About the use of freeze dryer

Freeze dryer boot operation
01. Open the main power switch on the left side of the chassis, and the air pressure is displayed as atmospheric pressure 110pk;
02, press and hold the total opening key on the control panel for more than 3 seconds, the temperature is displayed as the actual temperature of the cold trap;
03. Start the refrigerator and pre-cool for more than 30 minutes;
04. Put the sample into the sample holder, cover the plexiglass cover, and start the vacuum pump;
05. After the gas pressure is stable, record the temperature and pressure values.

Freeze dryer shutdown operation
01. Record the temperature and pressure values ​​before the shutdown;
02, press and hold the inflation valve of the control panel, and immediately turn off the vacuum pump;
03. When the pressure is displayed at atmospheric pressure, open the plexiglass cover and take out the sample;
04. Turn off the refrigerator, press and hold the total switch key for more than 3 seconds, and finally turn off the main power switch;
05. After the ice in the cold trap is completely turned into water, open the water outlet valve on the left side of the cabinet to release water, and clean the inner wall of the cold trap with a dry cloth, and cover the large filter paper to prevent dust.

Other matters needing attention
01. Prepare samples to maximize their surface area, which should not contain acid-base substances and volatile organic solvents;
02, the sample must be completely frozen into ice, if there is residual liquid will cause gasification jet;
03, pay attention to the cold trap is about minus 65 ° C, can be used in low-temperature refrigerators, but must wear thermal insulation gloves to prevent frostbite;
04. Before starting the vacuum pump, check whether the water outlet valve is tightened, whether the inflation valve is closed, whether the contact surface of the plexiglass cover and the rubber ring is clean and free of dirt, and is well sealed;
05. Under normal circumstances, the machine must not be used continuously for more than forty-eight hours;
06. During the freezing process, the temperature gradually decreases. The sample can be taken out for a period of time (still in the frozen state) and dried to shorten the drying time.
