6 Functions V-805

6.2.3 Distillation with timer function

The set point of system pressure and distillation duration are input. When the distillation starts, the system pressure is reduced to the input value and kept constant during the selected period. At the end of the input distillation time, the distillation is stopped. If so configured, rotation of the rotary evaporator is stopped and the flask is lifted from the bath.

6.2.4 AUTODEST function (only with automatic

dual temperature sensor)

Allows full automatic distillation without input of parameters until dryness, if physically possible. As soon as the evaporating flask is dry, distillation is stopped. If so configured, rotation of the evaporating flask is stopped and the flask is lifted from the bath.

6.2.5 The TEMPERATURE function (only with

automatic dual temperature sensor)

Distillation is carried out on the automatically found pressure. As soon as the vapour temperature drops, distillation is stopped. If so configured, rotation of the evaporating flask is stopped and the flask is lifted from the bath.

6.2.6 The REPEAT function

The last, for example, manually performed distillation can be repeated and stored for later use (learning by doing). This is a valuable function for difficult distillations, which must be performed repeatedly, in which the parameters must be experimentally determined and optimised.

6.2.7 Working memory

The last mode used and associated values are kept in the working memory after the apparatus is turned off and are automatically recalled when the apparatus is turned back on.

6.2.8 Memory of methods

Memory for 5 complete distillation programs. Memory management with the help of conventional functions, Storing,

Retrieving, and Deleting.

8.8 Automatic distillation (only with connected auto sensor)

8.8.1 Preconditions for an automatic distillation

The automatic dual temperature sensor is based on a balance adjustment of the temperature in the condenser with consideration of the cooling material temperature. For troublefree distillation until dryness, the following conditions must exist:

• minimum solvent quantity 50 … 100 ml.

• Boiling point differences in the case of solvent mixtures is

not greater than 45…50°C. Greater differences lead to back evaporation from the receiving flask and stopping of the apparatus.

• Temperature difference between heating bath and cooling

35…45°C.

It is difficult to evaporate solvent mixtures with very large boiling point and/or evaporation heat difference in automatic mode. This includes many aqueous solvent mixtures.

You cannot add anything to the evaporating flask in the automatic mode. To do this, the controller must be changed into the manual mode, the material added to the evaporating flask and then the apparatus must be changed back into the automatic mode.

8.8.2 Performing automatic distillation

Choose the autodist function [MENU] ð [MODE] ð [AUTODEST.] (if it is not already active). The display changes

9 Information on choosing

distillation conditions

45: “20-40-60”

Condensation range

9 Distillation conditions

To achieve optimum distillation conditions when rotary evaporators are used, the energy, supplied for distillation from the heating bath, must be removed via the condenser. To guarantee this, operations should be performed according to this rule of thumb.

Cooling water Vapour Bath max. 20°C40°C60°C

How can you achieve these conditions?

• Set the bath temperature to 60 °C

• Set cooling water, temperature no higher than 20°C

• Allow cooling water to flow through the condenser at approximately 40 – 50 l/h

• The working vacuum is to be chosen, so that the boiling

point of the solvent is 40 °C. You can get the corresponding pressure from the Solvent Table (next page).

Advantages associated with 60 °C bath temperature:

• The evaporating flask can be replaced without risk of scalding.

• The evaporation rate of the water from the heating bath is not very high (energy loss).

• The heating bath energy is employed at a good degree of efficiency.

This rule can also be applied to lower bath temperatures, for example:

Cooling water Vapour Bath max. 0°C20°C40°C

Optimising distillation: Depending on distilled solvent, distillation may have to be

optimised again. However, before you optimise distillation again, the heating bath must have reached 60 °C.

The following applies: condensation of solvent should be 2/3 to 3/4 of the existing condenser coil.

There are basically two possibilities for optimising distillation:

1. Slowly reduce pressure again

Bath must have reached 60 °C (Boiling point is reduced, increase of ∆T1, resulting in increase of distillation capacity) or

2. increasing bath temperature

(Increase of ∆T1, resulting in increase of distillation capacity).

By increasing the bath temperature, not all of the additional energy is supplied to distillation, but more is also discharged into the environment. This is due to the increase temperature difference between bath and environmental temperature.
