Bad habits during the experiment
1. When the sample is weighed or measured, the data is first recorded on the draft paper, and the sample is finished and then copied to the record book; sometimes the record is completed after the experiment is completed;
2, the steps that need to be timed, using the time on the phone or computer, the control is not strict;
3. When analyzing by gas chromatography, the syringe needle is directly rubbed with a finger and wiped without filter paper;
4, after washing the hands directly rubbed in the butt position of the white coat;
5, in order to save trouble, the laboratory door is often not closed, resulting in environmental conditions are not effectively controlled;
6. If the instrument has not fallen below the limit, the instrument will be turned off;
Bad habits of pre-processing
1. Before weighing, do not correct, do not see whether the horizontal bubble is in the center;
2. The balance begins to weigh and count before it is stable.
3. When using the balance, you like to press the button with your fingertips, and the buttons are all broken;
4. When weighing the sample, repeat the weighing paper several times;
5. Sometimes do not wear gloves for weighing or other operations;
6. When the acid and alkali are configured, they are not carried out in the fume hood;
7. The final link does not use the dropper, but directly uses the bottle, the volume is not very accurate, often it will exceed the tick mark after standing;
8. When the volume is constant, the volumetric bottle calibration line is not looked at;
9. when looking at the titration, do not take the titration tube, look directly;
10. The steps are not recorded when the solution is configured;
11. Use the medicine spoon to take the material, and the excess medicine is still returned to the bottle;
12. Do not pay attention to the wear in the experimental area: slippers go up and down, sometimes do not wear the white coat, take items with bare hands;
Bad habits after the experiment is completed
1. The laboratory waste liquid is directly poured into the lower pool instead of being treated for recycling;
2. After the titration is completed, the liquid in the burette is not poured out in time, and sometimes it will be placed for a long time;
3. Used flat plates and culture liquids are thrown away by hand;
4. After the balance is completed, do not close the balance door;
5. Put the special clothing for the laboratory outside the laboratory, such as the canteen;
Bad habits affecting others
The most important are the problems of experimental operation specifications, such as the saving of reagents, the care of instruments, etc. The light ones are problems of their own experiments, and the heavy ones are the problems that affect the laboratory, such as:
1. After the completion of the experiment, the site will not be cleaned up in time, and a mess will be left to others;
2. Long-term occupation of laboratory public computers, online chat games, obstructing others to check information;
3. public instruments do not care after the damage is concealed and not reported, shirking responsibility;
4. the bottle is not marked, do not know what is inside it;
5. The configuration information on the standard solution bottle is lazy and not updated;
6. The frequent and unplanned opening of the refrigerator, and the refrigerator door opened for some operations, resulting in the unstable temperature of the refrigerator, affecting the frozen effect of other placed items;
7. Turning over the items placed in it, so that later people will have to work hard to find their own items;
8. Put food, ice cream, bread, and other foods in the freezer where the inspection items are stored;
9. The items that have been disinfected by others are not opened privately in the ultra-clean platform. After re-packaging without notifying;
10. wearing gloves on the hands, and sticky with toxic substances (such as EB, PMSF, etc.), including door handles, keyboards, etc., causing others to barely stick to such toxic substances;
11. Bottles with toxic substances are not given special treatment, but are put together with other bottles;
12. Scribble on the label of the public reagent, indicating its own dose, and affecting the use of future generations;
13. The guns are placed indiscriminately, and the gun racks are not put back. The gun heads in the clean bench are not spilled;
14. When the pipette is used up, the maximum scale is not immediately adjusted, so that the spring of the gun is well rested;
15. the PCR instrument, is not finished in time to complete, the PCR instrument as a 4 ° C refrigerator, affecting its life;
16. Some things that are out of date are not cleaned up in time. For example, the cultured dishes are placed in the refrigerator, the laboratory plates are not enough, and the refrigerator is crowded;
17. After the electronic balance is used, it will not be cleaned up in time. The residual weighing object is in the balance and on the work surface, which affects the service life and accuracy of the electronic balance;
18. Do not let the air go out after the alcohol lamp is turned off. After the alcohol lamp has been used up, do not remove the cover and cover it once. When someone else uses it next time, the alcohol lamp will vacate a high flame and easily burn people;
19. do not pay attention to save energy, the computer does not shut down, the centrifuge is not in the state of refrigeration at night, open the refrigerator door for a long time, open the lid of the water bath is not closed, do not turn off the lights when leaving, air conditioning to open overnight.
