How to shut down the four-ring lyophilization experimental lyophilizer

Lyophilizer, lyophilization technology is a technical method
of pre-freezing water-containing articles and then sublimating their moisture in a vacuum to obtain dried items.

The lyophilized treated items are easy to store for a long time, have good rehydration and retain their original biochemical properties
.

They are widely used in medical pharmaceuticals, biological products, food industry and new materials
.

There are many
uses for the four-ring lyophilization experimental lyophilizer.

1.
It can be used for the drying of products that are easy to dehydrate, to ensure that the product can restore the characteristics of raw materials after adding water, and does not affect the gas aspect of the
product.

2.
It can keep the protein in a anhydrous state at low temperatures and keep its original characteristics unchanged
.

3.
Keep tissues, tissue extracts, bacteria, blight bacteria and other materials in a dry state, without chemical and other reactions
.

4.
It is a special method
for maintaining biologically sensitive substances.

5.
In terms of experiments, biological or chemical materials can be frozen dried to observe their internal structure
.

For the operation of the four-ring lyophilization experimental lyophilizer, since there is a good start, it is natural not to be sloppy when shutting down and shutting down, and it is also necessary to follow the correct steps to operate the shutdown
.

1.
Insert the quick inflation valve connector into the fast inflation valve seat, and turn off the "four-ring pump" power switch at the same time, so that the air slowly enters the cold hydrazine; If an inert gas needs to be filled, the decompression conduit of the inert gas is connected to the "inflatable port"; 2.
Turn off the "four-ring meter" and "refrigerator", if you do not need it for a long time, you should unplug the power cord; 3.
Lift the plexiglass cover, take out the item, save it, and freeze-dry it; 4.
After the ice in the cold hydrazine is turned into water, the water needs to be removed from the rapid inflation valve, and the operation is similar to inflation; 5.
Clean up the moisture and impurities in the cold hydrazine and properly maintain the equipment; 6.
Multi-manifold type, the rubber valve should be closed one by one and the lyophilized bottle should be removed before repeating the shutdown operation
