3 Function
3.1 Working with the glass ovens
The core of the glass oven comprises two borosilicate glass
tubes lying one within the other. The outer tube (1) protects
against damage to the heating tube, and at the same time
prevents contact with parts that are electrically live. A metal
screen (2) around the outer jacket provides additional protec-
tion. The transparent, electrically conductive semi-conductor
coating, does the actual heating. Temperatures up to 300°C
are attained, the oven temperature being monitored via an
integral temperature sensor (4). A lock nut (5) can be used
to tilt the oven and to secure it in a suitable position.
The basic equipment can be used for drying,
distilling and sublimating, if the appropriate ac-
cessories are used.
To avoid thermal damage to, or decomposition of, samples
requires gentle heating techniques. Conventionally, this has
been done by heating the sample via an intermediate medium
(e.g. water or oil) whose temperature is regulated just above
the required setpoint for the sample. In bulb-tube distillations,
a semi-conductor coating is used to provide direct, yet still
gentle, heating. The product may be heated directly because
the heat source provides evenly across the entire surface
of the heater. Because the thermal capacity and the thermal
conductivity of the vapour-coated glass are significantly bet-
ter than those of the gas/atmosphere outside, most of the
heat given off is taken up by the glass and radiated inwards.
There are further advantages in addition to the gentle heating:
Because 75% of the heat is supplied to the product through
radiation and only 25% via heated gas, the oven heats up
very quickly and also cools down relatively quickly when it is
switched off. In addition, because the semi-conductor is fully
transparent, the sample can be observed during the drying
process, so that any decomposition can be identified quickly
and any necessary countermeasures can be taken in time.

Any damage suspected of having occurred during transportation
should be reported immediately to the appropriate authorities
(ditributor, post office, railroad or trucking company).
The original packaging should be saved in case it is required
at a later date.
4.1 Installation Location
The device must be set up on a clean, stable and level surface.
The device may not be used in rooms meant for use with ex-
plosive gases.
For safety reasons, there must be at least 30 cm between
the wall or other equipment and the rear and sides of the device.
No containers, chemicals or other devices should be placed
behind the device.
4.2 Power connections
Check to ensure that the voltage coming out of the electrical
socket agrees with the voltage stated on the devices ratings
plate. The glass oven must always be connected to an earthed
electrical socket. External couplings and extension cords must
have an earth wire (3-pole couplings, cords and sockets). It is
prohibited to cut or interrupt the earth wire. to avoid the risk of
damage to the device, or personal injury.

5.3.2 Drying
The glass oven can also be used to dry solid substances.
Unlike permanently installed drying cabinets, the drying oven
only has to heat up a small volume. It requires less energy,
reaches the desired temperature more quickly, and thereby
reduces the time for drying. Moreover, if used as a vacuum
oven, it has a significantly tighter seal than a drying cabinet
and can therefore maintain a better vacuum. There are three
methods used for drying direct drying, indirect drying, and
rotary drying. The drying accessory is used for direct and
indirect drying, the rotary flask for rotary drying.

5.3.3 Filling with the Material to be Dried
The drying accessory consists of three parts. While the drying
is in progress, the drying tube ainto which the product is
put (either directly or inside a container), is in the oven. The
end cap bthat catches the moisture evaporated off can be
filled with desiccants to improve the drying effect. A stop-
cock c is used to evacuate or aerate the sample chamber.
The aluminum flange ring djoins the two glass sections
in a screwed joint, sealing them vacuum-tight. The flange
ring eis also used to hold the drying accessory in position
within the glass oven. This drying accessory does not rotate.
The material to be dried can be placed in the drying tube in va-
rious ways. The method chosen depends mainly on the amount
of substance.
Example A
A large quantity of the material to be dried is placed directly in
the drying tube. With this method, existing glass boats, metal
dishes, etc., may be used. This drying method should not be
used for hygroscopic samples, as these may absorb moisture
during transfer to another container after having been dried.
Example B
The material to be dried is placed in its container and the con-
tainer is placed in the drying tube. The drying oven must be
operated in the vertical position for this method. The advantage
of this method is that the substance does not need to be trans-
ferred from one container to another after drying, and that its
container can be sealed immediately after drying.
Example C
A hard surface layer is created while drying some substances
which increases the drying time dramatically. This can be avoi-
ded by rotating the container regularly. It is therefore recommen-
ded to use the notched rotation drying flask which can only
be used in conjunction with an electrical ball tube
drive.

Glass Oven B-5855 Operation
5.3.4 Placing the Drying Tube in the Drying Oven
If the material to be dried has been placed in the drying tube
according to Chapter 5..., the tube and the end cap are scre-
wed together. The entire assembly is then placed in the drying
oven and fastened with the screw a. You should ensure that
the stopcock is vertical and that the reservoir in the end cap is
directed downwards.
The oven temperature must be set for drying and, if necessary,
the vacuum must be connected. After drying, aeration follows,
either using the air in the environment or using an inert protective
gas using the corresponding gas connection. The assembly is
taken out of the oven and left to air-cool.
5.3.5 Working with Desiccants
The drying of substance samples containing water can be ac-
celerated and optimized by using desiccants such as silica
gels, CaCl2or P2O5. Such desiccants are placed in the rear part
of the end cap. When filling with a free-flowing desiccant, you
must make sure that the end cap remains clean between the
aeration stopcock and the flange. If dust particles adhere to the
sides, then the end cap must be cleaned afterwards. Otherwise,
there is the danger that of these particles will be taken with the
flow of air when aerating the evacuated drying tube, thereby
adding impurities to the material to be dried.
The safety guidelines on the original packaging of the P2O5/
CaCl2should be observed.
