1. INTRODUCTION
1.1. USE AND FUNCTION
The EN 032 incubator is designed to provide excellent incubation conditions for applications in
biology and microbiology laboratories such as medical and veterinary fields; research and
quality control examinations in pharmaceutical, food and cosmetics industries and
biotechnology.
The incubator provides temperature range between the ambient temperature plus 5C and
80C and keeps temperature stable within given tolerances. EN 32 incubators have timer which
can be programmed up to 99.9 hours including hold position and the incubators stop to operate
after the set time is completed. Cross contamination risk is minimized by means of natural air
circulation.
Stable and homogeneous temperature in the useful volume is provided by means of the forced
air circulation through the stainless steel heaters placed onto the three outer surface of the
useful volume.
The insulation proportional to the dimensions of the incubator not only provides a homogenous
temperature distribution but also makes the operation of incubator economics. The incubator
ensures reliable working conditions by the programmable microprocessor with high control
accuracy. Adjustable safety thermostat offers an additional safety for your operations.
The EN 032 Incubators are manufactured according to the following standards
EN 61010-1, EN 61010-2-010, EN 61000-6-3, EN 50419, DIN 12880.
This device is in compliance with WEEE Regulation.
If mentioned warnings in this manual are not considered, NUVE will not be responsible from
their results.
