1. INTRODUCTION
1.1. USE AND FUNCTION
NC 23B Bench Top Steam Sterilizers are widely used for sterilization of appliances utilized in
general medical applications, dentistry, acupuncture and veterinary sciences. These equipment
are also appropriate for the sterilization of tools and instruments that are directly in contact
with blood or other body fluids (e.g. tools and instruments used at beauty clinics, tattoo centers,
hair-dressers etc.)
NC 23B Steam Sterilizers are manufactured in accordance with EN 13060 standard, which
outlines the general rules for small steam sterilizers and determines the sterilization methods
for specific sterilization loads. According to EN 13060 standard, unwrapped solid loads, solid
porous loads, hollow A type loads, hollow B type loads, single and double wrapped loads can be
sterilized in small steam sterilizers.
NC 23B Steam Sterilizers, come with 5 operating programs for sterilization temperatures of
134°C and 121°C, 2 special programs, 1 drying program and 2 test programs. They can be used
for wrapped or unwrapped, porous textile or hollow loads, metal, glass and rubber materials
that can be sterilized using pressurized and saturated water vapor. NC 23B are not compatible
with liquid sterilization.
The steam is produced by the steam generator. The jacket system which surrounds outside of
the chamber provides temperature homogeneity. Jacket system is also used for pre-heating
which helps to decrease total sterilization cycle duration.
All programs operate full-automatically without user’s interference.
NC 23B steam sterilizers have several safety functions with its integrated safety thermostat,
safety valve and surface thermostat in addition to the safety features of the control system (i.e.
high pressure, high temperature).
NC 23B Steam Sterilizers are designed and manufactured in accordance with international
directives and EN 13060, EN 61010-1, EN 61010-2-040, EN 60601-1-6, EN 61326-1, EN 62304,
EN 62366-1, EN ISO 14971, EN 50419, EN 13445 and EN ISO 15223-1 standards under the
supervision of total quality management systems ISO 9001 and ISO 13485.
This device is in compliance with WEEE Regulation.

Before starting the device, pre-heating must be activated (See Section 6.3.4.1). Pre-
heating helps to heat the load and prevent condensation.
Follow the instructions for loading, otherwise the efficiency of the device decreases
and this situation may cause error.
5.8.5. PACKAGING
In order to store sterile items for a long time, items should be packed prior to sterilization.
Correct packaging of the materials is essential in ensuring that sterility is maintained.
FLASH
SENSITIVE
PRION
QUICK
UNIVERSAL

16
The followings can be used for packaging: metal containers with lids or perforated bottoms with
filters in paper, pouches in paper or polypropylene, medical grade paper.
For packaging, observe the following recommendations (for pouches in paper-polypropylene):
Contents must not exceed ¾ of the volume of the pouch.
The instruments must be positioned so that they can be extracted by their handle.
The sealing strip on the pouch must be continuous with a height of at least 6 mm.

Use materials that comply with EN 868-1 for packaging the materials to sterilize.
Each packaged prepared must indicate the date of sterilization, the type of cycle performed and
the date in which the preservation of sterility expires. This latter value must be established
considering the length of preservation of sterility as indicated by the manufacturer of the
packaging material, the internal procedure used and stocking conditions of the sterilized
material itself.
Instruments packaged in individual pouches have a life (in terms of sterility) of 30 days, those in
double pouches of 60, if kept in closed cabinets. These values are, in any case, to be considered
indicative, in that the date of preservation is influenced by various factors, as the environmental
microbic level, the granulometry of environmental dusts (that act as carriers of micro-organism),
as well as the temperature, pressure and ambient humidity parameters.
5.8.6. LOADING

It is suggested to run a cycle at the beginning of daily work without load.
The way in which the load to sterilize is arranged is also considerably important to sterilization
process. Always observe the explanations indicated in this manual.

The materials to be sterilized shall be disinfected prior to sterilization process.
Do not stack instruments on tray or in basket. Overloading could compromise
sterilization.
It is necessary to leave space between materials to be sterilized to allow the circulation of
steam during the sterilization phase and then to facilitate drying.
Use the load supports, to facilitate the circulation of steam.
Place a chemical sterilization indicator on each basket or tray.
Position the instruments sufficiently distant from chamber walls and from one another that
they remain separate for the whole sterilization cycle.
It is preferable that the sterilization container be made of aluminum, as this metal stores
and conducts heat well, ensuring faster drying than other materials.

