modified value is underlined. When the date and time values are correct
confirm the settings using the ok button on the bottom of the screen.

4.3. Preparation for sterilization

liquids can be sterilized in glass containers (flasks) of capacity in the range
from 100 to 500 ml. it is possible to use the containers made of plastic
materials – certified to be sterilized at temperature of 135°c.
Only one flask, regardless of its size, can be placed in the process
chamber for sterilization! It is recommended to place the flasks centrally,
in the middle of the process chamber.
the flask in the chamber can be closed with the aluminium foil, stopper
made of plastic material (resistant to high temperature), glass or metal. it is
important that the stopper is not tight to enable the compensation of pres-
the device is equipped with a real
time clock for storing the process
data and process run time on the
memory card. should the date and
time stored in the data log be inad-
equate, the user can adjust the time
and date on the settings screen.
accessing this screen is possible by
touching for 5 seconds the upper left
corner of the Hello screen. after that
the date and time settings screen will
be displayed. changing of the de-
sired value is possible after touching
it and adjusting using the + and –
buttons on the left of the screen, the
sure between the flask interior and the process chamber.
the device was optimized for a wide range of volumes – see table 1 (the
volume lower than recommended may cause over-heating of the sample
whereas, while the higher one may cause boiling of the medium during the
cooling phase).

4.3.1. containers

the unit was optimized to be used with all types of labora-
tory flasks, both with narrow and wide neck and bottles de-
signed for autoclaving. all types of glass, commonly used to
produce these types of flasks, enable to obtain appropriate
parameters. also the flasks made of plastic materials assure
proper parameters, providing these are made of material re-
sistant to temperature over 135°c.
The standard flasks made of polypropylene (PP), resistant to tem-
perature of 121°C ARE NOT suitable (they undergo deformation).

4.3.2. Media

the capacity of used flasks should be selected in such a way
that the volume to be sterilized comes within the recom-
mended optimal range!
Remember NOT to exceed the recommended volumes; too
low volume of a liquid in the flask can cause its over-heating,
whereas too high volume can cause its boiling over during
the cooling phase.
solutions containing completely dissolved components (already before auto-
claving) can be sterilized smoothly in the entire range of acceptable volumes.
