In the 21st century, driven by rapid economic development, people’s lives are getting better every day. Wine, especially imported red wine, will also become our essential product for pursuing a healthy life. Unlike other alcoholic beverages, wine is the only base. Alcoholic drinks have many benefits for our health. However, no matter what kind of wine, it should be appropriate to drink. After research by experts, the daily consumption of wine is preferably around 250ml, preferably no more than 300ml. Everyone knows that a bottle of wine is 750ml. It takes almost three days for a person. Only after drinking a full bottle of wine, as we all know, the wine is most afraid of being in contact with the oxygen in the air. Then the question is, how should the bottled wine be kept?
As I said before, wine is most afraid of coming into contact with oxygen in the air. This is mainly because once the wine is in contact with the air for a long time, it will quickly oxidize and become acid. Oxygen can make the highly flavored wine become under the action of acetic acid bacteria. No characteristic vinegar. Therefore, the most important thing in saving open wine is to find ways to avoid contact between wine and air. So, what methods can keep fresh grapes after opening the bottle?
First, refrigerator
For those of us who have no professional wine storage equipment, the refrigerator is the ideal place for daily refrigeration. Put the bottled wine from the new stopper into the refrigerator, and the low temperature of the refrigerator can effectively reduce the speed of the wine after the bottle is opened. In addition, low temperatures can also slow the impact of acetic acid bacteria on wine. However, in this case, it must also be consumed within one week.
Second, the vacuum pump isolation method
Since it has been mentioned that avoiding contact with air is the key to keeping wine fresh and open, this is the most direct method of implementation. The so-called vacuum isolation is the use of vacuum pump to extract the air in the bottle, this method of preservation and aging is much better than the refrigerator. However, there are also imperfections. This is because the vacuum pump will pump away all the gas in the bottle (including the complex aroma produced by the wine) and will affect the flavor of the wine.
Third, change the bottle
Everyone knows that wine bottles have different sizes. The most common is usually the standard 750ml, in addition to the 375ML half bottle, and 187ml small bottle. This vial is a good helper for changing bottles. The unopened large bottle of wine is packaged in a vial and covered with a cork. This method can preserve the opened bottle of wine for a longer period of time. However, this method must be noted to keep the vials clean and dry.
In addition to the inert gas separation method, it is not recommended because it will have an adverse effect on the quality of the wine. In particular, high-quality wines, inert gas will be more self-evident. . Therefore, we recommend the above three methods, but the three methods should be noted that: After opening the bottle should be implemented as soon as possible, if placed in the air for too long, the liquor has been oxidized, which is to think about preservation It is already too late.

Freeze-Dried RT-PCR Test Reagent Kit Of COVID-19(ORF1ab,N)
The Freeze-Dried RT-PCR Test Reagent Kit is a real-time reverse transcriptase (RT)-PCR test intended for the qualitative detection of nucleic acid from SARS-CoV-2 in nasopharyngeal swabs, oropharyngeal (throat) swabs, anterior nasal swabs, mid-turbinate nasal swabs, nasal aspirates, nasal washes, bronchoalveolar lavage (BAL) fluid and sputum from individuals suspected of COVID-19 by their healthcare provider. Results are for the identification of SARS-CoV-2 RNA. The SARS-CoV-2 RNA is generally detectable in respiratory specimens during the acute phase of infection.
Positive results are indicative of the presence of SARS-CoV-2 RNA; clinical correlation with patient history and other diagnostic information is necessary to determine patient infection status. The agent detected may not be the definite cause of disease. Positive results do not rule out bacterial infection or co-infection with other viruses.
Negative results do not preclude SARS-CoV-2 infection and should not be used as the sole basis for patient management decisions. Negative results must be combined with clinical observations, patient history, and epidemiological information.
