  Serum is a commonly used nutrient substance when culturing cells, and the quality of serum is directly related to the growth status of cells. Sometimes we will find that there are flocculent sediments in the   square petg media bottles . In fact, there is no need to be too nervous when this happens. These sediments are mainly the following three types of substances: 1. Fibrin: It is a relatively large precipitate that often appears, which can reach 1-2mm and can be observed with the naked eye. Because serum is collected and processed quickly at low temperatures, some fibrinogen (the soluble precursor to flocculent fibrin) remains dissolved during processing and will Fibrin precipitates from clotting in serum bottles.

This deposit looks like tiny black dots under an inverted microscope, which are often mis

  Square media bottles are mainly used to hold various culture medium, serum, buffer and other solutions required for cell culture. In view of the strict requirements of cell culture tests on consumable products, this kind of packaging needs to go through various tests to ensure that it is qualified before it can be put into use. . Among many testing items, the hemolysis test is a very important one. Cell hemolysis refers to the phenomenon that the cell membrane bursts outward due to osmotic pressure, quick freezing, mechanical force, biological or chemical toxins, etc., resulting in the outflow of cytoplasmic substances. The hemolysis test in culture media bottles is used to test whether samples contain leachable compounds that would cause hemolysis of red blood cells in vitro.

  Serum bottle   is a storage container commonly used in laboratories, and is mostly used to store solutions such as serum, culture medium, and various reagents. There are many suppliers of serum bottles on the market, and the product quality is uneven. So, how do we choose this container? It can be considered from the following aspects:                      FuDau 60ml-Square-PETG-PET-Media-Bottles 1. Product material: The materials of serum bottles generally include PET and PETG. The properties of these two materials are similar, and both have good low temperature resistance and transparency. The difference is that the barrier property of PETG is better than that of PET. If you want to pursue a better solution storage effect, it is recommended to choose PETG material. 2. Production process: At present, the production process used for this kind of packaging container is mostly injection blowing and injection stretch blowing one-time molding process. Relatively speaking, the bottle prod
