4.1 Definition of use
The K-SYSTEMS Kivex Biotec G85 CO² Bench Top incubator is designed for keeping
gametes and embryos in a controlled environment.
4.2 General description
The chambers and aluminum warming blocks maintain a preset temperature in the range
ambient to 42° C. The temperature is electronically controlled by a PID controller and can
be read on the displaying increments of 0.1° C.
The G85 features heated lids. The bottom part is made from thick aluminum that gives
ideal temperature distribution. Back part that houses the electronic is made from stainless
steel. Interchangeable aluminum Warming blocks holding a variety of culture dishes are
available.
The G85 features a built in digital flow meter with a possible flow of 0 - 29 liters per hour
and a humidification system.
The G85 has also a purge function enabling a quick CO2 level recovery within the
chambers. The recovery time is 15 seconds with a pressure of 0.5 bar.
Note The atmosphere in the chambers may be controlled by flushing with a gas mixture.
Use only 5% CO2 in air.

5 Features and operation
5.1 Assembling the G85
No assembly needed. Just follow directions in section 5.2 and the unit is ready for use.
5.2 Connection to the mains
The mains voltage is automatically regulated to the correct level by the main adapter
(PSU).
Connect the G85 to the mains supply using the enclosed PSU.
For safety reasons the unit has an external PSU which operates at a low voltage.
5.2.1 Start of apparatus
Connect the unit to the PSU and the PSU to the mains wall socket.
To power up the unit, press the heat on button on the keyboard. The display will indicate
the current temperature.
The aluminum dial on the side of the G85 can be turned and the gas flow level is adjusted.
The valve controlling the flow is a precision valve with a short span from closed to open, so
adjust with slow movements. A hint for adjusting is to close it fully and then open it gently.

arrow DOWN key to
raise or lower the set
temperature.
When the desired
temperature is
reached, let go of the
setpoint key.
Note The setpoint can be adjusted to a reading between ambient and 49.9 ˚C.

5.7 Gas flow setting
The display can switch between temperature and flow rate.
The flow rate is shown in the display by the integrated digital flow meter in the G85.
Action Key
Press arrow key either up or
down one time.
Now the flow rate in liter per hour
will be shown.
The flow rate can be adjusted between 0 – 29 l/h.
If the flow becomes larger that 29 l/h the display will indicate “Hi” (see section 5.8).
Action Key
Press arrow key either up or
down once again to change to
the display of temperature.
5.7.1 Why gassing?
Most of the culture media which are used in assisted reproduction techniques are sensitive
to changes in pH. Culture media must be maintained at a pH about 7.4. This can be
obtained by gassing with atmosphere of 5% or 6% CO2.
5.7.2 Working gas pressure
Working gas pressure (inlet pressure on the G85) must be regulated to 0.5 bar by a
reduction valve. The reduction valve must be a high quality unit of the pressure type that
can be adjusted precisely in the 0-1 bar range.
The flow rate on the G85 must be adjusted to a specific level in accordance with the use of
the unit.
Frequent openings of the lids will require higher flow rates.
Note Any use of flow type regulators or inadequate quality pressure type regulators will
cause the flow on the G85 to be unstable and drift.
Below is listed the full recovery rates for CO2 level in both chambers in minutes.
This can be used as guideline for the use.
Flow (l/h) * 10 28 50
Time (min) ** 12 2.8 0.9
*Flow setting in display of G85.
**Time it will take to recover CO2 level after a chamber has been opened at the above flow
setting.
