GD-5 plasma cleaner is with 5 L plasma chamber and 40 kHz IF power supply. The chamber is Φ150*280（D）mm with a tray 230(L)*120(W) mm. GD-5 plasma cleaner is laptop and can be all-round treatment the irregular products with different size. It is widely apply for R&D in university , research museum and small industry production.
Vacuum plasma cleaner with PLC+touch screen control , it is convenient operation. About the treatment operation , it has two operation mode , manual mode and auto mode, you can choose the mode according your need.
Glass freezing rod, also can be called glass freezing tube or glass freezing rod. In 1998, an open freezing carrier specially designed for vitrification was invented by Professor Gabor Vajta, which is considered one of the most rapid methods of glazing freezing. The glass freezing depository tube consists of a frozen depository tube and a protective tube, with a box of five colors, which can be suitable for the cryopreservation of ovum and embryos of various periods.
Because the glass rod needs to be placed in an ultra-low temperature environment, its material needs to have the characteristics of low temperature resistance. At the same time, in order to ensure the survival rate of human oocytes or embryos, the freezing rod must be sterilized and free of other pollutants.
PC plastic, colorless and transparent appearance, low temperature resistance can be up to -100-150 degrees, is one of the best low temperature resistance materials, but also has a strong wear resistance and heat resistance. Therefore, PC polycarbonate, which can withstand low temperature and make it convenient for observation, is an excellent material for making glass freezing and freeze drying. The only drawback is that the hydrophilic of PC is too poor.
The water absorption rate of PC is about 0.03% to 0.04%, and the surface energy is relatively low, that making it difficult to make adhesion or coating on the surface. However, through the plasma surface modification, the active functional groups such as hydroxyl and carboxyl groups can be formed on the surface, which can significantly improve the interface activity and enhance the affinity.
As for how to deal with the pollutants on the freezing storage rod, it is the advantage of the plasma cleaning machine. Compared with the traditional wet treatment, the advantage of plasma cleaning technology is that it can not only do not leave pollutants on material surface, but also effectively remove the original remaining pollutants in the cleaning process. This is the decomposition and discharge of the plasma is catalyzed by electric energy, which is a clean energy, and the cleaning process does not add other chemicals.
In the plasma activation cleaning, weak chemical bonds are easily interrupted by plasma ionization of high energy ions, so that the pollutants are oxidized decomposition, even if the pollutants remain on the very complex shape surface, can also be removed by the plasma cleaner.
For the special purpose of the glass frozen storage rod, we choose to use the vacuum type plasma equipment for treatment. Vacuum plasma cleaner are not only limited by the shape, material and application, but also environmental protection, safety and high efficiency characteristics. After treated by the plasma cleaner, we using water contact measurement equipment for test the material surface hydrophilic. After water drop on the material surface , it was attach on material surface and spread instantaneously. It proof that the surface hydrophilic of vitrified cryopreservation rod is highly improved.
We have more expensive about plasma cleaning PC material , welcome sent us inquiry if you need such kind demand. We believe that can help you.
