1Using 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G and PD 8 G) the produced mono distillate can directly be withdrawn from the distillate outlet.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 The bi distillate, condensed on the cooling coil of the second-stage condenser, can be withdrawn from the dis-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.

electrical voltage
General warning
Before maintenance and repair
disconnect the unit all-pole from
the electrical mains (pull the plug
from the socket).
4Transport, Set-up and Location of the Distillation Apparatus
Protect yourself and the Distillation Apparatus during transport and setup by working carefully and
avoid danger of e. g. shifting or tilting the unit as well as risk of injury by lifting heavy loads. Caution, Dis-
tillation Apparatus PD 8 G, PD 2 DG and PD 4 DG with a net weight of 26 kg must be lifted, carried
and transported to the location by at least two persons. The Distillation Apparatus can be held between
the four stands of the unit and lifted for setup. The unit is suitable for both bench and wall mounting. It is
only suitable for indoor use. Table-top setting-up on solid, even and level surfaces only. Make sure to place the unit only
on a watertight, temperature-resistant, non-flammable surface. The location must provide sufficient space as well as the
necessary carrying capacity for the total weight of the Distillation Apparatus (unit weight as per Technical Data of this
manual, plus weight of the filling). For setting-up on the wall check the carrying capacity of the wall in connection with the
total weight of the unit (appliance plus water filling, see Technical Data). Make sure to check the on-site fixing elements in
order to guarantee safe hold of the Distillation Apparatus. The fixing material must be suitable for the substrate. Use only
tested and proven fixing material. There are two keyholes for wall mounting at the back of the Distillation Apparatus. Place
two fixing screws (not included in the scope of supply) in the wall, 40 cm apart, and nest the still on the keyholes. The Dis-
tillation Apparatus is delivered without fixing material. To protect the glass parts during transport, the inside of the Distilla-
tion Apparatus is filled with packing material, and all free openings are taped. These transport protections must be removed
before initiation. When installing the glass condenser and the glass fittings, pay special attention due to danger of glass
breakage.

5Operating Voltage
The Distillation Apparatus Models PD 2 G, PD 4 G and PD 2 DG must be connected to the mains supply through a cor-
rectly installed shock-proof socket. The models PD 8 G and PD 4DG must be connected to the mains supply through a
correctly installed on-site main switch, or, permanently connected, through a CEE plug in conformity with IEC standard
60309-2.
The unit is a protection class I electrical appliance, a connection to the protective earth is to be ensured.
For information on the value of the required mains fuse see Technical Data of these instructions.
The electrical connection must ensure an all-pole separation from the mains at any time. Shock-proof
sockets or main switches to separate the Distillation Apparatus from the mains must be installed in such a
way as to ensure clear identifiability and easy accessibility at any time.
The mains connection cable must not touch any hot surfaces of the unit. It may not lead underneath
the unit. The main switch of the Distillation Apparatus must be off (position O). The voltage on the
nameplate (at the left-hand side of the unit) must be identical to the mains voltage. If they are identical,
connect the unit to the mains.
Please also refer to chapter 13 of these operating instructions "Connection to the Mains"..
