be reached, using the legally required warnig signs.
  • Findenser may be used with a wide range of reaction vessels (round bottomed, pear shaped or florentine).
• Select your hotplate and site on a level surface in your fumehood, ensuring there is adequate working space around it. It is important to maximise airflow around Findenser to allow heat transfer from the fins via air convection.
• If applicable, select an appropriate heating block for your application and position it on the hotplate stirrer.
• Put the vessel into the heating block or position it on the hotplate stirrer.
• Once in the heating block the vessel must be securely clamped around the central neck and attached to a support framework.
• Add all reaction contents and magnetic stirrer bar to the flask. ➜ Place the cone of the Findenser into the socket of the vessel, and check that the connection is fully seated.
  ➜ Fix the clamp with the aid of a boss to a retort stand or rigid framework, then position the jaws around the Findenser body and tighten.

Caution: Risk of leakage

• Failure to check that the joint between the vessel and Findenser is properly seated and aligned may result in loss of solvent during the reaction process.
• Ensure that the inner surface of the socket on the vessel and the outer surface of the cone on the Findenser are clean and free of any dirt or chemical residue.

Operation

Caution: Risk of breakage

• Failure to check that the joint between the vessel and Findenser is properly seated and aligned may result in the glass cracking in either the flask or the Findenser.
• Check the alignment of the vessel and Findenser assembly, this should be completely vertical. The assembly must not be subjected to any mechanical stress.
• Only use clamps suitable for a diameter up to 85 mm. Other clamps may be used but care should be taken that the jaws of the clamp have a suitable liner (cork or plastic). Failure to observe this will result in damage to the Findenser surface.
• For optimum stability, the clamp should be positioned on the upper half of the Findenser body.

Caution: Risk of deformation

• Excessive tightening of the clamp on the Findenser aluminium body may result in damage to the fins of the Findenser.
• Clamp the Findenser without the use of tools or keys.

1. Make sure that the assembly is completely vertical and stable, and check that the all connections are fully seated.
2. Additional glassware such as a dropping funnel, may now be attached to the side arms if a multi-neck vessel is being used.
3. If an inert gas is required, this should be added through the top joint of the Findenser with the use of a suitable right angled adapter and oil bubbler.

Operation
Please observe all instructions, notes and warnings given in this section while using the Findenser.

• Always refer to the manufacturers operating instructions for your hotplate and heating block before use with Findenser.
• Operate only in a fumehood with protective safety sash.
• Use of Findenser in ambient temperatures greater than 24°C or in the following conditions may lead to reduced performance:
  • extremely low boiling point solvents such as ether where volumes are greater than 100 ml
  • heating is more than 10°C above the boiling point
• Findenser is resistant to the majority of solvents and splash-resistant to dilute acids and alkalis at room temperature.
• Extended exposure to acids or alkalis will attack the surface of the Findenser. It is important to clean off any residual chemical spills immediately after they occur.

1. Once heating has started it is important to regularly monitor the reactor set up to ensure that excessive heat is not being applied.
2. If boiling of solvent, or refluxing appears vigorous, then the temperature of the hotplate controller must be turned down.

Cleaning and Maintenance

Caution: Risk of damage to the Findenser

• The processing of solvents with a boling point above 155 °C may result in damage to the Findenser.
• Findenser can only be used with the full range of organic solvents, with boiling points up to 155 °C.

1. If using a heating block, care should be taken to optimise the heating performance. Refer to operating instructions for your heating block.
2. If attempting to work under reflux conditions it is usually necessary to set the hotplate stirrer to a temperature above the boiling point of the solvent in use. Care should be taken to minimise this temperature, such that a gentle reflux is achieved. This would typically be 5 °C to 10 °C above boiling point of the solvent in use. Failure to observe this will result in excessive heating, resulting in vigorous refluxing and a loss of solvent from the reaction mixture.

Caution: Risk of damage to the Findenser
There is a risk of escaping of solvent vapor in overloading conditions.

Please observe the following limits:

• Findenser is designed to be used with flasks up to 2 litres and a maximum solvent volume of 1 litre.
• Findenser Mini is designed to be used with flasks up to 250 ml and a maximum solvent volume of 125 ml.

Once the reaction has finished, the heat source should be switched off and the system allowed to cool to ambient temperature.

Warning: Risk of burning

• There is a risk of accidental burns caused by coming into contact with hot surfaces.
• The Findenser can get very hot during operation. Avoid skin contact and allow the Findenser to cool to ambient before dismantling.

Cleaning
Please observe all instructions, notes and warnings given in this section while setting up the Findenser.

• Before cleaning, allow the Findenser to cool to ambient temperature and dismantle the assembly as described in section Disassembly and Storage.
• Flush the internal glass surfaces with a suitable cleaning solvent such as acetone. This is best achieved with a wash bottle.
• External exposed glass surfaces may also be cleaned with a suitable solvent.

Warning: Risk of injury

• Cleaning solution may cause skin and eye irritation.
• Use requiered personal protective equipment and observe the applicable general and safety instructions of the manufacturer.

Caution: Risk of environmental damage

• Cleaning solution may cause environmental damage.
• Always use cleaning solution with due care. Allow washing solvent to drain into a suitable receptacle. Spilled chemicals and solvents must be removed immediately.

1. Wash the whole Findenser assembly in warm soapy water, using a soft brush to clean fins.
2.  Rinse with warm water both internally and externally.
3. Allow to air dry.
4. Findenser may be dried in an oven provided the over temperature does not exceed 60 °C.
