How long does the serum separation gel fail after being unsealed

Release time:


Serum separation gel, as an important reagent in clinical medicine, is in its original factory state of transparent or semi transparent gel. The common packaging specification is 25kg barrels, and it needs to be unsealed before use. If it is not used completely, the validity period after unsealing is a concern for many people. Once stored improperly or invalidated, it can have a significant impact on the experimental results. Below, we will focus on discussing the shelf life, storage conditions, and expiration date of serum separation gel after opening.

Shelf life and storage conditions

Usually, the packaging of serum separation gel will indicate its production date and shelf life. These dates will tell you the optimal shelf life of the product under normal storage conditions, which is usually relatively long, 1-2 years. The exact date usually varies depending on the manufacturer and product type. When purchasing serum separation gel, it is necessary to check the shelf life on the packaging to ensure that the obtained product does not exceed its expiration date. In addition, it is important to carefully review the storage recommendations provided by the manufacturer. Generally speaking, serum separation gel can be stored at room temperature without the need for special refrigeration storage.

Validity period after opening

Once the serum separation gel is unsealed, its validity period will be limited and usually shortened, as the reagent will be at risk of contamination and degradation upon contact with the external environment. It is generally recommended to use the serum separation gel after opening as soon as possible, and be sure to check the product for any abnormalities, such as changes in odor or color, before use. The validity period of the serum separation gel after opening is influenced by various factors, including storage conditions, packaging methods, and reagent stability. Therefore, in order to significantly extend the validity period after opening, the following are suggestions for everyone:

1. Storage temperature: The serum separation gel after opening should be sealed in a timely manner and stored within a reasonable temperature range, usually between 2 ° C-8 ° C, to help slow down the degradation rate of the reagent.

2. Sealing: After each use, ensure that the container is tightly sealed and the reagent is well sealed, which can effectively prevent external air, moisture, and pollutants from entering and causing changes in chemical properties.

3. Avoid freezing: Serum separation gel is a type of colloid that can be sealed and stored after being opened. Do not freeze it in the refrigerator as it can cause changes in viscosity and poor performance.

4. Mark the opening date: Mark the opening date on the reagent in a timely manner, so that the remaining validity days can be understood before the next use to reduce unnecessary losses.

5.Manufacturer's suggestion: There are differences in the expiration dates of products from different manufacturers, and the specific usage recommendations provided by the manufacturer after opening should be strictly followed.

The use of expired reagents can cause losses in the experiment. Therefore, it is recommended that when the serum separation gel exceeds its shelf life after being unsealed, even if it appears normal in appearance, it should no longer be used. This is a situation that needs to be avoided in the laboratory. Meanwhile, if any abnormalities occur during use, such as deterioration, odor, or condensation, even if it has not yet reached its expiration date, it should be immediately stopped from use. Abnormal reagents not only interfere with experiments, but may also pose potential risks to laboratory personnel.

In the laboratory, understanding the shelf life, storage conditions, and shelf life of serum separation gel after opening is a part of ensuring the quality of the reagent.
