I don't know if you noticed it. There is a small piece of painted mark on the HPLC vials. It is not for the sake of good looks.
When buying, it is best to buy bottles of different colors. For example: your laboratory will open two A and B projects at the same time. The first A project uses a white sample vial, and the B project uses a blue vial. After the test is completed, it is cleaned according to the above method. The second experiment is performed. At the time, the A sample uses the blue sample bottle, the B item uses the white sample bottle, and so on, which can effectively avoid the trouble that the pollution brings to your work.
At last:
1. Several instrument engineers have suggested: use the muffle furnace to bake for about half an hour at 400 degrees, and the organic things are basically gone;
2. Place the sample bottle in a muffle furnace and dry at 300 °C HPLC vials.
This is the end of the introduction of It is recommended that you purchase HPLC vials of different color markings. I hope it can help you.
