3. General information
S-Bt Smart BioTherm is designed for work in the areas of cell biology (operations
with animal cell cultures and tissues), molecular biology (DNA/RNA reaction analysis, hybridization reactions), biotechnology (synthesis of target proteins and other molecules) and
immunology (synthesis of antibodies and other proteins of immune system).
Unit provides a six-sided heating: the heating elements are located on the walls and
on the door, thus providing excellent uniform temperature distribution, regardless of external
factors, such as ambient temperature and positioning of the device.
Built-in infrared CO2 sensor allows accurate control of the CO2 level. The sensor
makes measurement non-sensitive to changes in temperature and humidity inside the incubator.
The chamber is made of stainless steel with smoothed seams to minimize contamination and to facilitate cleaning.
S-Bt is equipped with a UV air recirculation system — 1 UV lamp and a fan are
mounted behind the rear wall, providing decontamination of the working volume.
A convenient access port is built in the wall of the incubator for easy output of wire
sensors or devices' installed inside. The access port is heated independently to prevent formation of condensate.
Unit is equipped with error tracing and alarm systems, which significantly lower potential risks during operation.
Unit is equipped with a "black box" system that records temperature, humidity and
CO2 levels as well as statuses for door opening, UV lamp, fan and errors to the inner
memory.
Bluetooth connection to PC is available.
Application areas:
Cell biology: operations with animal cell cultures and tissues

9.2. All maintenance and repair operations must be performed only by qualified and spe-
cially trained personnel.
9.3. Regular service schedule
9.3.1. After operation. Switch on the recirculator running for 1 to 3 hours in an empty incu-
bator to decontaminate air in the incubator. To switch on the UV recirculator, see
5.9.1.1. After decontamination, slightly open the incubator doors – UV lamp has been
known to produce reactive oxygen species in minor concentrations.
9.3.2. Monthly (more frequently, if necessary):
- Rub the inner surfaces, water pan with lid and shelves of the incubator with 75%
ethanol solution or other acceptably disinfectant such as sodium hypochlorite solu-
tion, and allow them to dry.
- After cleaning the glass door, rinse with water and dry the excess to avoid streaks
and possible corrosion.
- Remove dust with moist cloth piece from outer incubator surface, especially front
screen and upper part of the incubator.
- Visually check the hydrophobic filter (see 9.7) and access port seal (see 9.8) and
replace if necessary.
- Check the accuracy of CO
tion with a reference CO2 analyser.

9.6. UV lamp replacement. Average lifetime of the supplied UV lamps is 9000 h. Re-
placement is necessary after lamp stops functioning or at the end of manufacturer
specified lifetime. Only the persons who have completed special training are allowed
to perform lamp replacement. UV lamp operation lifetime is checked and tracked by
the incubator.
9.7. Hydrophobic filter replacement. The filter should be replaced when it becomes
glazed with dirt or with sucked liquid. Maximum time of use is 30 days. We recom-
mend replacing the filter immediately after full cycle of maintenance.
Close the CO2 valve on the gas reservoir and turn off the unit. Remove the filter from
the tubing. Insert a new filter into the socket and tighten it. Pay attention that “IN”
marking must be facing right side when viewing the incubator from the front.
9.8. Access port seal replacement. To prevent possible contamination of access port
seal (made from foamed polyethylene) and to ensure complete sealing of the port,
the seal should be replaced after 30 days from the first operation.
9.9. Calibration. Recalibrate the unit after the date on calibration certificate. To complete
the process, contact Biosan or your local Biosan representative.
