ASI 400 Air Stream Incubator
The ASI 400 Air Stream Incubator provides critical maintenance of physiological temperatures on
unenclosed microscope stages and can be used with a variety of instrumentation where precise control
above ambient is required. This highly versatile, remote incubator provides a non-cyclical,
electronically controlled air stream assuring maximum temperature stability and complete access
to both the specimen and equipment. Originally designed by Nicholson Precision Instruments, Inc.,
to work in partnership with the DSC200 Culture Chamber, the ASI 400
has been known in laboratories around the world for over 30 years as a reliable, highly versitile tool.
Manufactured only by NEVTEK the ASI 400 Air Stream Incubator is uniquely designed to guarantee:
Precise Control: Temperature control of better than ± 0.2șC is achieved by means of a
state-of-the-art proportional controller. A quick response thermo-sensor monitors the temperature
of the high-velocity air stream. The non-cyclical, temperature controlled stream of air is focused
directly on the culture chamber, microscope stage, condenser and objective, the area requiring critical
temperature control. Delicate optical equipment is further protected from deleterious temperature
changes by means of an electronic fail-safe device built into the ASI 400 incubator. There is no need
to enclose the microscope. The problem of differential heating of specimen and equipment as occurs with
infrared stage heaters does not exist. The temperature of the specimen is stabilized rapidly. The
filtered, high velocity air stream inhibits interference from room air currents and prevents dust
Direct Access to Specimen and Equipment: Obstructions to access are completely eliminated.
The remote location of the incubator assures that all manipulations can be performed rapidly and easily.
Versatility: The ASI 400 Air Stream Incubator is completely adjustable and can be used with any
light microscope, upright or inverted.

In addition, it can be used in other environments where precise
temperature control is required, i.e., for temperature control of the cell suspension in flow cytometry;
with microinjection apparatus to provide temperature stability during delicate microsurgical procedures.
Compatibility: Todays biology labs are filled with expensive electronic equipment which can be
sensitive to radio frequency interference, therefore the temperature controller in the ASI 400 uses zero
voltage switching to eliminate RFI. The ASI 400 also has heavy RFI filtering on the power line. These
design features along with the aluminum cases eliminate problems with both radiated and conducted radio
Economy: The versatile ASI 400 Air Stream Incubator provides maximum performance at an affordable
price and is designed and constructed to provide years of trouble free, continuous service.
