Using of the Glass Distillation Apparatus
Intended Use
In LAUDA Puridest Glass Distillation Apparatus models PD 2 G, PD 4 G, PD 8 G, PD 2 DG and PD 4 DG, quartz-
sheathed heating elements serve to boil water and evaporate it. The steam is led from the glass boiler to a condenser with
splash guard and condenses on a water-cooled cooling coil. In Glass Mono Distillation Apparatus (models PD 2 G, PD 4
G and PD 8 G) the produced mono distillate can directly be withdrawn from the distillate outlet. In Glass Bi Distillation
Apparatus (models PD 2 DG and PD 4 DG) the produced mono distillate is evaporated again in a second, following distil-
ling stage. The bi distillate, condensed on the cooling coil of the second-stage condenser, can be withdrawn from the dis-
tillate outlet. All assembled glass construction parts are made of Duran® / borosilicate glass 3.3, the heating elements are
quartz-sheathed. The inside tubing consists of high-temperature resistant silicon hose. After switching the Distillation Ap-
paratus on, operation is controlled automatically.
Depending on the quality of tap water, the produced mono distillate of models PD 2 G, PD 4 G and PD 8 G has a con-
ductivity of approx. 2.2 µS/cm at 25 °C. In models PD 2 DG and PD 4 DG, the mono distillate is used to produce bi dis-
tillate in a consecutive distillation stage. The produced bi distillate is dependent on the quality of the evaporated mono dis-
tillate and has a conductivity of approx. 1.6 µS/cm at 25 °C.
The quality of the distilled water is, among other things, dependent on the composition of tap water as well as on the
cleanliness of the distillation stages. The distillate quality should be controlled in regular intervals and be compared with the
requirements of the relative application.
To feed the Distiallation Apparatus, preferably use tap water of drinking quality. Please also observe the information in
chapters „Accessories and Options“ of these instructions on the possible use of filters and cartridges to pretreat the tap
water.
The Bi Distillation Apparatus must be operated within the user's field of vision.
The information contained in these operating instructions must by all means be read and observed. Only
then a perfect operation of the Bi Distillation Apparatus can be guaranteed. The units may only be installed
and operated by persons who have made themselves familiar with these operating instructions.
Caution:
The accessible inner parts of the housing that can be reached after removing the front screen get strongly
heated up during operation. These parts must only be touched after they have cooled down, or when wear-
ing suitable safety gloves.
Improper Use
LAUDA Puridest Glass Distillation Apparatus, operated in a laboratory, are no Medical Devices. They fall neither under
national nor international Medical Device Directives and have to be used and applied accordingly. The Distillation Appa-
ratus must not be used in potentially explosive surroundings, e. g. during anaesthesia with inflammable gas or steam types .
The Distillation Apparatus must neither be set up nor operated in laboratory areas with aggressive or corrosive ambient
conditions.
