Every step in the experiment is important, ignoring any one of them may lead to the failure of the experiment. Good habits can improve work efficiency and reduce experimental costs! Good experimental habits are also the foundation of successful experiments.

Sometimes many people know that their actions are wrong, but they have become accustomed to them or keep making mistakes to save trouble. This not only brings uncertainty to their experimental data, but also affects others, which is not worth the loss. Let's take a look at some bad habits in the laboratory? Have you been hit?

When it comes to the most common bad habits of experimenters, what comes to mind?

Let's take a look at the bad habits summarized by netizens together.

Bad habits during the experimental process:

When weighing or measuring samples, record the data on a draft paper first, and after the sample is completed, copy it into a notebook;

Sometimes the experiment is completed before filling in the records uniformly;

Before the instrument drops below its limit, it begins to shut down;

When performing gas chromatography analysis, simply rub the needle of the syringe with your finger without wiping it with filter paper.

Bad habits in the pre-treatment process before the experiment:

When weighing samples, repeatedly use weighing paper;

Do not perform acid-base configuration in a fume hood;

Sometimes weighing or other operations are carried out without wearing gloves;

At the end of the volume adjustment process, a dropper is not used, but a washing bottle is directly used. The volume adjustment is not very accurate, and it often exceeds the scale line after being left to stand;

Before weighing, do not calibrate or check if the horizontal bubble is in the center zone.

Use a medicine spoon to retrieve the ingredients, and return any excess medicine to the bottle.

Bad habits after completing the experiment:

The laboratory waste liquid is directly poured into the sewage tank instead of being treated and recycled;

Disregarding the cleanliness of the table after the experiment is completed;

After using the balance, do not close the balance door.

Bad habits that affect others

The most important issue is the standardization of experimental operations, such as the conservation of reagents, the care of instruments, and so on. Mild cases involve problems with one's own experiments, while severe cases can affect the atmosphere of the laboratory. For example, if the experiment is not cleaned up in a timely manner after completion, it will always leave others with a mess; Long term occupation of laboratory public computers, online chatting and gaming, hindering others from searching for information; Public instruments are not taken care of, and after being damaged, they are concealed and not reported, shirking responsibility.

The bottle is not labeled, so I don't know what's inside.

The configuration information on the standard solution bottle is lazy and not updated.

Frequent and unplanned opening of the refrigerator, with the refrigerator door wide open for certain operations. Causing unstable temperature in the refrigerator, which affects the freezing effect of other stored items. Randomly rummaging through the items placed inside makes it difficult for later people to find their belongings.

The opening of the cell culture chamber door is too large, too frequent, and not closed in time, resulting in a decrease in the temperature and carbon dioxide concentration of the chamber. Observing cells cultivated by others without their consent. Sometimes, when cells are in need of stillness, unauthorized inspection by others may affect cell adhesion.

Items disinfected by others were opened without permission in the ultra clean bench. Not informing later and repackaging.

Gloves that are worn on hands and have toxic substances (such as EB, PMSF, etc.) stuck on them, including door handles, keyboards, etc. Causing others to indirectly adhere to such toxic substances with bare hands.

Bottles with toxic substances are not given special treatment and are placed together with other bottles.

Randomly writing on the label of public reagents, indicating one's own dosage, affects the use of future generations.

After using the centrifuge, microscope, etc., leave without turning them off.
