The CleanVac system is a lab scale freeze dryer using the lyophilization phenomena. The cylindrical shape transparent acryl chamber is used for dry chamber and stainless steel petri dishes are used with rack system to dry the frozen specimen. The CleanVac system has a very large size cold trap that it can be used for prefreezer and it does not need the exclusive prefreezer system.The microprocessor governs the whole system process that it monitors the temperature with pt100 temperature sensor and vacuum level with pirani gauge. The microprocessor automatically decides the leak condition from the vacuum level and give a warning to the LCD display in order to prevent the damage of vacuum pump by overflow of the molten specimen. Furthermore, the microprocessor periodically stops the vacuum pump and measures the change of vacuum level to find out the end of freeze drying procedures. |

■ Lyophilization is the most way to preserve living cells,
whole blood, vaccines, biological specimens, vegetable,
meat, fish and general food.
■ The powerful compressor with CFC-free refrigeration
system can pull down the temperature of the cold trap
to -85'C.
■ Removable front of panel provides easy access to
refrigeration system and pump for maintenance.
■ High capacity refrigeration system ensures rapid
cooling.
■ The vacuum pressure is precisely measured by Pirani
vacuum gauge.
■ The microprocessor governs the whole system and all
the parameters are displayed in the LCD display.
■ Self diagnosis algorithm for check the end of the freeze
drying procedure: Stop the vacuum pump for each hour
and check the pressure change during a minute. If the
value of pressure change is limited in the predetermined
range, the controller automatically displays the end of
the drying procedure in the LCD panel.
■ The heater plate can be installed to the rack for petri
dishes in order to accelerate the drying speed.
■ LCD display shows the vacuum pressure, chamber and
trap temperatures, and the other processing parameters.
