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.
Do not operate the instrument for purposes other than main purpose.
This instrument is only to be used by authorized people after the user manual has been read.
If the warnings mentioned in this manual are not considered, NUVE will not be responsible
from their results.