17
When arranging sterilization containers, care should be taken that drops of condensate do
not wet items being sterilized beneath, but can flow away to the base of the chamber. The
best arrangement is a stack of sterilization containers of the same size, so that condensate
can flow down the sides.
Figure 6 - Stacked Sterilization Trays
Textiles and instruments should not be sterilized together in one sterilization container.
However, where this is unavoidable, the following rules should be observed:
Instruments and sterilization containers should be placed at the bottom.
Textiles should always be placed at the top.
If sterilization bags and instruments are loaded together, then instruments should be
place at the bottom (Figure 7).
Bigger bags should be placed at the bottom; smaller bags should be placed at the top.
Figure 7
5.8.6.1. TEXTILES
When preparing textiles for treatment in the autoclave, care must be taken that the folds in the
textiles are arranged in parallel, and that the items are packed side by side. This vertical
configuration ensures that channels can form between the textile folds for the air to flow out
and steam to flow in.

18
Figure 8 –Properly Loaded Textiles
When loading sterilization containers with textile items, care should be taken ensure that they
retain their vertical orientation. This would prevent the formation of flow channels for air and
steam.
Do not stack textiles on the top each other as this hinders the penetration of steam
into the packages of textiles.
5.8.6.2. INSTRUMENTS
Ensure that instruments of different materials are separated and placed on different trays.
Stainless steel and carbon steel should not be sterilized touch to each other.
Position the instruments sufficiently distant from one another that they remain separate.
Pay attention to the guidance of the manufacturer of the instrument.
Where appropriate, instruments should be disassembled before placing them in the
autoclave, as this will improve the drying results.
Lubricants in the instruments (as instrument oil) can be hydrophobic and these are
impenetrable for steam. In case of sterilization of these instruments, the sterilization may
fail. Prior confirmation should be obtained from the manufacturer of such agents that they
are in fact suitable for steam sterilization.
Place the instruments in open position and demounted so that steam can penetrate more
efficiently.
Figure 9
5.8.6.3. STERILIZATION BAGS
Sterilization packages can be sterilized either in sterilization containers or sterilization baskets.
To enable better drying,

19
Arrange soft sterilization packages vertically and side-by-side. This allows condensation to
penetrate to the packages, while at the same time preventing possibly bursting at the seams.
Do not allow bags and chamber inside touch each other.
Do not arrange packages as stacked.
Insert tools into separate bags.
While loading paper/plastic sterilization bags, place paper side of a paper/plastic bag towards
paper side of the other bag. Place plastic side of paper/plastic bag toward plastic side of
other bag.
Ensure that space shall be left between sterilization bags.
6. OPERATING PRINCIPLES
6.1. OPERATION PHASES
PRE-VACUUM: As soon as the program is started, the pre-vacuum phase starts to operate.
Pressure in the chamber decreases below ambient pressure by vacuuming the air in the
chamber and steam is blown in to replace the volume of vacuumed air. This phase is repeated
several times depending on the selected program.
HEATING: Steam is charged to the chamber to reach sufficient steam temperature before
sterilization phase.
STERILIZATION: The chamber temperature is kept at the required sterilization degree all
through the sterilization phase.
STEAM DISCHARGE: The pressure in the chamber is decreased to the ambient pressure by
discharging the steam in the chamber after the sterilization phase.
DRYING: Following the steam discharging, the pressure in the chamber is decreased below
ambient pressure. Thus the humidity within the chamber is eliminated throughout the drying
phase.
AIR INTAKE: Following the drying phase, ambient air passing through the filter is taken into the
chamber to break the vacuum and raise the chamber pressure to ambient pressure.

If the lid is not opened after the program is over, another program cannot be started.

When sterilization is completed, condensate may be observed on the sterilized items.
However, it does not show that the sterilization is unsuccessful. The German
standard ‘DIN 58953’ Part 7 Section 7 comments on: “...Small amounts of water on
the surface of packages do not represent a cause for concern if they dry completely
within thirty minutes after removal from a steam sterilization system...”
