What is a vertical freeze dryer?
1、International standard vacuum pump interface, can be connected with different brands of vacuum pumps
2, insulation cover sealing design, pre-freezing process to reduce the loss of cold, energy saving, no condensation
3, using imported brand compressor, low noise, large refrigeration capacity using self-repeating refrigeration technology, cold trap temperature is lower, more reliable performance
4、Efficient air-cooled condenser, with aerodynamic aircraft blades to improve the cooling capacity, more energy efficient
5, with historical data query function, store nearly a month of historical data; no additional software, directly inserted into the U disk can be exported to the current and historical data
6、Pre-frozen shelf can be used as material pre-frozen, drying shelf, can also be used as a guide barrel to speed up the drying speed; transparent bell-type drying chamber, safe and intuitive
7、Stainless steel material shelf, a variety of spacing can be adjusted, suitable for a variety of different materials freeze-drying
8、Large cold trap opening, no inner coil, cold trap can be pre-frozen for samples, cold trap seamless welding, mirror polishing, rounded bottom design, more easy to clean
9、The cold trap and table surface are stainless steel, corrosion resistant and easy to clean.

How to use the vertical freeze dryer?
To ensure that the vacuum freeze dryer can achieve the ideal freeze drying effect and extend its service life, please pay attention to the following matters.
1. The temperature and humidity of the operating environment of the freeze dryer should be kept at 10℃-30℃ and the relative humidity should be <80%.
2. The working environment of the freeze dryer should be free from conductive dust, explosive and corrosive gases and strong electromagnetic field interference.
3. When the accumulated working time of vacuum pump reaches 200 hours or the colour of vacuum pump oil turns brown, the pump oil should be replaced in time. Prevent the vacuum pump from malfunctioning.
4. Do not switch the refrigerant on and off frequently, and wait at least 3 minutes after the refrigerator is shut down before restarting it to prevent damage to the refrigerant.
5. When shutting down the machine, inflate it first and then turn off the vacuum pump to prevent the vacuum pump from returning oil and contaminating the sample.
6. The connection between the plexiglass drying drum and the main machine is sealed by a silicone seal, the seal should be kept clean to prevent scratching, and the plexiglass should not be wiped with organic solvent.
7. After using the freeze dryer, the moisture inside the cold trap should be wiped clean.
