Capacity limit: The amount of liquid injected should not exceed 2/3 of the volume of the conical bottle, especially when heating operations are carried out to prevent the liquid from overheating and expanding and splashing. Although large conical bottles have large capacity, they also need to comply with this principle.

Heating operation:

When heating, asbestos mesh or special heating pad should be used to avoid direct contact with the heat source of the conical bottle resulting in rupture.

The heating process should be evenly heated to avoid local overheating.

Before heating, ensure that the outside of the conical bottle is dry to prevent cracking caused by over-cooling.

Stirring and oscillating:

When mixing, the glass rod of the appropriate length should be used to avoid the mixing rod touching the conical wall or the bottom of the bottle resulting in cracking.

When oscillating the conical bottle, it should be rotated in the same direction to avoid liquid splashing.

Cleaning and drying:

After use, the conical bottle should be cleaned immediately to avoid the residue is difficult to remove after drying.

Special detergent can be used for cleaning, and ultrasonic cleaners can be used for cleaning if necessary.

After cleaning, the conical bottle should be thoroughly dried to prevent internal residual moisture from affecting the experimental results.

Storage and protection:

Conical bottles should be stored in a dry, cool, ventilated place, away from direct sunlight and high temperature environment.

Avoid the conical bottle being hit or squeezed to avoid cracking.

Use special stoppers: Make sure to use a cork or rubber stopper that matches the conical mouth of the bottle to prevent leaks.

Avoid chemical corrosion: Pay attention to the material of the conical bottle and the range of chemical substances tolerated, and avoid the use of chemical reagents that will corrod the conical bottle.

Marking and identification: Conical bottles containing different reagents should be clearly marked to prevent confusion.
