Quotation for laboratory freeze dryer

Laboratory Freeze Drying Machine FD-1A-80+：

Under low temperature and vacuum conditions, the water and other solvents in the frozen sample are removed from the sample by sublimation, resulting in a dry state of the sample. During the entire freeze-drying process, the spatial structure of the sample remains unchanged and is easily redissolved, ensuring the activity of the sample. Therefore, it is very suitable for drying heat-resistant substances such as enzymes, hormones, nucleic acids, blood, and immune products.

1. Vertical design, compact, occupying a small tabletop.

2. Beautiful appearance, ergonomic design, and easy operation.

3. Brand compressor（SECOP）Efficient and reliable, with low noise

4. The cold trap has a large opening and a sample pre freezing function.

5. The cold trap is made of all stainless steel, with no coils inside, and is smooth and corrosion-resistant.

6. Design a guide tube to increase the effective area of the cold trap and facilitate rapid freeze-drying.

7. Inflation valve, can be filled with dry nitrogen or inert gas.

8. Transparent drying chamber, mold injection manufacturing, non adhesive, no leakage.

9. Standard vacuum interface, can be used in conjunction with various vacuum pumps.

10. Display temperature and vacuum curves and data, which canUExport data from the disk.

Laboratory Freeze Drying Machine FD-1A-80+：

Freeze dried products have poor rehydration, poor clarity, or the presence of impurity particles. The cause of such problems is improper control of solution formulation or freeze-drying process. If the concentration of the substance is too high, or if the temperature rises too quickly during the sublimation stage, the product will undergo local melting and concentration, forming small hard lumps after freeze-drying, resulting in poor solubility and clarity. The solution is to reduce the solution concentration or appropriately lower the sublimation stage temperature. Another possibility is that the reverse diffusion of silicone oil or vacuum pump oil vapor may result in poor clarity or impurities after reconstitution.

Prepare frozen materials:

1.Before the experiment, the material to be tested should be placed in a low-temperature cabinet such as a refrigerator or freezer and frozen at a certain temperature≤-30℃The freezing time shall not be less than48hour The materials required for the experiment must be frozen solid.

2.The pre freezing temperature varies depending on the freezing point of the test material, and the test material must be fully frozen.

3.If the test material is a suspended liquid, the liquid solution should be centrifuged and precipitated before freezing, and then pre frozen to increase the freeze-drying speed.
